Are there any side effects to taking energy drinks and/or bars?
This really depends on the ingredients that are within your specific energy product. Side effects are dependant on the constituent ingredients, just as is the case with many of the pills that people can take. In a general sense, one side effect that you should definitely watch out for is the dreaded “crash” that accompanies the time period just after the effects of the energy product have worn off. If this is poorly timed, it can really make things difficult for you, but the good news is that most energy products come with only a mild crash effect and even in the case of the ones that are real jolts that come with larger crashes, the crash is not a serious side effect by even the most conservative viewpoint of side effects.
