Description
Omega-3 Fish Oil — one of the most researched supplements in existence, with over 30,000 published studies on EPA and DHA.
The two active omega-3 fatty acids are EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). ALA from plant sources (flaxseed, chia) converts to EPA and DHA at less than 5% efficiency in most adults — making direct supplementation the most reliable way to maintain adequate omega-3 status.*
DHA is the primary structural fatty acid in brain tissue — comprising approximately 30–40% of total fatty acids in the cerebral cortex. Research supports DHA’s role in cognitive function, visual acuity, and neural membrane integrity.* EPA is the primary omega-3 involved in cardiovascular health markers and inflammatory pathway modulation.*
What separates quality fish oil from commodity products: the EPA:DHA ratio, the triglyceride vs. ethyl ester form, and third-party testing for heavy metals and oxidation. Our lot-specific COA documents heavy metal testing results for every batch.
Every lot independently third-party HPLC tested including heavy metals panel. Lot-specific COA at oligopolypeptides.com/certificates/.
