What kind of supplements are you referring to? Protein bars, protein powders, creatine, pre/post workout stuff...I get all mine either from Sams Club/Costco if they have my brand...or www.***************** which pretty much has everything you can think of.
That's because grocery capitalists separate those two things in the hope that their customers remain ignorant to the fact that, given a diet rich in fresh fruits and vegetables, they don't need so-called supplements. *
"You gotta keep 'em separated."
* Yes, that was an embellishment. But the message is quite real.
