Supplement
Ginsenosides
SaveA class of triterpene saponins found in Panax ginseng responsible for most of its adaptogenic, cognitive, and anti-fatigue effects.
Quick verdict
Solid evidence for anti-fatigue and modest cognitive benefits from standardized ginseng extracts; individual ginsenosides vary in effect.
Evidence score
A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.
What the research shows
Systematic reviews support ginseng for reducing fatigue and modestly improving cognitive performance. Ginsenosides modulate the HPA axis, nitric oxide pathways, and inflammatory signaling. Effects depend on the ratio of protopanaxadiol to protopanaxatriol ginsenosides.
Benefits
- Reduces mental and physical fatigue
- Modest improvement in cognitive performance
- May support immune function during stress
- Anti-inflammatory and antioxidant activity
Dosage notes
Standardized extracts typically provide 200-400 mg daily with 4-7% ginsenosides. Cycling (8 weeks on, 2 weeks off) is commonly recommended.
Side effects
- Insomnia
- Headache
- GI upset
- Elevated blood pressure in sensitive individuals
Who should be cautious
May interact with warfarin, diabetes drugs, and MAOIs. Stimulatory effects can worsen insomnia or anxiety in sensitive individuals.
