Summary
Collagen peptides are short-chain amino acid sequences produced by enzymatic hydrolysis of whole collagen (typically bovine or marine). They serve as bioactive signals that stimulate fibroblasts and chondrocytes to produce new collagen, elastin, and cartilage matrix, supporting skin, joint, bone, and gut health.
Oxytocin is a 9-amino acid neuropeptide produced in the hypothalamus with diverse roles in social bonding, trust, stress reduction, and sexual function. Exogenous administration is used therapeutically to improve social cognition, reduce anxiety, and enhance intimacy.
