The 8 best supplements for muscle growth, reviewed by a registered dietitian nutritionist

These days, building muscle isn’t just for athletes. Increasing stamina, coordination, balance, and preventing the loss of lean body mass with aging are goals shared by people from all walks of life, achieved through strength training. (1) Additionally, strength training creates what’s known as afterburn or excess post-exercise oxygen consumption (EPOC), which can last a few hours and reflects early recovery, while more comprehensive recovery and muscle adaptation is reflected in elevated calorie burning for a day or more. (2)

With the growing interest in muscle-building, supplements that aid in muscle growth have become increasingly popular. According to the National Institute of Health (NIH), past surveys show that 20% of supplement users specifically wanted to enhance muscle mass, while 19% aimed to increase performance. (3) These are significant numbers.

Supplements can be especially beneficial during intense workout phases, recovery periods after exertion, or for those who struggle to meet their nutritional needs through diet alone, providing an efficient way to support muscle growth and enhance overall performance. 

However, the marketplace is flooded with muscle growth supplements that may not be ideal for everyone. Because of this, our expert nutrition team combed through dozens of brands to find the top nine safest, most effective muscle growth supplements to help customers feel reassured and perform their best.

Editor’s choice: Transparent Labs BCAA Glutamine

Topping our list, Transparent Labs BCAA Glutamine is vegan-friendly and available in four tasty flavors without artificial sweeteners and colors. This dissolvable solution contains 8,000 milligrams of fermented branched-chain amino acids (BCAAs), 5,000 milligrams of glutamine, 1,500 milligrams of Vitamin C, and 1,000 milligrams of coconut water powder to not only support muscle development but also hydration and even help minimize delayed-onset muscle soreness (DOMS).

Why we like Transparent Labs BCAA Glutamine as best BCAA

When considering why this supplement stands out, it’s important to highlight its excellent formulation and the strong scientific evidence supporting its effectiveness. Unlike many other BCAA supplements on the market that rely on a one-size-fits-all approach, Transparent Labs BCAA combines high-quality, ethically-sourced ingredients tailored to enhance nutrient absorption. 

Specifically, one scoop of this powder delivers 8,000 milligrams of fermented BCAAs: leucine, isoleucine, and valine. These three essential amino acids must be obtained from food sources as our bodies can’t produce them. BCAAs are crucial for stimulating muscle growth, making this supplement a powerful aid for those looking to enhance their muscle development. (6)

However, branched-chain amino acids build muscle best when combined with other essential amino acids. (7) While glutamine is not an essential amino acid, Transparent Labs BCAA Glutamine contains 5,000 milligrams of glutamine per scoop, which can help maximize its properties as a building block in the formation of muscle protein in the body. (7) As glutamine helps BCAAs work at their maximum capacity, this supplement may also aid in the reduction of experiencing delayed-onset muscle soreness (DOMS), aka the muscle soreness you feel after 12-24 hours after an intense workout. (8)

Another factor that sets this supplement apart is its inclusion of 1,500 milligrams of vitamin C and 1,000 milligrams of coconut water powder per serving. While there isn’t sufficient data to support the use of these doses for muscle growth, it is a unique feature. Although vitamin C may be most known for its immunity benefits, it’s also an important nutrient for tissue healing due to its role in building collagen. (9) Additionally, coconut water powder (which, when mixed with water, creates drinkable coconut water) has been shown to potentially hydrate even better than plain water due to its inclusion of carbohydrates and electrolytes. (10) However, the product’s supplement facts does not list any electrolytes, which makes it difficult to confirm its hydration benefits.

Transparent Labs BCAA Glutamine comes in a powdered form that can be mixed with any beverage, including water, as this powder comes in four different flavors that are each sweetened with stevia, a natural zero-calorie sweetener that has no effect on blood glucose, making it suitable for those with diabetes. (5)

At $1.33 per serving, Transparent Labs BCAA Glutamine powder costs slightly less than other brands on our list which averages out to about $1.65 per serving. As a whole, muscle growth supplements do run more expensive than other supplement types on the market. However, you can save money by signing up for Transparent Labs’ subscription program where you can save $4 and earn free shipping while getting a fresh supply every 15, 30, or 45 days.

