In the United States, it is commonly sold as a dietary supplement for the general population either alone or with other ingredients. Its numerous proposed uses include for improvement of brain function, rapid weight/fat loss, increases in energy, enhancement in focus and visual acuity, prevention of motion sickness, hearing and eye disorders, chronic fatigue syndrome and treatment of menopausal symptoms.
Vinpocetine was compared with Ifenprodil tartrate (known for its cerebral vasodilator effect), DHEM (Dihydroergotoxine mesylate), Xantinol nicotinate (known for its vasodilatory effect in the ear), and Lucidril (also a vasodilator). A study attempting to identify the best dose for vinpocetine is also presented in this section.
Some of these purposes make it a product for athletes too. (Chemical Information Review Document for Vinpocetine, National Toxicology Program, U.S. Department of Health and Human Services, Research Triangle Park, NC, 2013).
As compared with placebo, Vinpocetine was found to be capable of reducing hypoxia through oxygenation in healthy men that were submitted to induced hypoxia with a lower than normal concentration of oxygen (10.5 %). The volunteers reported better subjective well-being in the treated vs. Placebo group. Vinpocetine was also capable of improving memory retention time processes in middle-aged (25-40) healthy women. This result was confirmed by another study on a different group of women of similar age. In patients with a low level of vestibular stability, vinpocetine was shown to be able to prevent antimotion.
