Isoleucine is an essential amino acid that along with leucine and valine makeup the "branched chain amino acids" (BCAA). This amino acid cannot be manufactured in the body, and needs to be supplied in the diet. Isoleucine is thought to play the biggest role in increasing endurance and helping heal, repair and grow muscle tissue damaged from injury and strenuous exercise and training. Isoleucine is especially important to serious athletes and body builders because of its role in boosting energy production and assisting the body recover from strenuous physical activity.

Isoleucine, together with the other two branched-chain-amino-acids promote muscle recovery after physical exercise and on its own it is needed for the formation of hemoglobin as well as assisting with regulation of blood sugar levels as well as energy levels. It is also involved in blood-clot formation.

         • An essential amino acid.
         • Required for muscle tissue maintenance.
         • Preserves muscle glycogen stores (energy).
         • Prevents muscle protein deterioration especially during exercise.
         • May be helpful for individuals who exercise in extreme conditions.
         • One of the Branched Chain Amino Acids (BCAA)
