Creatine supplements are used to increase size, strength and athletic performance. Several forms of creatine supplement exist - from creatine monohydrate, kre-alkalyn, creatine gluconate, magnesium creatine chelate and creatine ethyl ester (CEE). CEE is a form of creatine designed to have higher absorption rates and a longer serum half-life than regular creatine monohydrate. Kre-Alkalyn is designed to offer better absorption, with zero bloating. Creatine administration has been shown to significantly improve performance in cognitive and memory tests in vegetarian individuals involved in double-blind, placebo-controlled studies. Vegetarian use of creatine sports supplements seems to be especially beneficial as they appear to have lower average body stores, since meat is the main source of dietary creatine. We highly recommend creatine supplementation for all healthy, weight-training adults.
