With anything, there are conflicting viewpoints. Be it a supplement, a food or an exercise, one can often find competing opinions and facts to back up each side and the same can be said when it comes to caffeine.
On one side, there’s the argument that it’s a drug, causes anxiety, pushes the pH level of your body into an acidic state and should be avoided all together. The flip side says that it helps to ward off Alzheimer’s, increases memory and helps to increase stamina during exercise. In the past 60 years, researchers have conducted 21,000 studies on caffeine so one would think that we would have a pretty good grasp on disadvantages/benefits of the elixir, but the jury’s still out.
