Valine (l-)

Product code: P2202

• One of the 3 major Branched-Chain Amino Acids (BCAA) . . .the other 2 being Leucine and Isoleucine . . . all of which are involved with muscle strength, endurance, and muscle stamina.
• BCAA levels are significantly decreased by insulin. High dietary sugar or glucose intake causes release of insulin, which, in turn, causes a drop in BCAA levels.
• Competes with Tyrosine and Tryptophan in crossing the blood-brain barrier. The higher the Valine level, the lower the brain levels of Tyrosine and Tryptophan. One of the implications of this competition is that Tyrosine and Tryptophan nutritional supplements need to be taken at least an hour before or after meals or supplements that are high in branched chain amino acids.
• Actively absorbed and used directly by muscle as an energy source.
• Not processed by the liver before entering the blood stream.
• Any acute physical stress (including surgery, sepsis, fever, trauma, starvation) requires higher amounts of Valine, Leucine and Isoleucine that any of the other amino acids.
• During period of Valine deficiency, all of the other amino acids (and protein) are less well absorbed by the GI tract.
