Protein powders and supplements are not governed under any restrictions, any one can by them and there not adjusted to fit younger or older people, now I say that, you have to gauge how much you use, if your using them for a nutritional supplement or for a muscle builder after a work out or exercise, then follow the instructions, I know of no country that puts an age limit on these things, Canada, U.S or UK

I was in today and they have a sign saying they do not sell protein powders to under 18s. Sorry :(
