What is it?
Vinpocetine is a chemical substance synthesised from vincamine, a natural constituent found in the leaves of Vinca minor (lesser periwinkle).
Vinpocetine appears to have antioxidant,1 blood flow enhancing,2 3 4 5 and other effects that may be beneficial to brain function. 6 7 8 9 10 Research, primarily in Europe, has investigated these possible benefits in people with memory disorders (dementias) and people who have suffered strokes.
Where is it found?
Vinpocetine is synthesised from vincamine, a constituent of the leaves of Vinca minor (lesser periwinkle)
Vinpocetine has been used in connection with the following condition (refer to the individual health concern for complete information):
| Rating | Health Concerns |
|---|---|
 |
|
 |
Stroke (intravenous vinpocetine only) |
 |
Memory Urinary incontinence |
|
Reliable and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary
studies suggesting a health benefit or minimal health benefit. For an herb, supported by traditional use but
minimal or no scientific evidence. For a supplement, little scientific support and/or minimal
health benefit. | |
Who is likely to be deficient?
Vinpocetine is not an essential nutrient, so no deficiencies are possible.
How much is usually taken?
Research has typically used 30 to 60 mg per day of vinpocetine. Taking vinpocetine with food appears to dramatically improve its absorption. 11
Are there any side effects or interactions?
Studies on vinpocetine report no serious side effects with amounts up to 60 mg per day. 12 Vinpocetine has blood-thinning effects, 13 which suggests that people with bleeding disorders or who are taking anticoagulant or other blood-thinning medications should consult a doctor before taking vinpocetine. However, one study found no such interaction between vinpocetine and the anticoagulant drug warfarin. 14
Are there any drug
interactions?
Certain medicines may interact with vinpocetine. Refer to drug interactions for a list of those medicines.
