It can be hard to know what nutrients your body needs, especially with so many terms thrown around in everyday conversation. Chances are high you’ve heard certain vocabulary words—like omega-3 fatty acids—but are you certain what they mean and if you need more of them?
To clarify: omega-3s are fatty acids concentrated in certain foods, like fish and shellfish. They can also be taken in supplement form. There are three main types of omega-3 fats: docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), and alpha-linolenic acid (ALA), though DHA and EPA are associated with the strongest health benefits. (1)
Studies show that supplementing with DHA and EPA could benefit the health of your heart and brain and may help reduce symptoms of certain health conditions, like fatty liver disease and rheumatoid arthritis (RA). (1) Though it’s clear that omega-3 supplements offer several health benefits, shopping for an omega-3 product can be intimidating due to the overwhelming number of products available for purchase.
To make it easier for you to choose the best omega-3 supplement for your health needs, our team of nutrition professionals analyzed dozens of products, narrowing down the best of the best. These 11 supplements made the list due to their use of high-quality ingredients, rigorous testing and safety standards, and overall value.

Best omega-3 supplement for fatty liver: Sports Research Omega-3 Fish Oil
Key product features
What you should know
Containing a high dose of EPA and DHA at an affordable price, Sports Research Omega-3 Fish Oil is our top choice for treating fatty liver. (2, 3)
- We love that Sports Research Omega-3 Fish Oil is affordable, third-party tested, and certified sustainable by the Marine Stewardship Council (MSC), an international non-profit organization that sets standards for sustainable fishing.
- This product is one of the most affordable on the market, with a serving costing just $0.33.
- Packing nearly 1,000 mg of DHA and EPA into one small softgel, Sports Research Omega-3 Fish Oil is recommended for those who have higher omega-3 needs, such as those with fatty liver disease. (3)
Why we like Sports Research Omega-3 Fish Oil as best for fatty liver
Non-Alcoholic Fatty Liver Disease (NAFLD) is a common condition characterized by liver inflammation, liver cell damage, and a buildup of excess fat in the liver. People with obesity, high blood lipid levels, type 2 diabetes, and high blood pressure are more likely to develop NAFLD. (2)
NAFLD can cause several health complications, including liver cancer and liver failure, which is why managing this disease is so important. Fortunately, transitioning to a healthy diet, losing weight, and taking certain dietary supplements, like omega-3 fats, can help treat NAFLD. (3)
DHA and EPA may improve NAFLD by increasing the breakdown of fat in the liver and reducing liver fat accumulation. (3) Studies show that omega-3 supplements, like fish oil, are effective for reducing liver fat in both children and adults with NAFLD. (3)
A 2020 review of 22 studies that included adults and children found that supplementation with omega-3s significantly reduced liver fat compared with placebo treatments. The review also found that omega-3 supplements reduced triglycerides, a type of blood fat that tends to be high in people with fatty liver disease. (3)
Though the 1,040 mg dose of DHA and EPA found in one capsule of Sports Research Omega-3 Fish Oil might have beneficial effects on fatty liver disease, research suggests that higher doses are more effective. For example, most of the studies included in the review mentioned above used doses of omega-3s higher than 2 g per day. (3)
However, since Sports Research Omega-3 Fish Oil is so affordable and packs over a gram of omega-3s into one softgel, people who require higher doses to treat conditions like fatty liver can take multiple doses per day to increase their DHA and EPA intake.
Sports Research Omega-3 Fish Oil contains fish oil sourced from wild Alaskan pollock that’s certified sustainable by MSC. Plus, this product is third-party tested for stability, contaminants, and label accuracy by International Fish Oil Standards (IFOS™), an independent certification organization.
These gluten-free, non-GMO verified softgels are made using a 10-step refinement process that creates a concentrated omega-3 supplement that’s neutral in flavor, meaning there’s no fishy aftertaste. However, keep in mind that the softgels are quite large, which may be an issue for people who can’t tolerate swallowing larger supplements.
Another plus is that this product is affordable, costing just $0.33 per serving. Customers can subscribe for automatic deliveries to save 15%.
What customers are saying
Over 43,000 Amazon customers have left reviews for Sports Research Omega-3 Fish Oil. Overall, customers are satisfied with the supplement’s quality and price.
Though most customers are happy with their purchase, a few reviews mention that the large softgel is difficult to swallow. Amazon reviewer Ricky writes “These capsules are huge! I can’t take them without fear of choking. Other reviews indicate these are ‘easy to swallow’. Not for me.”

Best omega-3 supplement for rheumatoid arthritis: Lifeforce Omega
Key product features
What you should know
If you’re living with RA, taking anti-inflammatory supplements, like omega-3s, could be an effective way to manage certain RA symptoms and improve overall health.
- We like that Lifeforce Omega contains DHA and EPA in an absorbable form and also provides other health-supportive fatty acids, such as gamma linoleic acid (GLA).
- This product is the most expensive supplement in our roundup, with one serving costing $2.50.
