What Collagen peptides is

The largest consumer peptide market there is, resting on trials that almost never compare it against the one thing that would settle the question: an equal dose of ordinary protein.

Collagen peptides are collagen broken into short fragments so they survive digestion better. The skin and joint trials are numerous and many are positive.

Mechanism: Proposed: collagen-derived peptides survive digestion, reach skin and cartilage, and signal fibroblasts and chondrocytes to increase matrix production. Demonstrated: collagen provides glycine, proline and hydroxyproline.

Regulatory history: Sold as a dietary supplement. No approved therapeutic indication.

How MHRA treats this kind of product

Licenses medicines for the UK market. A compound without a marketing authorisation is an unlicensed medicine, which can only lawfully be supplied for human use through a prescriber under the specials scheme, not sold as a research product.

The classification above is the The Longevity Archive reading of Medicines and Healthcare products Regulatory Agency listings for Collagen peptides at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