Another perk of Transparent Labs is, as their name suggests, their transparency. All of their supplements, including BCAA Glutamine powder, are third-party tested, and each bottle contains both a Certificate of Composition and a Certificate of Analysis. This is important, and while testing for safety is required, additional testing can help assure this product meets label claims

What you should know

Sports Research Whey Protein Isolate is a powder muscle growth supplement that can be taken by stirring it into water or made into a smoothie. It comes in two versatile flavors: chocolate and vanilla. One serving provides 25 grams of protein (derived from whey), and 6.9 grams of BCAAs (including 1,000 milligrams of L-leucine). Additionally, this powder contains 3 grams of MCT powder and 100% of the daily value for vitamin D3.

  • This whey protein powder can be had at any time of the day, and with plenty of protein, only 140-150 calories, and less than a gram of sugar per serving, it’s suitable for daily use whether or not you’re headed to the gym.
  • At $1.06-$1.42 per serving, Sports Research Whey Protein Isolate powder costs significantly less than our average muscle growth supplement cost of $1.65.
  • This protein powder contains 18 amino acids that are body protein building blocks, including 9 essential amino acids—those that our body is not able to produce on its own.
  • Sports Research Whey Protein Isolate powder contains an added 1,000 milligrams of L-leucine (in addition to naturally occurring levels) to ensure ample levels to help convert workouts to muscle growth and support recovery. (11)

Why we like Sports Research Whey Protein Isolate as best protein

Whey protein powder is one of the best supplements for muscle gain. Sports Research Whey Protein Isolate is our top pick for the best whey protein on the market as this blend contains ample amounts of 18 amino acids, nine of which are essential. In other words, they are known as essential because the human body is unable to make them naturally. Of these essential amino acids, this powder contains all three branch-chain amino acids (BCAAs): leucine, isoleucine, and valine. 

BCAAs are powerhouses when it comes to muscle formation and recovery, and leucine, specifically, not only builds muscle, but aids in enhanced cellular respiration, energy partitioning, and lean muscle gain. (11) Sports Research Whey Protein Isolate stands out as 1,000 milligrams of extra leucine have been added into this formula to help ensure optimal muscle recovery even on recovery or down days.

All BCAAs, however, only work at their maximum capacity if combined with other essential amino acids. (7) Whey protein is one of the most desired muscle growth supplements as it delivers a complete amino acid profile and is rapidly digested and absorbed, delivering amino acids to muscle faster than other proteins. 

Additionally, this whey protein blend includes 3 grams of MCT, or medium-chain triglycerides. MCTs are naturally found in dairy products and may hold several nutritional benefits including serving as an energy source and a potential aid in weight management. (12, 13) Sports Research Whey Protein Isolate powder also contains 100% of the daily value for vitamin D3. Vitamin D3, in combination with the natural calcium found in milk and resistance exercise, will positively impact bone density and skeletal health. (14

At $1.06-$1.42 per serving, Sports Research Whey Protein Isolate powder costs vastly less than other brands on our list which averages out to about $1.65 per serving. Whey protein is traditionally cheaper than other compounds as it is naturally derived from an accessible, ubiquitous ingredient—milk. Whey is the watery portion of separated milk, constituting about 20% of the total protein (therefore, this powder is not suitable for those with dairy allergies or who follow a vegan lifestyle). Subscriptions are also available that offer a 15% discount plus free shipping and planned delivery every 30, 60, or 90 days.

Sports Research Whey Protein Isolate has been third-party tested and approved by Informed Sport and also holds certifications from IGEN Non-GMO and Gluten Free. 

