Vinpocetine
Periwinkle-derived compound that increases cerebral blood flow and glucose utilization in the brain — used in Europe for decades.
What the evidence says
Vinpocetine appears to help in 6 of 6 studies with measurable effects — the evidence leans clearly favourable.
Most evidence is from high-quality meta-analyses and randomised trials published 2003–2026 with a typical study size of 40 participants.

HighWhat the studies found
By outcome
Vinpocetine has an evidence score of 7.5/10 — strong evidence based on 30 indexed studies, including 4 meta-analyses. Periwinkle-derived compound that increases cerebral blood flow and glucose utilization in the brain — used in Europe for decades.
The commonly studied dose of Vinpocetine is 10-30mg daily in divided doses. Research points to an estimated optimal dose around 30mg, with a minimum effective dose near 10mg. Individual response varies — start low and adjust.
The best time to take Vinpocetine is with meals. Take it with food. Vinpocetine is a semi-synthetic derivative of vincamine (from Vinca minor/periwinkle) that enhances cerebral blood flow by inhibiting PDE1 and modulating sodium and calcium channels.

Vinpocetine is a semi-synthetic derivative of vincamine, an alkaloid from the periwinkle plant (Vinca minor). It's been used in Europe for decades to treat cerebrovascular disorders and cognitive impairment. It works primarily by increasing cerebral blood flow, enhancing glucose and oxygen utilization in the brain, and providing neuroprotection. It also has anti-inflammatory and phosphodiesterase-inhibiting properties.

10-30mg daily in divided doses
Loading: Not required
Take with food
| Form | Type |
|---|---|
| 💊Vinpocetine capsules or tablets | Recommended |
Standard vinpocetine is well-absorbed with food. Usually sold in 5-10mg capsules.
Minimum: 4 weeks
Optimal: 12 weeks
Cycling: 8-12 weeks on, 2-4 weeks off
Note: Fat-soluble; absorption improved with food. Take earlier in day to avoid sleep interference.
Based on stroke recovery and dementia studies. CAVIN trial (n=469) showed significant cognitive improvements. Meta-analysis found modest effect size (0.439 SMD). Limited data in healthy populations. Most evidence from clinical populations with cerebrovascular issues.
Enhanced short-term and working memory
Improved concentration and mental clarity
Better brain circulation
Possible nausea or stomach discomfort
May provide cerebrovascular benefits; consult doctor
May enhance anticoagulant effects
Additive blood-thinning effects
Tip: Start with lower dose
Tip: Take with food
Tip: Usually transient
Vinpocetine is generally safe at recommended doses, with a few precautions worth noting. The most commonly reported side effects are headache, GI upset, flushing. Use caution if any of these apply to you: Bleeding disorders; Upcoming surgery (stop 2 weeks before).
Piracetam
Likely helpsFirst-ever nootropic (1972) that improves membrane fluidity and AMPA receptor function — decades of safety data for cognitive enhancement.
