BCAAs (Branched-Chain Amino Acids) are essential nutrients—Leucine, Isoleucine, and Valine—that support muscle growth, reduce fatigue, and speed up recovery. Popular among athletes and fitness enthusiasts, BCAA supplements help prevent muscle breakdown during intense training, improve endurance, and enhance workout performance. Available in powders, capsules, and flavored drinks, BCAAs are a convenient way to fuel muscles, boost strength, and promote lean muscle retention.
