What is Vinpocetine? Vinpocetine is a semisynthetic derivative alkaloid of vincamine, and also can be semisynthesized from tabersonine, an extract from Voacanga Africana Seed. Clinical studies suggest that it facilitates cerebral metabolism by improving cerebral blood flow, increasing glucose and oxygen utilization by neurons and concentration of neurotransmitters involved in the process of memory formation.   Clinical studies have also shown that Vinpocetine may help to maintain healthy microcirculation in the inner vital organs of ears and eyes. Research has shown that the effects of this compound go beyond mere prevention and turn it into a Powerful Memory Enhancer.

Application of Vinpocetine

1. Vinpocetine increases blood flow;
2. Vinpocetine increases the rate at which brain cells produce ATP (which is a cell molecule that creates energy);
3. Vinpocetine speeds up the use of glucose in the brain, regulates Sodium/ Potassium channels.
4. Vinpocetine speeds up the use of oxygen in the brain.
5. Vinpocetine increases levels of neurotransmitters involved in memory.
 

Function of Vinpocetine

1. Vinpocetine is chemically related to, and derived from vincamine, an alkaloid found in the periwinkle plant.
2. Vinpocetine was introduced into clinical practice in Europe more than two decades ago for its role in 
cerebrovascular disorders and related symptoms. 
3. Experiments with this periwinkle extract indicate that Vinpocetine can dilate blood vessels, cross the
blood-brain barrier, enhance circulation in the brain, improve oxygen utilization, make red blood cells
more pliable,and inhibit aggregation of platelets.
