It’s hard to discount the benefits of omega-3 supplements — be it from fish oilkrill oil, or mussels. These healthy fats may help reduce certain types of inflammation, bolster brain function, and aid with mental health issues like depression, anxiety, and seasonal affective disorder. (1) However, there are a handful of factors to consider before adding omegas to your supplement stack — dosage, specific types of fats, and sourcing ratio. It’s a lot to think about for a supplement that’s much simpler than a pre-workout or protein powder.

Suggested daily consumption for EPA and DHA fats is at least 250 to 500 milligrams combined, though many supplements go above and beyond, offering around two whole grams of these fatty acids. Since EPAs may have a closer link to inflammation and DHAs may have a closer link to mental health, you’ll want to look for a ratio adjusted accordingly to suit your personal goals. To help streamline your decision-making process, we’ve analyzed dozens of the best omega-3 supplements on the market and narrowed down our picks based on lifestyle, types of diets, and sustainability.

Best Omega-3 Supplement Overall

Fish oil is one of the most common omega-3 supplements since it typically contains abundant amounts of EPA and DHA fats. This pick has a particularly high dose of these omega-3 fatty acids.

Kaged Omega-3 Fish Oil

Kaged Omega-3 Fish Oil contains one of the higher doses of omega-3 fatty acids we’ve seen across the market. It has 3,000mg of fish oil, which includes 1,100mg of EPAs and 900mg of DHAs. While there are some omega-3 supplements that can contain more, most contain over 1,000mg of fish oil less than this supp. Plus, you only need to take two softgels for a full dose here. 

Kaged Muscle Omega-3 Fish Oil
Kaged Muscle Omega-3 Fish Oil
Kaged Muscle Omega-3 Fish Oil

Kaged Muscle delivers 3,000 milligrams of omega-3 fats (1,100mg of EPA and 900mg of DHA), which is one of the highest doses across the market. Plus, it's quick-absorbing and doesn't produce fish burps. 

And there’s no need to worry about fishy burps as this fish oil has been purified to help eliminate bad odors and tastes. However, these softgels are fairly large, so you’ll need a full glass of water, or if you have a hard time trying to swallow big pills, you may want to opt for a smaller capsule supplement. These cost around $1.00 per serving, which is more expensive than some of the picks on our list.

Who Should Buy Kaged Omega-3 Fish Oil

  • Those who want a high dose of EPA and DHA fats will like the numbers in this product. 
  • Anyone concerned about fish burps will appreciate the purification process here that gets rid of this undesirable side effect. 
  • If you prefer to get your omega-3s from fish oil (versus krill oil or a vegan alternative), this is one of the best fish oil supplements we’ve tried. 

Who Shouldn’t Buy Kaged Omega-3 Fish Oil

  • Folks who prefer to take their omega-3s in liquid form will want to steer clear of these softgels. 
  • Vegans. This product contains fish and gelatin, so it’s not a vegan-friendly supplement. 
  • Anyone who wants to save some money can find a cheaper omega-3 supp on our list. 

Omega-3 supplements may not be super fancy, but they can be an impactful addition to your supplement cabinet. This formula from Kaged boasts 3,000mg of fish oil, and doesn’t have a fishy aftertaste. 

Best Krill Oil

Compared to fish, healthy fats may be more bioavailable via EPA and DHA in krill oil to better support brain function and muscle growth. (2) This pick has 500mg of krill oil to deliver a solid dose of omega-3s in a potentially more absorbable fashion. 

Swolverine Krill Oil

Krill are tiny crustaceans that are consumed by bigger ocean creatures, like whales and seabirds. Swolverine softgels contain 500mg of krill oil, which typically provides 100mg of EPA and DHA. Their krill oil also includes 100mg of astaxanthin, an antioxidant that may help support eye health and inflammation. Krill oil presents in its most natural form (called phospholipids), which means this product may also absorb better than many general fish oils. (3)

Swolverine's Krill Oil delivers 500mg of krill oil, omega-3s in the form of EPA and DHA, and astaxanthin. This supp only requires one pill per serving and has the addition of Vanilla flavor to potentially combat a fishy aftertaste. 

