Vitamins for men and women differ in nutrient amounts. Women lose iron during the menstrual cycle, and those who expect to have children need folic acid to help prevent neural tube defects. Reviewers suggest Centrum A to Zinc for premenopausal women because it contains 18 mg of iron and 400 mcg of folic acid. In a 2010 Pharmacy Times survey, 60 percent of surveyed pharmacists recommend Centrum multivitamins. If you're pregnant or lactating, reviews suggest Rite Aid Prenatal Tablets with Folic Acid (*Est. $18 for 225 tablets); it has increased folic acid and a higher percentage of vitamin A to help prevent birth defects. For older women, experts like Centrum Silver Adults 50+ (*Est. $9 for 100 tablets), which has more B12 for seniors.