What customers are saying

Over 1,000 Amazon customers have reviewed Sports Research Whey Protein Isolate powder, and this muscle growth supplement has achieved 4.4/5 stars on the platform. Most reviewers say that the taste is great–not chalky, like other brands–and blends easily. Certain customers, however, did complain of stomach issues (probably attributable to a dairy intolerance). Others said that the mix was too sweet, which all comes down to personal preference.

“I have wasted so much money on protein shakes that I eagerly make and think this will be the one I can enjoy drinking…who’s with me on that one? I have finally found it with this one! No artificial taste, [and] I use a blender so no clumping issues.”

Username “Bella44,” verified Amazon customer

Other consumers note that this product had increased satiety, with one customer, Jose Ayala, noting that he found that his cholesterol lowered. “Not because of the product,” he says, “but the change I’ve done.” That is, mixing a protein shake for breakfast instead of indulging in a sugary, fatty meal that will leave him unsatisfied and lacking in the nutrition department.

Why we like Legion KSM-66 Ashwagandha as best ashwagandha

Although not traditionally considered a muscle growth supplement, ashwagandha can support several health outcomes that can help with gaining muscle mass. These benefits include reducing inflammation (aiding muscle recovery), enhancing athletic performance, and reducing fatigue. (56

Ashwagandha is an adaptogen, which means that it helps stabilize the body’s response to certain stressors without inducing an actual change in the body, such as increased oxygen consumption. (25) Although more research needs to be conducted on the efficacy of ashwagandha, certain studies do show that this herb may aid in the reduction of stress through controlling certain stress mediators in the brain. (26) Therefore, continued daily usage may lead to a gradual reduction of emotional overreaction in response to outside stressors. 

Research suggests that a typical dosage ranges from 300 to 600 mg of a standardized extract per day, commonly taken in two divided doses. (56) This supplement provides 600 mg, which is in the upper limit of a possible effective dosage.

When it comes to athletic performance–although mental health has a strong influence on physical health–preliminary studies show that ashwagandha may hold the potential to aid in athletic performance through increased muscle strength and power, cardiorespiratory fitness, and recovery. (27, 28) Ashwagandha may also aid in muscle recovery due to its support of normalizing inflammatory processes, as some inflammation can be important during training recovery. One 2021 study revealed a reduction in three separate inflammation markers as compared to those who were only given a placebo. (29)

Notably, Legion’s KSM-66 Ashwagandha supplement is on the cheaper end of our list, at just $0.50 per serving. Legion also offers a subscription package, where you can receive 10% off each order and receive refills every 30, 60, or 90 days. 

One of the best things about Legion is their transparency. Their ashwagandha is third-party tested in a ISO 17025-accredited laboratory and all facilities have been inspected by the FDA. In spite of the FDA’s lack of oversight, Legion’s Ashwagandha formula is NSF-certified and contains no proprietary blends and no heavy metals or allergens.

  • At $0.79 per serving, Gainful Creatine Monohydrate powder is much cheaper than our average supplement serving cost of $1.65.
  • Each serving (one scoop) contains 5 grams of creatine which can aid in both muscle gain and sports performance, making it a popular choice among many consumers. (30)

Why we like Gainful Creatine Monohydrate as best creatine

Creatine is one of the most popular muscle growth supplements on the market (aside from whey protein) because it aids in muscle growth and increases athletic stamina. (30) Supplementing creatine can bolster muscle creatine levels, as creatine phosphate. In turn, creatine phosphate serves as a super fast acting resource that aids the recycling of ATP, or adenosine triphosphate. (31) ATP, in layman’s terms, is what cells in the body directly use to power operations including muscle contraction when you exercise.  

Interestingly, creatine can also increase lean body mass, much via an increase in the water content of your muscles. (32) Besides increasing muscle mass, a high-quality creatine supplement may potentially improve high-intensity exercise performance such as sprinting, making it an ideal supplement for training athletes. (33)

Gainful Creatine Monohydrate stands out as a premier creatine brand thanks to the professional oversight of their Science Advisory Board. This team of sports nutritionists and Ph.D.s in sports science has specially crafted this 5-gram supplement. However, it’s important to note that Gainful does not disclose the source of their creatine, so we cannot confirm if it’s suitable for vegetarian or vegan populations. 

