That part simply makes me wonder what "proven" means to the Mayo Clinic...ie. does it have to be a prescription item under a doctor's care? |
I presume they mean that it's efficacy is not proven because there are responders and non-responders and at present there is little evidence to suggest that creatine supplementation gives athletes a significant competitive advantage over athletes that obtain their creatine from dietary sources i.e. meat.