- Taking an omega-3 supplement, like Lifeforce Omega, could help reduce inflammation and inflammation-related symptoms in people with RA. (4)
Why we like Lifeforce Omega as best for rheumatoid arthritis
Rheumatoid arthritis (RA) is a type of inflammatory arthritis that is considered an autoimmune disease. It’s a chronic condition that causes symptoms like stiffness and painful joints. (5)
Omega-3 supplements may benefit people living with RA by reducing the production of inflammatory proteins, improving symptoms like joint pain, and reducing the use of pain medication. (4)
A 2017 review found that omega-3 supplements significantly reduce pain in people with rheumatoid arthritis. (6)
However, most of the included studies used doses ranging from 1.5 to 4 g of combined DHA and EPA per day. A 3-softgel serving of Lifeforce Omega provides 970 mg of omega-3s, which is much lower than the doses shown to be effective for improving RA symptoms.
Though Lifeforce contains a lower amount of omega-3s than what many studies have found effective for treating RA symptoms, adding any concentrated source of DHA and EPA into your diet may support overall health, including cognitive and cardiovascular health, and help regulate inflammation and disease activity in people with RA. (4)
A 2022 review found that increased consumption of omega-3s through food or supplementation decreased pain and disease activity in people with RA. (7)
The DHA and EPA in Lifeforce Omega is in the form of MaxSimil® Fish Oil, a type of fish oil that’s pre-digested for optimal absorbability. Though research investigating the superiority of MaxSimil® Fish Oil over other types of fish oil is limited, its manufacturer claims that the omega-3s in MaxSimil® Fish Oil are more readily absorbed in the digestive tract.
In addition to DHA and EPA, Lifeforce Omega also contains the fatty acids gamma linoleic acid, palmitoleic acid, and stearidonic acid, all of which have anti-inflammatory effects in the body. (8, 9, 10)
Lifeforce also contains sesame seed extract, which is rich in sesamin. Sesamin is a polyphenol compound that has powerful antioxidant and anti-inflammatory properties, which could benefit those living with RA. (11)
Some studies show that high-dose sesamin supplements are effective for reducing RA symptoms, such as painful and tender joints. However, the doses used in research studies are much higher than the 60 mg of sesamin found in a serving of Lifeforce Omega. For example, a 2019 study found that supplementation with 200 mg of sesamin for 6 weeks reduced inflammatory markers and joint pain in women with RA. It’s unclear if lower doses, such as the 60 mg found in Lifeforce Omega, would have any effect on RA symptoms. (12)
Though this supplement provides several ingredients that support the health of people with RA, it does have some drawbacks. First, this supplement is extremely expensive, costing $2.50 per serving. Though the company offers $20 off the purchase price to subscribers, this product may be too expensive for most people. Also, Lifeforce Omega isn’t third-party tested, which is disappointing given its high price point.

Best omega-3 supplement for PCOS: Nutricost Cod Liver Oil
Key product features
What you should know
Nutricost Cod Liver Oil provides an affordable source of omega-3s, which could improve body composition and other health outcomes in women with PCOS.
- We like that Nutricost Cod Liver Oil is affordable, third-party tested, and contains EPA, DHA, and vitamins A and D, all of which are essential to health.
- Costing just $0.17 per serving, Nutricost Cod Liver Oil is the most affordable supplement on the market.
- Nutricost Krill Oil is a good choice for those with PCOS because it provides omega-3s plus vitamins A and D, which have been shown to improve certain health parameters in women with this condition. (13, 14, 15)
Why we like Nutricost Cod Liver Oil as best for PCOS
Polycystic ovarian syndrome (PCOS) is a condition characterized by androgen (sex hormone) excess, ovulatory dysfunction, polycystic ovaries, and insulin resistance. Women with PCOS experience increased inflammation, high insulin levels, weight gain, infertility, and many other symptoms. This condition impacts between 5–10% of women of reproductive age and can significantly affect physical and mental health. (13)
Dietary changes, such as following a low-carb, high-protein diet and taking certain supplements, such as omega-3s like Nutricost Cod Liver Oil, can help support overall health and reduce symptoms in women with PCOS. (13)
Omega-3 supplements, like cod liver oil, have been associated with improved health outcomes in those with PCOS. (16) Cod liver oil is derived from the liver of cod fish and is rich in DHA, EPA, and vitamins A and D.
Nutricost Cod Liver Oil contains DHA, EPA, and vitamins A and D, making it an excellent choice for those with PCOS. One softgel contains 170 mg of EPA and DHA and covers 83% and 30% of your daily needs for vitamins A and D, respectively.
Omega-3s, vitamin A, and vitamin D have immune-supportive, anti-inflammatory, and cellular-protective properties that can specifically benefit the health of women with PCOS by improving inflammatory markers, enhancing insulin sensitivity, improving body composition, and encouraging healthy hormonal balance. (13, 14, 15)
A 2022 study that included 185 women with PCOS found that women with higher dietary intake of omega-3s had lower insulin levels and less body fat compared to women with low omega-3 intake. Plus, women with higher blood levels of omega-3s had more muscle mass. (13)
Other studies have also shown that supplementation with omega-3s can help reduce inflammatory markers, such as C-reactive protein (CRP), and improve hormonal levels in this population. (16)
Another way that taking cod liver oil may benefit women with PCOS is by providing a concentrated source of vitamin D. Women with PCOS are more likely to be deficient in vitamin D, which can impact mood, fertility, immune function, and more. (14)
Though the dose of omega-3s is relatively small compared to other supplements on this list, studies show that improving your overall intake of omega-3s by regularly supplementing with DHA and EPA or eating foods rich in omega-3s can improve overall health in those with PCOS. (13)
In addition to providing several nutrients that may be helpful for women with PCOS, Nutricost Cod Liver Oil is one of the most affordable cod liver oil products on the market, costing just $0.17 per serving. The company also offers a 20% discount to people who subscribe for monthly deliveries.