Swolverine added a Vanilla flavoring to their supplement to potentially avoid fishy-tasting burps, which is a great option for those who don’t like taking fish oils and krill oils due to flavor. It’s worth noting for those who are pescatarian, this has a bovine gelatin capsule, which may not be suitable for your lifestyle. This supp costs around $0.50 per each single softgel serving. 

Who Should Buy Swolverine Krill Oil

  • Those who want their EPA and DHA from krill oil, which is thought to be a more bioavailable supp than fish oil due to its natural phospholipid form. 
  • People who want a dose of astaxanthin as well, which may help with eye health and inflammation
  • Folks who want to avoid the fishy aftertaste some fish and krill oils produce. This pick has vanilla added to it to potentially avoid the fishy taste.

Who Shouldn’t Buy Swolverine Krill Oil

  • Those who would rather take an omega-3 supplement sourced from fish. 
  • Customers looking for a higher dose of fatty acids — there are fish oils that boast higher EPAs and DHAs than this product does. 
  • Although not our most expensive pick, you can still find a cheaper option if you’re on a tight budget. 

If you prefer krill oil to fish oil, this product may absorb better, and it comes with a dose of astaxanthin, which can help reduce inflammation. The vanilla flavoring ties it all together to make this a potent and possibly better-tasting product than other fish oils on the market. 

Best Omega-3 Fish Oil

If you’re looking for a fish oil with a high dose of omega-3 fatty acids that don’t come with any fishy burps, this pick has you covered. 

Kaged Omega-3 Fish Oil

Each two-softgel serving of Kaged Omega-3 Fish Oil contains 3,000 milligrams of fish oil — including 1,100mg of EPA fats and 900mg of DHA fats. Kaged puts their fish oil through a purification process that can help eliminate the typical fishy burps you can taste with other omega-3 supplements.

Kaged Muscle delivers 3,000 milligrams of omega-3 fats (1,100mg of EPA and 900mg of DHA), which is one of the highest doses across the market. Plus, it's quick-absorbing and doesn't produce fish burps. 

This fish oil comes from sustainably sourced, wild-caught fish. However, the softgels are made from gelatin, which typically comes from cattle, so pescatarians may want to be aware of this. Kaged Omegas cost around $1.00 per serving, which is a bit higher than some of our other picks on this list. If you can swing the price tag, we think the dosages and sustainability of the supp are worth it. 

Who Should Buy Kaged Omega-3 Fish Oil

  • Customers who value sustainable sourcing will appreciate that this product is sustainably sourced from wild-caught fish
  • Folks who want a high dosage of omega-3 fatty acids. This product contains 3,000mg. 
  • People who don’t like fishy burps. The purification process here can help eliminate them completely. 

Who Shouldn’t Buy Kaged Omega-3 Fish Oil

  • Vegetarians or vegans — this supplement is made from fish and gelatin. 
  • If you don’t do well with large pills, you are probably better off finding a supplement that offers smaller softgels. 
  • If you’re on a strict budget, we have some cheaper options available on our list.

Kaged offers a high-quality, high-dose fish oil that is produced from sustainably-sourced fish, and purified to help get rid of foul-tasting fishy burps that you may find in some fish oil products. 

Best Sustainably-Sourced Omega-3

If you’re concerned about sustainable fishing, some supplements are transparent about their sourcing — like this pick, which sourced their krill sustainably from the Antarctic region. 

Kori Krill Oil

Kori Krill Oil uses krill that are sustainably sourced from the Southern Ocean to make their omega-3 supplement. Their eco-harvesting technology utilizes a submerged water vacuum that’s protected by a fine mesh net to keep anything but krill from entering. The product has received a stewardship certification from Friends of the Sea, which confirms that no endangered species are caught during operations and harm doesn’t come to the ecosystem. 

Kori Krill Oill
Kori Krill Oill
Kori Krill Oill

This product is sustainably sourced from the Southern Ocean, and offers  1,200mg of krill oil with 250mg fatty acids. You can buy this krill oil in 400mg, 600mg, and 1,200mg capsules.

