Vinpocetine Mode of Action
Vinpocetine’s cognitive and memory benefits may be related to its ability to increase blood circulation in the brain, decrease the rate of neuronal death, improve intracerebral glucose, and produce long-term potentiation in the hippocampus (2). Memory improvement is also believed to be from inhibition of sodium and calcium channels and modulating noradrenergic activity in the brain (1).
Vinpocetine is believed to inhibit platelet aggregation and is therefore not recommended for those with bleeding disorders, or blood-clotting disorders because it may increase the risk of bleeding. Other functions involving blood flow is improved red blood cell formation and improving microcirculation in the brain, leading to increased cerebral blood flow. It may also protect neurons by preventing a loss of oxygen, due to the increased amount of red blood cells carrying oxygen that is available to the brain (2).
The nootropic benefits of Vinpocetine may be caused by cholinergic activity, modulation of norepinephrine effects on cyclic adenosine monophosphate (cAMP, a messenger in the signal transduction pathways), and increased brain catecholamines (2, 3).
Vinpocetine's bioavailability is significantly increased by taking it with a meal and raises the absorption rate up to 60-100% (2).
Pure Nootropics’ Vinpocetine provides 20 mg of Vinpocetine (extract from the whole periwinkle plant) per 1 capsule. Suggested use for adults is 1 to 2 capsules by mouth daily, or as directed by your healthcare practitioner.
