• Vinpocetine is a supplement used to increase memory function and mental alertness. It may improve certain hearing, sight and cardiovascular functions. Use vinpocetine alone or in conjunction with other supplements for increased benefits. It has been studied extensively and thus far the results show that vinpocetine benefits far outweigh the minute side effects (see link in Resources). Vinpocetine is sold over the counter as a supplement in the United States but is available only by prescription in Europe and other countries.
  
  

Producing Vinpocetine

• Periwinkle or vinca minor grows abundantly in shaded woodlands with little sunlight. This plant produces seeds, which people harvest and then extract vincamine and its derivative vinpocetine. Vinpocetine is effective in increasing memory and other functions, but it is more desirable than vincamine because findings show it does not have the side effects associated with vincamine.
  
  

How Vinpocetine Works

• Vinpocetine works by dilating the blood vessels, thus allowing blood to flow more freely to the brain. This blood flow brings more oxygen to the brain as well as increasing glucose utilization. It also has a positive effect on the production of adenosine triphosphate (ATP) which is the energy molecule at the cellular level (see link in Resources). Vinpocetine is purported to increase long and short term memory and other benefits include protecting visual and hearing functioning. Visual benefits of vinpocetine include improved night vision. Hearing benefits include reducing or relieving ringing in the ear and vertigo.
  
  

Benefits

• Vinpocetine not only benefits those suffering from memory loss or those with blood circulation diseases, but it also benefits those who wish to enhance their brain functions. Athletes, such as distance runners or skiers, can benefit from the increased oxygenation and energy. Anyone wishing to improve his or her memory can take this over-the-counter supplement.
  
  

Effects

• Vinpocetine does not have many adverse side effects. Use precaution when starting a vinpocetine regimen. There have been some reports of dizziness, weakness and dry mouth when taking this supplement. Take low doses to start with and gradually increase the dose to the desired level unless you suffer any adverse effects. It may take time to notice positive effects. Some people have reported effects in as little as a few hours. For the most, however, effects are noticed after implementing the supplement for a few weeks. If you are already taking medication, check with your health care professional before adding vinpocetine to your daily diet.