It has also been third-party tested for quality and purity by Labdoor. All that aside, this is a pretty standard omega-3 supplement, offering up to 1,200mg of krill oil with 250mg of fatty acids (though the specific breakdown of EPAs and DHAs is not listed). This product comes in 400mg, 600mg, and 1,200mg capsules, so you can adjust your dosing and pill size to your personal preference. They all dose out to 1,200mg per day, but you can choose between one larger 1,200mg softgel, two smaller 600mg softgels, or three even smaller 400mg softgels servings. No matter your choice, you’re looking at spending around $0.65 per serving.

Who Should Buy Kori Krill Oil

  • People who are concerned with sustainability. This product sources its krill from the Antarctic using technology to ensure no other organisms are harmed.
  • Those who don’t want unnecessary extras — this product has been third-party tested for purity.
  • Folks who like the option between one, two, and three-pill serving sizes. 

Who Shouldn’t Buy Kori Krill Oil

  • Anyone who’s looking for a higher dose of fatty acids can find much higher serving sizes of EPA and DHA fats out there. 
  • Although fairly middle ground on price, you can still find a cheaper option if you’re on a budget. 
  • Those who prefer fish oil to krill oil.

For those concerned with sustainability, this omega-3 supplement is sourced from a specific region that isn’t very industrialized and uses technology to ensure the ecosystem is not harmed in the process.

Best Omega-3 Without Fish

If you’ve spent hours combing the internet for the best omega-3 supplements, then there’s a good chance you’ve come across krill oil. If you haven’t, it’s worth considering for its potential to lower bad cholesterol.

Swolverine Krill Oil

One of the benefits of krill oil is that it may actually be better than fish oil at lowering bad cholesterol. Contrary to fish oil, krill oil’s omega-3s come in their most natural, phospholipid form, which may enable better absorption and smoother digestion (which could also limit the fishy aftertaste). In comparison, fish oil only supplies omega-3s in the form of triglycerides, which aren’t digested as well as phospholipids. 

Swolverine Krill Oil
Swolverine Krill Oil
Swolverine Krill Oil

Swolverine's Krill Oil delivers 500mg of krill oil, omega-3s in the form of EPA and DHA, and astaxanthin. This supp only requires one pill per serving and has the addition of Vanilla flavor to potentially combat a fishy aftertaste. 

This particular krill supplement has 500mg of krill oil, which provides 100mg of EPA, DHA, and astaxanthin. While fish oil provides one to one and a half percent phospholipids, krill oil provides up to forty percent, making it more potent and potentially more efficient at removing cholesterol from your cells. (4) It comes with a Vanilla flavoring to make the supp more palatable and costs around $0.50 per serving, which is fairly reasonably priced.

Who Should Buy Swolverine Krill Oil

  • Anyone who prefers krill oil over fish oil for its easier-to-digest phospholipid form.
  • People who use an omega-3 supp to lower cholesterol. Krill is higher in phospholipid content, which may be more efficient at removing cholesterol than fish oil.
  • If you’re especially concerned with inflammation, the astaxanthin here may be able to help. 

Who Shouldn’t Buy Swolverine Krill Oil

  • Vegans who prefer a product made from plant-based sources like algae. 
  • Buyers looking for a huge dose of omega-3 fatty acids — this product only contains 100mg of EPA and DHA.
  • Folks who don’t like a Vanilla flavor may want to avoid this one. 

Swolverine’s krill oil has 500mg of krill oil to deliver both EPA and DHA fats. The one-pill serving size is a major bonus, and the vanilla flavoring is a sweet detail that makes this pick stand out. 

Best Omega-3 for No Burps

What goes down may come back up when it comes to fish oil. Many who have taken an omega-3 supplement, specifically a fish oil pill, may have experienced fishy burps. Since they might be gross for some, we sought out the best burp-friendly omega-3 pill.

Kaged Omega-3 Fish Oil

Kaged Omega-3 Fish Oil goes through a two-step process of purification and clarification to help rid the oil of any fishy smells or tastes. It also has one of the highest doses of omega-3 fatty acids on the market — 3,000mg of fish oil, which includes 1,100mg of EPAs, and 900mg of DHAs. 

