Creatine is a natural amino acid that is produced in your liver, pancreas and kidneys. Creatine can also be found in proteins like fish or meat, and according to the University of Maryland Medical Center, it is a fundamental source of energy for the human body. If your body is lacking in creatine, there are supplements that can be taken to increase the levels of creatine in your body. If you are considering using a creatine supplement, you should speak with your doctor to assure that it will not interfere with any other treatment you are currently taking.
Low Levels
Low creatine levels have been linked to muscle, respiratory and circulatory diseases, as well as rheumatoid arthritis. PeaceHealth states that your creatine levels can be low due to a diet that is restrictive of meats or if your activity levels are elevated and extreme. If you have low levels of creatine, there is a variety of supplements in drinks, powders, tablets and bars that can boost your levels. Speaking with a pharmacist can help make the decision of which supplement is best for you.
High Levels
High creatine levels may be due to overindulging in meats or supplements. There does not appear to be a direct link with high levels of creatine and any diseases, but according to Medline Plus, creatine can cause your muscles to draw in water, which may lead to dehydration. Care should be taken when supplementing with creatine and the University of Maryland Medical Center suggests 2 to 5 grams a day for maintenance exercise performance.
Benefits
Creatine supplemental use has been found to be beneficial on several fronts. The main benefit is the increase in strength and muscle mass associated with its use. A study published in the International Journal of Sport Nutrition and Exercise Metabolism shows that resistant exercises and upper body exercises seem to be the best at increasing lean muscle mass while taking creatine supplements. The University of Maryland Medical Center claims that creatine may help with heart disease, COPD, muscular dystrophy and even in Parkinson's disease, but warned that more studies are needed in these areas.
Considerations
The use of creatine supplements can be beneficial for all, but Medline Plus claims that people who have low levels in the beginning will benefit from its use more than those with higher levels. Medline Plus claims this is due to the maximum allowance of creatine in the muscles. Once that point is reached, adding more creatine is unnecessary.
Warning
Diarrhea and cramping seem to be the most common side effects of taking a creatine supplement. Although these are not considered life-threatening, diarrhea can lead to dehydration, which is already a risk with high creatine levels. You should also discuss creatine use with your primary care provider to make sure there are no interactions with the medicines or other alternative treatments you may be taking.
