There are 2 Health Food/ Exercise Food places on Lyndhurst Terrace just near Dubline Jacks. One is called American Nutirion I think and the other is on the other side of the escalator but I don't know its name. Don't know a great deal about this stuff but went into both for the first time on the weekend and they look to have most things ie: protein powders, EAS drinks in the fridge, Zone and Low Carb bars and lots of supplements.
