The 10 best pre-workouts of 2024, according to experts
Our team of fitness and nutrition experts tested over 50 pre-workouts against a variety of criteria including safety and third-party testing, price per serving, effectiveness, taste, and more. These are the top pre-workouts that made the cut.
In order to provide best insight on pre-workout formulations and relevant research, we consulted with Dr. Robert Wildman, a registered and licensed dietitian who works with professional and elite athletes to achieve their highest level of performance.
When you’re committed to crushing every workout to achieve your fitness goals, experiencing a low-energy, sluggish training session can be disheartening. It happens to the best of us, but a pre-workout supplement could help reduce those occurrences. These supplements are popular for their potential to boost energy, focus, and endurance—ultimately leading to more goal-crushing gym sessions.
Our team of certified personal trainers, nutrition experts, CrossFit coaches, and competitive weightlifters has tested over 50 pre-workouts. We’ve combined our heads to identify 10 of the best pre-workout supplements. Whether you want to improve focus, get leaner, or gain muscle, there’s a pre-workout on our list.
Best pre-workout overall
Transparent Labs Bulk takes the cake as the best overall pre-workout. It contains potent dosages of research-backed ingredients to help you feel improved energy, focus, and endurance for your most effective workouts yet.
Medical disclaimer: This article is intended for educational and informational purposes only. It is not intended as a substitute for medical advice. For health advice, contact a licensed healthcare provider.
Pre-workout is a multi-ingredient supplement you take before your workout to enhance energy, focus, and muscle-building. (46) Ingredients in a pre-workout vary, but many contain caffeine, a well-known stimulant that supports energy and focus. (46)
Other ingredients you may find in a pre-workout include:
Beta-alanine: A precursor to carnosine, which is a dipeptide that reduces lactic acid buildup in the muscles and may lower muscle fatigue. (2)
L-citrulline: An amino acid that promotes nitric oxide production, and may improve blood flow and muscle function during a workout. (1)
Creatine: A naturally occuring amino acid that supports muscle energy production and may improve exercise intensity and performance. (46)
Betaine: A naturally occurring chemical that may increase creatine production and blood nitric oxide levels to aid in exercise performance. (46)
The supplements may also contain amino acids like taurine for support endurance and branch-chain amino acids (BCAAs) to aid in muscle protein synthesis. (46) However, the scientific evidence that amino acids in pre-workout supplements offer any ergogenic benefits is limited. (46)
Available in 12 flavors, Transparent Labs BULK contains no artificial colors, flavors, or sweeteners. It does, however, contain clinically-dosed ingredients, including nootropics for improved mood and focus.
Our product tester appreciated how BULK provided sustained energy without any crashes.
At $1.67 per serving, our top overall pre-workout is priced slightly above the market average.
Transparent Labs created this pre-workout for active individuals who want clinical doses of key ingredients that support enhanced mood and performance.
Slightly above the average price for this category at $1.67 per serving
Why we like Transparent Labs BULK as best pre-workout overall
Transparent Labs is known for producing high-quality supplements, including one of our favorite protein powders. With 200 milligrams of caffeine, their BULK pre-workout is designed to provide energy, endurance, and pumps. It’s a third-party tested, high-quality formula made without artificial dyes, sweeteners, or flavors.
BULK contains 8 grams of citrulline malate. Citrulline malate helps boost nitric oxide production for improved blood flow and enhanced nutrient and oxygen supply to muscles. It may also improve muscular endurance and athletic performance during a workout. (1)
Also included in clinically studied dosages are 4 grams of beta-alanine and 2.5 grams of BetaPure betaine anhydrous. (2,3) Beta-alanine helps increase muscle carnosine levels, which buffers lactic acid build-up in the muscles and potentially reduces muscle fatigue. (2) Betaine anhydrous may help you increase total reps and volume load during a weightlifting session. (4)
Beyond its physical benefits, BULK incorporates nootropics to help promote the right mood and focus for the workout. L-tyrosine is an amino acid that can be converted to dopamine, which is a key brain neurotransmitter linked to stress management, motivation, and mental focus. (5)
Furthermore, the ingredient alpha-GPC, a bioavailable source of choline, is recognized for its potential to elevate cognitive function, including memory, learning, and focus, especially when taken with caffeine. (6)
Our expert product tester, a certified personal trainer, tried the blue raspberry flavor. He rated the taste a solid 5 out of 5 stars.
“The blue raspberry flavor tastes exactly like how it sounds. It’s not too sweet, which I think is a good thing.”
Team Product Tester
Moreover, the pre-workout powder mixed extremely well without any clumps, earning solubility a perfect score of 5 out of 5 stars.
Our tester experienced the full effects of BULK. He noticed increased focus during his workout without feeling too wired. He also didn’t experience any energy crashes once the caffeine wore off.
With a cost of $1.67 per serving, this product is priced higher than several other pre-workouts we recommend, placing it slightly above the average cost in this category. However, when you consider the potent formulation, nootropics, and third-party testing through Informed Choice—assuring that it is free of banned substances—it could be worth it.
On Amazon, reviewers appreciate the clinically effective doses of ingredients and the immediate effects of Transparent Labs BULK.
“Performance wise the best I’ve ever experienced. Unparalleled focus and drive using this pre-workout. Highly recommended,” wrote verified customer Erik O.
A few customers were disappointed in some of the flavors and noticed an artificial taste despite the formula being all-natural.
“Decent product but like other people I have a hard time with the taste,” noted another verified buyer with the username “new customer.”
Legion Athletics Pulse is formulated with active men in mind, offering both caffeinated and non-caffeinated versions in 20 different flavors.
