Clayton's Health Facts: Vinpocetine.

Clayton South, SPN (ISSA), is a recognized expert in the bodybuilding / fitness industry with over 150 bodybuilding, fitness and nutrition publications to his credit.
What is it and where does it come from?

Vincamine is found in the leaves of Vinca minor (lesser periwinkle) plant, and is a precursor to vinpocetine - potent pharmaceutical that has many positive effects on the brain and body.

What does it do and what scientific studies give evidence to support this?

The benefits observed from vincamine supplementation are attributable to the substance to which it converts in the body: vinpocetine.

Vinpocetine increases blood circulation1,2 and oxygen flow to the brain.3,4 Animal studies have demonstrated that vinpocetine can reduce brain cell death that can result from decreased blood flow to the brain.5

Vinpocetine is a powerful antioxidant6 and it also enhances the delivery of glucose to the brain.7 Glucose is the brains primary fuel source, and without it the brain will shut-down. If glucose delivery to the brain is terminated or severely decreased, one can lose consciousness and fall into a coma.

Clinical research has demonstrated that vinpocetine can help treat the early stages of cerebrovascular disorder8 - a disorder of the brain characterized by blood flow irregularities. This disease can result in decreased brain function, personality disorders, and mental retardation.

Because of its ability to protect the brain and enhance brain function9,10, vinpocetine and its precursor vincamine are effective at treating patients with early-onset dementia.11 They can also help treat some cases of clinical and situationally dependant depression.12

In research, the clinical results of administration pointed to continuous improvement in individual symptoms of depression. Continued supplementation led to high remission percentages. Most importantly, and unlike many commercial pharmaceuticals, very few cases of side-effects were reported.13

Not surprisingly, athletes who supplement with vincamine report significant improvement in visual acuity, memory and focus. Vincamine supports the brain and improves its function.

Athletes also report that vincamine is extremely thermogenic. It causes rapid losses in bodyfat, and it accomplishes this by stimulating the release of the hormone norepinephine. It is, not surprisingly, a popular ingredient in over-the-counter weight loss supplements.

Who needs it and what are some symptoms of deficiency?

Vincamine supplementation can prove incredibly efficacious for elderly persons who are experiencing a decline in cognitive function, and athletes and bodybuilders who need to be lean and focused for competition.

Persons suffering from depression may benefit from vincamine supplementation although, as noted above, its ability to be an effective treatment for depression is situationally dependant. Persons with depression should consult their physician prior to making health treatment choices or changing their behavior.

Persons suffering from vertigo and Alzheimer's may also find vincamine supplementation to be of benefit. Again, these persons should consult their physician prior to making health treatment choices or changing their behavior.

No physiological requirement exists, and there are no symptoms of deficiency.

How much should be taken? Are there any side effects?

Strictly adhere to label dosing guidelines.

Vincamine administration is most effective when the product is taken with food.14

Side-effects are rare, and clinical research has demonstrated that few adverse side-effects were noted at the dosages used during study.15,16

Side-effects are reported only at very high doses and can include blood thinning.17

Although research has shown that vincamine does not interact with blood medications18, persons with blood or blood-related disorders should consult their physician prior to vincamine supplementation.
