To get enough of most of the vitamins you need from One a Day, you would need 5 or 6 a day then you may be overdoing it on some micro-nutrient. Plus, the mag oxide dose would have you running. It borders on homeopathic. fyi, Homeopathic is a nutrition and drug regimen where the body is supposed to react in a positive way to an almost imperceptible level of the compound. It is like tossing a vitamin in a full bathtub, getting it dissolved. Then consuming an eye dropper of the water. If you get to GNC and buy some MegaMen or equivalent, give the One a Day to a friend or enemy.
