Here s the straight story. Everyone has heard about it. Everyone, it seems, is using it.
Creatine is an amino acid found in foods, such as meat and fish.
The origin of its use as a dietary supplement can be traced to the basics of energy use during exercise. Creatine phosphate is used by the muscles to generate energy for 1 to 10 seconds of intense work, such as weight lifting. Theoretically, this should enable a person to complete more reps in a set at a given weight or lift a heavier weight for a given number of reps. If this is the case, greater improvements in strength and size should follow. The research published on this topic is inconsistent.
