L-Valine is an essential amino acid, meaning that it is not able to be biosynthesized in the human body. It must therefore be obtained through dietary sources, primarily meat. Dairy products are also high in L-Valine, especially cottage cheese. Vegetable sources of L-Valine include cereal grains, mushrooms, peanuts and soybeans. The minimum daily requirement of L-Valine is 10 milligrams per kilogram of body weight for adult males.

Athletes such as bodybuilders and runners may also need additional L-Valine as a result of their frequent, vigorous exercise. The most significant sign of an L-Valine deficiency is weight loss, especially muscle mass. Conditions of the nervous system can also mean that L-Valine can help you due to its role in forming the myelin sheaths that cover nerve cells.
