Standardized Form
Delivered naturally within Hydrolyzed Collagen Peptides

Hydroxyproline is an amino acid not directly synthesized by DNA; instead, the enzyme prolyl hydroxylase modifies proline into hydroxyproline (a process that strictly requires Vitamin C). It is found almost exclusively in collagen. In the context of supplementation, short dipeptides containing hydroxyproline are the highly bioactive molecules that cross the intestinal barrier, enter the bloodstream, and bind to receptors on fibroblasts to stimulate endogenous collagen production.

Clinical Summary

The most critical amino acid for collagen stability. Its presence in blood plasma after consuming collagen peptides is the primary physiological trigger for the body to initiate skin and joint tissue regeneration.

Dosage Guidelines

Supplied naturally within a standard 2.5g to 15g dose of collagen peptides.

Safety & Side Effects

Completely safe; acts as a natural breakdown product of human tissue remodeling.

Known Interactions

No known interactions.
