Considering Creatine?

Popular among athletes, creatine is growing in popularity with those who are looking to build muscle mass. It is a naturally occurring amino acid (protein building block) that's found in meat and fish. The liver, kidneys, and pancreas in our bodies also produce it. It is converted into creatine phosphate and stored in our muscles, where it is then used as energy.

Creatine's rise in popularity is due to studies that have shown that it may increase lean muscle mass and enhance athletic performance. This is particularly useful in short duration sports that are high intensity (weight lifting). However, human studies have been variable on the improvement of athletic performance. Not every person seems to respond the same way to the supplements. People who tend to have naturally high stores of creatine in their muscles don't get an energy boosting effect from the extra creatine. Some studies have show that creatine may combat muscle weakness associated with illnesses such as muscular dystrophy. There is no direct link established between creatine and rheumatoid arthritis. It has been shown to increase memory one study where vegetarians were given 5 grams of creatine a day for 6 weeks.

Given the variable nature of this amino acid, consulting a doctor would be advisable before taking it. All the studies have resulted in some mixed conclusions, so the only way to really know what your results would be is to simply try it.
