The Bottom Line
Overall, the evidence shows BCAA supplements fall well short of their marketing hype. There are studies showing BCAAs improved some measures, unfortunately, the practical benefits of using this supplement are lacking.
If you are already using a protein supplement, check the label. Chances are, it includes additional BCAAs and you are already seeing any benefits from supplementation. Adding extra is unlikely to yield any further results. Many protein supplements include 4 or more grams of BCAAs. For the vast majority of protein supplement users, more BCAAs will not likely lead to better results.
There are some individuals who may benefit from supplementation. If you cannot eat much following a workout or throughout the day, supplementing helps increase protein synthesis leading to a slew of other benefits. There may also be some benefits for individuals who limit or eliminate animal products from their diets (vegans and vegetarians). However, the vast majority of gym goers should save their money and avoid BCAA supplements. The evidence simply does not support their use.Read full article: The Final Verdict – BCAAs
