some more info on creatine for anyone interested
In humans, approximately half of stored creatine originates from food (mainly from fresh meat and fish). Since vegetables do not contain creatine, vegetarians clearly show lower levels of muscle creatine which, upon creatine supplementation, rise to a level higher than in meat-eaters

so basically by adding extra creatine, which is basically an extract from meat, its just upping the levels in your system
