3. How to Take Ginkgo Biloba?
Ginkgo is available in capsule form, as tablets, liquid extracts, and as dried leaf for teas, so it’s a matter of taste and convenience.
There is no standard dose of Ginkgo Biloba supplements. The evidence seems to support the safety of taking 120–240 mg divided into several doses throughout the day. Ginkgo Biloba is taken orally and it should be taken with meals.
Do not eat fresh (raw) or roasted Ginkgo seeds. These can be poisonous and have serious side effects.
Remember, it can take up to six weeks before you begin to notice any effects.
As with any herbal supplement, there are risks involved. Ginkgo could lead to serious health complications if you are allergic or taking certain medications.