The caffeinated version of Legion Athletics Pulse contains 350 milligrams of caffeine, ideal for men who have higher energy needs and want to push their limits in the gym.
At $2.25 per serving, this pre-workout is expensive compared to the category average.
The range of flavors and stim-free options further enhances its appeal to men who are serious about clean, effective supplementation.
Twenty flavor options available in the caffeinated version
Third-party tested
Superior mixability
Cons
Well above the average price for this category at $2.25 per serving
Contains erythritol, which could be linked to blood clotting
Caffeinated version is not ideal for evening or nighttime workouts due to 350 milligrams of caffeine per serving
Why we like Legion Athletics Pulse as best for men
Legion Athletics Pulse, with its formulation, variety of flavors, and high caffeine content, is our number one choice for men since we believe it effectively addresses their performance and recovery needs.
For one, the 8 grams of citrulline malate in each serving not only improves endurance but also supports nitric oxide production—a key factor in muscle pump and vascularity, which are often a focus in men’s fitness goals. (1)
Additionally, men tend to benefit more from higher doses of ingredients like beta-alanine and betaine, both of which are included in Pulse at levels designed to maximize strength and power during high-intensity workouts. The supplement offers 3.6 grams of beta-alanine, 2.5 grams of betaine, and 300 milligrams of alpha-GPC in each serving. These ingredients are known to reduce exercise-induced fatigue, promote muscle strength, and boost power, making it the ideal choice for men who want to perform their best. (22)
If you’re reaching for the caffeinated version, expect 350 milligrams of caffeine—a solid jolt that’s perfect for powering through tough workouts. Just know it’s on the higher end, so if you’re sensitive to caffeine, the non-stim option might be your best bet.
The natural sweeteners in Legion Pulse—stevia and erythritol—provide a clean taste without the artificial additives. While there’s some debate about erythritol and blood clotting, the research isn’t conclusive, and the amount in this product is considered safe. (23)
Our expert tester, a certified personal trainer and Precision Nutrition certified nutrition coach, rated the taste 4 out of 5 stars.
At $2.25 per serving, Pulse is more expensive than other options on the market. That said, we believe the all-natural formula may be worth it for men looking to enhance their workout routine.
“I tried the Blue Raspberry flavor. It’s sweet, but I found it kind of bitter. I also noticed a weird aftertaste.”
Team Product Tester
Importantly, the product’s solubility was rated 5 out of 5 stars, ensuring a smooth mix without any grit—perfect for men who want a simple, effective pre-workout.
Another one of our team’s testers felt energized but not jittery—a nice balance that makes Pulse a go-to for men who want to feel powerful without overdoing it.
Reviews on Amazon for Legion Athletics Pulse are generally positive. Buyers appreciate the clean ingredients and the pump they feel after taking it.
“The supplements or other ingredients that are in this pre-workout are phenomenal and I would highly recommend getting this,” said verified customer Anthony.
Reviews are mixed on the taste, however. Some flavors appear to taste great while others taste bitter or leave a weird aftertaste.
Verified buyer Erik Baker II wrote, “Great price, gives you an energy boost without the jitters or cramping…great flavors as well! Love the blood orange, pink lemonade, and watermelon.”
Verified customer Diane Ray said, “I got the green apple flavor, and I can’t say it’s bad, but it’s definitely not the tastiest pre that I’ve tried. The flavor is good, but there’s also a bitterness to it, especially on the last swig.”
Nutricost Pre-X Xtreme offers a potent blend of caffeine, nootropics, and performance-enhancing ingredients for improved energy and focus. While some key ingredients are underdosed, the supplement’s affordability and third-party testing still make it a top choice.
The combination of L-citrulline malate and Nitrosigine boost nitric oxide and increase blood flow to the muscles to improve exercise performance.
At $1.10 per serving, our top high-stim pre-workout is priced below the market average.
Made with gluten-free, non-GMO, and vegetarian ingredients, Pre-X is a great option for vegans and health-conscious users.
Citrulline malate, beta-alanine, and betaine anhydrous are underdosed
Why we like Nutricost Pre-X Xtreme as best high-stim pre-workout
Designed to provide energy and focus, Nutricost Pre-X Xtreme is third-party-tested, boasts a high-quality formula, and contains gluten-free and non-GMO ingredients. One serving offers 300 milligrams of caffeine, making it ideal for users with a high caffeine tolerance who need a stronger pre-workout.
In addition to the performance-enhancing ingredients, Nutricost Pre-X Xtreme incorporates nootropics like L-tyrosine, alpha-GPC, DMAE bitartrate, CDP choline, and huperzine A to enhance cognitive performance and focus.
Each serving includes 250 milligrams of N-acetyl L-tyrosine, an amino acid and precursor to neurotransmitters such as dopamine and epinephrine. L-tyrosine may enhance cognitive performance, especially in short-term stressful or mentally demanding situations. Alpha-GPC is a choline-containing compound that may improve cognitive function, including memory and focus, especially when paired with caffeine. (42)(6)
The citrulline in this formula helps improve blood flow and enhances nutrient and oxygen supply to muscles. However, Pre-X Xtreme only contains 4 grams of L-citrulline malate, which is below the clinical dose of 6 to 8 grams. This pre-workout also contains a clinical dose of Nitrosigine (a complex made of arginine, inositol, and potassium silicate), which increases blood flow to working muscles through vasodilation. The combination of these ingredients may improve athletic performance. (1) (41)
There are also 2 grams of beta-alanine and 1.5 grams of betaine anhydrous per serving. Beta-alanine may reduce muscle fatigue, while betaine may help you perform more reps and volume during a weightlifting session. However, both of these ingredients are underdosed. The clinical dose for beta-alanine is 4 to 6 grams. A clinically effective dosage of betaine anhydrous is 2.5 grams. (2)(3)(4)
With a cost of $1.10 per serving, this product is one of the most affordable pre-workouts we recommend, placing it well below the average cost in this category. When you consider the potent caffeine content, nootropics, and third-party testing, Nutricost provides a lot of value for your money.
