5,000 mg Branched Chain Amino Acid Supplement. 2.5 g L-Leucine, 1.25 g L-Isoleucine, 1.25 g L-Valine, 60 Servings. The Bigger Picture of Branched Chain Amino Acids (BCAAs)-L-Leucine, L-Isoleucine, and L-Valine are commonly grouped together and referred to as Branched Chain Amino Acids, or BCAAs, because of their unique branched chemical structure. (BCAAs) are essential, meaning that they must be consumed through the diet, since the human body cannot make them from other compounds. BCAAs have long been used by strength-training and endurance athletes alike to activate muscle synthesis and reduce muscle breakdown caused by intense training. Our Instantnized BCAA 5000 Powder is made using a proprietary process that mixes easily and keeps the BCAAs suspended longer so that they do not readily settle to the bottom of the glass. Because if you can't drink your BCAAs, they can't help your performance. Contents sold by weight not volume.
