Table 3 Mean (SD) peak plasma concentration (Crmax, mM), time to peak concentration (Tmax, h), area under the plasma concentration curve (AUC, mM.h), velocity constant of absorption (ka, h-1) and velocity constant of elimination (ke, h-1) following ingestion of isomolar amounts of creatine (4.4 g) in the form of creatine monohydrate (CrM), tri-creatine citrate (CrC), or creatine pyruvate (CrPyr). Means differing significantly are denoted by the letters a to c.
