I'm full aware of multiple sources of plant based vitamin supplements that can be grown in house and aren't as exotic as one would think.


HOWEVER -when- SHTF I would like enough shelf vitamins or concentrates to tide one over until such said plant vitamins are grown. I'm ALSO aware that it'd not be all that damn difficult to hawk vitamins that just don't stay in the body very long, and are expelled by sweat, pee, even exhalation.

ANy one got solid data on long body duration, long shelf life multivitamins in quantity? Or should I just buy a couple gallon jar sized bottles of generic Centrum Silver (being 54),and stick them with the loadout?
