Beetroot (Dietary Nitrate) for Poor Memory
Proposed to work via nitric-oxide-mediated increases in cerebral blood flow, though direct evidence for this pathway improving memory in humans is thin.
How strong is the research?
No Benefit evidence
13 weeks of nitrate-rich beetroot juice, at any of three incremental doses, did not change cognitive function or cerebral blood flow versus a nitrate-depleted placebo in overweight/obese older adults.
