10 Best Omega 3 Supplements With Clean Sourcing
The Good Trade editors endorse products we’ve personally researched, tested, and genuinely love. Learn more about our methodology and business model here.
We’ve used and researched the best clean supplements for years. These are our favorites for omega-3 that are thoughtfully sourced, third-party tested for toxins, and have minimal taste and odor.
Getting enough omega-3 fatty acids — sometimes called fish oil — in our diet can be challenging, especially if you don’t like or eat fish. (Even though fish is a main natural source for omega-3s, we’ve found some fish-free vegan options to try!) We love the below brands for offering docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) — two types of polyunsaturated fatty acids and types of omega-3 fatty acids — in easy supplement form. Having enough omega-3s keeps our organs and overall body functioning. Keep reading to learn more about the benefits of omega-3s and also the brands we trust most for getting our daily recommended intake!
What is omega-3 good for?
“Omega-3 fatty acids have been found to reduce inflammation [and] support hormone production, promote a healthy reproductive system, and contribute to brain health and mood regulation,” shares We Natal, a science-backed supplement brand focused on reproductive health. “Numerous studies have shown that omega-3 intake positively affects sperm quality, natural conception, and in vitro fertilization (IVF) outcomes [and] omega-3s during pregnancy supports the healthy growth and development of the baby. These essential fatty acids are crucial for optimal eye and brain development in infants.”
But, first: What even are DHA, EPA, and Omega-3s?
DHA and EPA are both omega-3 fatty acids. Most supplements contain a mix of the two, though each has different benefits:
- DHA (docosahexaenoic acid) is an omega-3 fatty acid found in fish and algae. It is essential for heart, brain, and eye health; it helps with memory, learning, and vision.
- EPA (eicosapentaenoic acid) is an omega-3 fatty acid found mainly in fatty fish (mackerel, sardines, salmon). It’s loved for its cardiovascular health benefits, including lowering blood pressure, inflammation, and triglycerides. It can also help reduce depression and regulate mood.
How much omega-3 should you take per day?
As for how much omega-3 you should take daily, general guidelines suggest that adults should aim for at least 250-500 milligrams of combined EPA and DHA per day for overall health, according to the National Institutes of Health (NIH). These numbers may increase or decrease depending on age and any specific health concerns or pregnancy, so talk to your doctor before adding a supplement to your routine. This is especially important if you are on other medications or supplements since omega-3s can interact with or affect your medication’s efficacy. Overall, you shouldn’t experience any negative side effects when adding fish oil to your diet — and if you do, talk with your healthcare provider! While you may notice fishy breath, we’ve done our best to find supplements that minimize any fish burps or nasty aftertastes.

Prices Starting At | $30/month supply
Topping our list is the LA-based and woman-led brand WeNatal, a longtime favorite with our editors for prenatal supplements for both him and her. When the WeNatal team announced they were coming out with an omega-3 supplement, we were so excited! And after having the chance to personally test this one, our editors can confidently put it at the top of our list.
WeNatal’s Omega DHA+ Fish Oil offers a premium formula with an impressive 830mg of mixed omega fatty acids, including a potent 600mg dose of DHA.

2. Ritual
Best For | Bioavailability
Active Ingredients | DHA (308 mg), EPA (154 mg)
Prices Starting At | $26/month
Say hello to another editor favorite! Ritual is also based in sunny LA (hi, neighbors!), and we’ve long loved the brand for its affordable and science-backed prenatal and synbiotic for gut heath. The omega-3 DHA & EPA is perfect for vegans or those who prefer a non-fishy “fish oil” option. Instead, the brand uses microalgae from Elantria algae oils, which is an eco-friendly, sustainable, and plant-based solution for omega-3s. The total dose is 500 mg with a 2:1 ratio of DHA and EPA, and the formula is third-party tested. We love the natural citrus addition for optimal freshness — no fish burps, guaranteed!
Customer Review | “I love it because I don’t like seafood or the fishy omega-3s so this one is perfect for me” – Reem (Read more reviews.)
