Can you tag this onto the sticky at the top Alex?
Just a note for vegtarians/vegans that they have to watch out because a lot of the cheaper creatine supplements are animal sourced!
But on the bright side vegetarians/vegans are more responsive to the effects of creatine supplementation on exercise performance than their carnivorous counterparts. That was the clear conclusion of a Canadian study on creatine-supplemented recreational athletes following an eight-week resistance training programme a few years ago.
at baseline, there were significant differences between the vegetarians and the non-vegetarians, with the former consuming lower total calories and lower calories as protein than the latter, as well as demonstrating lower total muscle creatine concentrations, but with no differences in 1-RM bench press and leg press;
creatine subjects showed greater increases in phosphocreatine, total creatine, bench-press strength, isokinetic work, type 2 muscle fibre area and whole-body lean tissue than those on placebo;
vegetarians/vegans who took creatine showed greater increases in total creatine, phosphocreatine, lean tissue and total work performance than their non-vegetarian counterparts.
