Myth: If you have nutrition deficiencies, a multivitamin will provide all the missing nutrients.
Fact: Although multivitamins can help supplement certain deficiencies, it is not possible to get all the benefits of eating a healthy diet simply by swallowing a daily pill. Experts agree that while you may be able to complement healthy eating habits, you should not rely on multivitamins as a replacement for eating nutritionally rich foods.
Myth: It canâ€™t hurt if you take more of a supplement than you actually need.
Fact: Too much of some pill-based vitamins and minerals can come with unexpected or dangerous side effects. And that is true both for the quantity of pills as well as for their composition. Indeed, one study has shown that taking certain antioxidant pills that contain too much vitamin E can actually promote cancer.
