New and exciting research is still being conducted on BCAAs and their applications to muscle growth, fat loss, and performance. There are not many supplements in existence that have the ability to affect growth and performance through as many different pathways as BCAAs. While BCAAs have proven benefits as a building block of muscle tissue, their benefits as signaling molecules are truly just being understood. In time BCAAs may just prove to be the most valuable supplement at our disposal. So the next time someone accuses you of being just another meathead talking about protein all the time, you can show them that it is more than just eating plates of chicken and beef…it’s science!
