BCAA Capsules may help maintain mental clarity, promote muscle recovery, and enhance muscle growth while youare pushing your limits. BCAAs are branched-chain amino acids that help protect muscles from damage and help rebuild them. Each capsule delivers a 4:1:1 ratio of the three BCAAs (L-Leucine, L-Valine, and L-Isoleucine). As little as 1500mg can enhance muscle buildup and prevent muscle breakdown. You can take these anytime, however we recommend them primarily after exercise and especially on heavier training days.
