What is Collagen Peptides?

Collagen is the most abundant protein in the human body, the structural scaffolding of skin, joints, bones, tendons, and connective tissue. After age 25, the body's own collagen production declines about 1-2% per year, contributing to skin thinning, joint stiffness, and tissue fragility. Hydrolyzed collagen peptides (type I and III from grass-fed bovine, or type II from chicken) are broken into bioactive di- and tripeptides the body can use as both raw material and as signaling molecules to stimulate its own collagen production. Multiple randomized trials show benefits for skin elasticity and hydration, joint comfort, and nail strength. Standard dose is 10-20 g daily, mixed in coffee or smoothies.
