The Effects of Four‐Week Multivitamin Supplementation on Mood in Healthy Older Women: A Randomized Controlled Trial

Abstract

Objective. Nutritional deficiencies have been associated with cognitive decline and mood disturbances. Vitamin intake can influence mood and randomized controlled trials have demonstrated that multivitamin supplements are capable of reducing mild symptoms of mood dysfunction. However, few studies have focussed on healthy older women. Methods. This study investigated the effects of four weeks' multivitamin supplementation on mood in 76 healthy women aged 50–75 years. Mood was assessed before and after intervention in the laboratory using measures of current mood and retrospective experiences of mood over the past week or longer. Mobile phones were used to assess changes in real-time mood ratings, twice weekly in the home. Results. There were no multivitamin-related benefits identified for measures of current mood or reflections of recent mood when measured in the laboratory. In-home assessments, where mood was rated several hours after dose, revealed multivitamin supplementation improved ratings of stress, with a trend to reduce mental fatigue. Conclusions. Over four weeks, subtle changes to stress produced by multivitamin supplementation in healthy older women may not be detected when only pre- and posttreatment mood is captured. In-home mobile phone-based assessments may be more sensitive to the effects of nutritional interventions compared to traditional in-laboratory assessments.

A Systematic Review and Meta-Analysis of B Vitamin Supplementation on Depressive Symptoms, Anxiety, and Stress: Effects on Healthy and ‘At-Risk’ Individuals

“…Seven studies included three to four other constituents, with the remaining containing a higher number of micronutrients or botanical constituents. The largest amount of other constituents came from Macpherson, et al [49], with a total of 37 additional constituents.…”

Nutrition Bio Shield (NBS) supplement effects on depression, anxiety, stress and food craving in women with depression and obesity: a double-blind randomized controlled trial

“…But the NBS supplement is processed from whole grain wheat enriched with broad spectrum micronutrients. A double-blind randomized controlled trial Macpherson et al also administered multivitamins to healthy females for four weeks and reported no significant improvement in symptoms of depression, anxiety or stress (Macpherson et al, 2016). They included women with a different age group (50-75 year old).…”

Bibliometric mapping of the landscape and structure of nutrition and depression research: visualization analysis

“…Several studies have investigated the relationship between a healthy diet and individual nutrients and their impact on depression, such as fatty acids, vitamins, and minerals [ 12 – 14 ]. Moreover, intervention studies using supplements that include several nutrients, such as multivitamins, have examined the overall effect on patient mood [ 15 – 17 ]. In particular, increased fruit and vegetable intake has been widely associated with a better psychological and health status and a decrease in the likelihood of depressive symptoms [ 9 – 11 , 18 ], while other studies revealed that the association is insignificant [ 19 – 21 ].…”
