- It is important to distinguish between two categories that UK researchers commonly confuse:
- Dietary collagen peptides — Hydrolysed proteins sold as supplements (powder, capsule). These are food-grade products, well-studied, with a strong safety profile. Primary routes of use are oral. They support the body’s collagen production indirectly through fibroblast stimulation and amino acid provision.
- Research peptides with collagen-modulating mechanisms — Synthetic or bio-identical peptides such as GHK-Cu (copper tripeptide), BPC-157, and TB-500 that influence collagen synthesis through specific receptor or enzyme pathways. These are distinct from food supplements and are subject to different regulatory considerations in the UK.
- For UK researchers interested in collagen biology, both categories offer distinct investigative value. GHK-Cu, for example, has been shown to upregulate expression of 31 genes related to collagen synthesis and remodelling, acting far more precisely than broad-spectrum hydrolysed collagen supplementation.
