Sodium benzoate treatment decreased amyloid beta peptides and improved cognitive function among patients with Alzheimer's disease: secondary analysis of a randomized clinical trial.

ABSTRACT: With the recent approval of anti-amyloid beta (Aβ) monoclonal antibody infusion therapies for Alzheimer's disease (AD), more feasible and safter Aβ-reducing approaches are anticipated. Previous studies showed that 750-mg/day or 1000-mg/day (but not 500-mg/day) sodium benzoate treatment improved cognitive function in AD patients with excellent safety and that benzoate decreased Aβ burden in an animal AD model. The current study aimed to explore whether oral sodium benzoate was able to reduce Aβ peptides in AD patients and whether Aβ before treatment was correlated with cognitive improvement after treatment. This secondary analysis used data from a double-blind trial, in which 149 patients with mild AD were randomized to receive oral placebo or one of three benzoate doses (500, 750, or 1000
