Take before noon it acts as a stimulant. Neuroprotective effects: Rhodiola root extract appears to inhibit the activity of monoamine oxidase B (MAOB) in vitro, which suggests that it may have protective effects against MAOB-related neurodegenerative diseases such as Parkinson's disease or Alzheimer's (71211). Animal research suggests that rhodiola extract protects against cognitive deficits and neuronal injury caused by intracerebroventricular streptozotocin in a rat model of Alzheimer's disease. This effect has been attributed to the antioxidant activity or rhodiola (71241).

Salidroside, a constituent of rhodiola, appears to protect against beta-amyloid-induced oxidative stress in human neuroblastoma cells, suggesting that it may help prevent or treat neurodegenerative diseases such as Alzheimer's disease (71253).

That's from theraputic natural database. I also like ginkgo for cognition. You can purchase a tincture and add to tea etc.
