Our Selection Criteria
Rancid fish oil delivers oxidized lipids that damage health. We require products with third-party IFOS 5-star certification or published TOTOX scores below 5.
Research shows 1000mg+ daily of combined EPA + DHA for meaningful cardiovascular and cognitive benefits. Lower doses require unsustainable serving sizes.
Wild fish omega-3s deplete ocean stocks. We prioritize products certified by Marine Stewardship Council or Friend of the Sea, or vegan algae-based alternatives.
Fish bioaccumulate heavy metals and PCBs. Molecular distillation removes contaminants while preserving EPA/DHA potency. Non-negotiable for our picks.
