Answer: Ginkgo biloba shows small improvements in attention and memory in some trials of healthy adults and mixed or null results in others, including the largest prevention studies. It supports blood flow in small vessels, is safe for most people at 120 to 240 mg of extract, and must be avoided with blood thinners and before surgery.
- The oldest brain botanical; standardised extract EGb 761 is the studied form.
- Large dementia-prevention trials: no effect. Smaller cognition trials: modest gains.
- Typical dose 120 to 240 mg of extract daily, judged over 6 to 12 weeks.
- Real caution: bleeding risk with anticoagulants and before surgery.
What is ginkgo, and why is it in brain formulas?
Ginkgo biloba is a tree species that has survived essentially unchanged for over 200 million years. Its fan-shaped leaves are extracted for two compound families, flavonoid glycosides and terpene lactones, which relax small blood vessels and reduce platelet clumping. Better flow to the brain is the rationale for every ginkgo memory product, including ours. The NCCIH summary is a fair starting point.
What did the big trials find?
Two large, well-run studies, GEM in the United States and GuidAge in France, gave 240 mg of standardised extract to thousands of older adults for five to six years to see whether it prevented dementia. It did not. That is the honest headline on the strongest evidence, and any page claiming ginkgo prevents Alzheimer's is contradicting it.
Where the smaller studies differ
| Outcome | Finding | Confidence |
|---|---|---|
| Dementia prevention | No effect in large trials | High |
| Attention and speed in healthy adults | Small gains in several short trials | Low to moderate |
| Memory in mild impairment | Mixed; some European trials positive | Low to moderate |
| Circulation markers | Consistent improvement | Moderate |
The pattern: ginkgo is not a shield against disease, but it may sharpen everyday attention modestly in people whose circulation could use help.
Dose and safety
Studies use 120 to 240 mg a day of extract standardised to 24 percent flavonoid glycosides and 6 percent terpene lactones, split or single dose. Side effects are uncommon: headache, stomach upset, dizziness. The one that matters is bleeding. Ginkgo makes platelets less sticky, so combined with warfarin, apixaban, clopidogrel or daily aspirin it can raise the risk of bruising or bleeding. Surgeons routinely ask patients to stop it two weeks before an operation.
How ginkgo is used in NeuroRecall
Ginkgo is one of NeuroRecall's six named ingredients, included for the circulation track of the formula. The amount per capsule is on the Supplement Facts panel of the bottle, and we tell every customer on blood thinners to clear it with their doctor before ordering. That caution sits above the price on the NeuroRecall official website, along with the current NeuroRecall discount.
So should you take ginkgo?
If you are healthy, off anticoagulants and want modest support for attention, it is a reasonable ingredient with a long safety record. If you are hoping it will prevent or treat memory disease, the evidence says look elsewhere: sleep, exercise and blood pressure control have far stronger data, as the National Institute on Aging lays out.

How long does ginkgo take to work?
Trials that found effects ran six to twelve weeks. A single dose does little that you would notice.
Can I take ginkgo with aspirin?
Ask your doctor first. Both reduce platelet stickiness and the effects can add.
Is ginkgo tea the same as extract?
No. Tea delivers far lower and variable amounts, and raw leaves contain ginkgolic acids that extracts remove.