This budget-friendly supplement is third-party tested and free from major allergens, like gluten. One downside to this supplement is that Nutricost doesn’t provide information on the sourcing of their cod liver oil, so it may not be the best choice for those who prefer knowing exactly where supplement ingredients come from.
What customers are saying
Nutricost Cod Liver Oil has mostly positive ratings on Amazon, with many customers satisfied with the cost and quality of the product.
However, some reviews mention that Nutricost Cod Liver Oil softgels are large and uncomfortable to swallow.
Amazon customer Elizabeth D. commented: “I like the Nutricost brand and the fact that their supplements are independently tested by a third party, but this is a hard pill to swallow – literally. Yes, it’s 1,000 milligrams, but still. I’d rather take 3 of my current cod liver oil supplements than one of these super-sized pills to get the same dose.”

Best omega-3 supplement for inflammation: Ora Organic Head & Heart Plant-Based Omega-3 Supplement
Key product features
What you should know
Ora Organic Head & Heart Plant-Based Omega-3 Supplement is designed help reduce inflammation thanks to DHA from algae powder.
- Each two-capsule serving of Ora’s omega-3 supplement contains 500 mg of DHA.
- At $1.67 per serving, this supplement is more expensive than other options on the market.
- This vegan-friendly product is a good choice for anyone from athletes to older adults who want to combat inflammation.
Why we like Ora Organic Head & Heart as best for inflammation
Ora Organic’s Head & Heart supplement earns our pick as best omega-3 for inflammation. Omega-3s are involved in many critical processes within the brain—such as regulating inflammation. (17) Ora’s supplement contains omega-3 in the form of DHA, which research shows can help both active and aging populations combat inflammation.
A small study in patients with rheumatoid arthritis found that consumption of DHA led to decreased inflammation and arthritis symptoms compared to a placebo group. (18) Exercise can also cause muscle soreness and inflammation, and supplementation with DHA may help counteract exercise-induced inflammation, which can help support recovery. (19) Though more research is needed, one study found that DHA was more effective than EHA in helping to control specific markers of inflammation, including interleukin-18, which plays a role in immune response and inflammation. (20, 21)
Unlike many omega-3 capsules, which contain fish oil, Ora’s capsules are filled with algae powder, making this a suitable option for vegans and vegetarians looking for a supplement to help combat inflammation. Each capsule contains 500 mg of DHA.
This supplement is made with Schizochytrium algae cultivated in an enclosed system, which the brand says helps ensure minimal impact on the marine ecosystem. Additionally, the brand uses third-party labs to test each batch for potency, heavy metal, microbial contaminants, and pathogens. Annually, products are tested for allergens, pesticides, and supplement facts verification.
Ora’s supplement costs $1.67 per serving, which makes it one of the more expensive options on the market. Additionally, each serving has 500 mg of omega-3s, which is lower than many lower-priced, fish-based options. However, if you’re a vegan or vegetarian or this supplement otherwise fits your needs, you can save via subscription or by purchasing multiple bottles at once.
What customers are saying
Ora Organic Head & Heart has mostly positive online reviews, especially among customers who are looking for a vegan, non-GMO supplement. Over 40 Amazon reviewers give this product an average 4.5 out of 5.
Some reviewers report that despite being algae-based, Ora’s capsules still have a fishy taste and smell.
“I wish I could give it 5 stars because I really value pure high quality ingredients. However, it tastes more fishy than actual fish capsules. I am pregnant but no longer in the nauseous stage and still, I gag every time I take these. I can barely get them down and then I continue to taste the fishy taste long after. They’re not refundable so I’ll finish the bottle but then I’ll have to continue my search for something else that doesn’t have fillers, etc, but is hopefully easier to take,” says Amazon reviewer A and E.

Best vegan omega-3 supplement: Calgee Vegan Omega-3
Key product features
What you should know
The Calgee Vegan Omega-3 supplement provides a plant-based source of EPA and DHA, which tend to be low in vegan diets.
- Calgee Vegan Omega-3 is third-party tested, and contains vegan-friendly algal oil.
- At $1 per serving, this supplement falls in the middle of our list as far as price point is concerned, but it does contain a lower dose of omega-3s compared to fish-based options.
- This product is a good choice for vegans, as it contains DHA and EPA derived from algae.
Why we like Calgee Vegan Omega-3 as best vegan
Seafood is a major dietary source of DHA and EPA. Since vegans don’t eat seafood, they tend to have a harder time getting these nutrients. Although you can get omega 3 from seaweed or algae, it’s often recommended that people following plant-based diets supplement with omega-3s to maintain optimal blood levels of these essential fatty acids. (22)
The omega-3s in this supplement come from algal oil—a source of essential omega-3 fats safe for people following plant-based diets derived from microalgae, most commonly schizochytrium sp. These supplements are a safe choice for vegetarians and vegans who want to increase their omega-3 intake and have been shown to be effective for raising blood levels of DHA and EPA in people following plant-based diets. (23, 22)
Calgee Vegan Omega-3 is made with algal oil derived from schizochytrium sp., which is the most common source of algal oil used in plant-based omega-3 products. (24) Vegans and vegetarians will appreciate that this product contains no fish and the capsules are tapioca instead of gelatin.
