How much caffeine is too much?

Health & Fitness Diet & Nutrition

I drink 4-8 espressos on a daily basis and take a caffeine pill (200mg) every morning to keep myself awake. I tend to feel tired all the time, so caffeine helps me stay functional. How much caffeine is too much? I have not experienced sleeplessness, jitters or nausea at all, but I'm still concerned. Hope you can advise.

DOCTOR’S ANSWER (1)

Although caffeine use may be safe for adults and may even provide health benefits in many people, excessive caffeine consumption can also pose health problems. No more than a maximum of 400 mg of caffeine a day is recommended as a dietary intake guideline. That is the same amount present in four cups of brewed coffee, 10 cans of cola or two energy drinks.

Women who are pregnant, breastfeeding, or trying to conceive should seek medical advice about their caffeine intake. If one experiences symptoms such as migraine, headache, insomnia, anxiety, frequent urination, fast heartbeat, and abdominal discomfort, one should consider reducing their caffeine intake.

Light and moderate caffeine intake have been shown to demonstrate health benefits such as heightened brain function, better memory, increased energy levels, fat-burning, and improving stamina. Caffeine is also associated with decreased risk of developing Type 2 diabetes, Alzheimer's disease, dementia and Parkinson's disease. Coffee and tea, which are the most popular caffeinated beverages are also rich in powerful antioxidants, and many people obtain more antioxidants from these beverages than from fruits and veggies combined.
