For thousands of years, leaves from the Ginkgo biloba tree have been a common remedy in Chinese medicine. Nutricost's Ginkgo Biloba Extract is always from the finest quality available worldwide.

Ginkgo supplements are generally considered safe. However, in some individuals, they can cause nausea, headache, dizziness, and diarrhea. If you take any other supplements or medicines regularly, talk to your health care professional before you start ginkgo supplementation.