In addition to using US grown algae, we appreciate that Calgee ships with compostable mailer bags and donates a portion of its sales to environmental nonprofits.
This product is third-party tested for purity and potential contaminants like heavy metals, fish allergens and crustacean allergas, as well as a fatty acids analysis. It’s also free from carrageenan, a food additive that may trigger or worsen intestinal inflammation. (25)
At $1 per serving, Calgee Vegan Omega-3 falls in the middle range of our list. Each serving contains 550 mg of omega-3s per serving, including 450mg EPA and DHA. While there is no current dietary guideline for the recommended daily allowance of EPA and DHA, research has found that EPA and DHA may help support heart health, among other benefits. (26, 27)
What customers are saying
Calgee Vegan Omega-3 has mostly positive product reviews on Amazon. Over 160 purchasers rate this product an average of 4.2 out of 5. Customers like that the product is not fish based, making it a fit for those who follow a vegetarian or vegan diet and report there is no unpleasant or fishy aftertaste that can occur with omega-3 supplements.
Though most customers seem satisfied with their purchase, a few reviews mention the product has an unplesant smell.
Verified Amazon buyer Carrie C. wrote: “The seaweed smell is over powering—hard to put in mouth without gagging.”

Best omega-3 supplement for pregnancy: Ritual Essential for Women Prenatal Multivitamin
Key product features
What you should know
Ritual Essential for Women Prenatal contains several nutrients essential to maternal and fetal health, including vitamins, minerals, and the omega-3 DHA.
- This OBGYN-recommended, third-party tested formula contains vitamins and minerals that support healthy pregnancy and also provides DHA, which is lacking in most prenatal vitamin products. (28)
- Costing $1.30 per serving, Ritual Essential for Women Prenatal is more expensive than most other omega-3 products. However, it’s also a more comprehensive product than the other supplements on this list and is comparable in price to many prenatal vitamins.
- This vegan-friendly product is a smart choice for pregnant people who want a comprehensive prenatal that contains DHA.
Why we like Ritual Essential for Women Prenatal as best for pregnancy
When you’re pregnant, your need for several nutrients increases to support the demands of growing a healthy baby. Calcium, iodine, magnesium, choline, zinc, folate, B12, and omega-3s, are just a few examples of nutrients in higher demand during pregnancy. (28)
Pregnant people need more omega-3s due to their role in fetal development, including fetal brain development. Though both DHA and EPA are important for pregnant people, groups like the World Health Organization (WHO) recommend a minimum intake of 200-300 mg of DHA per day in order to support fetal development and prevent birth complications, such as preterm birth. (29)
Unfortunately, many pregnant women have to take a separate omega-3 supplement, as most prenatal vitamins lack these essential nutrients.
Ritual Essential for Women Prenatal stands out from other prenatal vitamins as it contains 350 mg of DHA sourced from algae, which exceeds the minimum daily amount recommended by the WHO. (29)
In addition to DHA, this product provides vitamins and minerals needed in higher amounts during pregnancy, including vitamin D, folate, iron, and iodine. Though this prenatal is generally well-rounded and gets major points for providing DHA, it is low in two nutrients essential for pregnant people—magnesium and choline. (28)
The Ritual supplement only provides 8% and 10% of your needs for magnesium and choline, respectively. Choline is essential for fetal and placental growth and development, while magnesium is critical for healthy blood sugar and blood pressure regulation. (30, 31).
So, while Ritual Essential for Women Prenatal does provide many nutrients that pregnant people need more of, it’s not as comprehensive as other prenatal products on the market. Nevertheless, Ritual Essential for Women Prenatal can help fill nutrient gaps during pregnancy and provide DHA, which supports fetal development.
Due to its comprehensive formula and commitment to quality and safety, Ritual Essential for Women Prenatal is recommended by healthcare professionals like OBGYNs. Each batch is third-party tested for purity and composition, as well as major allergens, microbes, and heavy metals, so you can rest assured you’re purchasing a safe product. Additionally, the vegan capsules are essenced with mint or citrus, making them less likely to trigger nausea, a symptom commonly experienced by pregnant people, especially during the first trimester. (28)
At $1.30 per serving, Ritual Essential for Women Prenatal is one of the priciest omega-3 supplements on the market. However, it’s moderately priced compared to similar prenatal products.
It’s important to note that Ritual is a subscription-based supplement service, meaning that customers sign up for a monthly supplement delivery on the Ritual website. This makes it a convenient choice for some people, like busy parents, but those who don’t like automated supplement delivery may want to choose a different product or make a one-time purchase on websites like Amazon.
Check out our full Ritual vitamins review for more information.
What customers are saying
Ritual Essential for Women Prenatal has mostly positive online reviews, with customers reporting that the product is high-quality, easy to take, and doesn’t trigger nausea.
However, while most people report that the tablets are easy to take, others complain that the pills have a fishy aftertaste and aren’t the best choice for people who are easily nauseated.