Additionally, Gainful Creatine Monohydrate has not been third-party tested from what we can tell. That being said, creatine is a generally safe supplement for most populations. It is, however, important to speak with a health care practitioner before beginning any supplement, creatine included, as your provider can provide personalized guidance on dosage.

Gainful Creatine Monohydrate is on the cheaper end of our highlighted supplements, clocking in at around $0.79 cents per serving while the average sits at around $1.65. Gainful automatically enrolls you in a subscription program upon purchase that renews every four weeks; that being said, you can skip, delay, or cancel this shipment at any time. With a subscription, you also receive unlimited 1:1 access to an in-house registered dietitian for nutritional advice and questions.

Why we like Nutricost Mass Gainer as best for weight gain

Nutricost Mass Gainer is a classic muscle growth supplement that also supports weight gain. This formula provides 1,240 calories per serving and has only 4 grams of saturated fat, which is another plus since the American Heart Association recommends limiting saturated fat intake to no more than 13 grams per day for optimal health. (34

This supplement contains 50 grams of whey concentrate. Although Nutricost is not explicit on which amino acids (or how much) their formula contains, whey protein contains high levels of BCAAs that promote muscle growth, making it a popular choice among many athletes and non-athletes alike. (6

The addition of L-glutamine, a building block in the formation of protein in the body, helps BCAAs work at the maximum capacity for ultimate muscle growth. (7) Additionally, this combination may aid in the reduction of soreness 12-24 hours after your workout. (8)

This formula also contains other nutrients, including 34% of your daily iron needs, an often-overlooked nutrient essential for muscle function and oxygen transport. (34

Additionally, Nutricost Mass Gainer formula contains creatine, another popular muscle growth supplement that has been proven to aid in both muscle growth and athletic performance. (30) Creatine’s ability to aid in muscle growth comes from its ability to rapidly regenerate ATP, or adenosine triphosphates, which is the direct energy molecule in cells that powers operations, like muscle contraction in muscle cells. (31

One thing to note is that the serving size of this mass gainer supplement is higher than others on our list at 3 scoops, which comes out to about 338 grams. This may be challenging for certain users to consume, but for those who are up to drinking larger amounts, especially in a traditional protein shake, this supplement could be optimal.

Due to its inclusion of whey protein, this formula is not suitable for vegans or those allergic to dairy products (there is also a peanut warning on the product’s label). However, the product has been tested by ISO-accredited laboratories and is manufactured in an NSF-certified, GMP-compliant, FDA-registered facility. This formula is also non-GMO for those on the lookout.

Nutricost Mass Gainer is more expensive than other brands at $5.00 per three-scoop serving. The company offers a subscription deal that renews every 30 days and offers 20% off each purchase, which is a significant discount.

What customers are saying

On Amazon, a small number of customers have reviewed this product, giving it a 4.6 out of 5 stars. Users most enjoy the taste of the supplement, which comes in three separate flavors: chocolate peanut butter, cookies n’ cream, and double chocolate. 

If you are trying to gain weight or add major bulk, this is for you! It’s easy to digest and blends really well in both water [and] milk. Though, If you aren’t accustomed to protein powders[,]work up to a full serving as it could be rather harsh on your stomach at first.”

Surg, verified Amazon customer

Another customer, “Roseville MTB Dad”, states that “the quantity is not outrageous for the price[,] but it is a little steep. Probably better for a more dedicated bodybuilder who is intentionally looking to bulk up.” Therefore, a cheaper, less caloric-dense option may be better for the average protein supplement consumer.

