Creatine Cramps & Heat Stress
I've been challenging all of these reports of alleged side effects for over a dozen years when the research began to make it clear that creatine actually doesn't cause bloating or kidney stress or...anything else except better muscular performance and muscle growth.
Another "side effect" that many athletes and even coaches and nutritionists of professional sports teams still believe in is cramping. Many still believe that creatine increases the risk of muscle cramps, so they warn their players not to use creatine.
This is another area in which I've said for years there was never any good evidence for - actually the only study that showed any effect in this regard, showed "less" cramping among creatine users, not more!
Well, now a recent study conducted at the University of Glasgow has confirmed this result. When creatine was given to endurance athletes along with glycerol (also known to assist with water retention and better hydration), they experienced lower core body temperatures and could complete the same exercise challenge with a lower heart rate (better exercise efficiency) in hot, humid conditions.
So just more evidence that not only is creatine safe and free of side effects, it actually reduces risk factors for cramps and heat stress during exercise.