“Ritual is a solid brand. I researched a lot of prenatals and ended up trying these. I took them for a few months and noticed some solid results, one big one being that my nails were a lot stronger than they had ever been. The pills are easy to swallow and have a pleasant citrus scent, however, the aftertaste (burps.. I’m sorry but if you’re pregnant you get it) is disgusting. I am assuming it is related to fish oil but it became unbearable and made me super nauseous so I quit taking them,” commented Amazon customer McKynlee.

Best high dose omega-3 supplement: Legion Athletics Triton Fish Oil Capsules
Key product features
What you should know
Legion Athletics Triton Fish Oil Capsules contain the highest dose of omega-3s in our roundup, making it a good choice for those with increased omega-3 needs.
- Legion Athletics Triton Fish Oil Capsules is made with oil derived from fish caught in fisheries certified by Friend of the Sea, a certification that ensures seafood products, like krill, are responsibly caught and managed.
- At $1.67 per serving, this product is the second most expensive supplement in our roundup, which makes sense because of the high dose of omega-3s per serving.
- Some people, such as those with high triglycerides, may require higher doses of omega-3 than what’s found in most supplements. Supplying 2,400 mg per serving, Legion Athletics Triton Fish Oil Capsules is an appropriate option for these populations. (32)
Why we like Legion Athletics Triton Fish Oil Capsules as best high-dose
Legion Athletics Triton Fish Oil Capsules provide 2,400 mg of EPA and DHA per 4-softgel serving, making it a suitable option for people who require higher doses of omega-3s. Most fish oil supplements contain less than 1,000 mg of DHA and EPA per serving. While this amount may be appropriate for many people, including those who want a convenient way to boost their omega-3 intake, those with certain health conditions may require a more concentrated supplement.
For example, studies show that supplements providing more than 2 g of DHA and EPA per day are effective for reducing high blood lipid levels, such as high triglycerides and high LDL cholesterol. (32)
Having high triglyceride and LDL cholesterol levels significantly increases your risk for developing heart disease. Fortunately, making dietary and lifestyle changes, such as transitioning to a higher-fiber diet and taking high-dose omega-3 supplements, can reduce these risk factors (32)
Other populations that may benefit from higher-dose omega-3 supplements include people with fatty liver disease and those with rheumatoid arthritis (RA) due to its anti-inflammatory properties. (3, 4)
Legion Athletics Triton Fish Oil Capsules are packed with fish oil derived from Peruvian anchovies and sardines caught from fisheries certified by Friend of the Sea, a non-profit organization that monitors fisheries to ensure they use sustainable and ethical practices.
In addition to using sustainable ingredients, each batch of Legion Athletics Triton Fish Oil Capsules is third-party tested for purity and potency. Though the product is tested for allergens, it’s unclear if this supplement is gluten-free or safe for those with severe allergies.
At $1.67 per serving, Legion Athletics Triton Fish Oil Capsules is the second most expensive product in our roundup. However, supplements that provide higher doses of omega-3s tend to be more expensive than those that contain smaller doses. Customers can save 10% by subscribing to automatic monthly deliveries, but Legion Athletics Triton Fish Oil Capsules may not be the best choice for people on a budget.
What customers are saying
Despite its high price point, Legion Athletics Triton Fish Oil Capsules has glowing reviews on Amazon. Customers appreciate the dose of omega-3s per serving and the high quality of the product
However, a few reviews mention that the product they received had a fishy smell and taste. “I am a huge fan of Legion, their philosophy, customer service, hell I love all their supplements and workout shirts. WITH that said these are the nastiest smelling and tasting fish oil supplements I’ve ever used- seriously revolting smell and taste. I’m sure it’s good quality and I’m forcing them down, one in morning and evening, but I don’t think I will be buying these again, and they are not inexpensive to boot!” writes Amazon customer Multifuel.

Best omega-3 supplement for women: Transparent Labs Krill Oil
Key product features
What you should know
Transparent Labs Krill Oil is made with Superba 2™, a potent form of krill oil that’s rich in nutrients like astaxanthin and choline, making it a solid choice for those looking to support their health with a high-quality supplement. (33, 30)
- We love that Transparent Labs Krill Oil is made with sustainably sourced Superba 2™ and that Transparent Labs offers a Certificate of Analysis (COA) for all of their products.
- At $1.17 per serving, this product is a bit more expensive than other supplements on the market.
- Krill Oil may help alleviate period pain or lessen the need for pain medication for PMS symptoms. [34]
Why we like Transparent Labs Krill Oil as best for women
Not only is Transparent Labs Krill Oil made with one of the most well-researched forms of krill oil, but it’s sustainably-harvested and Informed-Choice Trusted by Sport, which is why it’s our choice for best omega-3 supplement for women.
Each serving of Transparent Labs Krill Oil contains 1,000 milligrams (mg) of Superba 2™, a high-quality and bioavailable form of krill oil harvested from sustainably sourced Antarctic krill. Superba 2™ is rich in EPA, DHA, and astaxanthin, a pigment with powerful antioxidant and anti-inflammatory properties that’s been shown to support the health of the cardiovascular system. (33)
Superba 2™ also contains choline, a nutrient that’s essential for early brain development and the regulation of memory and mood. Due to its role in brain development, choline is especially important during pregnancy, one reason we like this supplement as an option for women. (30).
