Ginseng
Also known as: Panax ginseng, Korean red ginseng, ginsenosides, ginseng berry, Asian ginseng
Effective Dosage
200-1000 mg daily based on study doses
What the Science Says
Ginseng is a root herb used for centuries in traditional medicine, now studied for its active compounds called ginsenosides and polysaccharides. Clinical trials show it can meaningfully reduce fatigue — including in cancer survivors — and may help regulate blood sugar when taken before meals. Reviews of sports nutrition research suggest doses of 200–400 mg daily may support endurance, reduce muscle damage markers, and speed recovery, though individual responses vary.
What It Doesn't Do
Won't cure cancer or replace cancer treatment. No clinical evidence it directly builds muscle. Not a proven testosterone booster based on the provided data. Don't expect overnight results — most trials ran 4–12 weeks. Preclinical findings on spinal cord injury and cognitive aging are animal studies only and cannot be applied to humans yet.
Evidence-Based Benefits
Ginseng is known for its potential to enhance energy levels, reduce fatigue, and improve cognitive function. It may also support immune function and help the body adapt to stress, thanks to its adaptogenic properties.

Absorption & Bioavailability
Unknown from provided studies — absorption of ginsenosides is not directly measured in the clinical trials provided. Timing of intake appears to matter for blood sugar effects, suggesting bioavailability may be dose-timing dependent.
Red Flags to Watch For
- May interact with anticoagulant medications (e.g., warfarin) — flagged in sports nutrition review
- Many products on the market are poorly standardized; ginsenoside content varies widely between brands
- Most mechanistic evidence (neuroprotection, reproductive protection, cognitive aging) comes from animal or cell studies — not proven in humans
- Ginseng berry and ginseng root are different preparations with different compound profiles; labels may not distinguish them
- Short study durations (4–12 weeks) mean long-term safety data is limited
