2.5 g L-Leucine 1.25 g L-Isoleucine 1.25 g L-Valine 60 Servings 5 g Branched Chain Amino Acid Supplement True Strength The True Strength 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 support protein synthesis and recovery from intense training. Our Instantized BCAA 5000 Powder 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. Because if you can't drink your BCAAs, they can't help your performance.