3. FullWell
Best For | RD-formulated with rigorous testing
Active Ingredients | fish oil, DHA (500 mg), EPA (100 mg)
Prices Starting At | $27/month supply
FullWell’s RD-formulated and OBGYN-recommended fish oil supplement stands out for a few reasons. First, the formula includes 500mg of DHA and 100mg of EPA per serving. Second, the fish oil is sustainably sourced & Friend of the Sea Certified. We also love that FullWell ensures third-party testing for heavy metals, dioxins, and polychlorinated biphenyls (PCBs), which exceeds current standards in the industry. You can even see testing results for the most recent lot here. As for a fishy taste: These easy-to-swallow gel capsules encompass the fish oil to make it odorless and flavorless going down. We love that they have subscription options and HSA/FSA availability, too!
Customer Review | “My favorite fish oil. I’m really picky with supplements as a nutrition scientist, and these are everything I’m looking for to take daily.” – Michelle (Read more reviews.)
4. Future Kind+
Best For | Affordable
Active Ingredients | Algal oil, omega-6 fatty acids, omega-3 fatty acids (275 mg of combined DHA and EPA)
Prices Starting At | $27/two-month supply
Winning the spot for the most affordable option on our list, Future Kind+’s vegan omega-3 comes in a 2-month supply bottle. How’s that for a bang for your buck! The brand uses sustainably sourced vegan Omega-3 made from algae packed with EPA & DHA. The formula is carrageenan-free, and we love how easy to swallow the tiny soft gels are. They even include a natural orange aroma (no fish burps!) and come in a pretty glass bottle. As for certifications, the brand has third party testing right on its site so you can see the results for yourself. We love the transparency and affordability of this brand!
Customer Review | “Better for the planet and better for me. A clean, healthy source of omega-3 that doesn’t have the toxicity or “fish-burp” of piscine omega. It’s easy to take and I have noticed my mind seeming clearer. I’m a fan!” – Linda (Read more reviews.)
5. Calgee
Best For | Plant-based packaging
Active Ingredients | Algal oil, omega-6 fatty acids, omega-3 fatty acids (450 mg of combined DHA and EPA)
Prices Starting At | $24/month
I’m not sure what we love more about Calgee — the vegan omega-3s made from US-grown algae or the cute little (plant-based plastic!) pouches these supplements are packaged in. Calgee is passionate about promoting the health and environmental benefits of algae omega-3s, like how they are carrageenan-free and have a high concentration of DHA and EPA. The brand also has impressive backing for certifications, including Climate Neutral Certified, third-party lab testing, and 1% For the Planet. And guess what? The monthly subscription is one of the most affordable options on this list!
Customer Review | “I started taking vegan Calgee because I hate fish and did not want to taste it in a pill, and there was no aftertaste! In three months of daily use my omega levels were normal. Six months later my good cholesterol jumped 30 points. I’m thrilled with the results and will keep taking this supplement forever!” – Jennifer (Read more reviews.)
6. ÖRLÖ
Best For | Sleek and sustainable packaging
Active Ingredients | Algae oil, omega-3 fatty acids (260 mg of combined DHA and EPA), polar lipids
Prices Starting At | $38/monthly supply
ÖRLÖ is another editor favorite. Our team has personally tested this supplement and can attest to its potency and non-fishy taste. ÖRLÖ’s omega-3 supplement is 3X more bioavailable than fish oil since the brand uses a technology-based aquaculture system to grow microalgae — that’s right, it’s plant-based! Using 100 percent renewable resources with zero hexanes, pesticides, or environmental toxins, ÖRLÖ has created a vegan omega-3 supplement that packs a punch with EPA and DHA. Other facts we love: ÖRLÖ is carbon-negative and uses a light-blocking refillable glass container to protect the capsules from sunlight. All refills come in a pouch made from post-consumer recycled plastics; even printing is done with algae-based ink. The packaging is so pretty that it makes us want to take our morning vitamins.
Customer Review | “Having been on Orlo for a month I can tell my overall health is improving. I appreciate the non fish content as I can take them in the morning or evening. A quality Omega that I will continue to use.” – Aaron (Read more reviews.)
