Vinpocetine is a chemical substance synthesized from vincamine, a natural constituent found
in the leaves of Vinca minor (lesser periwinkle).
Where is it found?
Vinpocetine is synthesized 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):
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. 1

Are there any side effects or interactions?
Studies on vinpocetine report no serious side effects with amounts up to 60 mg per day.
2 Vinpocetine has blood-thinning effects, 3 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. 4
Are there any drug
Certain medicines may interact with vinpocetine. Refer to drug interactions for a list of those medicines.
