You may have heard that you are a "slow" or "fast" oxidizer of caffeine which determines how you respond to coffee and caffeine. Until now I never understood what it is we're after when we consume caffeine: is it energy or is it paraxanthine?  Shawn Wells, author of the Energy Formula and cofounder of Enfinity, breaks down the metabolite that is behind all of the health benefits of caffeine. Paraxanthine is still a stimulant  but its effects are smoother than caffeine, especially for us slow metabolizers, which according to one study is nearly 60% of us. He shares the current research on this fascinating alkaloid up to this point and I share my experience drinking the Update energy drink as a coffee replacement.
