Periwinkle

Bio-Activity Analysis
Cerebral Blood Flow Increase (Vincamine vs Placebo)
SCIENTIFIC DATA VISUALIZATION
Health Benefits & Sources
Why You Need It
- Enhanced Cognitive Function: Vincamine helps dilate blood vessels, improving blood flow to the brain which can support memory and mental clarity.
- Neuroprotection: It acts as an antioxidant, helping protect brain cells from oxidative stress.
- Energy Metabolism: It supports mitochondrial function (the powerhouse of cells), potentially reducing fatigue.
Deep Dive
Periwinkle works primarily by inhibiting an enzyme called PDE (phosphodiesterase). When PDE is inhibited, blood vessels relax and widen (vasodilation). This increased blood flow is crucial for high-energy demand organs like the brain. Unlike stimulants that force energy out of nowhere, Periwinkle simply optimizes the delivery system of your existing resources. It is widely studied for age-related cognitive decline but is also used by healthy adults for focus.
Natural Food Sources
It is important to note that Periwinkle (Vincamine) is not found in standard fruits or vegetables. It is an alkaloid derived exclusively from the Vinca plant family. You cannot "eat" Periwinkle from the grocery store produce aisle.
| Food Source | Amount | % DV (Vincamine) |
|---|---|---|
| Vinca Minor Extract | Variable | ~90% (Standardized) |
| Vinca Major | Variable | ~75% |
| Synthetic Vincamine | Variable | 99% |
Supplementation
Because it is not found in food, it is almost exclusively taken as a standardized extract.
- Common Dosage: 15mg to 30mg of Vincamine daily (or 100-200mg of dried herb).
- Who should take it: Adults looking to support memory, seniors experiencing mild cognitive slowing, or those looking for circulatory support.
- Form: Usually found in capsules or combined with other nootropics (brain boosters).
