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
interactions?
Certain medicines may interact with vinpocetine. Refer to drug interactions for a list of those medicines.
