Studies of RCTs carried out on people with any type of dementia who were taking nutritional supplements and had neuropsychiatric symptoms were included in this systematic review and meta\u2010analysis. Neuropsychiatric symptoms were assessed with the validated Neuropsychiatric Inventory (NPI). Effect sizes were calculated with standardized mean differences (SMD) and 95% confidence intervals (95%CI), applying a random effect model.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The search yielded 1034 studies with four studies being included in the meta\u2010analysis with a total of 377 people with dementia (mean age 69.3 [SD: 7.7] years). The diagnoses comprised mild to late Alzheimer's disease and frontotemporal dementia. Two studies included a multicomponent supplementation, one an omega\u20103, and one a special supplement tailored for cognitive impairment. The median follow\u2010up was 18\u2009weeks, with a range from 12 to 24\u2009weeks. Pooled data showed that nutritional supplementation did not improve NPI (SMD = \u22120.33; [95%CI: \u22120.74 to 0.08]; <jats:italic>P<\/jats:italic> = 0.11; I<jats:sup>2<\/jats:sup> =\u200945%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The findings of this meta\u2010analysis demonstrated no significant impact on NPI through nutritional supplementation.
