It’s National Caffeine Month, and you should know how much is safe. How much is too much?
Up to 400 mg a day is safe for most healthy adults, which is roughly 4 cups of coffee, 10 cans of cola, or 2 energy shot drinks. But remember, there is more than just caffeine in those drinks.
Caffeine’s not a good idea for kids. You should try to limit them to no more than 100 mg per day.
Drinking too much has side effects, like making you jittery, nervous, and irritable and upsetting your stomach.
Too much can also give you muscle tremors, including a fast heartbeat. Cutting back can also help with heart arrhythmia.
It might also be to blame if you always have problems falling asleep, and getting enough sleep is important.
Some medications and supplements may interact with caffeine, including some antibiotics, theophylline, and Echinacea.
Find ways to cut back, and you’ll also probably be cutting back on sugar.
