For centuries, Shilajit has been revered in Ayurvedic medicine. Called a “destroyer of weakness” and a rejuvenating tonic, the substance is drawn from the high-altitude rocks of the Himalayas. Despite centuries of Ayurvedic use, modern users want to know about Shilajit studies. What does the science say?
Shilajit is a dark, resinous mineral complex. Scientists are studying the unique concentration of compounds. These include Fulvic Acid, trace minerals, and bioactive compounds. Researchers want to know how it may support vitality, energy metabolism, and cellular protection. There are a growing number of studies aiming to bridge the gap between tradition and evidence.
Today, we’re outlining the latest Shilajit clinical studies, human trials, and scientific findings. These can shed light on how this ancient, natural resin interacts with the body. Purity and sourcing, you’ll see, are also key to supporting your health.
What Is Shilajit and Why Is It Being Studied?
Shilajit looks a bit like a sticky, black, or brown tar-like substance. It is a natural mineral exudate that seeps from layers of rock in mountain regions like the Himalayas and the Altai.
It forms over centuries as organic plant material and microbes decompose under geological pressure. This produces a dense resin rich in Fulvic Acid and humic substances, and more than 80 trace minerals. These compounds are believed to offer health benefits. Among them, nutrient absorption, support for mitochondrial function, and antioxidant action.
Shilajit research focuses largely on the Fulvic Acid. This key component acts as a natural chelator, binding to minerals and improving their cellular uptake. This mechanism has inspired studies into Shilajit’s potential roles in several fields:
- Energy production and mitochondrial support
- Testosterone and reproductive health
- Cognitive performance and neuroprotection
- Adaptogenic resilience and stress response
- Anti-aging and cellular protection
- Muscle recovery and exercise adaptation
- Immune system support
- Antioxidant activity and oxidative stress mitigation
- To verify Ayurvedic historical use as a rasayana for vitality in high-altitude populations
Now, modern labs are testing those same properties using controlled models and clinical trials. Some studies are demonstrating the substance holds up to its ancient reputation.

Key Scientific Studies on Shilajit’s Benefits
Below are summaries of key clinical trials and studies on Shilajit and its components.
Shilajit and Testosterone Support
The first study on our chart and citation list above is one of the most citedShilajit clinical studies. (Published (2016 in Andrologia). This study involved 75 healthy men aged 45–55. Though a small assay, the study is very promising in terms of male reproductive health and vitality.
Dose amount: 250 mg
Dose frequency: Twice daily
Duration: 90 days
Compared to placebo: Total and free testosterone increased
Researchers attribute these outcomes to Shilajit’s Fulvic Acid and dibenzo-α-pyrones. These compounds may support energy production in the testes and promote hormone synthesis. The results are promising, but more long-term, placebo-controlled human trials are needed.
Scientists are also looking to prove support for sperm mobility, hormone balance, and endocrine safety.
Shilajit and Brain Health
A 2012 study from our timeline (International Journal of Alzheimer’s Disease) tested Shilajit’s Fulvic Acid. It reduced tau protein aggregation, a key factor in Alzheimer’s disease. This suggests potential neuroprotective effects.
A 2022 review from our timeline found that Fulvic Acid’s antioxidant and metal-binding activity may boost energy in brain cells. This could help cognitive endurance and points to potential anti-aging benefits.
Shilajit for Energy and Fatigue Reduction
Mitochondrial support is one of the best-documented areas of Shilajit benefits science.
A 2012 study from our timeline (Journal of Ethnopharmacology) tested Shilajit in rats. It improved mitochondrial function and energy production.
Later reviews (2020–2023) applied these findings to humans. They found higher ATP output and lower oxidative stress in people taking purified Shilajit.
Researchers think Fulvic Acid helps by supporting electron transport and nutrient absorption.
Shilajit and Iron Deficiency or Anemia
Animal studies dating back to 2010 offer interesting promise for iron absorption, a key metric of human health. Shilajit human trials revved up in 2022 to discover its effects on anemia.
It’s thought that Shilajit’s trace minerals and Fulvic Acid may enhance iron absorption in mildly anemic adults. This mechanism is biologically plausible, but remains to be wholly proven.
Shilajit’s Role in Heart and Muscle Health
Cardiovascular and muscle recovery research suggests Shilajit may act as a performance-enhancing adaptogen. A 2016 double-blind trial published in the Journal of Medicinal Food shed some light.
Dose amount: 500 mg
Dose frequency: Once daily
Duration: 8 weeks
Compared to placebo: Improved exercise adaptation and reduced fatigue
In animal models, Shilajit’s antioxidant compounds appeared to protect cardiac tissue. (Particularly against hypoxia-induced injury.) Together, these findings support Shilajit’s potential to enhance endurance and heart resilience. As in other fields of study, more research is needed for clinical validation.
Fulvic Acid: The Bioactive Backbone of Shilajit
Fulvic Acid Shilajit research shows that it is a major component of Shilajit. Fulvic Acid makes up about 15% to 20% of its weight, but this can be more with extracts. Fulvic Acid helps carry negatively charged ions. This binds nutrients and moves them into cells in a process called nutrient chaperoning.
Studies on Fulvic Acid show it acts as a strong antioxidant. It may reduce inflammation and help remove toxins. These effects may support health at the cellular level.
FDA Warning on Fulvic Acid Sourcing
Shilajit is not approved by the FDA as a treatment for any disease or condition. Neither is Fulvic Acid. (This is common with botanical supplements.) In fact, due to contamination concerns, the FDA has issued warnings about products containing Fulvic Acid. This is why quality, purity, and sourcing are so imperative.
If you want to get the full wellness impact, you’ll have to be selective when you purchase Shilajit for consumption. Fulvic Acid and Shilajit quality both vary in concentration and purity by source.

Safety and Dosage in Scientific Context
According to recent Shilajit safety studies, purified Shilajit appears safe.
Studies show Shilajit can stress the liver and kidneys if used for a long time. Human safety data for prolonged use are limited. Though most research doesn’t produce notable toxicity, one study in rats suggests shorter-term use is best.
A 2012 study systematically tested black Shilajit administered daily to rats.
Dose amount: 500 mg/kg, 2,500 mg/kg, and 5,000 mg/kg body weight
Dose frequency: Once daily
Duration: 91 days
Results were compared to a control group receiving only vehicle (no Shilajit). No significant toxicity or adverse changes were observed in treated groups compared to the control, except some negligible changes in the liver and intestine at the highest dose. These were not significant enough to indicate harmful long-term effects, but extended study in humans is needed.
