What they are: One-pill wonders that offer 100 percent of the recommended daily allowance (RDA), as suggested by the Institute of Medicine
of the National Academy of Sciences, for many important vitamins.
Benefits: They give you much of what you need in a day, including vitamins A, C, D, and E, B vitamins, and folic acid. Bonus: You have
only one tablet to remember to take and swallow. Try One A Day Essential Multivitamin ($10 for 130 tablets, drugstore.com).
Keep in mind: Some single pills also include minerals, such as iron, calcium, and magnesium. But their levels can fall short of what’s
recommended. The RDA for calcium, for example, is 1,000 to 1,200 milligrams. But because calcium is bulky, including that
much would make for one giant pill. Therefore an additional mineral supplement may be wise in some cases. (Note: Check with
your doctor before introducing any vitamins or supplements into your diet.)
