Valine is an essential amino acid necessary for the smooth functioning of the nervous system. It is one of the three Branch-Chained Amino Acids (BCAAs) along with leucine and isoleucine.
Since it cannot be produced naturally by the body, it must be obtained from reliable food sources and supplements. As an essential amino acid, it is vital for everyday body functions, muscle maintenance and immune system regulation. Key sources include leafy vegetables, kidney beans and milk.
As a natural supplement, valine is used together with leucine and isoleucine to promote muscle growth. Valine also provides energy and helps repair damaged tissues brought about by intense physical activity. It is necessary for muscle metabolism and growth of muscle tissue.
Valine also helps to maintain the ideal amounts of nitrogen in the body. As a BCAA, it can be used as an energy source in the muscles, preserving glucose use in the process. It is ideally suited for endurance athletes who are involved in sports such as long-distance running and bodybuilding.
Other notable benefits of valine include its ability to improve insomnia and anxiety. Some studies also suggest its use as an appetite suppressant and an immune system regulator.
The recommended daily dosage of valine is 25-65 milligrams per pound of body weight. It is recommended that supplemental valine be used in union with both isoleucine and leucine.
