==========
Creatine is not a drug, but rather a substance that naturally occurs in muscle tissue. Creatine is a combination of 3 amino acids; arginine, glycine and methionine. It can also be found in high quantities in some foods (Tuna, Herring and Beef), though not high enough to be beneficial to be considered a method of supplementation. Creatine monydrate, the supplement form of Creatine, is a white, flavourless and odourless powder.
Creatine helps provide the energy our muscles need to move, particularly quick and explosive movements. Muscle contractions within the body are initially fuelled by ATP (adenosine tri-phosphate ). Our bodies have only a limited supply of ATP and can provide energy for only a short time before failure. Supplementation with Creatine increases the rate at which the body can supply ATP and hence allows an extra burst of energy. In basic terms,
creatine supplementation will allow you to lift more weight, or push out an extra couple of reps.
Creatine has been linked via anecdotal evidence to muscle cramps and headaches.
Scientific studies have yet to substaniate these claims. Approximately 5% of people are non-responders, usually due to abnormally high levels of creatine in their skeletal structure.
