first you'll want 2 find out if your vitamins r fake or real. the way 2 do that is 2 put them in water and if they dissolve within 20min they r real if they dont your just goin 2 crap them out and waste your money. synthetic vitamins that do get into your system have been shown to cause health problems so make sure your getting the real thing. i take DoubleX from Nutrilite it has 3 pills multi vit/mineral & phytonutrient. all there supplements r natural so some might b a little pricey but u get what u pay for. better get something that works rather than something your goin 2 crap out. go 2 www.zelliott.qhealthbeauty.com i've been using there products & wont use anything else
