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 Alzheimer’s Disease.
Thirteen randomized control trials were used in this meta-analysis. While we should be wary of meta-analyses that show positive results, if the results are null, then it is more likely reliable because the results have NOT been shown to evidence of ANY positive effect.
Other recently published studies shown that there is also no evidence to support Gingko biloba supplements to protect against developing Alzheimer’s Disease.
You are likely wasting your money.
Unsatisfying results have also come from research into fish oil. It’s not bad for you but it may not be worth it.
