L-valine, along with L-leucine and L-isoleucine, is one of the branched-chain amino acids (BCAAs). It plays a vital role in promoting healthy growth in infants and children, supplying energy during physical activity, and maintaining nitrogen balance in adults.
It is important to emphasize that L-valine is an essential amino acid, meaning the human body cannot produce it and it must be obtained through the diet. On average, adults require approximately 0.7 grams per day.
The incorporation of L-valine in cosmetics can enhance their moisturizing properties and support collagen synthesis. It is one of the amino acids that make up the skin’s natural moisturizing factor (NMF), which helps maintain proper hydration and protect the outer layer of the skin.
