L-Proline

L-Proline is a non-essential amino acid that plays a vital role in collagen formation and connective tissue repair. It contributes to joint, skin, and tendon health — factors important for active individuals and those engaging in high-impact sports.

Proline is essential for maintaining structural integrity in muscles and joints, especially during recovery from exercise-induced stress. It also supports wound healing and tissue regeneration.

Though not commonly used as a standalone supplement, it is valued in collagen-based products and recovery formulas for athletes.
