L-Valine is an essential branched-chain amino acid (BCAA) your body uses for muscle protein synthesis and tissue repair. This micronized version has a smaller particle size, so it mixes more easily in liquids and can be absorbed faster.
Taking it before, during, or after training helps support workout recovery, eases muscle soreness that follows exercise, and helps hold on to lean mass when calories are low. Many people stack it with other BCAAs.
Check with a professional before use if your kidneys or liver don't work normally.
