Taurine, Energy Drinks, and Neuroendocrine Effects

Taurine is an amino acid found abundantly in brain, retina, heart, and reproductive organ cells, as well as in meat and seafood. But it is also a major ingredient in popular "energy drinks," which thus constitute a major source of taurine supplementation. Unfortunately, little is known about taurine's neuroendocrine effects. The authors review the sparse data and provide a basic background on the structure, synthesis, distribution, metabolism, mechanisms, effects, safety, and currently proposed therapeutic targets of taurine.
