Redback Creatine is so efficient at shuttling water into the intramuscular compartment, that an emergent side effect associated with it is that of muscle cramping. This most often occurs when too little fluid is consumed whilst supplementing with creatine. Muscle Cramping, strains and tears are all anecdotal evidence that are not supported by scientific fact. Creatine draws water away from the internal working organs and therefore if you take a lot with no water then a mild stomach cramp will occur.
