5 Overview
IFOS is THE gold standard for fish oil quality — testing potency (EPA/DHA content), purity (heavy metals, PCBs, dioxins), and critically, FRESHNESS (oxidation markers: peroxide value, anisidine value, TOTOX) [1]. Fish oil oxidation is a major quality issue — rancid fish oil may be harmful and is certainly ineffective. IFOS awards a 5-star rating system based on how far above WHO/GOED standards a product tests. Products with 5 stars exceed all international standards by a significant margin. IFOS is the only major certification program specifically designed for fish oil [1].