Kaged Muscle Omega-3 Fish Oil

Kaged Muscle delivers 3,000 milligrams of omega-3 fats (1,100mg of EPA and 900mg of DHA), which is one of the highest doses across the market. Plus, it's quick-absorbing and doesn't produce fish burps. 

The formula is pretty simple with no extra frills, but the ingredients are well-dosed and anyone who wants to avoid the fishy aftertaste will be pleased with the purification of this supp. Though the softgels are fairly large, you need only take two per day for a full dose. Plus, Kaged makes this product from sustainably sourced, wild-caught fish. And with 30 servings per container, you’re spending around one dollar per dose. 

Who Should Buy Kaged Omega-3 Fish Oil

  • People who are looking for an omega-3 supplement with a greatly reduced likelihood of unpleasant smells and burps — this supplement has gone through purification to eliminate this potential side effect of fish oil.
  • Customers who want a particularly high dose of omega-3 fatty acids — this product has 1,100mg of EPAs and 900mg of DHAs.
  • If you’re concerned about where your fish are coming from, you can rest assured that this product is sustainably sourced from wild-caught fish. 

Who Shouldn’t Buy Kaged Omega-3 Fish Oil

  • People who want additional ingredients or nutrients in their fish oil pills may want to look elsewhere.
  • Those who don’t like taking large pills can find smaller softgels on the market. 
  • If you prefer a liquid omega-3 supplement, you’ll want to avoid this softgel product. 

Assuming you don’t like fish burps (we won’t judge you if you do), you’ll love that this formula was designed to tamp down on fishy aftertaste.

Best Vegan Omega-3 Supplement

Yes, you can get omega-3s from plants, but the only way to get the important (and absorbable) omega-3 fatty acids from non-animal sources is to go to the same source the fish get theirs — algae.

Freshfield Vegan Omega-3

What makes this product stand out is that it’s vegan and contains DPA (an elongated version of EPA that can potentially be more effective at reducing inflammation) and DHA, which are sourced from algae — not fish. Most vegan omega-3 pills don’t contain these fats. The fact that these are vegan also means there’s a lower risk of contamination from mercury, which is primarily found in fish. 

Freshfield Vegan Omega-3

These vegan capsules contain 225mg DHA and 35mg DPA, and though the bottle may seem a little more expensive than other fish oils, it’s because you are getting 180 servings per bottle. That could provide up to a six-month supply of omega-3. 

These contain 225mg DHA and 35mg DPA, and Freshfield provides the option to buy either a 60-count or 180-count bottle. You only need to take one pill per serving, and since this product is sourced from algae, that pill is less likely to cause those unwanted fish burps you typically find with fish oils. It’ll cost you around $0.40 per serving if you opt for the 60-count, and you’ll save some extra change if you choose the 180-count, which comes out to around $0.30 per serving.

Who Should Buy Freshfield Vegan Omega-3

  • Those who want a vegan omega-3 that contains omega-3 fatty acids. This is remarkably rare in vegan omega-3s.
  • Anyone concerned about mercury and heavy metals in animal-based omega-3s — since this product is vegan, there’s a lower risk of contamination. 
  • Folks who don’t like to take a lot of pills will appreciate that this supplement only requires one per serving. 

Who Shouldn’t Buy Freshfield Vegan Omega-3

  • Customers who are looking for a higher dose of fatty acids. While we do like this supplement for its vegan DPA and DHA, it doesn’t provide as much of these fatty acids as some other products on this list. 
  • People who prefer to get their omega-3s from animal sources like fish or krill.
  • Folks who prefer a flavored supplement will want to look at other options.

The capsules used to deliver heart-healthy omega-3s are usually made from fish or meat-based gelatin. This product has a plant-based capsule and the oil is derived from algae — not fish.

The Benefits of Omega-3 Supplements

A wide variety of potential effects have been ascribed to omega-3 fatty acids, specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Here’s a breakdown of their core benefits.