Each two-softgel serving of Transparent Labs Krill Oil provides 50 mg of choline, 100 micrograms (mcg) of astaxanthin, and 220 mg of omega-3s. Though Transparent Labs Krill Oil does provide DHA and EPA, it provides a relatively small dose.
Doses of omega-3s most commonly linked to health benefits, such as a reduced risk of heart attack and heart disease-related death, typically range from 0.4 g to 5.5 g per day. (35) For this reason, this supplement may not be the best choice for those who require a higher dose of DHA and EPA. Nevertheless, Transparent Labs Krill Oil provides a combination of nutrients and antioxidants, such as DHA, EPA, choline, and astaxanthin, that could support general health and wellness.
Superba 2™ is made from krill harvested from the Antarctic krill fishery using sustainable methods, making Transparent Labs Krill Oil a good choice for those who want to support companies that prioritize sustainable practices.
Transparent Labs Krill Oil supplement is Informed-Choice Trusted by Sport. Informed-Choice is a monitoring program that certifies that supplements have been regularly tested for substances banned in sports, such as stimulants and anabolic agents. Additionally, all Transparent Labs supplements are third-party tested for purity and quality.
Transparent Labs Krill Oil is also free from artificial colors and sweeteners, GMOs, and major allergens, like gluten. At $1.17 per serving, this product is pricier than most of the other products on the market, but customers can sign up for a subscription to save around 10% on their order and get free shipping.

Best omega-3 supplement for dry eyes: Onnit Krill Oil
Key product features
What you should know
Onnit Krill Oil is an affordable source of DHA and EPA that provides a solid choice for those who need to bump up their omega-3 intake to soothe dry eye symptoms.
- Onnit Krill Oil is certified by the Marine Stewardship Council (MSC), ensuring that the krill oil used in their product was sourced using responsible and sustainable methods.
- Compared to similar products, Onnit Krill Oil is more affordable, costing just $1 per serving.
- Though studies show that higher doses are more effective for improving dry eye symptoms, taking Onnit Krill Oil can help increase total DHA and EPA intake, which may benefit those with dry eye. (36)
Why we like Onnit Krill Oil as best for dry eyes
Dry eye disease (DED) is an uncomfortable condition that causes inadequate tear production or suboptimal tear quality, which leads to dry eyes, blurred vision, and sun sensitivity. (36) Due to their anti-inflammatory properties, omega-3 supplements may be helpful for people living with DED.
One of the causes of DED is inflammation on the surface of the eye. Studies show that DHA and EPA may help reduce the production of proinflammatory proteins in the eye, thus improving DED symptoms. (36)
This made Onnit stand out to us over other brands. Onnit Krill Oil contains 240 mg of DHA and EPA. The studies included in the review mentioned above used doses ranging from 600-3,000 mg per day. (36)
Though the amount of DHA and EPA found in a dose of Onnit Krill Oil is much lower than what’s thought to be effective for treating dry eye, one could take multiple doses of this supplement to bump up their omega-3 intake.
A 2023 review of 19 studies found that people with DED treated with omega-3 supplements had more significant improvements in dry eye symptoms, such as eye dryness, compared to those who received placebo treatments. (36)
However, not all studies have found omega-3s to be effective for reducing dry eye symptoms. Plus, the doses of EPA and DHA used in most research studies are much higher than what’s found in the average fish or krill oil supplement. (1)
Onnit Krill Oil is made with sustainably harvested krill oil certified by MSC. It’s also free from major allergens like gluten and soy and is relatively affordable compared to the other supplements on this list, costing $1 per serving. However, keep in mind that if you take multiple servings per day to treat dry eye symptoms, this product becomes much less affordable.
To save more money, customers can sign up for a subscription to save 25% on their purchase.
Though this product is made with high-quality krill oil harvested from the Antarctic Ocean, it’s not third-party tested, which is a major downside. Third-party testing helps ensure that supplements are free from harmful contaminants, like heavy metals, and meet quality and safety standards.
What customers are saying
Onnit Krill Oil has generally positive customer reviews. Customers appreciate the easy-to-swallow softgels and report that they don’t have the fishy aftertaste that’s common with other krill and fish oil products.
Negative reviews are limited, but some customers report that their supplement had a strong fishy odor and that taking the supplement upsets their stomachs. “Upset my stomach. It had a fine taste but since I couldn’t stomach it I can’t speak to long-term benefits,” commented Vitacost customer RyanDay.

What you should know
Providing 1,600 mg of omega 3s, Momentous Omega-3 is a solid choice for those looking for a natural way to support and protect their brain health. (37)
- Momentous Omega-3 is NSF-certified, provides a high dose of omega 3s, and is made with fish oil sourced from anchovies, sardines, and mackerel, which are low in contaminants, like mercury. (38)
- At $1.27 per serving, this product is more expensive than most products on the market. However, it contains a high dose of omega 3s, which we believe justifies the higher price point.
