It seems to be the second failed attempt to show that supplement ginkgo biloba is able to prevent Alzheimer's disease. The study, which is based on the assessment of approximately 3,000 people, will be published in the journal Lancet Neurology.

The study has revealed that the study researchers have closely followed elderly people, who were having problems in regard to their memory. The experiment took place in France and continued for more than five years. The total number was divided into two sub-groups in which one group was asked to take the supplement and the other group was given placebo.

Study researchers were of the view that they did not find any difference in any of the groups. As said earlier, it is not the first time when an experiment has been taken out in regard to the supplement.

Previous study in regard to the supplement ginkgo biloba was being carried out in the US. The study was being carried out for six years, but no difference was found, which could prove that the supplement prevents Alzheimer's disease or is beneficial in reducing memory related problems.

"This supplement has been studied as extensively as any drug, with no evidence that it improves memory”, said Lon Schneider, who is an Alzheimer's researcher.