Taking in plenty of EPA and DHA appears to be a way to help reduce inflammation. Some research suggests that fish oil supplements can be valuable for reducing joint pain associated with inflammatory conditions like arthritis. One study published in The Journal of the American College of Nutrition found that fish oil supplements helped reduce (though not eliminate) the need for anti-inflammatory drugs among people with inflammatory and autoimmune diseases. (5)(6)

Managing inflammation isn’t just for people with chronic conditions, though. Chronic inflammation has been linked to everything from heart disease to diabetes to cancer. Reducing it where possible could be in everyone’s best interest. Folks who work out regularly experience more inflammation than the average person, so it may be extra beneficial for gymgoers and athletes. Some research suggests that one to two grams of omega-3s per day helped to “counteract exercise-induced inflammation” following strength training. (7)(8)

Mental Health

There’s decent evidence to suggest that keeping your omega-3 intake relatively high can help reduce the risk of Alzheimer’s disease and improve cognition among those already suffering from some forms of cognitive impairment. (9)(10)

Some contest these links — it’s a little less concrete than the anti-inflammatory effects — but there’s even an argument to be made that the anti-inflammatory effects can play a role in treating depression. (11)(12) More research is needed, but fish oil, especially fish oil that’s made up of over 60 percent EPA, has been seen to reduce both depression and anxiety in some research. (13)(14)

Heart Health

Evidence is a little mixed, but a few studies have shown omega-3s (especially DHA) to reduce triglycerides. (15)(16)(17)(18) Positive effects have also been seen in patients with high blood pressure, though it doesn’t seem to be as effective at lowering the pressure of folks with regular blood pressure. (19)(20)(21)(22)(23)

It’s equally as important to keep your omega-6 intake low as it is to keep your omega-3 up. While the latter is usually found in naturally raised fish and meat, the former is high in processed seed oils and fried foods and more natural foods like chicken and nuts. Research suggests that a 1:4 or even 1:2 ratio is ideal for reducing the risk of heart disease and some cancers, but the average person eats closer to 1:10 or even 1:25 in some studies. (24)

Unless your diet is very Paleo (which we mean to say natural) and loaded with fish, you should take omega-3 supplements and reduce your consumption of fried and processed food to improve your omega-3 to -6 ratio.

How We Chose the Best Omega-3 Supplements

So, how did we land on this list? Below are the criteria we used to make sure we selected the cream (or oil) of the crop.


There’s no official recommended intake, but the World Health Organization and the US Department of Health and Human Services suggest a minimum of 250 to 500 milligrams of omega-3s per day. (25) It’s important to note that many of these studies used two to four grams per day to achieve their effects.

Omega 3 supplements

Studies vary a lot in the dosages — one found that 14 grams of fish oil per day for five weeks helped improve some inflammation markers among post-menopausal women. (26) But as mentioned, the closest thing to a recommendation we have is 250 to 500 milligrams per day of a combination of EPA and DHA. Our favorite supplement delivered a solid 2.5 grams, but we didn’t penalize too harshly for lower amounts. 


EPA is a little more closely linked with inflammation, and DHA has a closer tie with mental health. They’re usually dosed on par. That said, we didn’t penalize if the dosages weren’t the same. While some limited research suggests going heavier on EPA if you want to tamp down inflammation, we suggest determining your individual preferences when choosing an EPA and DHA balance. (27)

Third-Party Testing

There are several third-party testers and regulatory bodies that producers of omega-3 supplements can employ.

  • The most popular is probably The International Fish Oil Standards™ (IFOS), which awarded five stars to our best overall pick. The Ontario-based organization focuses on three main categories: the label accuracy or the number of active ingredients on the label; the presence of contaminants like mercury and radiation, which they say can outweigh the beneficial health effects of fish oil; and the stability or how quickly the product is likely to degrade. IFOS is the only organization that tests fish oil products by batch and lot number to ensure they have the right components, don’t contain contaminants, and are both stable and fresh for consumption.
  • Another prominent organization is the Marine Stewardship Council, a global nonprofit organization that focuses on sustainability. The MSC works with fisheries, grocery stores, restaurants, and supplement companies to improve fishing practices, combat fraud, and promote transparency — to ensure that generations can enjoy seafood. Every fishery is independently assessed to figure out the impact on wild fish populations. They also track the supply chain to ensure all of their certified fish oil can be traced back to an approved fishery.
Fishing boat out to sea
  • Friend of the Sea also approved some of the supplements we looked at. A project of the World Sustainability Organization, Friend of the Sea carries out yearly audits onsite by independent international certification bodies. Their requirements include waste and energy management, social accountability, no significant impact on the seabed, and not affecting animals deemed “overexploited” by the UN’s Food and Agricultural Organization.
  • Labdoor is another highly regarded company that emphasizes label accuracy. An approval from Labdoor is highly valued in all areas of nutritional supplements — the completely independent company purchases products off of retail shelves and online sites, and then sends samples to an FDA-registered laboratory for chemical analysis.


