Hydrolyzed collagen

Hydrolyzed collagen, also known as collagen peptides, is a protein derived from collagen, which is abundant in animal connective tissues like skin, bones, and cartilage. It is produced by breaking down collagen into smaller protein fragments through a process called hydrolysis, typically using enzymes or acids.

Manufacturers add hydrolyzed collagen primarily for its protein content and perceived benefits for skin, hair, nails, and joints. It functions as a protein source and is often incorporated into functional foods and supplements such as protein bars, powders, and beverages.

Hydrolyzed collagen is not currently listed as an authorised food additive on the Register of Food Additive Authorisations in Great Britain. Therefore, it is typically used as a food ingredient rather than an additive. Some studies suggest potential benefits for joint health and skin hydration, but robust, peer-reviewed evidence is still developing, and more research is needed to confirm these effects.
