One-A-Day Men's Health Formula

Experts say most men can get all the iron they need from diet -- 8 mg per day -- and reviews recommend One-A-Day Men's Health Formula multivitamins because they contain no iron. The multivitamin also contains 3,500 international units (IU) of vitamin A (14 percent as beta-carotene), 700 IU of vitamin D, 210 mg of calcium and 22.5 IU of vitamin E. One-A-Day Men's Formula contains 157 percent of the recommended daily value (DV) of selenium, which Bayer used to claim may improve prostate health. After litigation claiming deceptive advertising, Bayer was forced to pay a fine late last year and remove that claim from all of its advertising. Some user reviews note difficulty swallowing One-A-Day Men's Health Formula because it is a large pill.

The amount of iron is a major difference between men's and women's vitamins; premenopausal women lose iron during menstruation cycles, so for women, reviewers prefer One-A-Day Women's (*Est. $11.50 for 100 tablets) which contains 18 mg of iron. If you're over 50, reviews recommend Centrum Silver (*Est. $11 for 100 tablets).

Because the multi hasn't been included in recent multivitamin tests, the best source of information about One-A-Day Men's comes from user reviews. The Center for Science in the Public Interest doesn't test the multi, but they provide information on the supposed benefits of selenium. The free section of ConsumerReports.org's coverage of multivitamins contains all the information most people need to know -- that you can count on acceptable quality with brand-name or store-label multivitamins. User reviews are unscientific, but helpful for input on how easy it is to swallow the pill and how many people experience nausea.
