With caffeine overdoses being an increasingly occurring issue as more people are consuming greater amounts, it is essential to know just how much your caffeine intake is. With thousands of different workout and protein supplements being on the market, each one is different and contains varying amounts of additives. Caffeine is often found in supplements, meaning you don’t need to add any more to your protein shake. The Office of Dietary Supplements at the National Institutes of Health recommends taking 2 to 6 milligrams (mg) per kilogram of body weight 15 to 60 minutes before you exercise, and that the average adult shouldn’t consume more than 500mg a day.
