If you mean "creatine" ("KREE-a-teēn"), it's a manmade form of a chemical that is normally found in the body.
It's a naturally-occurring amino acid (protein building block) that's found in meat and fish, and also made by the human body in the liver, kidneys, and pancreas.
As per Umm.edu, creatine supplements are popular among body builders and competitive athletes. It is estimated that Americans spend roughly $14 million per year on creatine supplements.
Creatine appears to be generally safe, although when it is taken at high doses there is the potential for serious side effects, such as kidney damage. High doses may also stop the body from making its own creatine. So make sure to take dietary supplements only under the supervision of a knowledgeable health care provider.
Not everyone feels safe taking supplements filled the stuff they don’t know and because of this, they are looking for a natural alternative. Check out some tips on how to increase creatine levels naturally at Muscles.zone.
