Helps improve the appearance of wrinkles (when used together with glycine and proline).
Leucine is an essential amino acid that our bodies cannot produce on their own, making it crucial to obtain through our diet or supplements. Just like isoleucine, leucine is involved in collagen production, the protein responsible for maintaining skin elasticity and firmness. Leucine also plays a role in maintaining the skin’s barrier function. It helps to strengthen the outermost layer of the skin, known as the stratum corneum, which acts as a protective barrier against environmental stressors. Additionally, leucine has been found to aid in the wound healing process. It supports the formation of new blood vessels, accelerates tissue regeneration, and promotes the synthesis of collagen at the wound site. [1]
