The number of energy drinks available over the counter is unlimited these days, but how beneficial are these drinks really? "Energy drinks typically feature caffeine and a combination of other ingredients, including taurine, sucrose, guarana, ginseng, niacin, pyridoxine and cyanocobalamin," says Stephanie Ballard from Nova Southeastern University.
But small amounts can be safe and still boost performance. "Caffeine in amounts of up to 6 mg/kg may produce benefits with low risk of adverse effects," she added. The study was published in a recent issue of The Physician and Sportsmedicine. ANI
