Improvements to mood, stress and loneliness following 12-week multivitamin supplementation in older adults: a randomised, placebo-controlled, trial

This study provides novel evidence of increased friendliness and decreased stress reactivity and loneliness following MVM supplementation in older adults. These findings support the exploration of broader functions pertinent to aspects of daily living in older adults. Sex differences in response highlight the importance of exploring effects in men and women separately and support a recommendation for the inclusion of diverse samples in future research that are representative of the population.
