otc energy pills and supplements contain a large amount of caffeine sometimes 2-3 times the amount of a cup of coffee depending on the brand. by increasing your daily caffeine dosage you may be increasing your risk of caffeine addiction. and too much of any stimulant has consequences for the body such as elevated blood pressure and an increased heart rate. this could be dangerous. i would use these products with caution or not at all. the risk can be greater than the value of the short energy boosts they provide.
is it safe to take otc energy pills/supplements if you drink a lot of coffee?
