For over 70 years, Vivarin has been a trusted alertness aid, long before syrupy drinks hit the scene. Most energy beverages have just as much caffeine as Vivarin — but a lot of other ingredients as well. As a result, nutritionists are concerned about the safety and effectiveness of the blends and how the ingredients may interact with one another. So, think about it this way… if you don’t know all of what’s in it — and can’t pronounce much of what is — should you really be drinking it? Oh, and the price tag is pretty steep, too.
