Extra Strength Ginkgo is derived from the Ginkgo biloba tree leaf. Thriving on Earth for more than 200 million years, the Ginkgo tree is the world's oldest living plant. Considered sacred in the Orient, Ginkgo was the only surviving tree near the epicenter of the Hiroshima atomic bomb blast. One specimen, planted near a Japanese monastery more than 1,000 years ago, is still alive today.* Ginkgo biloba extracts rank high among the most popular herbal products in Europe, where sales exceed $500 million annually. Ginkgo biloba extract is non-toxic, free of side effects, and safe for continuous use at the recommended intake level. Best Ginkgo Extract should be taken for four weeks or more before results can be expected.* Rich and Concentrated
The Ginkgo biloba leaf is rich in phytonutrients, chiefly flavonglycosides and terpene lactones (ginkgolides). In the extract, these bioflavonoid-like active ingredients are highly concentrated. Fifty pounds of Ginkgo leaves are used to yield one pound of extract.* Supports Brain and Cognitive Function*
Numerous clinical studies have been published on Ginkgo biloba extract. Much of this extensive research deals with Ginkgo’s beneficial effects on the brain and mental function. Foremost among its actions, Ginkgo biloba extract supports circulatory function in the brain. Enhanced blood flow to the brain means better delivery of oxygen and nutrients. The clinically observed benefits of Ginkgo biloba extract include improved short-term memory and a positive effect on mood, sociability, thinking ability and hearing.* Powerful Antioxidant
Ginkgo biloba extract is a powerful antioxidant. Acting as free-radical scavengers, Ginkgo’s flavonglysosides help prevent damaging peroxidation of cell membrane lipid components.* Improves Circulation
Ginkgo supports circulation in the extremities as well as the brain. By maintaining blood flow in the extremities, Ginkgo biloba extract supports oxygen delivery to tissues and promotes the ability to walk without discomfort. In addition, ginkgolides have been shown to inhibit Platelet Activating Factor (PAF). Controlling PAF reduces clumping of blood platelets and improves circulatory health.*

Q. What are your capsules made of?
A. Doctor's Best capsules are typical gelatin capsules, with the exception of select products now available in veggie cap form. They are made of gelatin from cattle, like the familiar "Knox gelatin" sold in grocery stores.
The gelatin used to make Doctor's Best's capsules is manufactured in accordance with strict guidelines that ensure it is BSE-free. The FDA and the supplement industry approved these guidelines. The gelatin is made only from cattle living in non-BSE countries. All Doctor's Best capsules are in full compliance with the FDA's September 1997 industry guide, The Sourcing and Processing of Gelatin to Reduce the Potential Risk Posed by Bovine Spongiform Encephalopathy in FDA-Regulated Products for Human Use.
Q. How long does it take for a capsule to dissolve?
A. Approximately 30-45 minutes. For 2-piece gelatin capsule, the USP standard for maximum dissolution time is 45 minutes.
Q. How long does it take for a tablet to dissolve?
A. FDA Rules & Regulations require tablets to dissolve in 45 minutes or less. However, Doctor's Best sets its standards higher. They require that their tablets dissolve in 30 minutes or less. Every lot of products in tablet form is tested to verify that it dissolves in under 30 minutes.
Q. Can I find out how fast a capsule or tablet dissolves by dropping it in a glass of water or vinegar at home?
A. Testing dissolution times at home using vinegar is not an accurate way to learn what happens to capsules and tablets in your stomach. Because stomach acid is much stronger than vinegar, capsules and tablets dissolve much faster in the stomach than in a glass of water or vinegar. Also, the stomach continually "agitates" its contents, much like a washing machine does. |

Q. Who determines what the daily dosage should be? And how is this done?
A. A panel of scientists at The Natural Academy of Sciences performs extensive research, ongoing clinical studies and scientific testing in order to determine the RDI (Recommended Daily Intake).
Q. I see that Silicon Dioxide has been used as an excipient in some of your products. Should I be concerned?
A. Silicon Dioxide is a GRAS (Generally Recognized As Safe) food additive. Numerous studies have found the following:
The oral toxicity for humans would be greater than 350 grams in one dose based on allometric comparisons between the mice studied and humans.
A single dose of 2,500mg of amorphous polymeric silicon dioxide to human volunteers did not significantly raise the SiO2 excretion in the urine. This suggests poor absorption of silicon dioxide (Langendorf 1966).
Less than one one-hundredth (1/100th) of the dose was found in urine, suggesting extremely poor absorption (Langendorf 1966).
This would suggest that there is no scientific reason to eliminate silicon dioxide as an excipient at the very low levels found in dietary supplements.
Q. Why is silicon dioxide used as an excipient in Doctor’s Best products? Why are excipients used at all?
A. Silicon Dioxide is used as a flow agent to enable "sticky" substances to flow through the encapsulation equipment. If silicon dioxide were not used, other flow agents would have to be used which would actually increase the number of excipients found in a given product. Ideally, the fewer excipients used, the better.
Q. Is there a limit to how many vitamins can be taken safely in one day?
A. Our bodies need vitamins and minerals, and if taken in large amounts, vitamins and minerals can adversely affect health. Large amounts of anything can be toxic. Our best advice is to work with a nutritionally aware doctor and follow label directions. |

Abstract: 112 patients (51 men, 61 women: mean age ±70.5 8.7 years, range 55-94 years) with chronic cerebral insufficiency were treated as outpatients in several German test centers with Ginkgo biloba extract at 120 mg/day in an open one-year trial. Results showed a statistically significant (P < 0.001) regression of the major symptoms of vertigo, headache, tinnitus, short-term memory, vigilance and mood disturbance. Heart rate and blood pressure modifications were not detected. Laboratory mean levels of blood cholesterol and triglycerides remained practically unchanged during the period of the trial. Significant side-effects did not occur throughout the study, nor were significant interactions with existing basic medications such as cardiac glycosides or antidiabetics observed.

Abstract: Electroencephalography is the only convenient method for functional exploration of the brain. The recent introduction of signal analysis techniques has given it a quantitative dimension and has resulted in pharmacological studies of electroencephalograms. In four studies of this kind, the effects of Ginkgo biloba extract were investigated on three pathological animal models, in healthy young volunteers and in elderly people with demential disorders. In man, the EEG tracings could be analyzed in relation to different psychometric tests. The results obtained confirm those of clinical trials, and notably the activity of Ginkgo biloba extract on alertness.
