Taking Gingko Biloba Does Not Improve Memory Study Finds

How Ginkgo Biloba Improves Memory
University of Hertfordshire
Taking Gingko biloba supplements does not improve memory, attention or problem solving in healthy individuals, according to a new study.

Taking Gingko biloba supplements does not improve memory, attention or problem solving in healthy individuals, according to researchers from the University of Hertfordshire.

The paper, published in Human Psychopharmacology: Clinical and Experimental, is the first meta-analytic review examining the effects of Gingko biloba on healthy people across all age groups. The researchers led by Professor Keith Laws found zero impact on the cognitive functions whatever the age of the people, the dose taken or the length of time of taking Gingko biloba supplements.

Gingko biloba, the oldest tree living species, has been used extensively in traditional Chinese herbal medicine for thousands of years. Today, it is one of the most widely used plant-based products available without prescription in Europe and North America, where is it marketed as a dietary supplement to treat blood disorders and, more specifically, to enhance memory both for healthy individuals and also for those trying to ward off Alzheimers Disease.

Our findings show that taking Gingko biloba supplements at any age to boost memory have no impact at all and may be a waste of time and money.

Boosts Brain Function And Memory

Ginkgo biloba extract contains a rich amount of antioxidants that improve blood flow to the brain in healthy people. Improved blood circulation in the brain reduces the risk of damage to neurons, leading to improved performance.

As a modest number of studies have found out, there is a link between using ginkgo biloba and increased mental performance and well-being .

While these findings have led many people to believe that ginkgo biloba extract can improve their focus, attention, and memory, further research shows otherwise. There is no measurable increase in memory, brain function, or attention capacity from using ginkgo biloba supplements .

Some users may enjoy this benefit from using ginkgo biloba extract while others may not.

Studies have shown that ginkgo biloba is best used together with ginseng to get better results in mental clarity. There is evidence that ginkgo leaf extract used in combination with American ginseng showed improvement in ADHD symptoms such as anxiety, hyperactivity, and impulsivity in children age 3 to 17-year-old.

The herb is generally well-tolerated, but due to multiple case reports of bleeding, it should be used cautiously in patients on anticoagulant therapy and those with known blood clotting disorders, or prior to surgical or dental procedures.

Ginkgo biloba may interact with certain medications as well. Please consult your physician before starting ginkgo biloba extract supplement if you are taking any prescription medication for diabetes, blood pressure, seizure, etc.

Asian ginseng may overstimulate younger children. If this happens to your child, switch to American ginseng.

Ginkgo Doesn’t Work: Are There Better Ways To Save Your Brain


  • Study: No evidence that ginkgo biloba reduces normal, age-related cognitive decline
  • Last year, same researchers found ginkgo doesn’t impact dementia, Alzheimer’s
  • Other ways to keep brain healthy: exercise body and mind, eat right and manage stress


— Ginkgo biloba has failed — again — to live up to its reputation for boosting memory and brain function. Just over a year after a study showed that the herb doesn’t prevent dementia and Alzheimer’s disease, a new study from the same team of researchers has found no evidence that ginkgo reduces the normal cognitive decline that comes with aging.

Should you take ginkgo to slow down the effects of age on the brain? “The answer appears to be ‘no,'” says the lead author of the study, Steven T. DeKosky, M.D., the vice president and dean of the School of Medicine at the University of Virginia.

In the new study, the largest of its kind to date, DeKosky and his colleagues followed more than 3,000 people between the ages of 72 and 96 for an average of six years. Half of the participants took two 120-milligram capsules of ginkgo a day during the study period, and the other half took a placebo.

The people who took ginkgo showed no differences in attention, memory, and other cognitive measures compared to those who took the placebo, according to the study, which was published in this week’s Journal of the American Medical Association.

Supplement Industry Says It Polices Itself

Mister said that the council has committed $1.5 million for an eight-year program at the Better Business Bureaus National Advertising Division to scrutinize supplement advertising and issue decisions on when supplement sellers should change or pull advertising claims. When a company ignores a National Advertising Division decision, the division refers the ads in question to the Federal Trade Commission.

This is a good example of industry trying to police itself, he said.

