L-Valine is an essential amino acid and, along with L-Leucine and L-Isoleucine, is part of the branched chain of amino acids. The body cannot manufacture L-Valine, so it must be acquired via diet or supplementation. The male adult’s daily requirement is 10 mg per kg of body weight.
- L-Valine is found in grains, dairy products (especially cottage cheese), mushrooms, meats, peanuts and soy proteins. Supplemental L-Valine should always be combined with the L-Isoleucine and L-Leucine.
- L-valine is a branched chain amino acid (as are L-Isoleucine and L-Leucine), which is important for supplying energy to muscles. The branched chain amino acids enhance energy, increase endurance and aid in muscle tissue recovery and repair.
- As a branched chain amino acid, L-valine is important for optimal growth in infants and children and nitrogen balance in adults.
- Branched chain preparations are used in sports nutrition and health foods.
