How does NSI® BioVinca® Vinpocetine work?
Vinpocetine is a chemical substance synthesized from vincamine, a natural constituent found in the leaves of the Vinca minor (lesser periwinkle) plant. Popular in Europe and Japan as a memory-enhancing supplement for the past several decades, vinpocetine has recently become available as a dietary supplement in the U.S.

Normal aging may result in reduced blood flow to the brain and a decrease in the metabolic activity of brain cells.

Vinpocetine is believed to promote healthy cognitive function by acting as a cerebral vasodilator, meaning it enhances blood flow to the brain. Vinpocetine works by inhibiting an enzyme called phosphodiesterase type 1 (PDE1), while at the same time reducing intracellular calcium levels. This allows brain blood vessels to relax and increases the amount of blood flowing through them. Vinpocetine also reduces the viscosity or "stickiness" of red blood cells and platelets, allowing blood to flow more freely through narrowed vessels.

In addition, by inhibiting PDE1, which is responsible for breaking down ATP (the primary energy of all cells), vinpocetine is believed to promote a localized increase in energy available to neurons (brain cells). Studies have shown that vinpocetine helps improve short-term memory function and increase critical reaction time in healthy volunteers¹.

BioVinca™ is the only vinpocetine product on the market that's been clinically studied and is manufactured in a pharmaceutical, FDA-approved GMP plant backed by extensive quality control tests.

NSI® BioVinca™ Vinpocetine is better because it:

Is a high-quality supplement, backed by clinical research.

Is available at a greater value than other vinpocetine products on the market.