Particularly for fish-based omega-3s, responsible sourcing can be a priority for some consumers. This is where the certifications from IFOSS, Marine Stewardship Council, and Friend of the Sea come into play.


Nobody wants rancid fish oil. Besides following the guidelines we outline below, we give extra points to companies that freeze their product soon after harvesting, helping to maintain freshness.


We’re not of the mind that omega-3 supplements should have only omega-3s and nothing else at all. Some additives can be useful — rosemary or oregano extract, for instance, appears to help inhibit their oxidation. (28) Tocopherols also appear to help protect against contaminants. (29)

fish oil dose

Therefore, we prefer omega-3s with ingredients like these, water, and glycerin (to maintain the capsules’ shape).

Best Omega-3 Food Sources 

Outside of fish, algae is another great source — and, excuse us if we’re wrong, we doubt you’re eating it by the bowlful. So, it’s back to fish. That said, not every type of fish has the same amount of omega-3s. Per one hundred grams, these are the animals that are highest in omega-3 according to NutritionData:

  • Mackerel: 5,134 milligrams
  • Salmon: 2,260 milligrams
  • Anchovies: 2,113 milligrams
  • Herring: 1,729 milligrams
  • Sardines: 1,480 milligrams
  • Oysters: 672 milligrams
  • Halibut: 669 milligrams

Do Vegan Omega-3s Work?

Vegans will have a tougher time meeting their omega-3 requirements through food alone. Algae is really the only significant vegan source of EPA and DHA, which is why it’s the base of the vegan product we recommend. But all the other plant-based foods that are frequently touted as good sources of omega-3, such as chia, walnuts, and flaxseeds, are not.

Most vegan omega-3s are alpha-linolenic acid or ALA. The problem with ALA is that the body needs to convert it to EPA and DHA, and it’s estimated that about 90 percent of it is lost in the process. (30) Plus, if you’re eating a lot of omega-6, it appears to make it even harder for the body to make this conversion. (31)

Basically, you need to consume 10 times the amount of ALA to get roughly the same amount of EPA and DHA. That said, really high amounts of ALA have been linked to an increased risk of prostate cancer. (32) It’s also been linked to lower risks of heart disease and diabetes, but doubling down on ALA might be an iffy strategy. (33)

Do Omega-3s Go Bad?

Fish oil expires. It’s animal fat, after all, and it can go rancid and lose its effectiveness. In fact, polyunsaturated fatty acids are highly prone to oxidative degeneration. According to a 2015 paper in the Journal of Nutritional Science, fish oil supplements are the most prone to degradation. (34) One study even looked at 171 supplements from 49 brands in Canada and found that 50 percent exceeded limits for at least one measure of oxidation. (35)

The risk of oxidation is affected by exposure to oxygen and light, temperature, antioxidant content, and the presence of water and heavy minerals. To minimize risks, it’s smart to keep your fish oil in the fridge. The expiration date should be printed on your bottle, and while that date is meant to undershoot the expiration and take into account that many people might not store them well, it probably refers to when the gels will expire if left unopened.

Here are some tips to help you keep your omega-3 supplements fresh:

  • Buy them one month at a time, so you’re not stockpiling older supplements.
  • Once they’re open, start taking them every day.
  • Check to ensure the oil is clear, and not cloudy.
  • The coating should be springy, not soft.
  • If they smell bad, don’t take them.

When Should I Take Omega-3s?

