L-Proline is a non-essential amino acid that plays a central role in the synthesis of collagen, the most abundant structural protein in the body. Research suggests that proline, along with its derivative hydroxyproline, is critical for maintaining the stability and integrity of collagen fibers, which support skin elasticity, joint cartilage, tendons, and blood vessel walls. Studies indicate that adequate proline availability may contribute to wound healing processes and the ongoing repair of connective tissues, with some research exploring its potential role in supporting cardiovascular health by helping maintain arterial integrity. While the body can produce proline on its own, interest has grown in supplemental L-proline for individuals looking to further support collagen-dependent tissues, particularly in the context of aging, recovery, or increased physical demand.
