PrimaGround Hydrolyzed Marine Collagen is sourced from a single MSC-certified North Atlantic cod cooperative we have visited and audited. The peptides are enzymatically hydrolyzed to a low molecular weight (≤ 3 kDa) so they dissolve cleanly and absorb without grit, foam, or fishy taste. Every lot is tested by two independent ISO-17025 labs for heavy metals, microbials, and amino-acid profile — the certificate of analysis for each lot is linked at the bottom of this page.
