Nootropics Raw Powder Vincamine For Brain Improvement CAS 1617-90-9 Anasclerol
Product Name: Vinpocetine
CAS No.: 42971-09-5
Molecular Formula: C22H26N2O2
Molecular Weight: 350.454 g/mol
Appearance: White Crystalline or slightly yellow Powder
Solubility: Practically insoluble in water, soluble in methylene chloride, slightly soluble in anhydrous ethanol.
(1) Vinpocetine is a cerebrovascular expansion drug and has a relatively stronger function than Vincamine. It can selectively increase cerebral blood flow, enhance and improve brain oxygen supply, promote metabolism, enhance the capacity of deformation for red blood cells, reduce blood viscosity, inhibit platelet aggregation, improve tissue metabolism.
(2) Vinpocetine is mainly used in the treatment of cerebral infarction sequela, cerebral hemorrhage sequelae, cerebral arteriosclerosis, etc. It can also used in the treatment of retinal vascular sclerosis and blood vessel spasm, the elderly deafness, and dizziness.
(3) Vinpocetine is a half synthetic Vincamine derivative, and has the similar effect with Vincamine. It has a stronger expansion function for cerebrovascular selectively.
1. It has vasodilating, blood thinning, and memory-enhancing actions.
2. It acts as a cerebral stimulant and vasodilator.
3. It is used to treat arteriosclerosis.
4. It is very effective in curing dementia caused due to insufficient blood supply to the brain.
5. It interferes with cells' ability to synthesize DNA and RNA.
Typical doses of Vinpocetine range from 5 to 20 mg per day,but you will find 5 mg of Vinpocetine and this is typically enough for most people to achieve their desired effects.
Vinpocetine can be an effective nootropic taken alone, but it is known to work very well in combination with other nootropics and is often found in preformulated supplements. If you prefer to make your own nootropic stack, here are some ideas for a good starting point.
Vinpocetine and Ginkgo Biloba Stack for Long-Term Cognitive Enhancement
Vinpocetine and Ginkgo Biloba act as potentiators for each other, with the combination of the increasing the overall potency and effectiveness of both. This simple stack will boost cognitive abilities, improve mood, and increase motivation and productivity.
3x per day
5 mg Vinpocetine
50 mg Ginkgo Biloba
Vinpocetine and Racetam Stack for Studying
This stack will make the most of intensive study time; the piracetam will work with the vinpocetine to improve general cognition, the aniracetam will boost memory, and the Alpha GPC will ensure sufficient high-quality choline for transformation to acetylcholine, the "learning neurotransmitter."
2x per day
1 g Piracetam
200 mg Aniracetam
5 mg Vinpocetine
300 mg Alpha GPC

Cerebrovascular drug. A alkaloid extracted from apocynaceae plant, Vincamine derivatives. Selectively inhibit vascular smooth muscle calcium dependency phosphodiesterase, and increase the content of cGMP, expanse cerebral vascular, which in turn increase cerebral blood flow, improve cerebral circulation, but has little effects on the cardiovascular and blood pressure. Effectively, good tolerance, less adverse reaction. Used for dizziness, headache, memory disorders, movement disorder, aphasia, hypertensive encephalopathy, etc.. Can also be used in brain blood circulation obstacle caused by mental or neurological symptoms.
1) Inhibit the activity of calcium dependency phosphodiesterase, increase the content of cAMP which can relax vascular smooth muscle, then relax vascular smooth muscle, and further increase cerebral blood flow.
(2) Enhance the capacity of deformation of red blood cells, reduce blood viscosity, inhibit platelet aggregation, and thus improve blood flow and microcirculation.
(3) Promote the brain tissue to absorb glucose, and promote the transformation of brain monoamine metabolism.
(4) Inhibit the increase of brain lactic acid during cerebral ischemia, increase the ATP content, inhibit the generation of lipid peroxide in the brain, delay the occurring of spasm caused by cerebral ischemia, have the function of improving cerebral metabolism and protecting brain.
