Vinpocetine Review
What is Vinpocetine?
Vinpocetine is an extract from the periwinkle plant that is used to increase blood flow to the brain. It may also help protect against memory loss, specifically due to aging. For bodybuilding, vinpocetine is used to increase exercise performance. Because studies of vinpocetine are still relatively rare and side effects are largely unknown, it is recommended that initial dosages remain between 2 and 5 mg (Source: http://en.wikipedia.org/wiki/Vinpocetine).
What about Vinpocetine and weight loss?
Exactly. No clinical trials studying vinpocetine and weight loss could be found for mice, rats, guinea pigs, or humans. Any direct effect on weight has not been demonstrated. Effects on exercise enhancement have not been established either. According to Wikipedia:
No studies have been conducted on the effectiveness of vinpocetine on performance enhancement during exercise.
Conclusion
Basically, vinpocetine might help you remember to take your diet pills, but it probably won’t contribute to their effectiveness. And chances are high that a diet pill with a “proprietary blend” won’t contain a high enough dosage to have an effect anyway.
