NOW Foods L-Proline 500 mg provides this conditionally essential amino acid that is the most abundant amino acid in collagen and plays a critical structural role in connective tissue throughout the body. Proline is needed for the biosynthesis of collagen in skin, cartilage, tendons, blood vessels, and bone matrix, and its availability can become a limiting factor in collagen production especially during healing, recovery from injury, or times of elevated physical stress. Supplementing L-Proline alongside vitamin C supports optimal collagen cross-linking and connective tissue integrity.
