Thirty-four individuals with mild cognitive impairment were randomized for 6 months to a nutraceutical formulation (NF: folate, alpha-tocopherol, B12, S-adenosyl methioinine, N-acetyl cysteine, acetyl-L-carnitine) or indistinguishable placebo, followed by a 6-month open-label extension in which all individuals received NF. The NF cohort improved in the Dementia Rating Scale (DRS; effect size >0.7) and maintained baseline performance in CLOX-1. The placebo cohort did not improve in DRS and declined in CLOX-1, but during the open-label extension improved in DRS and ceased declining in CLOX-1. These findings extend prior studies of NF efficacy for individuals without cognitive impairment and with Alzheimer's disease.
