Background
Vinpocetine comes from the plant Vinca minor. Itâ??s been used as a pharmaceutical in Europe and Japan for over 20 years to treat cerebrovascular diseases under the trade names Cavinton and Intelectol. In the U.S., scientists have actually been researching its benefits in patients that have had strokes. Even though the verdict is still out, there have been some very positive studies that have been published supporting its use as adjunct treatment for strokes.
How it works
Scientists have found numerous different ways in which vinpocetine not only has neuroprotective effects, but also cognitive-enhancing effects. Some of them include:
Its ability to inhibit sodium channels within brain cells thereby protecting the cells from hypoxia (lack of oxygen)
Its ability to inhibit phosphodiestarase type 1 leading to an increase in the concentration of cyclic AMP which is thought to result in its vasodilator effects
Its ability to counteract the effects of free radicals
Its ability to protect the brain cells from the excitatory neurotransmitters glutamate and NMDA
Its ability to inhibit cerebral platelet aggregation
Its ability to enhance cerebral metabolism through two potential mechanisms: increase in oxygen utilization and an increase in glucose uptake.
Its ability to increase cerebral blood flow
Thus, as you can see, it has a wide range of neuroprotective and neuro-enhancing benefits.
Dosage
Because its half-life is relatively short, its recommended dosage is 10mg three times per day. Dosages of 20mg three times of day have been used with success and minimal side effects. Like always, find the dose that works the best for you.
Food has been shown to increase its absorption by up to 100%. Always take it with food.
Warning: Because of its ability to inhibit platelet aggregation, it should not be used if youâ??re taking warfarin or any other blood thinning agents.
Why I like it
More blood flow + more glucose uptake + more oxygen utilization = more mental energy
PET scans (positron emission topography) have actually shown that vinpocetine has a particular affinity to improve cerebral blood flow more than systemic blood flow. In addition, itâ??s also been shown to increase cerebral metabolism (mental energy) by not only enhancing glucose uptake by brain cells, but also increasing oxygen utilization by brain cells. Now that is impressive. Viagra for your brain.
Side note: PET scans are just a nifty little way scientists can actually look at how the brain functions without cracking open your skull. Itâ??s almost like watching your brain work on a TV screen.
Not only does it have cognitive-enhancing capabilities, but its multitude of ways in which it protects the brain is even more impressive. Itâ??s basically the aspirin of neuroprotection. Too many free radicals? Check. Too many excitatory neurotransmitters? Check. Atherosclerosis decreasing blood flow to the brain? Check.
Why for poker players
I strongly believe vinpocetine should be in every daily regimen for people that rely on mental performance for their jobs. Poor diet. Poor sleeping habits. Too much stress. Too much pollution. All of these things have a cumulative negative effect on mental performance. Your brain needs help.
Its ability to selectively increase cerebral blood flow as opposed to overall blood flow is enough evidence alone to use it. Oxygen and glucose are the two most critical ingredients to mental energy. Without either, youâ??re a vegetable. Vinpocetine provides more of both. Thatâ??s the one-two punch to landing a knockout with mental performance.
Iâ??ll post the PET studies along with others tomorrow.
