Best Omega-3: The Buying Guide

EPA/DHA grams, IFOS-style testing, and the Amazon bottle we actually use

Omega-3 is a foundation supplement if you do not eat fatty fish twice a week. You want EPA+DHA in grams, not a 1,000mg ‘fish oil’ softgel that is mostly filler. This buying guide points at Nordic Naturals Ultimate Omega and tells you what to ignore.

Read the Label

Strong Evidence

A 1,000mg capsule can hide 180mg EPA and 120mg DHA. That is a seasoning. Nordic Naturals Ultimate Omega is a concentrated triglyceride-form default already on our roster.

Algae DHA is the vegan path. Cod liver oil is a different (vitamin A) product.

Dose

Moderate Evidence

Food-first: two fatty-fish meals. Capsules fill the gap. High-dose EPA for triglycerides is a clinician protocol (think icosapent ethyl), not two extra grocery softgels.
