Reported Uses

Vinpocetine has seen clinical use in the treatment of disorders that involve inadequate blood flow to the brain. For instance, the incidence and risk of stroke may be reduced by vinpocetine, though this effect is debated. (1) Scientists think the reason for this benefit may involve vinpocetine’s potential ability to enhance blood flow to the brain, dilate blood vessels, support the proper function of red blood cells and reduce blood viscosity. (2) , (3) , (4)

As part of its support of healthy brain function, vinpocetine may enhance memory, learning and cognitive performance in patients suffering from dementia. (5) , (6) , (7) This may be partially due to vinpocetine’s potential ability to enhance the production of energy in the brain. Because of this effect, vinpocetine may also function as an anticonvulsant. (8) , (9)
