Since the iron in most multivitamins bothers my stomach, I’ve never gotten in the habit of taking them regularly. I do take kid vitamins that are iron-free, but that may not be necessary:
No large study has shown that multivitamins significantly benefit healthy men and women..but vitamins can be valuable in certain situations:
- Folic acid supplements in women who are pregnant or plan to become pregnant can help to prevent serious neural-tube defects that affect the baby’s brain and spine.
- Supplements that contain more vitamin D and calcium than is present in regular multivitamin pills can help older men, and especially women, avoid osteoporosis and bone fractures.
- Supplements of vitamins C and E, beta-carotene, zinc, and copper may slow the progression of vision loss in people with early macular degeneration.
And multivitamins are beneficial for some entire groups of people:
- those on a very-low-calorie weight-loss diet
- strict vegetarians
- heavy alcohol drinkers
However, everyone can use some exercise.