You can take your fish oil supplement at any time of day, but it’s recommended that you take it with a meal. The fats in fish oil can absorb better when you eat them with other fats. If you don’t eat a lot of fats at breakfast, wait until lunch or dinner. The time of day isn’t as important as the foods you’re eating with your fish oil. (35)

If you consume fish oil on an empty stomach, however, it’s possible that your fish oil won’t absorb properly, and it’s also possible you’ll feel a bit of heartburn after consumption.

How Much Do Omega-3s Cost?

Omega-3 supplements can be fairly inexpensive depending on aspects like brand, source, dosage, taste, and sustainability. To know exactly what you’re getting for your money, you’ll want to weigh the cost of the container against the number of servings total within that container. Typically, this number can range anywhere from $0.50 per serving to $2.00 per serving. On average, you can expect to pay around $0.67 per serving for a quality fish oil supplement.

Omega-3 products that are sustainably sourced, that have a higher dosage of fatty acids, or that don’t cause an undesirable fishy aftertaste are generally going to be more expensive. More basic products that may have a lower dosage, may not list sustainability practices, or may cause a fishy aftertaste tend to be less expensive in comparison.

What to Know Before You Buy Omega-3 Supplements

Before you click that ‘purchase’ button, it’s worth running through this quick checklist, so you really know what you’re after.

Buy the Right Dosage

As we’ve mentioned, there’s no official recommendation for how much omega-3 you should consume in a day, but most aim for at least one gram. Base your EPA to DHA ratio on the potential effects you’re after — if you’re more concerned with inflammation, opt for a product higher in EPAs; if you’re more concerned with brain health, opt for a product higher in DHAs. 

Consider the Rest of Your Diet

Research suggests that the efficacy of taking more omega-3 relies in part on your omega-6 intake, which is prevalent in processed oils, fried foods, and most plant fats. Try to eat more fat from wild-caught seafood, grass-fed beef, pastured chicken, coconut, chia, and olive or avocado oil.

Decide If Sustainability Matters

If sustainability is a personal priority, look for one of the aforementioned certifications or choose sources such as krill oil and algae, which have less impact on the environment. 

Speak With a Physician

Before making any changes to your diet or supplement regimen, visit a doctor to determine if it’s the right move for you and what other measures you could and should be taking for your overall health.

Final Word

Supplementing with omega-3s has been shown in various studies to help with inflammation, mental health, and brain function. (1) Although the ingredient lists tend to be pretty simple in these supps, they may have a significant impact on brain and heart health, reducing inflammation, and lowering LDL cholesterol. As an added bonus, omega-3 supplements tend to be pretty affordable regardless of which supp you choose to add to your daily routine.

How much omega-3 should I take?

There’s no one definitive answer. Definitely check with your doctor to determine if you should be taking omega-3s and, if so, what dose is right for you. That said, look for a supplement that offers at least one gram.

What organizations should I look for on labels if I'm concerned about sustainability?

  • The International Fish Oil Standards™
  • Marine Stewardship Council.
  • Friends of the Sea.
  • Labdoor (this isn’t a sustainability site, but it’s great to reference for purity and quality).

Do omega-3s only come from fish?

Nope. Fish are a fine choice, but omega-2 supplements can also be produce from krill, mussels, and even algae, which is a great choice for vegans.

What is the best omega-3 supplement?

After wading through several fish and krill oil supplements, we decided Kaged Omega-3 Fish Oil is the best overall omega-3 supplement. It contains a high amount of omega-3s, including s 3,000mg of fish oil, which breaks down to 1,100mg of EPAs and 900mg of DHAs. Kaged only requires you to take two softgels, and it costs less than a dollar per serving. Kaged also purifies their fish oil to try and combat the fishy taste many experience when taking fish oil.

How much does an omega-3 supplement cost?

Overall, an omega-3 supplement is a pretty inexpensive product to add to your stack. Quality, sustainability, and ingredients will all be factors that affect the price, but this list contains omega-3s that are all under around $1.00 per serving. Generally, these cost between about $0.33 and $0.99 per serving with an average price of $0.67, making omega-3s affordable for almost any budget.
