Jamieson Addresses JAMA Study on Ginkgo Biloba

• Supplements

New research findings published last week in the Journal of the American Medical Association (JAMA) examine standardized Ginkgo biloba extract and, within this study’s narrow focus, provide useful information regarding the herb’s effectiveness.

Gary Leong, Vice President of Scientific and Technical Affairs for Jamieson Laboratories, offers the following clarification and context for these results:

The body of previously published evidence suggests that Ginkgo biloba may help improve cognitive impairment in older adults. So it is important to place this new research in its proper place and remember that ongoing clinical trials may address some of the limitations of the current study. 

Clinical research has already demonstrated that Ginkgo biloba can be used to improve blood circulation and reduce oxidative stress, which are two risk factors associated with the progression of cognitive decline, dementia and Alzheimer’s disease.

There are more than 60,000 cases of dementia diagnosed in Canada each year.¹ As Canada’s population ages, the incident rate of cognitive decline, dementia and Alzheimer’s disease will increase. Yet, the exact causes of these cognitive conditions remains unknown.

There is no magic bullet to prevent or cure cognitive decline. The solution instead will likely lie in a multi-component, integrated approach that supports cognitive wellness through healthy living: following Canada’s Food Guide to maintain a balanced diet; using nutritional supplements, such as Ginkgo biloba; and engaging in both mental and physical exercise. 

It would be unfortunate if this study sent the wrong message to Canadians who have benefited from Ginkgo biloba use. Ginkgo biloba is a safe, effective and natural product for use in a comprehensive cognitive health regime.

Jamieson Laboratories’ Ginkgo Biloba has been approved by the Natural Health Product Directorate of the Health Protection Branch Canada (NPN 80004439). It carries the following approved claims: 

• Helps enhance cognitive function in an aging population
• Helps enhance memory in an aging population, and
• Helps support peripheral circulation. 

Canadians wishing to supplement their diets with this product should discuss their options with a qualified healthcare professional.
