Eleuthero
Eleutherococcus senticosus (Siberian Ginseng)
Adaptogen that supports endurance, stress resilience, and immune function — distinct from true ginseng.
Eleuthero, formerly called Siberian Ginseng, is a hardy adaptogen used extensively in Russia for performance, stress, and immune support. Unlike Panax ginseng, it doesn't contain ginsenosides but has its own active compounds (eleutherosides). Research supports benefits for endurance, fatigue reduction, and immune function. Gentler and less stimulating than Panax ginseng.
Mechanisms of Action
Adaptogenic Effects
Modulates stress response and improves resilience
Immune Modulation
Supports healthy immune function
Recommended Dose
300-1200mg extract (standardized to 0.8% eleutherosides)
Optimal Timing
- Morning
- Before exercise
Take with food
Best Form
Standardized root extract
Alternatives: Dried root, Tincture
Look for standardization to eleutherosides. Root is the traditional part used.
Duration
Minimum: 4 weeks
Optimal: 12 weeks
Cycling: 6-8 weeks on, 2 weeks off. Russian practice was continuous for months.
Note: Take earlier in the day. Can be mildly stimulating.

“For most phytonutrients, the effects of supplementation on HPA-axis activity in humans is unclear.”
Key Findings:
- For most phytonutrients, the effects of supplementation on HPA-axis activity in humans is unclear.
- Before more definitive conclusions about the effects of phytonutrients on the HPA-axis can be made, further research is required.
- Further research warranted to confirm findings

“Still, its conservation and sustainable production are critical and require ongoing research and innovative cultivation strategies.”
Key Findings:
- With increasing demands and conservation concerns, sustainable cultivation practices are essential, as ES is endangered in some areas.
- Plant biotechnology techniques offer solutions to enhance secondary metabolite yields while ensuring genetic stability and minimizing environmental impacts.
- ES is a promising natural resource for various industries because of its extensive benefits.
- Still, its conservation and sustainable production are critical and require ongoing research and innovative cultivation strategies.

Key Findings:
- Three major types of ginseng are described.
- Asian ginseng is more potent than American ginseng; however, most supplements come from American and Asian types of ginseng.
- Purchases should be made from reputable sources owing to the lack of standardization of the production of herbal supplements.Copyright © 2020 Elsevier Inc.

“This paper reviews recent findings on the pharmacological properties of A. senticosus, with a focus on its anticancer effects.”
Key Findings:
- In the past decades, researchers worldwide have conducted systematic investigations on this herb, from chemistry to pharmacology, and a large number of chemical components have been characterized for their significant pharmacological effects.
- However, reports about the anticancer effects of this plant had been rare until recently, when considerable pharmacological experiments both in vitro and in vivo were conducted to study the anticancer effects of this herb.
- A. senticosus has been found to have inhibitory effects on malignant tumors, such as those in the lung and liver, suggesting that A. senticosus has potential to be developed as an effective anticancer drug.
- This paper reviews recent findings on the pharmacological properties of A. senticosus, with a focus on its anticancer effects.

“The multi-ingredient product's potential enhancement of FAO during exercise, satiety, and RPE reduction suggests an acute effectiveness of SHRED in improving the exercise-related fat loss benefits.”
Key Findings:
- FAO increased in SHRED from Pre1 to Pre2 [0.56 ± 0.26 to 0.96 ± 0.37, (p = 0.003, d =1.34)] but not in PL [0.67 ± 0.25 to 0.74 ± 0.19, (p = 0.334) d = 0.49], with no differences were found between conditions (p = 0.12, d = 0.49).
- However, Cohen's d = 0.77 revealed moderate effect size in favor of SHRED from Pre to Post exercise.
- However, a trend was shown towards improved satiety in SHRED compared with PL, [F(1,11) = 3.58, p = 0.085].
