Meeting the Nutritional Needs of Men

Pharmacists can counsel male patients on the appropriate way to incorporate multivitamin/multimineral supplements formulated for men into a nutritional plan.

The use of multivitamin/multimineral supplements is a growing trend in the United States, as an estimated one third of adults use these supplements on a regular basis^.1 The American Dietetic Association position to promote optimal health and decrease or prevent the risk of chronic medical conditions is to consume a diet that contains a wide variety of nutrient-rich foods.¹ Their position also states that obtaining additional nutrients from supplements may be beneficial to some individuals in meeting their nutritional needs, as specified by science-based nutrition standards such as the Dietary Reference Intakes from the Institute of Medicine.¹

While many individuals use nutritional supplements, a 2009 report from the US Government Accountability Office stated that “according to experts, consumers are not always well-informed about the safety and efficacy of dietary supplements and may sometimes have difficulty interpreting labels on these products.”¹ Therefore, pharmacists can be a vital resource for those individuals electing to use a nutritional supplement by assisting in their selection and proper use.

Currently, many manufacturers market supplements specifically for men in various age groups, including formulations for teenagers, men aged 50 years and younger, and men older than 50 years. Supplements formulated for adult men contain key nutrients, such as vitamins B6, B12, C, and E and folic acid to support cardiovascular health; vitamins A, C, and E and the mineral zinc for ocular health; and vitamin C, calcium, magnesium, and higher levels of vitamin D to promote healthy blood pressure levels.^2,3 Typically, supplements formulated for men do not contain iron.^2,3

The supplements marketed for teenagers include key nutrients for optimal health during this phase of life, such as magnesium for healthy muscle function, as well as calcium, vitamin D, and magnesium for bone strength.⁴

One of the newest supplements for men is One A Day Men’s Pro Edge (Bayer Healthcare), which is formulated with key nutrients to meet the nutritional needs of those men who routinely exercise or engage in sports.

In general, supplements formulated for those older than 50 years may include larger amounts of vitamin C, folic acid, vitamin D, vitamin E, and vitamins B1, B2, B6, and B12, but no iron, since individuals in this patient population generally require less iron and meet their iron needs through their diet alone.^3,5-7 Some studies have suggested that high iron stores may in fact contribute to conditions such as cancer and cardiovascular disease; however, research to date is inconclusive.^2,3,5-7 Supplements formulated for men older than 50 years may also contain ginkgo for memory and concentration function.²

Prior to recommending any multivitamin/ multimineral supplements, pharmacists should assess the patient’s medical history and medication profile to determine if there are any existing contraindications or potential for drug/micronutrient interactions. They should also remind patients to take these supplements as directed.

Finally, pharmacists should stress the importance of incorporating a balanced nutrition plan into their patients’ daily routine and provide a referral to a registered dietitian when necessary.
