L-Hydroxyproline

L-Hydroxyproline (trans-4-hydroxy-L-proline) is a non-essential amino acid formed from L-proline after the proline has been built into collagen, of which it is one of the main constituent amino acids. Nustras supplies it as a white crystalline powder of non-animal (vegan) origin, used as an ingredient in supplements, cosmetics and specialised nutrition.

It is formulated into amino acid and collagen-category supplements, capsules and tablets, drink powders and functional beverages, cosmetic and skin-care formulations where it is used as a conditioning ingredient, and in cell-culture media and research reagents. It is also used as a flavour-related ingredient in some food applications.

The material is a white crystalline powder, soluble in water (CAS 51-35-4, C5H9NO3, molecular weight 131.13). Assay is standardised to specification and confirmed by titration or HPLC on each lot, with identity confirmed by infrared spectroscopy and specific rotation. Heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies L-hydroxyproline in bulk commercial quantities, in food-grade bags and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. L-Hydroxyproline is an accepted supplement and cosmetic ingredient in major markets; buyers confirm the permitted level and claim for their application.
