Does caffeine inhibits the effects of creatine?
No one is sure right now, whether caffeine inhibits effects of creatine or not. But one study was conducted by some scientists that showed that caffeine do inhibits the effects of creatine. In that study, one person was given a creatine supplement and one person was given caffeine + creatine. After that scientists measured whether the creatine was taken up into the cells or not, and found that both the persons had gained creatine in their cells. But, the person who had taken creatine + caffeine did not showed any beneficial effects as compared to the person taking pure creatine, who showed many beneficial effects (about 10% – 25% more beneficial effects).
