L-Proline delivers the amino acid proline in a free-form, highly absorbable version. The body uses proline as a core building block for collagen, which helps maintain the structure of skin, joints, and connective tissue. Its isolated form makes it a direct option for supporting collagen synthesis and connective tissue repair.
People take L-Proline to promote joint health and skin elasticity. Combining it with Vitamin C, Glycine, and Lysine can amplify collagen production. Athletes and active individuals also use it during recovery from exercise or injury to aid tendon and ligament health.
Taking L-Proline on an empty stomach improves absorption, though some prefer to take it with food to avoid stomach upset. Common doses fall between 500 mg and 2 g, depending on individual requirements and the specific formula.