- Omega 3 supplements have been shown to improve certain aspects of cognitive health, such as memory and attention, making Momentous Omega-3 an excellent option for older adults and anyone looking for an effective way to support brain health. (37)
Why we like Momentous Omega-3 as best for brain health
Choosing a supplement specifically to boost your brain health sounds like a big task—but the omega-3 from Momentous earns our vote. Taking a higher-dose omega-3 supplement, such as teh choice from Momentous, can help boost DHA and EPA levels in your blood, which may enhance cognitive function and protect against cognitive decline. (17)
Omega-3s are critical for the health and functioning of the brain. Your brain is made of around 20% polyunsaturated fatty acids, with the most common being DHA. In addition to being an important structural component of the brain, omega-3s are involved in many critical processes within the organ, including the creation of new nerve cells and the regulation of inflammation. (17)
Studies show that supplementing with omega-3s and having higher blood levels of omega-3s can benefit brain health in several ways, including protecting against cognitive decline and boosting brain function, including attention and memory. (17)
Momentous Omega-3 provides 1,600 mg of omega-3s, which is a much higher dose than most omega-3 supplements. Studies show that higher-dose omega-3 supplements, such as those that provide between 1-4 g of omega-3s, could improve cognitive-related outcomes, including memory and attention. (37)
Plus, people with higher intakes of omega-3s are less likely to develop cognitive impairment. (39)
In addition to providing a clinically effective dose of omega-3s, Momentous Omega-3 is free from major allergens, like gluten, and is NSF Certified for Sport®. NSF Certified for Sport is a certification program that verifies that products are free from the 290 substances banned by major athletic organizations.
A 2023 review that included 82 studies found that 43.6% of the included studies reported positive cognitive outcomes after supplementation with omega-3s compared to placebo treatments. The review also found that 66.7% of the included studies involving older adults with mild cognitive impairment reported a positive cognitive outcome after omega-3 supplementation compared to placebo treatments. (37)
Research also suggests that older adults with higher blood levels of omega-3s have better cognitive function, including better memory and processing speed, as well as improved overall brain health compared to adults with lower omega-3 levels. (40)
At $1.27 per serving, Momentous Omega-3 is more expensive than many omega-3 supplements. However, the price reflects its high omega-3 content. Customers can sign up for automatic monthly deliveries to save 25% on their first order and 10% on all future orders under the subscription.
What customers are saying
This product has lower ratings on Amazon compared to the other supplements in our roundup.
Positive reviews mention that the pills are easy to tolerate and don’t leave a fishy aftertaste.
However, many customer reviews mention that the product has a strong fishy smell and aftertaste.
“Second time ordering and upon opening encountered a strong fish scent and all pills covered in oil. Not sure if they’re still safe to consume,” commented Amazon customer Barron B.

Best omega-3 supplement for kids: Nature Made Kids First Multi with Omega-3
Key product features
What you should know
If your child is a picky eater or isn’t able to meet their nutrition needs through diet alone, it’s recommended to give them a multivitamin. Nature Made Kids First Multi with Omega-3 provides vitamins, minerals, and omega-3s in kid-friendly doses.
- We like that Nature Made Kids First Multi with Omega-3 is third-party tested, affordable, and comes in a tasty gummy form, which is easier for kids to tolerate than pills.
- This product’s cost varies between $0.25-$0.50, depending on the serving size your child requires. Because this product contains a much lower dose of omega-3s than adult supplements, it’s more affordable than the other products in our roundup.
- Many children have dietary restrictions and don’t like to eat omega-3-rich foods, like fish. Supplementing your child’s diet with a product that provides omega-3s is an easy way to ensure they’re getting adequate amounts of these important fatty acids.
Why we Nature Made Kids First Multi with Omega-3 as best for kids
Nature Made Kids First Multi with Omega-3 is a low-dose gummy multivitamin that provides a small amount of DHA and EPA, which may be appropriate for kids.
Omega-3s play a critical role in brain development and cognitive function and are especially important for growing children. For example, DHA is involved in the development of nerve cell networks in the brain, which is essential for brain development and cognitive function. (41)
Though there is no recommended daily intake level for DHA and EPA for kids, studies show that supplementing kids with these omega-3s may support their overall health and reduce symptoms of several health conditions.
For example, a 2022 study that included 120 6-12-year-old children found that those who were supplemented with 260-520 mg of DHA for 12 weeks experienced improvements in attention and cognitive processing ability compared to kids who received a placebo treatment. (41)
Omega-3 supplements have also been shown to improve other aspects of health in children, including lowering triglyceride levels and improving fatty liver. (3, 42)
Nature Made Kids First Multi with Omega-3 provides several vitamins and minerals as well as a relatively low dose of DHA and EPA. Each gummy contains 30 mg of combined DHA and EPA, which is a much lower dose than those used in research studies assessing the effects of omega-3 supplements in children.
Because it contains a low dose of omega-3s, this product is a better choice for children without medical issues or increased nutritional needs.
Though it contains a low dose of omega-3s, this product provides several other nutrients essential for growing children, such as vitamins B12 and D, which are required for central nervous system development and proper bone mineralization, respectively. (43, 44)
Nature Made Kids First Multi with Omega-3 comes in a chewable gummy form, which is easy for kids to tolerate. The gummies are sweet and fruit-flavored, but parents and caregivers should be aware that each gummy contains 2 g or half a teaspoon of added sugar. Because sugar, especially in gummy form, can damage teeth and cause cavities, it’s important for kids to rinse their mouth out with water after taking this product. (45)
Nature Made Kids First Multi with Omega-3 is verified by the United States Pharmacopeia (USP), a non-profit organization that sets strict, product-specific standards for the quality, purity, and identity of dietary supplements. This product is also free from major allergens, like gluten, as well as artificial colors and flavors.
