See how yellow your piss is.....
When i take my multi vitamins, wich i bought in a health store, which have amazingly high levels of everything men needs, from zinc to vitamin C, to serbian ginseng, and minerals.
BUT when i take them, i PEE fucking NEON yellow. So i stoped taking a whole serving, (2 pills) and take one in the monring and 1 at night. BUT my PEE is still a bright neon yellow.
But when i take centrum my pee would be clear, i hear this is because your body used up all the ingrediants of the pill, but when its yellow, i believe your body is flooded with vinamins and the excess is peed away, meaning
You body cant utilize any more vitamins because it has all it needs
But i ahve heard, that centrum is store quality, while vitamin store, gnc , etc vitamins are pharmacutical grade. Just my 2 cents
So i recomend not going cheap, but not going crazy either, i would say 15-20 bucks for decent vitamins, ( a months worth)