Why we like Promix Collagen + BCAA as best for women

Promix Collagen + BCAA features not only a 2:1:1 blend of BCAAs leucine, isoleucine, and valine, but also an effective dose of collagen peptides. These essential amino acids, which our bodies cannot produce, must be obtained from outside sources and are crucial for supporting muscle growth. The added collagen supports skin, hair, and joint health, making this formula a comprehensive choice for women’s fitness and wellness. (6)

As previously noted, branched-chain amino acids work at their fullest capacity when combined with other essential amino acids, of which there are nine in total. (7) Promix Collagen + BCAA contains all nine essential amino acids and remaining non-essential amino acids to further support muscle recovery and development. 

Leucine is a notable BCAA, known for its role in helping minimize damage post-workout, and in turn supporting rebuilding muscle fibers, facilitating growth and recovery. (36) The recommended dose of leucine for optimal recovery starts at 2 grams a day, and Promix’s formula features 2.7 grams of leucine.

Promix Collagen + BCAA stands out due to its inclusion of collagen peptides sourced from 100% grass-fed cattle from Brazilian partner farms. Collagen, the most abundant protein in the body, is often overlooked in mainstream muscle gain formulas but is crucial for supporting skin, joint, and muscle health. (37) It may aid in helping with joint pain management by potentially accumulating in cartilage and thereby stimulating further collagen production in the body. (38) Collagen supplements may help symptoms of osteoarthritis, as well, making them a good choice for older consumers. (35)

Collagen also has other benefits besides alleviating joint pain, however. Collagen naturally decreases as we age, and daily supplementation of collagen may help decrease signs of aging by improving skin elasticity and hydration. (39) Although this supplement is geared more toward women, all genders can benefit from collagen supplementation and should keep collagen levels high to aid in skin and joint health.

Promix Collagen + BCAA has been rigorously third-party tested, and the results are available on their website beneath each product description. As the collagen peptides in this formula are sourced from cattle, this supplement is not suitable for vegans or vegetarians. 

At $1.85 per two-scoop serving, Promix Collagen + BCAA is only slightly higher than average, and subscriptions are available that can save you 10% on each purchase and include free shipping. Subscribers can choose to receive their bundles every 30, 60, or 90 days, and they are able to pause or cancel at any time.

What customers are saying

On Amazon, 245 reviews have given Promix Collagen + BCAA 4.2 out of 5 stars. 

One verified customer, Katie, notes that she has seen a slew of health benefits, including “noticeably smoother skin,” “stronger hair and nails,” and improved digestion: 

“Not until I tried this did I feel really full and energized through the whole morning. Your digestion and energy are linked[,] and this product covers all the bases with all the amino acids it gives you.”

Katie, verified Amazon customer

Interestingly, most of the complaints stemmed from consumers who purchased the now unavailable unflavored version due to its pungent taste. From what we can see, there are no complaints about the chocolate variety, and many note that this formula mixes easily into smoothies, oatmeal, coffee, or just water. 

Overall, it seems that customers are satisfied with their Promix purchases.

Why we like Jacked Factory Growth Surge as best for weight loss

Building muscle while losing weight can be a tricky goal. Still, Jacked Factory Growth Surge makes the journey just a bit easier through a combination of creatine monohydrate, betaine anhydrous, L-carnitine L-tartrate, and BioPerine. Creatine is a go-to for many athletes and casual trainees alike, as it is proven to help build muscle growth while increasing stamina. (30) This happens because of creatine’s ability to help form ATP, which is what is broken down to produce energy when you exercise. (31)

Additionally, this formula contains 2.5 grams of betaine anhydrous. Betaine anhydrous is an amino acid derivative that may improve athletic performance. (40) Although there are a few competing ideas as to why betaine anhydrous aids in performance, some speculate that one potential mechanism is due to its ability to aid in creatine synthesis, aka the body’s ability to produce creatine for use. (42

Jacked Factory Growth Surge also provides two grams of L-carnitine L-tartrate, which has a rapid absorption and may help with recovery by lessening muscle soreness. (41) Additionally, this substance may help bring oxygen to the muscles (43) and increase the production of red blood cells. (44) Together, these attributes can contribute to overall recovery. 

