If amino acids were the Brady Bunch, taurine would be screaming, Leucine, leucine, leucine! After all, leucine very well does appear as the sexiest, most worthwhile amino acid to include in supplement formulas, and for good reason. As we detailed in our discussion of BCAAs, leucine has a deep pool of data behind it, and most of it is very encouraging.

But taurine is no joke, either. While the focus of the bodybuilding community has been on its cousins, the BCAAs, the scientific community has known for some time that taurine is arguably the more critical compound to the human body. Taurine plays a role in some very key physiological processes, many of them related to exercise.
