VINPOCETINE Source: wholehealthmd.com What Is It? Vinpocetine is a derivative of an extract taken from the lesser periwinkle plant (Vinca minor), an evergreen undershrub. The shrub is native to Europe, where it has been been under examination since the 1950s for boosting stroke- and age-related decline in brain function. Only recently has vinpocetine become available in the United States, and not as a prescription drug like in Europe, but as an over-the-counter dietary supplement. Poor brain circulation is one of the most significant mechanisms responsible for the cognitive decline associated with aging-typically, problems remembering names, directions, appointments. Disorientation and memory lapses are common. Research indicates that vinpocetine, like the widely publicized herb ginkgo biloba, can guard against such developments by increasing blood circulation in the brain. This is particularly true for people already suffering from mild, age-related cognitive impairment. Vinpocetine also enhances the brain's use of oxygen by increasing the amount of ATP (adenosine triphosphate, the body's cellular fuel). People suffering from dementia caused by numerous tiny strokes appear to benefit from an increased oxygen-rich brain environment. This condition can cause memory problems that closely resemble those of Alzheimer's disease. Vinpocetine may be able to protect the brain from damage caused by strokes. Extensively studied in Europe, vinpocetine has also been used to treat symptoms of acute stroke, motor disorders, and dizziness. Some studies indicate a possible value for improving visual actuity and hearing as well. Even otherwise healthy people experienced improved short-term memory with taking vinpocetine. General Interaction There are no known drug or nutrient interactions associated with vinpocetine. Cautions In most clinical trials, there have been no serious side effects related to the use of vinpocetine. In rare cases, adverse reactions do occur. These can include a temporary drop in blood pressure, an accelerated heart rate, dry mouth, and weakness. Stop taking vinpocetine and consult your doctor if this occurs. Dosage 10 mg, twice a day |
