Buying criteria

Read EPA and DHA, not just the softgel size: The name on the front often shows a number such as 1,000 mg or 1,100 mg per softgel. The Supplement Facts panel lists the EPA and DHA amounts per serving, and the serving can be 1, 2 or 4 softgels. This page lists the labeled EPA and DHA for one serving of each product.
Check the serving size and bottle count: A 100-softgel bottle can be 25, 50 or 100 servings depending on the serving size. We list the labeled serving size and servings per container.
Shell material and source information: Softgel shells on these labels are fish gelatin, bovine gelatin or beef gelatin, or unspecified gelatin. Some labels also name the fish used. We copy the label wording and do not rank one source over another.
What %DV means: %DV is the percent daily value printed on the label. Some labels footnote that %DV is based on a 2,000 calorie diet; for EPA and DHA most labels print a dagger meaning a daily value has not been established.
How we picked and ordered the products: We took the front of the iHerb US Best Sellers list for fish oil, merged the same product sold in different counts, and kept at most 3 products per brand. The order on the page follows that list, not a quality ranking. We did not test any product.

FAQ

Is EPA plus DHA the same as total omega-3?

Not always. Several labels print a separate total omega-3 line that includes other omega-3 fatty acids; others list only EPA and DHA. Compare the lines the label actually prints.

Why do the prices per serving differ so much?

Serving sizes range from 1 to 4 softgels, and bottle counts range from 30 to 240. iHerb shows a per-serving price for each product; we copy it where shown.

Do these prices apply in my country?

No guarantee. The prices are iHerb US prices checked on 2026-11-04. Price, promotions, shipping and availability differ by country; check the iHerb checkout page.

Did you test these products?

No. We only read the Supplement Facts and other label information on the iHerb product pages and compare what is printed.

Can supplements replace medical care?

No. Supplements are not a substitute for medical care. If you are pregnant, nursing, taking medication or have a medical condition, ask a doctor or pharmacist before taking any supplement.
