Vinpocetine, a derivative of the alkaloid vincamine, is an extract
from the seeds of the periwinkle plant. It has a long history of
use as a traditional tonic to alleviate weariness, especially the
type associated with advanced age, and also as an astringent for
excessive menses, bleeding gums, mouth sores, and more.
Throughout the world, vincamine has been used to treat senile
dementia with significant success. Studies have found vinpocetine
to demonstrate many of the same functions as those of vincamine,
but without the side effects. Moreover, it has been shown to be at
least two times (and up to three or four times) more potent than
vincamine for improving cerebral circulation, memory, and other
functions in humans. No interactions with pharmaceutical drugs have
Vinpocetine is a biosynthetic nootropic that acts as both a brain
booster and neuroprotectant. It's known for enhancing cognition,
sharpening memory, and even improving mood, and it's safe,
well-tolerated, and free of side effects. Vinpocetine is new to
many nootropic users, but for anyone who's interested in thinking
and feeling better it's definitely worth a second look.
Numerous scientific studies have shown vinpocetine to be of benefit
for the prevention and improvement of many different kinds of
ailments. It enhances cognitive functions, including those
involving long- and short-term memory, and it has also been shown
to be valuable in protecting heart, visual, and hearing functions,
among other benefits.
In broadest terms, vinpocetine is a powerful memory enhancer. It
achieves this principally by facilitating cerebral metabolism and
improving blood flow in the brain. It works by causing mild
dilation of blood vessels, thereby allowing for increased cerebral
blood flow, which results in increased oxygenation and glucose
This makes vinpocetine an ideal candidate not only for the
improvement and prevention of certain disease processes in need of
increased blood flow and oxygenation, but also for athletes who
want to enhance their performance by increasing brain oxygenation,
such as skiers, mountain climbers, and high-altitude hikers.
In addition to more efficient brain circulation, vinpocetine has
been found to increase brain-cell energy through its effect on the
production of ATP (the cellular energy molecule).
Since many brain disorders have been found to be caused by poor
circulation or by neuronal damage due to inadequate oxygen and
inadequate amounts of energy, it makes sense to consider
vinpocetine in one's daily cognitive supplement program.
Vinpocetine is taken in the daily dosage range of 15-60mg, divided
into three daily doses with meals. The standard low dose is 5mg at
each of these three meals, with 20mg at each meal being seen as the
higher end of efficacy. These doses are taken for the purposes of
neuroprotection, enhancing cerebral blood flow, and reducing the
rate of cognitive decline.
Doses in the higher end of that range (30-45mg acute dosages) may
be useful for promoting cognition and memory formation in otherwise
healthy persons, but there is not a lot of evidence looking at this
