multivitamins fill the gap between our highly deficient diets and what our body needs. foods being so heavily processed today, we get very little in the way of vitamin and mineral nutrient. even those who are good little troopers and eat their veggies will have to eat quite a bit of those vegetables and quite a variety to get what one needs in a day.
choosing a good multivitamin is the next toughest choice. many of them have such poor absorption rates that you just piss it all out, literally. do some research on what companies have good absorption rates and make your decision from there. just a hint, centrum....35% abs. rate.