One verified buyer on Amazon named Joe said he loves this pre-workout and gets an excellent pump even though he only takes half a serving.
“Love this stuff. It really gets me going in the gym, today I hit a deadlift PR after taking this. I only take half a scoop because I have a pretty low caffeine tolerance, but this still really gets you going,” he wrote. “The pump, the body feel, the tingling from the beta alanine, you get a really high quality workout after taking this because it just gets your blood flowing. I’m amazed that it costs so little considering you get everything you want from a preworkout mix out of this.”
However, Joe said he wasn’t a huge fan of the blue raspberry flavor.
“My one complaint was the flavor: I got the blue raspberry stuff and MAN is that a strong flavor. I usually dry-scoop my preworkout but even when you dilute it with a ton of water it still has a very strong sour taste,” he commented. “My friends seemed to like the taste after I gave them a scoop but after having taken it a few times I think it’s way too strong. Still, I know I’ll be purchasing this product again because it’s such a fantastic value. Anyways, this stuff is fantastic for me during weightlifting, and I would 100% recommend it as someone who’s tried a lot of different mixes that try to get what this preworkout offers.”
Gainful Pre-Workout is available caffeinated, non-caffeinated, with creatine, or without creatine so you can customize it based on your supplement needs and caffeine preference.
The High Intensity + Creatine option is ideal for runners because it contains 200 milligrams of caffeine, 5 grams of creatine, and BCAAs. Together, these ingredients can help increase runners’ energy levels and improve muscle recovery.
At $1.86 per serving, Gainful pre-workout is slightly above the market average price.
That said, the addition of creatine and BCAAs replaces the need to buy multiple supplements, making it more cost-effective.
Beta-alanine and citrulline malate doses aren’t clinically effective
Why we like Gainful Pre-workout as best pre-workout for running
Gainful offers a unique opportunity to customize your pre-workout’s caffeine and creatine content based on your exercise intensity. Whether you need an energy boost for a long outdoor run or a quick interval workout on one of the best treadmills, you may be particularly interested in the High-Intensity + Creatine option. It contains 5 grams of creatine, 4 grams of L-citrulline DL-malate, 1.5 grams of beta alanine, 200 milligrams of caffeine, 330 milligrams of L-theanine, BCAAs, and 2.5 grams of leucine. Combined, these ingredients can enhance high-intensity exercise performance and maximize endurance and recovery time.
The Moderate Intensity + Creatine option contains 4 grams of L-citrulline DL-malate, 3 grams of creatine, 1.5 grams of beta alanine, 150 milligrams of caffeine, 250 milligrams of L-theanine, and 2 grams of BCAAs total.
The Moderate Intensity option contains 4 grams of L-citrulline DL-malate, 1.5 grams of beta alanine, 150 milligrams of caffeine, 250 milligrams of L-theanine, and 2 grams of BCAAs total. It does not contain creatine.
There is also one non-caffeinated option (Moderate Intensity + Creatine) that contains 4 grams of L-citrulline DL-malate, 3 grams of creatine, 1.5 grams of beta alanine, and 2 grams of BCAAs total.
Each formula contains 4 grams of L-citrulline DL-malate, which falls short of the clinically recommended dosage for exercise performance (6 to 8 grams). The purpose of citrulline is to boost nitric oxide production, which enhances blood flow and nutrient delivery to muscles. (21)
Leucine, isoleucine, and valine, the three branched-chain amino acids (BCAAs), are important for muscle growth and repair. Leucine, in particular, plays a key role in muscle protein synthesis. Creatine monohydrate is one of the most well-researched supplements and is well-known for its positive effect on high-intensity exercise performance. In addition to caffeine, Gainful Pre-Workout also contains L-theanine to help increase energy, improve mood and cognitive function, and reduce stress and anxiety. (35)(36)(24)
Althought it’s priced above market average at $1.86 per serving, Gainful Pre-Workout contains BCAAs and creatine, replacing the need for a large supplement stack.
Available in nine flavors, Transparent Labs LEAN not only contains several ingredients with potential fat-burning benefits, but it also includes a clinically-dosed amount of citrulline malate for better pumps.
LEAN contains a fat-burning complex that includes acetyl-L-carnitine, chromium picolinate, and zinc.
Unlike many brands, Transparent Labs offers a full refund within 30 days if you don’t like the product.
You can utilize LEAN to fuel your training sessions as you work on shedding extra pounds while retaining lean muscle.
Contains ingredients that may enhance fat burning, such as acetyl-L-carnitine, chromium picolinate, and zinc
No artificial flavors, dyes, or sweeteners
Full refunds available within 30 days if you don’t like it
Cons
We noticed some “floaties” remained after mixing
Two grams of beta-alanine is lower than the recommended 4 to 6 grams per day
Why we like Transparent Labs LEAN as best pre-workout for weight loss
Transparent Labs LEAN is made to target fat loss while simultaneously preserving lean muscle mass. It includes the most common pre-workout ingredients for improved energy and power, such as citrulline malate and caffeine, plus a fat-burning complex that may help you shed stubborn body weight with regular exercise.
