Grande Coffee Has Way Too Much Caffeine
Caffeine is obviously effective in improving mental alertness. However, studies clearly show that too much caffeine (in excess of 100 milligrams) can be detrimental to your health by causing muscle tremors, fast heartbeat, migraine headaches and other health issues. Astonishingly, a 16-ounce of Starbucks’ coffee contains nearly 310 milligrams of caffeine! This means that it has over four times the amount of caffeine available in world’s most famous energy drink, Red Bull, which is just 80 milligrams.
