BCAAs stands for branched-chain amino acids. Of the 9 essential amino acids, 3 are branched-chain amino acids: leucine, isoleucine, and valine.
BCAAs are essential nutrients needed for many biological processes that happen within our bodies, most notably, building and repairing muscles and tissue. Other functions include giving cells their structure, transporting and storing nutrients, as well as forming our organs, glands, arteries and muscles.
Our bodies can’t produce BCAAs internally, so they have to be obtained from the foods that we eat. BCAAs - leucine, isoleucine, and valine - are amino acids that have aliphatic side-chains with a branch in their atomic structure. Branched-Chain Amino Acids account for 35% of the essential amino acids in our muscles, and they are needed for optimal muscle growth and repair.
BCAA supplements are generally safe if a person follows the manufacturer’s instructions and does not exceed the maximum stated dosage. However, anyone who experiences serious side effects should stop taking the supplement and consult their doctor.
