Collagen Peptides

Collagen peptides are small chains of amino acids derived from collagen, the main structural protein found in animal connective tissues. They are produced by hydrolysing collagen, a process that breaks down the protein into smaller, more easily digestible fragments. This processing makes them soluble in cold water and readily absorbed by the body.

Collagen peptides are often added to foods and drinks for their protein content and perceived health benefits, particularly for skin, hair, nails, and joints. They are commonly found in supplements, protein bars, and fortified beverages, where they contribute to the overall protein profile without significantly altering flavour or texture.

Collagen peptides are not classified as a food additive in the UK and do not have an E-number. They are considered a source of protein. While some studies suggest potential benefits for joint health and skin hydration, the scientific evidence is still developing and mixed. The World Health Organization's International Agency for Research on Cancer (IARC) has not classified collagen peptides. Regulatory bodies like EFSA have evaluated collagen as a food ingredient, but specific health claims require robust scientific substantiation.
