Eleuthero
Also known as: Siberian Ginseng, Eleutherococcus senticosus, Eleuthero Root, Ciwujia
Effective Dosage
No established dose (insufficient research data)
What the Science Says
Eleuthero is a root extract from a shrub native to Northeast Asia, traditionally used as an adaptogen — a substance believed to help the body handle stress. The provided research does not include any clinical trials testing eleuthero on its own; it appeared only as one ingredient in a multi-ingredient fat-loss supplement blend. One lab study found that Siberian Eleuthero inhibited the drug-metabolizing enzyme CYP3A4, which could affect how other medications are processed in the body. No standalone dose or timeframe for human benefit can be established from the available data.
What It Doesn't Do
No proof it reduces stress or fatigue on its own — all human data comes from blends with caffeine and other stimulants. No evidence from these studies it boosts immunity, improves athletic performance, or acts as a standalone adaptogen. Don't assume it's safe to combine with prescription drugs — it may interfere with how your body processes medications.
Evidence-Based Benefits
Eleuthero is considered an adaptogen, which means it may help the body adapt to stress and enhance overall resilience. Some limited studies suggest it may improve physical performance and reduce fatigue, but the evidence is not robust.

Absorption & Bioavailability
Unknown — no pharmacokinetic data for eleuthero was provided in the available studies
Red Flags to Watch For
- Eleuthero inhibited CYP3A4 (a key drug-metabolizing enzyme) more potently than a low dose of ketoconazole in lab testing — this raises real drug interaction concerns for anyone on prescription medications
- All human study data comes from a multi-ingredient product containing caffeine, yohimbine, and other stimulants — any observed effects cannot be attributed to eleuthero alone
- Widely sold in over 1,000 registered supplement products despite a near-total absence of standalone clinical trial evidence
- Often marketed as 'Siberian Ginseng' — it is not true ginseng and the two should not be assumed equivalent in effect