But Mister said the council also supports the FDAs oversight of the industry. It has repeatedly asked, he said, for the Food and Drug Administration to be provided with more resources so it they can enforce a 1994 law that allows the FDA to remove a supplement from the market when the agency can show that the product is not safe.

Claims for Gingko, Ginseng and Garlic Discredited by GAO

The GAO found cases of deceptive marketing or questionable claims tied to Ginkgo biloba, ginseng, garlic and chamomile, according to Kurtzs testimony. The GAO did not disclose the names of the herbal supplement marketers it investigated, but Kurtz said that all cases of deceptive or questionable marketing and inappropriate medical advice have been referred to the Food and Drug Administration and the Federal Trade Commission.

The GAO said it found herbal supplement sellers making the following deceptive claims:

Claim: Garlic prevents obesity and diabetes and cures cardiovascular disease.

Why Taking Ginkgo Biloba For Memory Is Controversial

Clearly, Ginkgo biloba is an extremely popular memory aid, but recently ginkgos effectiveness has come into question.

With a history of thousands of years of use in China and the backing of modern medicine in Europe, it may seem puzzling that the benefits of ginkgo are in doubt.

Heres a little background on how this came about.

In the 1980s, a German pharmaceutical company launched its first ginkgo product, an extract called EGb 761.

EGb 761 was found to improve mental functioning, but only in elderly adults with dementia, not in healthy adults.

Manufacturers of ginkgo supplements erroneously used this piece of news as proof that ginkgo improves memory and other cognitive functions in all adults.

Of course, this is not a scientifically valid extrapolation.

Heres what two major studies concluded about ginkgo as a memory supplement in cognitively healthy adults, i.e., those not diagnosed with dementia or Alzheimers.

Ginkgo Evaluation of Memory Study

The Ginkgo Evaluation of Memory Study is the largest clinical trial performed to date to evaluate ginkgos effectiveness on mental decline.

This study followed over 3,000 seniors with normal cognition or mild cognitive impairment over a period of eight years.

Researchers found no evidence of improvement in cognitive decline in general, or of memory, attention, visual-spatial construction, language, or executive functions.

Ginkgo Biloba May Protect Memory: Study

Ginkgo Biloba for Memory

3 Min Read

NEW YORK – Taking the herbal supplement ginkgo biloba may help delay the onset of cognitive impairment in normal elderly adults, according to a study published online Wednesday.

However, the study also showed a higher incidence of strokes and mini-strokes in ginkgo users. The reasons for this are unclear and require confirmation in other studies, the investigators say.

Extracts of ginkgo biloba are among the most widely used dietary supplements. The herb is marketed as a memory enhancer, and some studies have suggested it may help improve memory and other mental functions in people with dementia.

One of the most pressing public health problems facing our society is the rapidly growing number of people who, due to their age alone, are at high risk of developing dementia. The potential to delay or prevent this is of great importance, study chief Dr. Hiroko H. Dodge, from the Oregon State University in Corvallis, said in a statement.

The three-year study involved 118 people age 85 and older with no memory problems. Half of them took ginkgo biloba extract three times a day and half took a placebo.

During the study, 21 people developed mild memory problems, or questionable dementia: 14 of those took the placebo and 7 of those who took the ginkgo extract. Although there was a trend favoring ginkgo, the difference between those who took ginkgo and those who took placebo was not statistically significant.

Reduces Symptoms Of Dementia And Other Psychiatric Diseases

Ginkgo has undergone multiple studies on its ability to fight symptoms associated with Alzheimers disease and impaired cognitive function. However, medically reviewed research shows conflicting results.

Many studies have shown a decrease in the rate of cognitive decline in older people, although other studies could not come to similar conclusions.

However, a review of 21 medically reviewed studies has shown an increase in the functional capabilities of mild Alzheimers disease patients who use ginkgo with conventional medicines .

Other studies show a significant reduction in the severity of symptoms associated with mild cognitive impairment, where a patient used ginkgo for up to 24 weeks .

Ginkgo bilobas ability to increase blood flow to the brain draws these positive results, especially in cases of vascular cognitive impairment .

While more research is underway to determine if ginkgo is effective at treating cognitive decline, its benefits are quite clear in assisting treatment.
