Creatine Ethyl Ester: Creatine Ethyl Ester offers superior absorption compared to creatine monohydrate. There are other creatine formulas, some of which are patented. These perform better than traditional creatine monohydrate. That is why you only need a much smaller serving of creatine ethyl ester twice a day (compared to up 10 grams of creatine monohydrate), and there is no “loading phase.” Studies have shown that creatine also raises your metabolism by up to 100 calories a day, which is another reason why you need to take it.