Each serving contains acetyl-L-carnitine, chromium picolinate, and zinc, which may help with metabolism and support fat utilization. L-carnitine helps move fatty acids into your cells’ mitochondria to be converted into cellular energy, also known as ATP. (27) Some research shows L-carnitine may help reduce body fat, body mass index, and weight. (28)
Chromium picolinate is a form of the mineral chromium that may help manage blood sugar and cravings, as well as optimize metabolism. (29) However, studies show minimal weight loss during chromium supplementation. (30)
Finally, zinc may help control appetite and reduce weight in individuals at an unhealthy weight. (31)
This product still contains the usual pre-workout ingredients like citrulline malate, beta-alanine, and betaine anhydrous, which may improve vasodilation (widening of the blood vessels), endurance, and energy for a well-executed workout session. It also includes 180 milligrams of caffeine to reduce fatigue. However, the 2-gram dose of beta-alanine is lower than the recommended 4 to 6 grams daily. (2)
You have nine flavor options, providing plenty of opportunities to mix things up. Our tester enjoyed the taste of LEAN and rated it 5 out of 5 stars. However, she rated solubility 4 stars.
“It wasn’t too sweet and was just a tad bitter,” she says. “I noticed some floaties in my shaker bottle once it was mixed, but it was still drinkable. I didn’t experience any jitters after drinking a full serving size.”
On Amazon, the pre-workout earned high marks for its clean formula and transparent nutrition label.
“The things I appreciate the most are the transparency and quality of the ingredients,” verified buyer James wrote. “I use this nightly heading to the gym. Although I haven’t experienced any big boost of energy, the ingredients keep me committed to using it.”
Some Amazon customers enjoyed the flavors while others said they wouldn’t order this pre-workout again. “The product tastes terrible, like a super artificial peach…won’t be buying again,” said verified buyer Johanna T.
Jacked Factory Nitrosurge is a low-caffeine, low-cost pre-workout that should allow new lifters to get used to the feeling of fueling up before a training session.
Our product tester rated the formulation 4 out of 5 stars, noting that it contains performance-boosting ingredients like L-citrulline and L-theanine.
Nitrosurge only costs $1 per serving if using one scoop, making it among the most inexpensive pre-workouts in this category.
With a moderate amount of caffeine and a low price tag, Nitrosurge works well for beginners who want to test their tolerance without making a significant investment.
Budget-friendly price well below the category average at only $1.00 per scoop
Vegan
Cons
Not third-party tested
Contains artificial sweeteners, which may cause gas and bloating in some individuals
Includes a few underdosed ingredients (such as 1.25 grams of betaine anhydrous, versus the recommended 2.5 grams)
Why we like Jacked Factory Nitrosurge as best pre-workout on a budget
At just $1.00 per serving (for one scoop), Jacked Factory Nitrosurge provides an affordable option for beginners interested in testing their tolerance to the typical pre-workout ingredients. The label includes nutrition information for a single-scoop or double-scoop serving, depending on your desired intensity.
The formulation, which our product tester rated 4 out of 5 stars, contains several workout-enhancing ingredients. For example, one scoop offers 3 grams of L-citrulline, a non-essential amino acid that may heighten nitric oxide production and support more efficient blood flow to the muscles, potentially giving you a performance advantage to get in extra reps. (7)
However, some ingredients are underdosed. The beta-alanine content of 1.6 grams per scoop falls below the 4- to 6-gram daily recommended dosage suggested by the International Society of Sports Nutrition for certain exercises but lessens the likelihood of experiencing the common side effect of paraesthesia (tingling). (2) Beta-alanine has the potential to decrease muscle fatigue and extend the duration of exercise before reaching exhaustion. (2)
Similarly, the 1.25 grams of betaine anhydrous in a scoop of Nitrosurge doesn’t meet the clinically studied dose of 2.5 grams shown to improve exercise performance. (3) If you take the double scoop, you meet that threshold. Betaine anhydrous may positively influence body composition, muscle growth, and work capacity.
Theobromine and L-theanine work together to sharpen mental focus, diminish susceptibility to distractions, and reduce stress, promoting a more accomplished workout. (24) AstraGin is a patented ingredient incorporated to help your body better absorb the key nutrients within the formulation.
Nitrosurge is sweetened with sucralose and Ace-K, two artificial, zero-calorie sweeteners. Our tester tried the Strawberry Margarita flavor (only available on Amazon) and rated the taste 5 out of 5 stars.
Editorial team member Kate Meier, a certified personal trainer and competitive Olympic weightlifter, said, “I could sip on the Strawberry Margarita Nitrosurge all day while laying out by the pool.”
Kate also rated solubility 5 out of 5 stars. She used a shaker cup to mix Nitrosurge with water and experienced no trouble dissolving the product. She didn’t feel any tingles or itching, a common side effect of pre-workouts with beta-alanine, but noticed a sense of heightened energy.
Jacked Factory Nitrosurge appears to be a popular pre-workout choice on Amazon. Customers say they enjoy the range of flavors and don’t experience too many facial tingles.
“I really like this pre-workout and have tried it in multiple flavors but the blue raspberry is my favorite,” verified customer Catherine Charbonneau wrote. “Sour peach rings is also tasty.”
A few Amazon reviewers stated they didn’t feel any effects, but most buyers say they start feeling it pretty quickly. Nitrosurge helps them remain energized, even for workouts that last more than two hours.
“The pump/effects didn’t last long. Not the worst but won’t be buying again,” commented verified buyer Joshua Langel.

Onnit Alpha BRAIN includes typical pre-workout ingredients like beta-alanine, L-citrulline, and caffeine, plus ashwagandha for improved mood and reduced stress.