Lastly, this supplement contains BioPerine, a substance made through the extraction of piperine, which is found in black pepper. The reason many supplement companies add BioPerine to their formula is because of growing evidence that BioPerine aids in the absorption of nutrients. (22) Additionally, BioPerine may hold anti-inflammatory properties and relieve those who experience chronic inflammatory diseases. (23)

At $1.33 per one-scoop serving, Jacked Factory Growth Surge is slightly more affordable than our average of $1.65 for muscle growth supplements. A subscription purchase offers 15% off and free shipping, and shipments can be chosen for delivery every 30, 45, 60 days. As a note, this supplement is labeled as a “post-workout” and is best taken either during or after a rigorous workout.

Unfortunately, we can’t find evidence of third-party testing across the Jacked Factory company. They claim to contain “research-supported doses,” but we cannot see which specific research they are referring to. That being said, the dosage found in the Jacked Factory Growth Surge supplement seems standard across the supplement marketplace.

What customers are saying

Amazon reviewers rave over Jacked Factory Growth Surge, and 70% of 6,601 reviewers give this product five stars with an overall average of 4.5/5 stars. 

 “After my workouts, I feel less soreness and more energized, thanks to the effective blend of ingredients. The Swoleberry flavor is delicious and refreshing, making it a treat to look forward to after intense sessions. It mixes easily without any gritty texture, so it’s smooth and easy to drink.”

Edmond, verified Amazon customer

Overall, reviewers enjoy the flavor choices (there is an unflavored option for those who don’t want sweetness). That being said, most of the complaints are either due to its sweetness or due to symptoms of stomach discomfort. Some populations have found that sucralose can cause stomach upset and diarrhea. (45) If you have a sensitive stomach, it may be good to opt for the unflavored version which does not include sucralose.

However, certain customers claim that they actually experienced fewer stomach issues using this product. For example, Brian R., a verified Amazon customer, states, “NO matter which brand or composition (whey, soy, vegan, whatever) of protein powder I take, it causes stomach and bowel issues.” However, after trying Jack Factory Growth Surge, he writes, “It took about 3 days before I started noticing the effects of Growth Surge. My muscles and nervous system are recovering in half the time it used to be,” and he doesn’t share any unwanted stomach-related side effects.

Why we like Transparent Labs Vitality as best for testosterone

Combining many ingredients to aid in vitality and muscle growth, Transparent Labs Vitality stands out as our best supplement for testosterone. To begin with, these capsules contain 15 milligrams of zinc—or 136% of the daily value—which aids in many health outcomes, including immunity support, wound healing, and DNA synthesis. (15) And yet, zinc is most likely included in this blend because of its role in helping in the maintenance of a healthy testosterone level. (18

Additionally, 600 milligrams of ashwagandha can help bolster testosterone levels, as some studies indicate that this traditional Ayurvedic medicine may boost testosterone in healthy adult males. (28) Beyond this, ashwagandha plays a significant role in recovery and athletic endurance by potentially increasing cardiorespiratory fitness and reducing certain markers of inflammation. (28, 29) More studies need to be conducted surrounding aswaghanda’s abilities, but these early studies provide hopeful markers for health.

Other ingredients in Transparent Labs Vitality capsules include shilajit, a traditional Ayurvedic medicine found in the mountainous regions of Asia. Shilajit is a resin-like substance, and while studies on it are limited, some clinical evaluations suggest it may boost testosterone levels. (45) Although this supplement is geared towards men, women can also benefit from it. Enhanced testosterone levels may improve sports performance and endurance regardless of sex. (19)

This multi-ingredient blend also includes 250 milligrams of quercetin dihydrate, which may aid in reducing inflammation; 125 milligrams of DIM (diindolylmethane), which may act as an antioxidant in the body; and 100 milligrams of longifolia root extract, which contains quassinoids that may help increase the ratio of testosterone to cortisol, thereby enhancing athletic performance. (46, 47, 48)

