Why supplement?
Marked asPrimarySupporting
Supports wound and skin repair
Collagen α chains repeat a glycine-proline-hydroxyproline motif; proline's pyrrolidine ring lets the triple helix bend and stay stable, and hydroxylation needs vitamin C. Demand for it rises when wounds, tendon, and skin are repairing; broths of skin, sinew, and trotters are also often used to supply this kind of raw material.
Maintains connective-tissue strength
Fibroblasts take up large amounts of proline when they make collagen; cells can also use it as an osmoprotectant. For people whose tendons tighten after long standing or who are in a skin-repair phase, connective-tissue foods such as skin, sinew, and trotters release large amounts of proline after hydrolysis for collagen to use.
Which symptoms may ease?
Wrinkles
Collagen α chains repeat a glycine-proline-hydroxyproline motif; proline's pyrrolidine ring lets the triple helix bend and stay stable, and hydroxylation needs vitamin C. People whose eye-area lines deepen and whose skin loses bounce more often notice firmness and shallower fine lines after several continuous weeks.
Joint pain
Collagen α chains repeat a glycine-proline-hydroxyproline motif; proline's pyrrolidine ring lets the triple helix bend and stay stable, and hydroxylation needs vitamin C. People whose knees tighten on stairs and whose joints are stiff on waking more often notice easier movement and a shorter stiff period after several continuous weeks.
Which conditions may it support?
Osteoarthritis
Collagen α chains repeat a glycine-proline-hydroxyproline motif; proline's pyrrolidine ring lets the triple helix bend and stay stable, and hydroxylation needs vitamin C. People whose load-bearing joints hurt and creak in motion more often notice walking comfort and stiff time after several continuous weeks.
How to take it?
After continued use, reassess by how you feel and whether you still need it.
How oftenUsually fine to use daily; adjust to personal need.
