Valine is found in abundant quantities in most food. Valine has a stimulant effect.
Healthy growth depends on it.
A deficiency results in a negative hydrogen balance in the body. Valine is used by bodybuilders, in conjunction with leucine and isoleucine, for muscle growth, tissue repair and as an energizer. There is little scientific evidence to support these claims, though studies have shown that these three substances might be able to help restore muscle mass in people with liver disease, injuries, or who have undergone surgery, but no studies have shown them to be effective for healthy people. Because valine cannot be produced by the body, healthy people should ensure that they are obtaining at least the recommended amount in their diet. Valine can be metabolized to produce energy, which spares glucose.
