Creatine phosphate is not easily absorbed by the body, and the effect of muscle gain is not obvious; The experimental feedback of creatine citrate is less, so it is impossible to know its effect. At present, the most common research is about creatine monohydrate, and the absorption mode of esterified creatine is different from the first three creatines, emphasizing faster and more sufficient absorption. In addition, there are anhydrous creatine, creatine malate and other products, but their effects have yet to be verified.
In any case, we can be sure that the key to the effect of creatine products lies in purity, which has little to do with its existing form. High purity creatine should be at least 99.9%.
