Cognitive Function and Memory in Women Over 60: Multivitamin Supplementation Effects
Research on multivitamin supplementation in women over 60 shows mixed but promising results for cognitive health. Some studies found that daily multivitamin use can improve certain aspects of memory, such as immediate recall and spatial working memory, in older adults, including women. For example, one large randomized trial found that daily multivitamin supplementation led to significantly better memory performance compared to placebo, with improvements equivalent to reversing about three years of age-related memory decline . Another study in elderly women with subjective memory complaints found that 16 weeks of multivitamin supplementation improved the speed of response in spatial working memory tasks, though benefits to other cognitive processes were not observed . However, other trials did not find significant improvements in overall cognitive function after multivitamin use, even though some blood biomarkers related to cognition improved Harris2015Mcneill2007.
Mood, Stress, and Wellbeing: Multivitamin Supplementation Outcomes
Several studies have explored the impact of multivitamin supplementation on mood and wellbeing in older women. A 12-week trial found that women taking multivitamins reported higher levels of friendliness compared to placebo, while men experienced reduced stress and loneliness Docherty2022Docherty2024. Another study using in-home mobile phone assessments found that four weeks of multivitamin supplementation improved ratings of stress and showed a trend toward reduced mental fatigue in healthy older women, although these effects were not detected in traditional laboratory mood assessments . These findings suggest that multivitamin supplementation may have subtle but meaningful benefits for mood and stress, especially when measured in real-life settings.
Cardiovascular Health and Hypertension Risk in Older Women
The relationship between multivitamin use and cardiovascular health in women over 60 has also been studied. A large prospective cohort study found that multivitamin use was not associated with a reduced risk of developing hypertension in middle-aged and older women . However, another population-based cohort study in Swedish women found that long-term multivitamin use was associated with a lower risk of myocardial infarction (heart attack) among women with no history of cardiovascular disease, especially with use of five years or more . These results indicate that while multivitamins may not lower blood pressure, they could have a protective effect against heart attacks in certain groups of older women.
Cancer, Mortality, and Safety of Multivitamin Use in Older Women
Large randomized controlled trials have examined whether daily multivitamin supplementation reduces the risk of cancer or all-cause mortality in older adults. The evidence shows that multivitamin use does not significantly reduce the incidence of total cancer, breast cancer, colorectal cancer, or all-cause mortality in older women . Importantly, these studies also report no major safety concerns with daily multivitamin use in this population Macpherson2012Sesso2022.
Conclusion
In summary, multivitamin supplementation in women over 60 may offer modest benefits for memory, mood, and certain aspects of cardiovascular health, particularly with long-term use. However, the evidence does not support a significant effect on overall cognitive function, hypertension, cancer risk, or mortality. Multivitamin use appears to be safe for older women, but its benefits are likely to be subtle and may depend on individual health status and baseline nutritional needs.
