Amino acids and BCAA’s are often called the building blocks of protein, and the proteins and enzymes that make up these amino acids form muscles, hormones, neurotransmitters, and more that keep the body running smoothly. A healthy body needs twenty different amino acids, several of which are produced by the body itself. However, eight of these can only be obtained through diet or supplements, and many of the others often need a boost due to a variety of factors, including diet, age, exercise, infection and stress levels. Amino acid supplements can help make a body healthy and fight conditions like fatigue. They are especially useful for bodybuilders and powerlifters, as amino acids are important for building, maintaining and repairing muscle. For those taking supplements to help with strength training, BCAA supplements are a good choice. BCAA stands for branched chain amino acids, which includes leucine, isoleucine and valine – three of the amino acids your body can’t make on its own. Leucine, isoleucine, and valine make up about 33% of the body’s skeletal muscle and are essential for muscle formation and helpful in slowing muscle breakdown.
