Best Omega 3 Supplement: Price per Gram of EPA + DHA

Omega-3 fats from fish are popular, but big trials have been disappointing for general heart health. The clearest effect is on triglycerides, a type of blood fat, and higher doses have been linked to a higher chance of an irregular heartbeat called atrial fibrillation. We rate the evidence C, and oily fish is a simpler place to start. If you still want a supplement, this page compares fish oil by the part that matters: EPA plus DHA. See the omega-3 guide first.

Short answer: Best overall (US$): Thorne Super EPA; Best tested (US$): Momentous Omega-3; Best budget (UK £): Bulk Omega 3 Fish Oil. Prices, testing and every shop are in the picks below.

How we rank

We only rank products that are in our product data file, and we use only what that file records:

1. Form and amount. We compare EPA plus DHA per serving, not the total weight of fish oil, because that is the part trials study.
2. Third-party testing, as listed. We note a named testing program (for example NSF Certified for Sport) when our data lists one. Where the data says “brand statement”, we say so and do not count it as verified by us.
3. Price per daily dose. We divide the pack price by the servings per pack, then scale to our basis: 1 g of EPA plus DHA a day, the amount used in the VITAL trial on our omega-3 guide. It is a study amount, not a recommendation. Prices in different currencies are not converted, so $ and £ are only compared within their own currency.

Winner labels. “Best overall” goes to the cheapest product with a named testing program in that currency. “Best budget” goes to the lowest price per daily dose in that currency, whatever the testing. “Best tested” is only used when one product lists clearly more named programs than the rest. If no product qualifies for a label, we leave that label out.

Freshness. Our data has no freshness or oxidation test results for any product, so we cannot rank on freshness.

What we did not do. We have not tested these products ourselves, in a lab or by taking them. We did not rank by commission. Prices change, so each price shows the date it was checked. More in How we rank.

Price per daily dose

Basis: 1 g of EPA plus DHA a day, the amount used in the VITAL trial on our omega-3 guide. It is a study amount, not a recommendation. Every number below is worked out from the pack price, servings per pack and amount per serving in our product data.

US dollar prices ($)

Product (retailer)	Amount per serving	Pack price (checked)	Price per serving	Price per daily dose	Testing named in our data
Thorne Super EPA, 90 gelcaps (Thorne)	1 gelcap: 425 mg EPA + 270 mg DHA	$45.00 (Nov 1, 2026)	$45.00 ÷ 90 = $0.500	$0.500 × 1 ÷ 0.695 = $0.719	NSF Certified for Sport
Momentous Omega-3, 60 capsules (Momentous)	2 capsules: 1,600 mg EPA + DHA	$39.99 (Nov 1, 2026)	$39.99 ÷ 30 = $1.33	$1.33 × 1 ÷ 1.6 = $0.833	NSF Certified for Sport; IFOS Certified

UK prices (£)

Product (retailer)	Amount per serving	Pack price (checked)	Price per serving	Price per daily dose	Testing named in our data
Bulk Omega 3 Fish Oil Softgels, 90 softgels (Bulk)	4 softgels: 720 mg EPA + 480 mg DHA	£7.99 (Nov 1, 2026)	£7.99 ÷ 22 = £0.363	£0.363 × 1 ÷ 1.2 = £0.303	None named

Bulk’s pack has 90 softgels at 4 a serving, which is 22.5 servings; our data records 22, so the table uses 22. At 22.5 the price would be £0.296 per gram.

Nordic Naturals has no verified price in our data, so it is not in the table.

How to start

Large trials used about 1 g of omega-3 a day, and prescription products used 4 g a day. Those are study amounts, not recommendations. Check EPA plus DHA on every label. If you eat oily fish, you may not need a supplement. The omega-3 guide covers food first, the official intake figures and algae oil for people who avoid fish.

Talk to your doctor or pharmacist

Talk to your doctor or pharmacist before you start any supplement, especially if you are pregnant or breastfeeding, take prescription medicine, or have a health condition. Ask first if you take blood thinners such as warfarin, have a bleeding disorder, have an irregular heartbeat or a fish or shellfish allergy. The full guide has the evidence, safety notes and citations.
