Nootropics Depot - Polygala Tenuifolia 20:1 Extract Powder, Yuan Zhi - 60g

Polygala tenuifolia, known as Yuan Zhi in traditional Chinese medicine, is unusual in being both calming and stimulating at once. This 20:1 concentrated root extract supports focus and mental clarity while promoting stress resilience, producing the calm-focus state that normally requires careful stacking of several compounds.

Nootropics Depot uses a dual water and ethanol extraction to capture the full spectrum of bioactive compounds: water-soluble tenuifolin alongside alcohol-soluble polygalasaponins and oligosaccharide esters. The 20:1 ratio means 20 grams of raw root produces one gram of finished extract. Polygala supports healthy BDNF and nerve growth factor levels, both central to neuroplasticity and memory formation, and modulates acetylcholine activity involved in attention and learning.

Take 100mg one to three times daily, with or without food, at any time of day. Effects are typically immediate but subtle rather than stimulant-like. No scoop is included, so a milligram scale is required.
