How it works
Modulates stress pathways and supports energy production, improving cognitive performance.
Overview
Panax Ginseng is one of the most established adaptogens, with evidence supporting both cognitive and physical performance benefits. It works by helping the body adapt to stress while also supporting sustained energy levels. Effects can vary depending on extract quality and dosage, but it is generally effective for improving mental clarity and reducing fatigue.
The evidence
Panax ginseng is a traditional adaptogen with some evidence for acute mental performance — single doses have improved attention and working memory in healthy volunteers in small trials. For sustained cognitive enhancement the picture is weaker: a Cochrane review concluded there was no convincing evidence of a lasting effect in healthy people, while trials in cognitive impairment are more encouraging but lower quality.
How to dose it
Commonly studied at 200–400 mg/day of a standardised root extract. Acute-effect studies use single doses in a similar range.
When to take it
Both — some acute attention effects are reported, alongside chronic adaptogenic use.
Safety & side effects
Generally well tolerated; it can be mildly stimulating, so late-day doses may disturb sleep, and some report headache or digestive upset.
Who should avoid it
Speak to a clinician if you take warfarin (ginseng may reduce its effect), diabetes medication (it can lower blood sugar), stimulants, or MAOIs. Avoid in pregnancy. Periodic breaks are traditional with adaptogens.
