There is currently no standard recommended ginkgo dosage. In studies, doses of 120 mg to 480 mg daily have been used. However, it is not known whether these are the most effective and safest ginkgo doses, so it is a good idea to follow the directions on your particular ginkgo product. If you develop any side effects while taking ginkgo, it may be a sign that your dose is too high.
An Introduction to Ginkgo DosageIt is important to note that unlike medications (for which the standard doses have been well established), there is less information available for determining the best dose for supplements, including ginkgo (ginkgo biloba).
Reasonable Ginkgo DosingClinical studies have often used ginkgo dosages of 120 mg to 480 mg per day, usually taken in two or three smaller doses. It is a good idea to start with a low dose (120 mg per day or less), to avoid stomach upset. In all cases, be sure not to exceed the recommended dose on the label of your particular product.
If you develop bothersome or serious ginkgo side effects, check with your healthcare provider right away. These side effects may be a sign that your ginkgo dose is too high. Taking too much ginkgo can cause serious problems, including dangerous (even fatal) internal bleeding.
Ginkgo contains a toxin known as ginkgolic acid. This toxin can cause severe allergic reactions and may be carcinogenic (may increase the risk of cancer). Make sure your ginkgo supplement contains less than 5 ppm (parts per million) of ginkgolic acid.
- Because the manufacturing of supplements (such as ginkgo) is not closely regulated, it is important to choose a reputable manufacturer for ginkgo supplements. It is a good idea to look for the "USP" symbol, as this means that the supplement has been tested and contains the right ingredients in the right amounts. Reputable manufacturers are more likely to check the toxin levels of their products.
- If you have any chronic health problems or take any prescription medications, it is probably a good idea to check with your healthcare provider before taking ginkgo.
- If you are unsure about anything related to your dosage or ginkgo dosing in general, please talk with your healthcare provider.