Cost per serving varies from $0.25–$0.50, depending on age range. Though this product is cheaper than most of the adult supplements on our list, it’s comparable to other children’s gummy multivitamins.
What customers are saying
Due to its sweet and fruity flavor, Nature Made Kids First Multi with Omega-3 seems to be a hit with kids.
Amazon customer Kristina Gallegos-Dudman writes, “Bought these after trying several for my daughter. She loves the taste of these vitamins compared to several others we have tried.”
Though most customer reviews are positive, some reviews mention that the gummies are too sour and too high in added sugar for kids.
“The vitamins were coated with so much sugar. The gummies are extremely tart. I thought my child was over exaggerating, so I tried one – awful,” wrote Amazon customer Kindle Customer.

Benefits of omega3 supplements
From providing your body with energy to supporting your cardiovascular system, omega-3 supplements offer a variety of health benefits. Below are a few key advantages of incorporating omega-3s into your diet.
Could benefit heart health
Research shows that supplementing with omega-3s may reduce heart disease risk factors like high triglyceride and cholesterol levels, decreasing inflammation, and supporting and protecting brain health. (1) It can support heart health by lowering inflammation in the arteries, reducing blood lipid levels, and improving blood flow. (35, 46)
Reviews of research show that omega-3 supplements could lower the risk of heart attack, heart disease, and death caused by heart disease. (46)
A 2019 study found that every 1,000 mg per day dose of DHA and EPA corresponded to a 7% and 9% reduced risk of total coronary heart disease and heart attack, respectively. (46)
Keep in mind that people with certain conditions that raise heart disease risk, such as high triglycerides, may require higher-dose omega-3 supplements. (32)
If you have questions regarding omega-3 dosing for heart disease prevention, consult your healthcare provider.
Has powerful anti-inflammatory properties
DHA and EPA have powerful anti-inflammatory properties and help regulate inflammation in the body. Studies show that omega-3 supplements are effective for lowering inflammatory proteins like c-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6), which are often elevated in inflammatory conditions like RA and inflammatory bowel disease (IBD). (4)
Omega-3 supplements may benefit people with increased inflammation by lowering disease activity, inflammatory markers, and inflammation-related symptoms.
For example, studies show that omega-3 supplements delivering doses of combined DHA and EPA ranging from 1.5 to 4 grams may significantly reduce pain in people with rheumatoid arthritis. (6)
EPA and combined EPA and DHA have also been shown to reduce intestinal inflammation, induce remission, decrease disease activity, and improve the quality of life in people with IBD. (47)
Could support and improve brain health
Omega-3s are critical to the development, function, and overall health of the brain and nervous system. These fats regulate brain inflammation, are required for nerve cell development, and impact levels of mood-regulating neurotransmitters, like serotonin. (17)
Studies show that supplementing with omega-3s may protect against cognitive decline, promote cognitive function, and even improve symptoms of mental health disorders like depression.
Research findings suggest that supplementing with omega-3s could improve cognitive outcomes like attention, processing speed, and memory in kids and adults and that having higher blood levels of omega-3s may protect against cognitive decline. (37, 48, 39)
In addition to the benefits listed above, taking omega-3s may help improve symptoms of depression.
A 2019 review that included 26 studies found that omega-3 supplementation had an overall beneficial effect on depressive symptoms. The review noted that daily supplementation with formulations containing 60% or more EPA and providing at least 1 g of EPA were most effective for improving depressive symptoms. (49)
How to choose the best omega-3 supplement for you
When shopping for an omega-3 supplement, it’s best to consider your health needs, budget, and dietary preferences.
It’s best to choose products from trusted brands that have undergone third-party testing for quality, purity, and potential contaminants like heavy metals when possible.
Additionally, people with food allergies and dietary restrictions should choose products that suit their health needs and preferences, such as products that are free from major allergens.
It’s also important to consider the dose and source of DHA and EPA. For example, people following plant-based diets may require an omega-3 based on algal oil, while people with certain health conditions, like high triglycerides, may need a higher dose of omega-3s than what’s found in most supplements. Lastly, it’s always best to consult your healthcare provider to ensure that adding an omega-3 supplement to your diet is a safe and appropriate for your health needs. (50)
Potential side effects of omega 3 supplements
Omega-3s are generally considered safe, but high doses aren’t safe or appropriate for everyone. (50)
Though higher doses of DHA and EPA may benefit health conditions like high triglycerides, the FDA recommends that daily intake not exceed 3 g of combined DHA and EPA, with no more than 2 g per day from supplements. (50)
Unless specifically recommended by a healthcare provider, you should avoid exceeding 2 g of DHA and EPA per day. Taking very high doses of supplemental omega-3s may impact immune function, inflammatory response, and your body’s ability to properly clot blood. (50)
Additionally, at high doses, omega-3 supplements may interact with blood-thinning medications, including Warfarin (Coumadin), increasing bleeding risk. (50)
Taking omega-3 supplements may also lead to side effects, such as diarrhea, nausea, gas, and a fishy aftertaste. (50)
Though these side effects aren’t dangerous, they can be uncomfortable. Talk to your healthcare provider if you experience side effects after taking an omega-3 supplement. Depending on the symptom, they may recommend switching to another product or lowering the dose of omega-3s.
