Panax Ginseng
Also known as: Asian ginseng, Korean ginseng, Ginsenosides, Red ginseng
Ginsenosides (Rg1, Rb1 and others) are the main actives, with partly opposing effects. RCTs show small benefits for fatigue and some cognitive measures, but heterogeneity in extracts and study quality limits firm conclusions.

Overview
Panax ginseng root, standardised for ginsenosides, is a classic adaptogen used for fatigue, vitality and cognitive support. Human trials show modest, inconsistent benefits for fatigue and cognition; quality and ginsenoside content vary widely between products.
Mechanism & Function
Mechanism of Action
Ginsenosides modulate HPA-axis activity, nitric-oxide synthesis and neurotransmitter systems (preclinical). Adaptogenic effects are attributed to normalising stress responses rather than a single target.
Physiological Role
No physiological role; an adaptogenic botanical.
Primary Pathways
Performance / Health Relevance
Studied for fatigue and reaction time; acute ergogenic effects are not established.

Dimensions marked N/A have no indexed evidence of that class. They are shown as unavailable rather than scored.
Practical Use & Dosage
- Minimum Effective Dose
- 200 mg/day of standardised extract
- Optimal Range
- 200–400 mg/day (4–7% ginsenosides)
- Upper / Caution Level
- Insomnia and agitation at high doses
- Timing
- Morning (may disturb sleep if taken late)
- Best Format
- Root extract standardised for ginsenosides
- Bioavailability
- Ginsenosides have low oral bioavailability and are partly metabolised by gut microbiota.
- Absorption Considerations
- Cycled use (e.g. 2–3 weeks on, 1–2 off) is traditional, though not evidence-mandated.