Transparent Labs Vitality also contains 10 milligrams of BioPerine, an extraction of piperine that is found in black pepper. BioPerine may aid in the absorption of other nutrients while also containing anti-inflammatory properties for a steadier recovery. (22, 23) Lastly, these capsules contain boron, a trace element that aids in bone growth and maintenance and the overall synthesis of proteins including collagen. (18)

We are big fans of Transparent Labs as they are, more than anything, transparent. Each supplement contains both a Certificate of Composition and a Certificate of Analysis so that you can rest assured that there are no trace heavy metals or other toxins in your supplement. 

At $1.83 per 2-capsule serving, Transparent Labs Vitality is only slightly more expensive than our average serving cost of $1.65 for muscle growth supplements. Subscribing will automatically shave 10% off the base price and will qualify you for free shipping. You can choose to select a frequency of 15, 30, or 45 days. 

What customers are saying

Out of all seven reviews on Amazon, Transparent Labs Vitality has achieved a rating of 4.7 out of 5 stars. 

“I am 43 years old and have been looking for a product that will bring my energy level back. I felt an immediate impact the day after the first dose. 3 weeks later I still feel that I have more energy throughout the day.”

Travis, verified Amazon customer

Complaints are few and far between–especially as there aren’t many reviews to begin with–and they mostly center around the higher price of this product.

How we test supplements

Supplements that cater to muscle growth are meant to cater to any nutritional gaps you may need help to achieve in your daily habits. Muscle growth supplements can be effective for certain populations, especially those who are high-intensity athletes or bodybuilders. No matter your lifestyle choice, however, supplements must contain high enough dosages to produce results. Of course, individual muscle mass goals vary per individual–that’s where our team steps in to provide reliable reviews that will help you make the right decision.

Learn more about each factor on our full supplements testing methodology page. Here’s how we test supplements:

Efficacy—40%

No one wants to take a supplement for fun–it’s all about results. Therefore, the majority of our testing is dedicated to whether or not your supplement will provide the health benefits that you’re looking for, specifically muscle mass gain, performance enhancement, and aid in workout recovery.

Here’s what we look for:

  • Clinical evidence
  • Calories per serving
  • Dose efficacy
  • Synergistic effects
  • Proprietary blends
Safety and side effects—35%

The FDA does not regulate supplements, therefore, it is important that our qualified testers monitor each supplement for ultimate safety. This includes looking into every ingredient and dosage to uncover any potential health risks or concerns.

Here’s what we look for:

  • Reported side effects
  • Third-party testing
  • Manufacturer accreditation
  • Artificial sweeteners

 

Value—20%

Supplements are not always cheap; overall, they are an investment in your health. Therefore, we know how valuable it is to see results, but it shouldn’t always come with a high price tag. We consider supplements at different price points that can fit a variety of budgets.  

Here’s what we look for:

  • Price per serving

 

Customer experience—5%

Customer experience, though not always considered by other reviewers, is an important part of any decision–and supplements are no different. Reviews and subscription offerings are often a good indicator of positive customer experience, as they show loyal customers who want to keep returning. We rely on third-party reviews.

  • Ease of purchase
  • Shipping and returns
  • Customer support

 


How do muscle growth supplements work? 

Muscle growth supplements alone won’t increase muscle mass. Instead, building muscle requires a three-pronged approach: eating more calories than you burn (the opposite of a weight loss strategy), consuming more protein than your body breaks down, and following a specialized workout program that targets the muscles you want to build.

