Most fish oil supplements are oxidized, under-dosed, or both. The omega-3 market is massive, but finding a product with meaningful EPA/DHA levels that isn't rancid by the time it reaches your cabinet requires knowing what to look for — and most brands hope you don't.
We evaluated 10 omega-3 supplements over 6 weeks, testing for EPA/DHA content per serving, TOTOX (total oxidation) values, heavy metal contamination, triglyceride vs ethyl ester form, and sustainability certifications. Products were blind-tested for freshness indicators including taste, smell, and burp-back.

FREQUENTLY ASKED
The American Heart Association recommends 1000mg of combined EPA+DHA daily for cardiovascular benefits. For anti-inflammatory and mood support, 2000–3000mg daily is supported by research.
Fish oil provides both EPA and DHA in higher ratios. Algae oil is the best plant-based alternative and provides DHA directly, but typically has less EPA. Choose algae if you're vegan or want sustainability.
Cut open a softgel and smell it. Fresh fish oil smells mildly oceanic, not strongly fishy. If it smells bad, it's oxidized and potentially harmful. Also check the TOTOX value on the brand's certificate of analysis.
Always. Omega-3s are fat-soluble and absorb significantly better when taken with a meal containing dietary fat. This also reduces the chance of fishy burps.
Yes. EPA in particular has anti-inflammatory properties that can ease PMS symptoms, and DHA supports brain health during hormonal fluctuations. Studies show benefits for mood, skin, and menstrual comfort.
