The best fish oil supplements provide at least 1,000 mg EPA+DHA omega-3 fatty acids per serving, are certified by third-party labs and are sustainably sourced. To determine our top picks, we spoke with five doctors specializing in nutrition, consulted over a dozen scientific studies, and read hundreds of ingredients labels. Finally, we brought in our favorite three to experience ourselves.

How We Chose the Best Fish Oil Supplements
We started with a mega-list of fish oils — nearly 200 in all. But because supplements don’t undergo the strident, top-down policing of prescription drugs, it was important to vet this list by way of independent testing. We required our picks to be approved by at least one third-party organization.
Several kinds of omega-3 fatty acids are present in fish oil, including two of the three essential for humans: Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). (The third — ALA, or alpha-linolenic acid — crops up in non-fish foods. We talk more about food sources of various omega-3s here.)
The World Health Organization and Consumer Lab both recommend 500 mg combined EPA and DHA for a minimum daily dose. We required all of our top picks to provide at least that in two or fewer soft gels. No one likes taking more pills (and paying for them) if they don’t have to.
No added colors or flavors
Color and flavor additives can disguise rancid fish oil in supplements that might otherwise look and smell like something you shouldn’t eat. What’s more, the easiest fish oil supplements to take — fruity chewables — typically contain a puny amount of nutrients. You might as well be administering Swedish Fish. We hate to say it, but fish oil should smell and taste like fish.
Five-star rating from the Marine Stewardship Council (MSC)
You can’t responsibly talk about consuming fish oil without talking about sustainability. Real, wild fish go into the fish oil supplements we consume, and they’re an important part of the ocean ecosystem. If any population is over-harvested, it causes a ripple effect all the way up and down the food chain.
In order to keep overfishing in check, the Marine Stewardship Council evaluates fisheries to make sure they use sustainable practices. To earn the MSC “blue label,” a fishery must take only a sustainable amount of fish out of the water, ensure its operations have a low environmental impact and comply with all relevant laws. Purchasing fish oil that aligns with MSC ethics means that what bolsters your health, bolsters the health of the product’s original ecology, too.
Guide to Fish Oil
As always, talk to your doctor
If you’ve ever looked into any nutritional supplement — be it biotin to make your hair grow or a B complex to quell anxiety — you know that the medical community is a perennially hung court. Studies are inconclusive. When it comes to fish oil, it has been proven effective against triglycerides but not much else, and some experts warn it can negatively interact with medications or exacerbate health problems. Talk to your MD to find out if some common concerns with taking fish oil (thinning blood, for example) should concern you.
Know if you’re already getting enough omega-3s
A supplement is designed to… well, supplement. If your diet is already rich in fish and omega-3-stocked nuts and grains, you probably don’t need to augment it with daily capsules. For the majority of North Americans, this won’t be the case. Western populations exhibit half the bodily supply of EPA+DHA than the population of Japan, where fish consumption is much higher.
Identify what is important to you in a fish oil supplement
People praise fish oil for soothing their joints and lowering their blood pressure, but it won’t have a chance to create any positive effects in you can’t afford it or can’t stomach it. Identify whether it’s price, flavor, or background practices that most impact your perspective, and shop accordingly.
Get the dosage right
As with any good thing, you can overdo fish oil, too. Even if you’re taking a top-of-the-line supplement that has been third-party tested for purity, like any of our top picks, an excessive dose can mess with your body. A standard daily dose of EPA+DHA: 1,000 mg. The FDA states that daily consumption should not exceed 3 grams (3,000 mg).
Like aspirin, fish oil is a blood-thinner, which makes it desirable for lowering blood pressure and reducing the risk of heart disease. “Too much fish oil increases bleeding time,” confirmed Dr. Rachel Carlton Abrams, author of Body Wise. “And that means for procedures, for injuries, if you fall and hit your head, you can bleed, like you’re taking aspirin.”
