Branched-chain amino acids are leucine, isoleucine, and valine. These three amino acids are essential. They are coupled together, hence the name "branched-chain amino acids." They're chained together. There's probably not more studies and more data done on any other amino acids rather than these three essential amino acids with regard to their ability to help people put on lean muscle tissue. Supplementing your daily weightlifting program with branched-chained amino acids is going to help you to build up your body's ability to synthesize protein, keep your body anabolic. It's also going to help within the muscle cells to keep your muscles from literally degrading post-workout.
There's different ways you that you should administer BCAAs. If you're having a whole protein source, even if you're ingesting BCAAs, which you'll get in a complete protein powder or drink, it's also important to implement BCAAs outside of that by taking them by themselves. They come in capsule form. They come in powder form. I would highly recommend taking BCAAs before you work out, after your work out, but also probably as well during your workout. What that's going to do is hydrate the muscle and prepare the muscle anabolically so that your body is literally going to be not only making muscle after the workout, but it's actually going to prevent the muscle breakdown while you're working out. It's a phenomenal supplement that's irreplaceable.
