980 mg^ L-Leucine 490 mg^ L-Isoleucine 490 mg^ L-Valine 100 Servings Branched Chain Amino Acid Supplement 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. Our Instantized BCAA 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. ^Per Serving
