Valine is one of the amino acids which the body cannot for manufacture itself
but must acquire from food sources. 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. A deficiency may affect
the myelin covering of the nerves. Recent studies indicate that valine, as well as leucine
and isoleucine, may be effective in treating or reversing hepatic encephalopathy, or
alcohol related brain damage. It may also be useful in degenerative neurological
conditions. Main food sources of valine are soy flour, raw brown rice, cottage cheese,
fish, beef, lamb, chicken, almonds, brazil nuts cashews, peanuts, sesame seed, lentils,
chickpeas and mushrooms.
