There are 6 common forms of creatine: creatine monohydrate, creatine ethyl ester, creatine hydrochloride (HCl), Kre-Alkaline, and creatine magnesium chelate. But their even more types available usually within a blend: Creatine nitrate, Disodium creatine phosphate tetrahydrate, Creatine phosphate, Creatinol-o-phosphate,Cyclo-Creatine Phosphate.
This isn’t even the end of this list. The point is that there is a large variety of forms of creatine. And while creatine monohydrate is one of the most studied forms, it may not be the best fit for your goals. So by taking a creatine blend you’re getting the benefit of different kinds of creatine. That could be better absorption, greater strength output, more energy, and overall more gains.
