L-Isoleucine is an essential amino acid. It can not be made by the body, and must be acquired through food or supplements. The male adult’s daily requirement is 10 mg/Kg body weight. Food sources for isoleucine including almonds, cashews and soy protein. It has numerous health and athletic performance benefits. L-Isoleucine is known as one of the three branched chain amino acids (BCAAs, L-isoleucine, L-valine, and L-leucine). It is used in combination with the L-leucine and L-valine to improve the nutritional status of people. The combination ratio is usually 2:1:1 (L-leucine : L-isoleucine : L-valine). BCAAs serve as important fuel sources for skeletal muscle during periods of metabolic stress. BCAAs may promote protein synthesis, suppress protein catabolism and serve as substrates for gluconeogenesis. BCAAs are catabolized in skeletal muscle, stimulating the production of L-alanine and L-glutamine, and other substances. Generally suggested dose for adults: To take 1 teaspoon of the powder (2 grams) with water or beverage 2 to 3 times daily. Or, adjust the use amount as advised by your physician.
