MEMPHIS, Tenn. -- Caffeine is being blamed for the death of a Ohio teenager who overdosed on something perfectly legal, something not even regulated by the FDA.

It's called caffeine powder and it is way more powerful than what you find even in energy drinks.

Dr. Amit Maholtra, a cardiologist at Baptist Memorial Hospital-Desoto Hospital joined us to talk about the possible dangers.

Pure caffeine powder can easily be bought on the internet in bulk, and because it's labeled as a supplement, it's not currently regulated by the FDA.

The recommended dose is 250 mg or 1/16 of a teaspoon, the caffeine is the equivalent of three Red Bulls.

If someone took just one full teaspoon, that would be 50 Red Bulls at once.

That much caffeine could cause strokes, decrease blood flow to the heart and brain which could cause seizures or even turn fatal.

The American Academy of Pediatrics recommends adolescents get no more than 100 mg of caffeine a day.

That much could easily be found in one cup of coffee or 8 ounces of energy drink.