Muscle growth supplements can aid this process in a variety of ways. Supplements with a focus on protein, such as whey protein supplements, provide a high amount of protein to help offset protein breakdown. Other supplements may provide high levels of creatine to pinpoint and promote an increase in levels of ATP, which is what breaks down when you exercise and provides more energy to your muscles as they work. (31)

Today, supplements are evolving beyond traditional formulas, incorporating nutrients like collagen, vitamin D3, and even herbs like ashwagandha, which may aid in muscle recovery or help reduce fatigue, depending on the dosage. Ultimately, muscle growth supplements contain a wide range of ingredients designed to achieve diverse outcomes.

Other tips for gaining muscle

Protein intake

Gaining muscle varies from person to person, but adequate protein intake is crucial. The Dietary Guidelines for Americans recommends consuming at least 0.8 grams of protein per kilogram of body weight each day. (49) But many studies have shown that even more protein is beneficial, especially if you’re trying to build muscle. The International Society of Sports Nutrition recommends consuming 1.4-2.0 g/kg per day for those who exercise regularly, and 2.3-3.0 g/kg per day for those who are trying to lose weight but want to retain lean muscle mass. (50)

It’s important to calculate your individual protein needs with the help of a registered dietitian to tailor it to your specific requirements.

Overall nutrition

Nutrition plays a pivotal role in bodybuilding, serving as the foundation for muscle growth, recovery, and overall performance. A well-balanced diet, rich in essential macronutrients—proteins, carbohydrates, and fats—ensures that the body has the necessary fuel to support intense training sessions and facilitate repair after workouts. Adequate protein intake aids in the development of lean muscle mass, while carbohydrates provide the energy needed for sustained performance. Additionally, healthy fats contribute to hormone production, which is crucial for muscle development. 

It’s equally important to hydrate properly and incorporate a variety of vitamins and minerals from whole foods, as they support metabolic functions and enhance recovery. Prioritizing nutritional strategies can significantly impact the effectiveness of training regimens and lead to better overall results in bodybuilding.

Sleep quality

Sleep is crucial for muscle building. (51) Getting the recommended 7-9 hours of sleep per night helps with muscle recovery, allowing you to build more muscle without overtaxing your body. Quality sleep is essential for your overall health and fitness goals.

Listening to your body

Pay attention to how your body responds to supplements and other dietary changes. It’s important not to continue using a supplement if it causes harm. For example, if you have a dairy intolerance, avoid whey protein, and be mindful of overconsuming certain nutrients, such as vitamin C, which can lead to issues like kidney stones. (52)

Resistance training

Resistance training is a vital component of any bodybuilding routine, as it not only helps build muscle but also enhances overall strength and endurance. By incorporating various forms of resistance, such as weights, resistance bands, or body-weight exercises, individuals can progressively overload their muscles, stimulating growth and improving performance. This form of training increases lean muscle mass and boosts metabolism, aiding in fat loss and achieving a well-defined physique. 

Furthermore, resistance training supports joint health and can improve bone density, reducing the risk of injury and osteoporosis over time. Emphasizing these benefits makes it clear that resistance training is essential for anyone looking to maximize their bodybuilding potential.


FAQs

What helps build muscle fast?

The fastest way to build muscle is multifaceted but relatively straightforward. To gain muscle, you need to consume plenty of calories, ensure you’re taking in more protein than you use, and stick to a consistent workout plan that is challenging yet safe. Supplementation can help accelerate this process, but there’s no guarantee that any single supplement will produce specific results.

Does creatine build muscle?

Creatine itself does not build muscle, but it plays a crucial role in the process that does. Creatine is made from amino acids, the building blocks of protein, which are stored in your muscles and used for energy during everyday activities. Creatine specifically helps the body produce ATP (adenosine triphosphate), an essential energy source that dictates muscle control. This can be especially beneficial for older populations at risk of losing lean muscle mass. (52)

What supplement is best for bodybuilding?

There is no definitive answer to this ongoing debate, but the most popular supplements are those that have been studied the most: whey protein and creatine. Whey protein (along with plant-based options like hemp protein) provides a significant amount of protein in small servings, helping to replenish what is used during intense training sessions. Creatine, on the other hand, supports the muscle-building process. (52, 53)