7. Mindbodygreen
Best For | High potency
Active Ingredients | Purified fish oil, EPA (857 mg), DHA (643 mg), other omega-3s (214 mg)
Prices Starting At | $49/monthly supply
With a whopping 1500 mg of DHA and EPA in just two gel caps, we’d be remiss to leave out mindbodygreen’s omega-3 potency+ supplement. Not only does this supplement have one of the highest potency levels on our list, but it’s also sustainably sourced. The company uses pure anchovy oil from wild-caught, cold-water pelagic fish from the South Pacific, and the premiere quality oil has achieved third-party ORIVO certification. Mindbodygreen’s omega-3 supplement is also third-party tested and GMO free. We love the addition of citrus and rosemary for botanical freshness (and to hide the fish taste!).
Customer Review | “High quality, easy to swallow, like the touch of lemon oil to avoid any bad taste. I had an omega lab check and all my levels/ratios were optimal thanks to this supplement! Definitely recommend.” – Kaitlin (Read more reviews.)
8. Thorne
Best For | Blends and options for kids
Active Ingredients | DHA (650 mg), EPA (200 mg)
Prices Starting At | $28/monthly supply
For a range of omega-3 supplements, we look no further than Thorne. The company has a longstanding reputation as a top dog in the supplement game, so it’s no surprise the brand offers a few options, including a prenatal DHA, an omega-3 with CoQ10, and even a liquid omega-3 supplement for kids (don’t worry; it’s sweetened!). Our recommendation for starting out is the Advanced DHA, as it’s more affordable and similar to other options on the list. One difference is it also includes an antioxidant blend with Vitamin E, so that’s a bonus! Thorne also tests for more than 250 environmental contaminants, including heavy metals, pesticides, dioxins, and PCBs — so you can trust that this brand is sustainable and safe.
Customer Review | “Love everything about these omegas! Outside of the obvious benefits, the gelcaps are not gigantic like so many other versions I have seen. You only need to take them once a day and they aren’t fishy at all! A huge plus!” – Melissa (Read more reviews.)
9. Needed
Best For | Prenatal
Active Ingredients | Non-vegan formula: fish oil, DHA (1000 mg) and EPA (100 mg); Vegan formula: DHA (400 mg), EPA (100 mg), lutein, zeaxanthin, and choline

Whether you’re trying to conceive or are pregnant, Needed’s prenatal omega-3 has the optimal ingredients to support you and your baby during this next season. This high potency dose of 1000mg DHA and 1000mg EPA supports egg quality, maternal mood, and baby’s optimal brain, nerve, and eye development.

Needed’s omega-3 is Clean Lable Project Certified, Certified Pesticide Free, and Friend of the Sea Certified. Oh, and it’s made in the USA at an FDA, GMP, and QAI Certified Organic facility and is third-party tested. Best of all, no fish burps! This sustainably sourced fish oil is encased in a gelatin-free, plant-based shell designed specifically to avoid unpleasant taste and smell.
Customer Review | “This is an amazing product! So easy to take, I take two pills in the morning and two in the evening so it’s not too much at once. So many Omega 3 pills I’ve taken in the past have a fishy taste, smell and terrible aftertaste, these DO NOT! Highly recommend.” – Hillary (Read more reviews.)
10. Perelel
Best For | No-nausea for expecting moms
Active Ingredients | DHA (250 mg), EPA (100 mg), other fatty acids (25 mg)
Prices Starting At | $26/month
Perelel’s Omega DHA + EPA fish oil is formulated by a team of leading OB/GYNs, which we love! We’ve been fans of this brand for a long time, and our editors have had a chance to talk with the team and try out the prenatals. It’s an excellent woman-founded brand creating supplements with top ingredients! This one, for example, uses sustainably sourced wild-caught fish oil to support your heart health, mood, and healthy fetal brain development throughout pregnancy. It’s recommended specifically for pregnant women looking for a daily omega-3 supplement, and the brand recommends pairing with the 1st Trimester Prenatal Powder. The No-Nausea Formulation is an added bonus, especially if you’re experiencing morning sickness.
Customer Review | “I’m obsessed with this company. I was taking first trimester prenatals until I miscarried and am now taking the conception pack post miscarriage. Just have to brag on the way they send me a hand written note from the co-founders sending me love for the loss of our baby. Will never use any other company!!!!” – Sarah (Read more reviews.)
