Multivitamin supplements show no benefit in preventing chronic disease.
Almost 6000 male physicians 65 and older received either a daily multivitamin supplement or placebo. Testing after 8.5 years of follow-up showed no significant difference in verbal memory or global cognition. In yet another study, 1700 adults aged 50 or older were given a multivitamin or placebo beginning 6+ weeks following a heart attack. After 4.5 years the outcomes were no different for either group. Both studies were randomized and double-blind.
PositiveTip: Supplementing the diet of well-nourished adults has no clear benefits. Enough is enough!
Myocardial infarction, stroke, and death not affected by multivitamin supplements.
A randomized controlled study involving almost 15,000 male physicians over a median period of 11 years found no difference between those taking commercial daily multivitamins and the placebo group.
PositiveTip: Choosing foods rich in vitamins and minerals, such as vegetables, fruit, and whole grains, is still the best way of meeting nutrient needs.
