Panax Ginseng
Also known as Asian ginseng, Korean ginseng, Panax ginseng, Red ginseng
Panax ginseng (Asian or Korean ginseng) is one of the most studied adaptogens, used to support energy, resilience to stress, immune function, and mental performance. Its active compounds, ginsenosides, are thought to drive these effects. Evidence is strongest for reducing fatigue and supporting cognition, with more modest support for immune and metabolic effects.
Benefits
Reduces fatigue and boosts energy
ModerateStandardized extracts have reduced mental and physical fatigue, including in people with chronic illness, across several trials.
Supports cognition and mood
ModerateMay improve aspects of mental performance, working memory, and calmness, particularly under fatigue or stress.
May support immune function
PreliminarySome trials suggest ginseng may modestly reduce the frequency or duration of colds.
Pros & cons
Pros
- Among the most researched adaptogens
- Good evidence for reducing fatigue
- May support cognition under stress
- Long history of traditional use
Cons
- Can be overstimulating and disturb sleep
- Notable interactions with several medications
- Standardization varies between products
Side effects
Overstimulation and insomnia
Can cause restlessness, headache, or trouble sleeping if taken late in the day or at high doses.
Blood sugar and blood pressure changes
May lower blood sugar and affect blood pressure, which matters for people on related medications.
How to take it
Typical dose
200–400 mg of a standardized extract (around 4% ginsenosides) per day
Timing
In the morning with or without food; avoid late-day dosing because it can disturb sleep
Common forms
Tip: Look for products standardized to ginsenoside content. Ginseng is often cycled rather than taken continuously. This is Panax ginseng, which differs from American ginseng (Panax quinquefolius).
