Branched Chain Amino Acids (BCAA) are three essential amino acids; leucine, isoleucine and valine. Essential amino acids can’t be manufactured in the body so must come from the diet and supplements. The body uses BCAA to support the building of protein in the body and to support the health of the muscles. Note: This product is not intended to diagnose, treat, cure, or prevent any disease, nor should supplements be used as a substitute for a balanced diet. Not intended for pregnant/breastfeeding mothers or children under 18. Do not exceed the recommended dose.
