Dementia
Supplements studied for dementia.
Overview
No supplement here shows clear treatment benefit for established dementia. Melatonin (WA 56; low effect size, very high evidence, medium trust; 10 studies) did not improve cognition or daily behavior in most trials, though low-dose nightly use may ease sundowning in some studies.
Green Tea, Caffeine, and Black Tea appear mainly in observational prevention research with low trust. Higher green tea intake and midlife caffeine consumption have been linked to lower later dementia risk in some cohorts, but findings are not consistent across populations. Branched Chain Amino Acids (BCAAs) blood levels correlate with lower risk in one analysis. See the heatmap and evidence reviews below.
