BCAA 1000 Caps contain a potent balance of Branched Chain Amino Acids which are building blocks of muscle mass and size. Metabolized directly in the muscle, BCAAs may improve nitrogen retention by sparing other amino acid groups for repair and rebuilding.

BCAAs, or branched chain amino acids, have long been used by strength-training and endurance athletes alike to activate muscle synthesis and reduce muscle breakdown caused by intense training. Optimum Nutrition's Instantized BCAA 1000 is made using a proprietary process that mixes easily and keeps the BCAAs suspended longer so they do not readily settle to the bottom of the glass.

Optimum Nutrition's BCAA 1000 provides a blend of the three Branched Chain Amino Acids (L-Valine, L-Leucine and L-Isoleucine) in every serving. The Branched Chain Amino Acids (BCAA's), so named because of their unique branched chemical structure, are essential in that the body cannot make them from other compounds. In recent times, these amino acids have been investigated for their potential anticatabolic (preventing muscle breakdown) and anabolic (muscle building) effects.
