L-valine

Valine is one of twenties amino acids in human body which compose protein, and also one of 8 kinds of amino acid and glycogenic amino acid. It works with other two kinds of high concentration amino acid (isoleucine and leucine) to improve normal body growth, repair tissue, adjust blood glucose and provide with important energy. When a human performs any strenuous physical activities, valine can provide body with additional energy to form glucose and prevent muscle asthenia. It also helps to remove redundant nitrogen (potential toxin) from liver and transform the nitrogen required by body to any parts.
