Question: There are so many different formulas of multivitamin (women's, men's, energy, muscle, etc.). Is there any particular formula that's better than the rest?
Answer: The variety of formulas on the market, for the most part, is a marketing strategy by the different companies to get attention to their particular product. There are exceptions to this -- for example, prenatal vitamins. Pregnant women have specific needs of multivitamins that are different than others. Also, menstruating women may have a need for additional iron, whereas men and women who are older than 50 or so after menopause don't have a need for additional iron.
Often the companies place additional herbs into a multivitamin to differentiate themselves and to make particular claims, but the doses of these herbs are usually too low to have significance in terms of their health benefits. And so I recommend that people take multivitamins without these additional herbs and add herbs or other supplements as needed for particular conditions that they may be treating.
