Vinpocetine And Brain Health
Vinpocetine is a derivative of an organic compound found in the plant species Vinca minor, or common periwinkle. It is best known for its neuroprotective effects and used in Europe and Japan in treatment of age-related cognitive decline. More often than not, its activities inside the human body are described as vasodilator, which means it increases blood flow. It has also seen a growing presence in the North American market as a dietary supplement.
Vinpocetine is available as a prescription drug in certain European countries and Japan and has shown to be speed up prognosis of patients who suffered cerebrovascular accident, or CVA, which is commonly referred to as stroke. Most cases of cerebrovascular accident are brought on by ischemia, or very poor circulation of blood to certain parts of the brain. This is exactly what vinpocetine is beneficial for, and recommended dosages have so far yielded very encouraging results.
Improves Blood Circulation in the Brain
It has long been postulated that one of the mechanisms of action of vinpocetine is limiting the effects of Na+ channels that are sensitive to voltage. This creates a neuroprotective effect believed to contribute to mental clarity and sustained attention. Striatal nerve endings produce extracellular Ca+ ions that induce neuronal damage through a phenomenon called excitotocity. High levels of Ca+ ions are now alleged to be correlated with voltage-sensitive Na+ channels. Striatal nerve endings see a decline in Ca+ ions when Na+ channels are influenced by vinpocetine, and in the process lessen excitotoxicity.
Attenuates Ischemic Neuronal Damage
In addition to limiting neuronal damage induced by excitotoxicity, which in turn results from cerebral ischemia, vinpocetine plays an active role in the upkeep of brain cells after being subjected to ischemic damage. As a vasodilator, it not only counters the effects of ischemia but also significantly increases the brain’s access to bioactive molecules like oxygen and other nutrients exclusively distributed by the circulatory system.
It also inhibits the enzyme phosphodiesterase, which is specialized for the breakdown of cyclic adenosine monophosphate, or cAMP, and cyclic guanosine monophosphate, or cGMP. By so doing, vinpocetine contributes to glucose metabolism and energy production in the brain, and at the same time, improves the distribution of bioactive compounds in the central nervous system.
Displays Neuroprotective Activities
Vinpocetine and its precursor belong to a group of indole alkaloids known as tryptomines, which are present in the human brain and the rest of the central nervous system in minute quantities. These organic compounds make up several psychoactive drugs and in the human body act as neuromodulators and neurotransmitters in the form of melatonin and serotonin.
Vinpocetine in particular displays activities that are primarily anti-inflammatory in nature. Several studies point to its effects on the enzyme complex called IkB kinase, which regulates cellular responses to inflammation, by preventing the translocation of a protein complex called responsible for the process of inflammation within cells.
In a Nutshell, vinpocetine can help you think clearer and protect the brain from inflammation and free radical damage. Give vinpocetine a try today!