Alpha BRAIN contains a trademarked form of ashwagandha extract—an adaptogen that may help relieve stress and anxiety.
At $3.00 per serving, this focus-enhancing pre-workout is one of the most expensive in this category.
Onnit Alpha BRAIN supports mental focus and physical energy, which makes it a great choice if
Includes nootropics for improved focus and mental clarity
Tester-approved Tiger’s Blood flavor
No artificial colors, sweeteners, or flavors
Cons
2.4 grams of L-citrulline is below the clinically recommended minimum of 3 grams
The Yuzi Peach flavor wasn’t favored by our testers
Expensive for this category at $3.00 per serving
Why we like Onnit Alpha BRAIN as best pre-workout for focus
Onnit Alpha BRAIN pre-workout is formulated with key ingredients that support mental focus and physical energy so you can make the most of every training session. It also contains fundamental pre-workout ingredients, including beta-alanine, L-citrulline, and caffeine, to increase energy levels, alertness, strength, and endurance.
The L-citrulline dosage, at 2.4 grams, falls below the clinically recommended range of 3 to 6 grams. (7) In a study involving cyclists, those who consumed a daily dosage of only 2.4 grams of L-citrulline for eight days could cycle faster and longer than the placebo group before experiencing fatigue. (8)
Onnit Alpha BRAIN provides 200 milligrams of caffeine and 50 grams of Dynamine in each serving. Dynamine is a trademarked ingredient that may help improve working memory, cognitive control, and reaction time when taken with caffeine. (9) Together, these two ingredients could enhance cognitive performance during mentally demanding tasks.
For even more cognitive benefits, each serving provides 225 milligrams of Nooghanda, a trademarked form of ashwagandha extract. Ashwagandha is an adaptogen that may help relieve stress and anxiety and improve memory and mood. (10) Some research even suggests ashwagandha could improve physical strength and power. (11)
Your two flavor choices include Tiger’s Blood and Yuzu Peach. Alpha BRAIN utilizes natural sweeteners and never contains artificial colors or flavors.
Two of our expert testers, who are competitive Olympic weightlifters and certified weightlifting coaches, tried both flavors. They rated the taste 4 out of 5 stars. Of the two flavors, they preferred Tiger’s Blood.
“Tiger’s Blood has a tropical taste, but doesn’t have a lot of pineapple like you’d expect in a tropical drink. Instead, there are hints of coconut, watermelon, and strawberry.”
Team Product Tester
The Yuzu Peach flavor had a slightly bitter taste that our testers found off-putting. However, they rated solubility 5 out of 5 stars and had no trouble mixing the powder.
Our testers also had other weightlifters at their gym try Onnit Alpha BRAIN. The consensus was clear: it enhanced their focus and clarity during workouts. They didn’t find it overly stimulating like other pre-workouts with a higher caffeine content. Rather, it helped them feel present and ready to do the work.
Our team didn’t experience any beta-alanine tingles or itching from this one, but some still got a good pump. Overall, they had a positive experience and rated the effects 4 out of 5 stars.

What customers are saying
Reviews on Amazon are mixed. Positive reviews mention increased energy and concentration in the gym as noteworthy features.
One anonymous verified buyer on Amazon wrote, “The focus is better with this pre-workout thanks to the nootropic blend and the energy is definitely there. It’s pricey but…it’s worth a try for sure.”
Other reviewers say this pre-workout tastes bitter. Another anonymous verified customer also said the supplement “doesn’t mix well at all. Product sticks to shaker cup and doesn’t break down like it should.”
Why we like Promix Pre-Workout as best vegan pre-workout
Pre-workout supplements generally don’t contain animal products, but Promix is our favorite vegan option. It contains all-natural ingredients and is free of gluten, dairy, soy, and GMOs. With 200 miligrams of caffeine, 3.2 grams of beta-alanine, 3 grams of L-tyrosine and 1 gram of taurine, it can improve endurance exercise and help boost energy, cognitive function, and focus.
Caffeine can help improve cognitive function, including reaction time, memory, and attention. In terms of exercise performance, caffeine can improve aerobic and anaerobic exercise, and has a positive effect on endurance, sprint speed, and muscle power. Taurine is an amino acid that may benefit athletic performance. However, it’s usually combined with caffeine or other ingredients in studies, so it’s unclear if those benefits are directly related to taurine. (43)(44)
Beta-alanine is most beneficial for high-intensity exercises lasting 1 to 10 minutes. This includes running, swimming, and heavy weightlifting. Some studies show a range of 3.2 to 6.4 grams of beta-alanine taken daily is effective for enhancing exercise performance, but others suggest a range of 4 to 6 grams might be more ideal. (45)
This formula also contains 3 grams of L-tyrosine to improve focus and cognition. L-tyrosine is especially beneficial under short-term stressful or cognitively demanding conditions. (42)
If you’d prefer a pre-workout without caffeine, there is a stim-free option in the raspberry lemon flavor. There is also a tingle-free formula that doesn’t contain beta-alanine.
At $1.07 per serving, Promix Pre-Workout is the most affordable option we featured. However, it contains fewer key ingredients than other pre-workouts on the market, like L-citrulline. Also, the beta-alanine isn’t a clinically effective dosage. But we do like that Promix is made in GMP-certified facilities and is third-party tested. The testing data is available on the Promix website.
What customers are saying
On Amazon, customers regularly leave positive reviews about the taste, clean ingredients, and packaging.
