The collagen peptides are marine-based and derived primarily from the skins of fish, using both farmed and wild-caught species. The wild fish used are from non-endangered species to ensure sustainability, while farmed fish represent a renewable resource. The fish skins are by-products of the seafood industry, which aligns with Naticol’s circular economy and sustainability efforts. Naticol collagen is certified by the Friend of the Sea program, which verifies that it comes from environmentally responsible sources. The exact species of fish can vary, but Naticol ensures that all fish used meet strict environmental and quality standards.
