Ingredient Information: Hydroxyproline is an amino acid derivative naturally found in collagen, produced by post-translational hydroxylation of proline by prolyl hydroxylase in the presence of vitamin C, or synthesized industrially via microbial fermentation or chemical modification of proline. Composed of carbon, hydrogen, nitrogen, and oxygen, it features a pyrrolidine ring with a hydroxyl group at the 4-position, enhancing collagen stability. It is processed into a stable, water-soluble powder (solubility ~1000 g/L at 20°C), widely used in nutritional and research applications.

Uses: Widely used in dietary supplements to support collagen synthesis, promoting joint, skin, and connective tissue health, often dosed at 500-1000 mg/day in combination with collagen peptides, with studies showing improved skin elasticity after