“I bought this for the clean ingredients- was a little afraid I’d have to sacrifice taste for the clean ingredients but the flavor is surprisingly good,” wrote one verified buyer named Lo. “I bought the strawberry lemon flavor. It’s not as sweet as other pre workouts because it doesn’t have all the added sugar like some do (& that was my goal to avoid), but I actually like the subtle sweetness from the monk fruit better.”
A verified Amazon customer named Annie also liked the light flavor and use of natural sweeteners.
“Every other pre workout I’ve tried tastes terribly overly flavored and sweetened with artificial sweeteners. This is only one with the ingredients I was looking for that didn’t have all kinds of excess sweetness and flavor. Plus the packaging is not a big plastic tub and scooper. Thoughtfully done.“
Verified Amazon Customer
However, some customers said they felt sick or experienced nausea after taking Promix Pre-Workout. “I took this pre-workout and after about 45 minutes I experienced extreme nausea. It took about 3 hours to fully get out of my system,” noted verified buyer Kait. “I have taken pre-workouts in the past and I regularly drink caffeine so I am not sure why I reacted the way I did.”
Optimum Nutrition Gold Standard Pre-Workout may not have a high amount of caffeine, but it does feature 3 grams of creatine per serving. Plus, it’s well-priced and earns high marks for taste.
Optimum Nutrition formulated this pre-workout with a clinically dosed 3 grams of creatine, which can help support strength and muscle gains.
At $1.10 per serving, Gold Standard Pre-Workout is among the most affordable supplements in this category.
With only 175 grams of caffeine per serving, this pre-workout will provide an energy boost without increasing your heart rate significantly.
Affordable price below average at $1.10 per serving
May enhance muscle strength and growth
Includes B vitamins for energy
Includes 3 grams of creatine, while many other pre-workout supplements only have two
Cons
Underdosed ingredients (for example, the 1.5 grams of beta-alanine is lower than the recommended dose of at least 4 grams per day)
Includes artificial dyes, sweeteners, and flavors
Some flavors tend to sell out quickly
Why we like Optimum Nutrition Gold Standard Pre-Workout as best pre-workout for beginners
Optimum Nutrition Gold Standard Pre-Workout blends caffeine, creatine monohydrate, and beta-alanine to increase energy, enhance focus, and improve endurance. The dosages are suitable for beginners who want to ease into pre-workout supplements or for individuals who prefer milder effects than full doses of pre-workout ingredients.
Unlike many pre-workout supplements, this one contains a clinically dosed 3 grams of creatine, a chemical found naturally in the body that helps produce energy in muscle. When supplemented, creatine monohydrate may increase strength and muscle gains when combined with regular resistance training. (32)
Furthermore, 1.5 grams of beta-alanine may help buffer the accumulation of lactic acid buildup, possibly improving muscular endurance and allowing you to exercise longer before feeling fatigued. (2) Although this dose is lower than the recommended 4 to 6 grams daily, it may be preferred by beginners who want to assess tolerance or reduce the feeling of skin tingling caused by beta-alanine.
The 175 grams of caffeine is plenty to give a push of energy and focus but likely won’t trigger uncomfortable side effects of higher doses, such as rapid heart rate or anxiety. Additionally, L-carnitine plays a critical role in fat metabolism and may support weight loss. Some research shows it could help reduce body weight and fat mass in adults at an unhealthy weight. (33)
Finally, the product offers several vitamins that support energy. B vitamins, including vitamin B12, niacin, folate, pantothenic acid, and thiamine, are essential for energy metabolism. These vitamins help convert carbohydrates, fats, and proteins to energy that can be used during physical exercise. (34) While Gold Standard Pre-Workout won’t necessarily eliminate the need for a high-quality multivitamin, the inclusion of several essential vitamins is a nice touch.
Some of our product testers have used Optimum Nutrition Gold Standard Pre-Workout for years. They rate the taste 5 out of 5 stars, claiming the flavors are always delicious and just the right amount of sweet. They also love the product’s solubility, giving it 5 out of 5 stars. It easily mixes in a mixer cup without any floaties or clumps.
“I feel focused and energized when I take Gold Standard Pre-Workout. It doesn’t provide the greatest pump, but it’s always a reliable choice for a pre-workout.”

What customers are saying
Customers on Amazon praise this pre-workout’s solubility and great-tasting flavors. They like that it contains creatine so they don’t have to spend money on another supplement.
“I love this pre-workout. Having the creatine mixed in is awesome and I love the taste,” wrote verified buyer Don Kitchen.
However, several Amazon reviewers claim it doesn’t give them the same amount of energy as other pre-workouts, even ones that have a similar amount of caffeine (175 milligrams per serving).
“This will certainly help you get moving, but it does not really help you focus nor does it give you a surge of energy,” verified customer Chris wrote in their review.
With 300 milligrams of caffeine per serving, PRE JYM should provide sufficient energy to power through your workouts. This pre-workout will also support your muscle-building journey via BCAAs, creatine, and other ingredients.
PRE JYM stands out from its competitors by including BCAAs and creatine—both of which play important roles in muscle growth and repair.
This pre-workout costs $1.83 per serving, putting it above the average cost for this category.
Not only does PRE JYM taste great, but it contains 13 active ingredients that can enhance your performance and help you build lean muscle.
Delicious taste according to the Fortune Recommends product testers
May enhance muscle strength and growth
Includes nootropics for focus and motivation
Dissolves completely in a shaker bottle
Cons
Underdosed creatine HCL of 2 grams per serving (the clinically effective dose is 3 to 5 grams)
Not for evening or late night workouts before bed due to the 300 milligrams of caffeine
Includes artificial dyes, sweeteners, and flavors
Slightly above average cost in this category at $1.83 per serving
Why we like PRE JYM as best-tasting pre-workout
PRE JYM is one of our team’s favorite pre-workouts for its effectiveness and delicious taste. Coming from product testers who’ve tried over 50 pre-workouts, that says a lot. PRE JYM contains just the right sweetness with no bitter or artificial aftertaste.
