Hmmm....Multi-vitamins. Water soluble vitamins that you cannot use will be pissed out, and most fat soluble levels are not even close to the toxic levels. The Minerals however that most companies use are metalic, and come from oyster shell or other sea products. the problem is that our bodies were never intended to digest them, so we absorb about 3-5% of it and that's it. Then the chelation process came along....they wrap an amino around the metalic mineral and BOOM we're able to absorb 30-40% of the mineral. I purchase a decent muti and take it with each meal, along with an antioxidant and my efa's that way I know I'm getting enough. Hope this helps.
