We start with the freshest fish oil available and add Lemon Essential Oil. That's how we deliver no fishy aftertaste, just a lemony fresh flavor.This unique fish oil is sourced from Walleye Pollock caught wild in Alaskan waters. Upon catch, our fish is immediately placed in refrigerated sea water tanks. The oil is extracted within 24 hours to ensure maximum freshness, then pressed and purified by a family-owned American company using advanced processing technology.
