NOW Foods L-Proline – 500mg, 120 Capsules | Skin & Joint Support

Proline is one of the two amino acids that make up most of the collagen molecule — collagen is roughly a quarter proline and glycine. The body can make it, but people supplement it alongside vitamin C when they are working on skin, joints or connective tissue, since vitamin C is required for the step that stabilises the collagen fibre.

Why people take it

• A primary building block of collagen
• Taken for skin, joint and connective-tissue support
• Works alongside vitamin C, which collagen synthesis requires
