Notes
grade-b Minor Very High See all 5 studies
Cognitive impairment that is associated with Alzheimer's appears to be significantly reduced with ginkgo supplementation.
grade-c Notable - See study
At least among nutraceuticals, Alpha-GPC appears to significantly improve cognition in persons with Alzheimer's disease at the dose of 1,200mg when taken as a daily supplement over a prolonged period of time.
grade-c Notable Very High See 2 studies
Very high dose Vitamin E supplementation in the form of α-tocopherol (2,000 IU) appears to reduce the rate of cognitive decline in persons with moderate to severe Alzheimer's Disease with a potency comparable to selegiline. Currently no research on lower (more standard) doses, and there appears to be no influence on minor AD or cognitive decline not characterized by AD.
