Scientific Research Shilajit
Clinically Studied. Not Traditionally Assumed.
Shilajit, validated beyond tradition. Backed by 10+ years of human clinical research across 500+ participants with measurable outcomes.
From hormone support to strength and recovery, every claim is clinically observed, not assumed. Not just felt. Proven in data..
Clinically studied outcomes. Backed by human trials.
Shilajit has been evaluated across multiple controlled human studies-demonstrating measurable improvements in hormonal health, physical performance, and overall vitality.
Each outcome is supported by defined dosages, durations, and clinically observed results, not assumptions.
Our research findings
Supports Healthy Testosterone Levels
Shilajit supplementation 250 mg twice daily for 90 days increased total testosterone by ~20–23% in healthy men aged 45–55.
- Randomized, double-blind, placebo-controlled trial
- Also increased free testosterone and DHEAS
Why It’s Important
Supports energy, drive, and overall male vitality as testosterone naturally declines with age.
Helps Maintain Strength Under Fatigue
Shilajit supplementation ~500 mg/day for 8 weeks reduced strength decline under fatigue by ~8 12% in active men.
- Controlled human study
- Improved muscle performance during repeated exertion
Why It’s Important
Helps sustain performance and reduce burnout during physically demanding routines.
Improves Strength & Endurance
Supplementation 500 mg/day for 28 days improved strength output by ~10–15% in healthy adult men.
- Human pilot study
- Also showed improvements in endurance and fatigue markers
Why It’s Important
Supports day-to-day strength, stamina, and physical resilience.
Supports Female Sexual Function
Shilajit supplementation 200 mg twice daily for 60 days increased FSFI scores by ~25% (23.1 → 28.9) in sexually active women-moving from dysfunction to normal range.
- Triple-blind, randomized, placebo-controlled trial
- Clinically validated sexual function score
Why It’s Important
Supports improvements in sexual function that may contribute to better emotional comfort, mood, and relationship stability.
What powers our research
Our research is driven by clinically studied Shilajit standardized for active compounds like fulvic acid. We rely on controlled human trials to understand its impact on strength, hormones, and performance. Each claim is backed by measurable outcomes-not assumptions or traditional use alone. This ensures what you experience is rooted in science, not speculation.
Understanding the clinical research behind Shilajit
We base our claims on controlled human studies evaluating purified Shilajit resin. Each trial is designed to measure real physiological outcomes like testosterone, strength, and fatigue response.
Our approach focuses on clinically relevant doses, defined durations, and measurable endpoints. This ensures every claim reflects observed results-not assumptions or traditional claims alone.
How the research was evaluated

What the research shows
Clinical studies show Shilajit supports measurable improvements in testosterone, strength, endurance, and fatigue response.
Across controlled human trials, participants demonstrated consistent gains compared to placebo. Key outcomes include ~20–23% increases in testosterone and ~10–15% improvements in strength output.
These results reflect real physiological changes-not just perceived benefits.
How we apply these findings
We translate clinical results into standardized dosing and formulation to ensure consistent, real-world effectiveness.
Every batch is aligned with studied parameters so what’s proven in research is what you actually experience.

FAQs
What Is Shilajit And Why Has It Been Studied In Human Trials?
Shilajit is a naturally occurring mineral resin that has been traditionally used for vitality and wellness. Over the past decade, researchers have evaluated purified Shilajit in controlled human studies to better understand its effects on strength, recovery, hormone health, endurance, and overall vitality.
What Health Areas Have Been Studied In Human Research?
Human studies have investigated Shilajit across several areas including:
• Testosterone and hormone support
• Strength and physical performance
• Endurance and fatigue resistance
• Recovery from physical exertion
• Female sexual function and vitality
Research continues to explore how Shilajit may support overall wellness and healthy aging.
Does Research Show That Shilajit Supports Healthy Testosterone Levels?
Yes.
Controlled human studies have reported improvements in testosterone-related markers in healthy men following consistent Shilajit supplementation.
Research has also reported increases in free testosterone and DHEAS in certain study populations.
What Does The Research Say About Strength And Physical Performance?
Human studies have observed improvements in strength output, endurance, and physical performance following daily supplementation with purified Shilajit.
Researchers have also reported improvements in fatigue-related performance markers during repeated physical exertion.
Does Research Suggest Shilajit Helps With Fatigue And Recovery?
Research indicates that Shilajit may help maintain physical performance under fatigue and support recovery following demanding activity.
These findings have been observed in controlled human studies using defined dosages and study durations.
Has Shilajit Been Studied In Women?
Yes.
Human clinical research has evaluated purified Shilajit in women and reported improvements in validated measures of female sexual function following consistent supplementation.
These studies were conducted using randomized, placebo-controlled designs.
How Were The Studies Evaluated?
The research featured on this page is based on controlled human studies that measured specific physiological outcomes.
Researchers evaluated defined endpoints such as testosterone levels, strength output, fatigue response, endurance markers, and validated health assessment scores.
Why Do Different Studies Use Different Dosages And Durations?
Clinical studies are designed to evaluate specific outcomes.
As a result, dosage amounts and study durations may vary depending on whether researchers are investigating hormone health, strength, endurance, recovery, or other physiological markers.
Does Research Guarantee The Same Results For Everyone?
No.
Clinical studies help identify average outcomes observed within a study population.
Individual results may vary based on age, lifestyle, nutrition, activity levels, health status, and consistency of use.
Why Does Naturesactiv Focus On Human Research Instead Of Traditional Claims Alone?
Traditional use provides historical context, but human clinical research helps measure real physiological outcomes under controlled conditions.
Our approach is to rely on clinically observed data whenever possible so that claims are supported by measurable evidence rather than tradition alone.
