Everything guarana can do, caffeine can do better.

Guarana is a natural source of caffeine, and many time getting caffeine from a natural source is preferable. We’ve reviewed a few energy drinks with guarana.

When doing research for my book, I remember being most intrigued by this energy drink ingredient because it was such a mystery ingredient.

For last week’s book excerpt, we talked about what glucuronolactone is. For this week’s Book Excerpt from “Are You a Monster or a Rock Star”, we consider one theory behind what glucuronolactone does and why it might be useful in energy drinks. Read more →
