A meat eating american ingests more than enough creatine and your body can make it. Its not particularly dangerous but like many things having to much effects depending on substance either the liver or kidneys depending on the substance (apparently this one is kidneys). This is why its bad to get to much of most anything as you body has to deal with eliminating it. Some water soluble things are almost impossible to get to much of as it does not need to be filtered out but even water you can have too much of but that is more due to electrolyte balance. Anyway if your supplementing then you better excersise enough to actually use it and that should be real strength training. Don’t be taking because you intend to excersize. Be dependable in your excersise routine and then you can start supplements and junk.