JYM pre-workout contains 14 active ingredients that have been studied for their potential to enhance exercise and build muscle.
The key ingredients in JYM pre-workout include 6 grams of citrulline malate, 6 grams of branched-chain amino acids (BCAAs), 2 grams of creatine, and 2 grams of beta-alanine. The BCAAs and creatine immediately make this product stand out from others that don’t include these ingredients.
BCAAs are essential for muscle growth and repair. Leucine is an essential BCAA that creates new proteins in muscle cells, which is necessary for visible gains. (35)
Regarding muscle gains, PRE JYM contains creatine, which could enhance muscle strength and growth. (32) However, this product’s 2 grams of creatine hydrochloride (HCl) don’t meet the clinically studied dose of 3 to 5 grams. (36)
Furthermore, while the body may more readily absorb creatine HCl, extensive research does not support its effectiveness in enhancing exercise performance or promoting muscle mass growth compared to creatine monohydrate.
PRE JYM contains several nitric oxide boosters and beetroot extract. These ingredients are vasodilators that improve blood flow to the muscles, which could result in greater muscle pumps. (37) It also contains betaine anhydrous, which can support strength during training and more desirable body composition. (40)
Moreover, the product includes alpha-GPC, a nootropic that can help with mental focus and heightened motivation. (38) As if that wasn’t enough, each serving boasts 300 milligrams of caffeine. If you’re sensitive to stimulants like caffeine, consider starting with half a scoop to see how you feel.
Two of our product testers tried the Rainbow Sherbet and Pineapple Strawberry flavors, and they rated the taste 4.5 out of 5 stars. “If it didn’t have so much caffeine, I would drink the Pineapple Strawberry flavor while sitting on a beach,” one of our testers commented.
Another reviewer, a USA Weightlifting Level 2 coach, noted that the Rainbow Sherbet flavor was delicious and sweet.
Both product testers rated solubility 5 out of 5 stars. They experienced no issues mixing it in a shaker bottle.
What customers are saying
Satisfied customers on Amazon say PRE JYM doesn’t give them a rapid heartbeat like other pre-workout formulas. Instead, it offers a steady source of energy and results in good pumps that last even when their workouts are done.
“This product gives me the pump I need for my workouts without the jitters that other pre-workouts give,” verified customer Anthony Ellenwood wrote.
Overall, Amazon buyers are pleased with the flavors, especially Rainbow Sherbert, Pineapple Strawberry, and Grape Candy. However, some say this pre-workout is too sweet for their liking. Others say they notice an artificial taste.
“Doesn’t taste like it says,” commented verified buyer Gary Mayes. “Not really impressed with it.”
Every pre-workout supplement we review is rated across nine primary categories. Each category is assigned a different percentage weight of the total score based on its relative importance when considering whether or not you should purchase a pre-workout product. Pre-workout supplements can also earn bonus credits that boost the overall rating for third-party testing credentials, sustainable packaging, the addition of antioxidants, and more.
Common stimulant sources of energy in pre-workout supplements are caffeine anhydrous, PurCaf, di-caffeine malate, and theobromine. Common stimulant-free ingredients that support energy include taurine, eleuthero root, niacin, and vitamins B6 and B12. We look for effective doses of these ingredients for energy.
Ingredients for endurance—10%
When included in effective doses, some pre-workout formula ingredients may boost mental and physical endurance during workouts. These include beta-alanine, Carnosyn, ancient peat, and apple extract, Rhodiola rosea, L-carnitine, eleuthero root, astragalus root extract, Astragin, and Senactiv. We look for effective doses of these ingredients for endurance.
Ingredients for lean muscle support—10%
We look for 11 ingredients in effective doses that support lean muscle growth. Some of these ingredients are backed by more research than others, and they are weighted accordingly in the score for this section. The ingredients are creatine, betaine, leucine, taurine, isoleucine, valine, zinc, vitamin B, BCAAs, boron, and calcium.
Ingredients for muscle fatigue reduction—10%
We look for pre-workout formulas with ingredients shown to reduce muscle fatigue. Specifically, we look for formulas that include citrulline malate and beetroot.
Non-stim ingredients—10%
Non-stimulant ingredients, such as vitamin B12, B6, or Taurine, are important because they support energy production and overall performance without relying on stimulants like caffeine. Including non-stim ingredients ensures that the supplement provides a more balanced and sustained energy boost, reducing the risk of jitters or crashes that can come with high-stimulant products. This makes it a valuable consideration for those seeking a more natural or less intense energy boost from their pre-workout supplement.
Ingredients for focus—5%
Improved focus can add to the intensity and intentionality of your workout. Many ingredients in pre-workout formulas included for focus either aren’t backed by studies or the studies show no effect. Still, we consider the inclusion and dosing of four common pre-workout ingredients in this category, though with a much smaller weight in the overall score. They include Alpha GPC, tyrosine, huperzine A, and choline bitartrate.
Ingredients for hydration—5%
Hydration plays an important role in muscle performance and recovery. We give high scores in this category to formulas that contain sodium, potassium, and/or coconut water powder (a natural source of potassium).
Sweeteners—10%
We consider research about common sweeteners when assessing which pre-workout formulas provide the least health risks to users.
Cost per serving—5%
While price isn’t always indicative of quality or value, we do reward more affordable pre-workout supplements, though we give this category less weight than the others.
