Addressing nutritional gaps with multivitamin and mineral supplements

Area of Science:

• Nutrition Science
• Public Health
• Gerontology

Background:

• Dietary deficiencies in essential vitamins and minerals can occur even in populations with access to nutrient-rich foods.
• The typical American diet often lacks recommended amounts of fruits, vegetables, and whole grains, increasing the risk of micronutrient deficiencies.
• Chronic deficiencies can lead to significant health problems, underscoring the need for nutritional support.

Purpose of the Study:

• To review the role of multivitamin and mineral (MVM) supplements in maintaining health and preventing chronic conditions.
• To examine the evidence supporting MVM use for specific health outcomes, including nutritional gaps, chronic disease prevention, and cognitive function.
• To assess the safety profile of MVM supplements compared to single-nutrient supplements.

Main Methods:

• Literature review and synthesis of existing research on MVM supplementation.
• Analysis of studies investigating MVM efficacy in preventing conditions such as anemia, neural tube defects, osteoporosis, cancer, cataracts, and cognitive decline.
• Evaluation of safety data regarding MVMs and their association with mortality and major diseases.

Main Results:

• MVMs are effective in filling critical nutritional gaps, aiding in the prevention of conditions like anemia, neural tube defects, and osteoporosis.
• Emerging evidence suggests potential benefits of MVM supplementation for cancer prevention (especially in men), cataract delay, and certain aspects of cognitive performance.
• MVM supplements are generally well-tolerated and do not appear to increase risks of mortality, cerebrovascular disease, or heart failure.

Conclusions:

• The potential benefits of MVM supplements likely outweigh the risks for the general population.
• MVM supplementation may be particularly advantageous for older adults to address age-related nutritional needs and health concerns.
• While research on chronic disease prevention is ongoing, MVMs play a role in maintaining overall health by addressing micronutrient deficiencies.
