HighWhat the studies found
By outcome
Panax Ginseng has an evidence score of 9/10 — very strong evidence based on 53 indexed studies, including 8 meta-analyses. Ginsenosides combat fatigue, sharpen cognitive function, and enhance stress resilience — distinct from American and Siberian ginseng.
The commonly studied dose of Panax Ginseng is 200-400mg standardized extract. Research points to an estimated optimal dose around 400mg, with a minimum effective dose near 200mg. Individual response varies — start low and adjust.
The best time to take Panax Ginseng is in the morning. Taking it with food is preferred. Panax ginseng contains ginsenosides that modulate the HPA axis, nitric oxide synthesis, and GABA/glutamate signaling.
