how does caffeine boost energy
Caffeine is documented to boost athletic power and endurance, so you can exercise harder and longer. Caffeine has a direct metabolic effect on muscle, to improve endurance. In biological terms, caffeine helps muscle burn fat as the energy source, instead of glycogen (a carbohydrate).his means that if your parents seem to get strong effects of caffeine on a small amount-a half cup, say-you are likely to have the same kind of response. Look to your family tree, to get a clue of how much caffeine might work for you in a health promoting way. This does vary! 7.
