Many individuals in the elderly population may find it difficult or challenging to meet their nutritional needs through dietary means alone. Elderly individuals are more likely to take multiple medications; various medications may cause nutrient depletion, as well as adverse effects that may lead to decreased appetite, thereby affecting the nutritional status of these patients.

Currently, a wide variety of multivitamin/multimineral nutritional supplements are formulated to meet the nutritional needs of individuals aged 50 and older. These multivitamin supplements may include higher levels of vitamin C, folic acid, vitamin D, vitamin E, vitamins B₁, B₂, B₆, B₁₂, and other nutrients, but not iron, because individuals aged 50 and older require less iron and generally meet their iron needs through diet alone.^1-3 Some studies have suggested that high iron stores may contribute to chronic diseases such as cancer and cardiovascular disease; however, research to date is inconclusive.⁴ Some formulations contain gingko biloba for improved memory and concentration, and some formulations are gender-specific to meet the individual nutritional needs of women and men.

Various studies have investigated the nutritional needs of individuals aged 50 and older. Examples of the studies include:

• Researchers found that elderly individuals in Iowa had low intake of most vitamins and minerals and concluded that this patient population would benefit from taking a multivitamin supplement. The study also reported that 80% of the seniors in this study had inadequate intake of 4 or more nutrients.⁵
• Results from a study by McKay et al involving patients aged 65 years and older reported that the use of a multivitamin/mineral supplement decreased illness due to infectious disease by 50% and also enhanced mental function. The study concluded that supplementation with a multivitamin formulated at roughly 100% of the recommended daily allowance could reduce the prevalence of suboptimal vitamin status in older adults and improve their micronutrient status to levels associated with reduced risk for several chronic diseases.⁶
• A study by Chandra reported that the daily use of a multivitamin supplement may improve immune function in the elderly patient population.⁷
• Durga et al investigated whether folic acid supplementation slows age-related hearing loss. The study concluded that folic acid supplementation slowed a decline in hearing of the speech frequencies associated with aging in a population from a country without folic acid fortification of food; however, this requires confirmation, especially in populations from countries with folic acid fortification programs.⁸

Pharmacists should remind elderly patients to discuss the use of a supplement with their primary health care provider before use to ensure its appropriateness. When assisting patients with the selection of a multivitamin supplement, pharmacists should assess the patient's medical history and medication profile to determine if a potential exists for a drug/micronutrient interaction or contraindication. In addition, pharmacists should remind patients to take these supplements as directed and that no substitute exists for consuming a balanced diet. Pharmacists also can refer patients to registered dietitians when warranted.