Benefits of pre-workout
Incorporating pre-workout before exercise has the potential to improve athletic performance, boost energy levels, and heighten focus. Here’s a look at how these supplements could help to maximize your workouts:
Increased energy: Pre-workout ingredients like caffeine may temporarily diminish fatigue and elevate energy levels.
Improved endurance: Pre-workout supplements commonly include ingredients that could enhance endurance, delay the onset of fatigue, and reduce perceived exertion during physical activity.
Enhanced focus: Formulas containing caffeine, L-tyrosine, and L-theanine have the potential to enhance mental focus, alertness, mood, and overall cognition.
Improved blood flow: Ingredients like citrulline promote nitric oxide production, enhancing blood flow and increasing the delivery of oxygen and nutrients to the muscles.
Increased strength: Pre-workout supplements with creatine or citrulline may increase strength and power output during exercise.
What to look for in pre-workout
Look for pre-workouts with research-backed ingredients in clinically effective dosages. These could include:
3 to 6 grams of L-citrulline (or 6 to 8 grams of citrulline malate)
4 to 6 grams of beta-alanine
2.5 grams of betaine anhydrous
Search for products that are third-party tested to ensure quality and safety. The Food and Drug Administration (FDA) doesn’t regulate supplements. Third-party testing helps to ensure that pre-workouts don’t contain potentially harmful levels of heavy metals or other contaminants.
Check out customer reviews on the product website to gather insights into taste and solubility. Explore opinions on specific flavors, the product’s texture, and overall user experience.
Finally, take into account the cost per serving when deciding on the ideal pre-workout. The pricing of a supplement can be deceptive, so it’s crucial to account for the number of servings per container. Select a supplement that fits within your budget, ensuring a convenient option for repeat orders.
When is the best time to take pre-workout?
The best time to take pre-workout is typically 20-60 minutes before you start exercising. This timing allows the ingredients, particulalry stimulants like caffeine, to be absorbed and start working by the time you hit the gym. (46) However, the optimal timing can vary based on your schedule and personal preferences.
If you work out in the morning, a pre-workout can help you shake off any grogginess and give you a burst of energy to kickstart your day. For those who prefer afternoon workouts, a pre-workout can help combat the midday slump and provide the focus needed to push through. However, if you exercise in the evening, you should be cautious with pre-workouts that contain caffeine or other stimulants, as taking them too late can interfere with your sleep. It’s generally advised to avoid taking a caffeinated pre-workout within 4-6 hours of bedtime. If you prefer working out at night, consider using a stimulant-free pre-workout to avoid any potential sleep disruptions.
Additionally, consider your meal timing when planning to take a pre-workout. If you’ve just eaten a large meal, it might be better to wait a little longer before taking your supplement to avoid digestive discomfort. Conversely, if you’re working out on an empty stomach, you may feel the effects of the pre-workout more quickly.
Taking your pre-workout at the right time can maximize its benefits, ensuring that you’re energized and focused throughout your workout.
Other pre-workouts we reviewed
We liked many of the pre-workout supplements we tested, but not all made our list of top choices. Some other options we liked include EBOOST’s POW Pre-Workout, Kaged’s Pre-Kaged Sport, and BPI Sport’s 1MR OG Pre-Workout Formula. While these options could be a good fit depending on your goal, a lack of third-party testing and general clinical dosages were the main issues we found.
FAQs
Which pre-workout gives the best pump?
We recommend Transparent Labs BULK for the best pump. BULK contains 8 grams of citrulline malate, a nitric oxide precursor that can improve muscle blood flow efficiency, which may give you a noticeable pump.
What is the most effective pre-workout?
We recommend PRE JYM for a pre-workout that delivers the best effects. PRE JYM contains 300 milligrams of caffeine, so you’ll likely feel energized and focused. It also includes nootropics for improved cognitive function and creatine and BCAAs for muscle building.
Are there healthy pre-workouts?
Consider pre-workouts made with natural ingredients, like Legion Athletics Pulse, when looking for healthy pre-workouts. Legion Athletics Pulse doesn’t contain any artificial sweeteners, dyes, or flavors. Also, consult your doctor before starting a pre-workout. You may need to avoid certain supplements depending on your medical conditions and prescribed medications.
Should I take pre-workout every day?
For many, it’s safe to take pre-workout daily as long as it contains safe amounts of each ingredient and isn’t contaminated with harmful amounts of heavy metals or other contaminants. Choosing a third-party tested product is the best way to ensure the safety of a supplement. If you have a medical condition or are taking prescription medications, check with your doctor before starting a new daily supplement.
Does pre-workout really help?
Preliminary evidence suggests that pre-workout does really help. (46) The supplement type may support muscle endurance and mood, but the effectiveness of a pre-workout depends on the ingredients used and dose. (46) Though promising, more research is needed to determine long-term efficacy and safety of pre-workout supplements.
What ingredients should you avoid in a pre-workout?
When choosing a pre-workout, you should avoid ingredients like excessive caffeine or artificial sweeteners, which can lead to jitteriness or digestive issues. (15) It’s also wise to steer clear of proprietary blends that hide the true dosages of ingredients. Instead, choose products with transparent labels and clinically supported ingredients for safer, more effective results.
Is pre-workout better than caffeine?
Currently, there’s not enough research to definitively say that pre-workout is better than caffeine. (46, 47) Numerous studies indicate that caffeine by itself supports exercise endurance, strength, and performance. (43) Though pre-workout also seems to support exercise, the variability of ingredients in formulas makes it difficult to determine if the benefits are due to the caffeine, the other ingredients, or both.
