Neuronutraceuticals for Alzheimer's Disease Treatment: A Systematic Review of Randomised Controlled Trials Over the Last 20 Years

open access: yesPhytochemicals in Food and Medicine, Volume 1, Issue 1, March 2026.
This PROSPERO‐registered review analysed 37 RCTs on neuronutraceuticals for Alzheimer's disease. Despite diverse targets—amyloid/tau, inflammation, oxidative stress, metabolism, synaptic plasticity, cholinergic and hormonal—the evidence was of low quality. RoB2 flagged attrition (86.5%) and reporting bias (81%). Current data do not support clinical use;
