What Is Shilajit? Benefits, Active Compounds & How to Use It
Shilajit is one of those substances that sounds almost too exotic to be real — a tar-like resin that seeps from the cracks of high-altitude Himalayan rock, formed over centuries from the compression and decomposition of plant matter. But the research behind it is substantive enough that it's earned a place in my practice as a genuine functional supplement, not just a trending ingredient.
In Ayurvedic medicine, shilajit has been classified as a rasayana — a rejuvenating substance — for over 5,000 years. The Sanskrit name translates as "destroyer of weakness." Modern research has started to validate specific aspects of that traditional reputation, particularly around energy metabolism, testosterone support, and mineral delivery. This article covers what shilajit actually is, what's in it, what the human research shows, and how to use it effectively.
My Take as a Nutritionist: I use shilajit in practice primarily for three things: energy support in people who feel chronically depleted, mineral replenishment in people eating clean but still showing deficiencies, and testosterone and vitality support in men over 40. The key distinction I always make is between purified shilajit — which is what the clinical research uses and what I recommend — and raw resin, which carries real contamination risks. Quality matters enormously with this particular supplement. — Jordan Dorn CN
What Is Shilajit?
Shilajit is a naturally occurring resinous exudate found primarily in the Himalayan mountain range, as well as in the Altai, Caucasus, and other high-altitude regions. It forms over hundreds to thousands of years through the geological compression of plant and microbial matter — essentially ancient organic material that has been slowly transformed by pressure, temperature, and microbial activity into a dense, mineral-rich substance.
It's typically dark brown to black, with a tar-like consistency at room temperature that becomes more fluid with heat. The composition varies somewhat by region and altitude, but high-quality Himalayan shilajit consistently contains a complex matrix of bioactive compounds that make it genuinely unique among supplements.
What's Actually in Shilajit?
Understanding shilajit's benefits requires understanding its composition. This isn't a single-compound supplement — it's a complex of multiple synergistic actives.
Fulvic Acid — The Primary Active
Fulvic acid typically comprises 50–80% of high-quality purified shilajit and is considered its primary bioactive compound. It's a small, highly bioavailable organic acid that acts as a natural chelator — it binds to minerals and nutrients and transports them across cell membranes with significantly greater efficiency than unchelated mineral forms. Fulvic acid also has documented antioxidant properties and supports mitochondrial function. For a deeper comparison of shilajit's fulvic acid content versus a dedicated fulvic acid supplement, see our fulvic acid vs. shilajit guide.
Dibenzo-Alpha-Pyrones (DBPs)
DBPs are a class of compounds largely unique to shilajit and are believed to contribute significantly to its mitochondrial energy support. They appear to protect CoQ10 in its active form and may support the electron transport chain — the cellular machinery responsible for ATP (energy) production. This is one of the mechanisms behind shilajit's documented fatigue-reducing effects.
84+ Trace Minerals
Shilajit is one of the most mineral-dense substances in the natural world, containing over 84 trace minerals in carbon-bonded, bioavailable form. These include iron, zinc, magnesium, copper, manganese, potassium, selenium, and many others that are essential for enzyme function, hormone production, bone health, and cellular metabolism. The fulvic acid carrier significantly enhances the bioavailability of these minerals compared to standard mineral supplements.
Humic Acids and Other Bioactives
Beyond fulvic acid, shilajit contains humic acids (larger organic molecules with their own antioxidant and gut-supportive properties), amino acids, plant-based sterols, and various other bioactive compounds that contribute to its broad-spectrum effects.
What the Research Shows: Key Benefits
Energy and Fatigue Reduction
This is shilajit's most consistently documented benefit in human trials. A 2019 study found that supplementation at 250–500mg daily supported muscle strength and reduced fatigue indicators in physically active adults. The proposed mechanism involves DBPs supporting CoQ10's role in mitochondrial energy production — essentially helping your cells produce ATP more efficiently. This is different from caffeine-style stimulation; it's a more foundational cellular energy support that tends to produce sustained energy without a crash.
Testosterone and Male Hormone Support
The testosterone research on shilajit is among the most cited in the supplement space — and legitimately so. A 90-day placebo-controlled study of men aged 45–55 found that those supplementing with purified shilajit at 250mg twice daily had significantly higher total and free testosterone levels compared to the placebo group at the study's end. A separate study of infertile men found improvements in sperm count, motility, and morphology after 90 days of supplementation. These are meaningful findings in a supplement category that's full of unsupported claims.

Cognitive Function and Brain Health
Fulvic acid has been studied for its potential neuroprotective properties, with research showing it may inhibit the aggregation of tau protein — a hallmark of Alzheimer's disease progression — in laboratory models. More broadly, shilajit's antioxidant properties and mineral content support overall brain health and cognitive clarity. Most of the cognitive research is still preclinical, but the mechanisms are plausible and the traditional use of shilajit as a brain tonic is consistent with emerging findings.
Mineral Replenishment
In an era of nutrient-depleted soil and increasingly processed food, shilajit's 84+ bioavailable trace minerals represent genuine nutritional value. The chelated, carbon-bonded form of these minerals — delivered through fulvic acid — is absorbed more efficiently than the inorganic mineral forms used in most supplements. For people who eat a clean diet but still show low mineral status on bloodwork, shilajit can be a meaningful nutritional support tool.
Antioxidant and Anti-Inflammatory Support
Multiple in vitro and animal studies have documented shilajit's antioxidant activity through several pathways, including free radical scavenging and modulation of inflammatory signaling via NF-κB pathways. Chronic oxidative stress and low-grade inflammation underlie most chronic disease — shilajit's multi-pathway antioxidant activity makes it relevant to long-term wellness support, not just acute supplementation.
Women's Health
While most of the headline research involves men, shilajit has documented benefits for women as well. Its mineral content — particularly bioavailable iron — is relevant for women dealing with iron deficiency. The endocrine system support from fulvic acid and trace minerals can contribute to hormonal balance. The adaptogenic and energy-supporting properties apply regardless of sex. Shilajit is not recommended during pregnancy or breastfeeding due to insufficient safety research in these groups.
How to Use Shilajit
Dosage
The most widely researched dosage range is 250–500mg of purified shilajit daily, which aligns with the human clinical trials showing testosterone and fatigue benefits. Start at the lower end — 250mg — for the first week to assess tolerance, then increase if well-tolerated. For detailed dosing guidance including timing, cycling, and form-specific considerations, see our complete shilajit dosage guide.
Form Matters
Purified liquid or water-soluble extract is the recommended form for most people. It offers the highest bioavailability, has undergone the purification process that removes contaminants, and is easiest to dose precisely. Raw resin is the traditional form and can be potent, but carries significant contamination risks — heavy metals including thallium, lead, and arsenic have been found in raw and poorly processed shilajit products. Always look for third-party tested products with a certificate of analysis confirming both fulvic acid content and heavy metal levels within safe limits.
Timing
Most practitioners recommend taking shilajit in the morning, ideally on an empty stomach or with warm water, to maximize absorption. The fulvic acid carrier enhances uptake regardless of food timing, but morning use aligns well with its energy-supporting effects. If you experience any digestive sensitivity, taking it with a small amount of food reduces irritation.
Cycling
Long-term daily use is common and generally well-tolerated in purified forms. Many practitioners recommend optional cycling — 8–12 weeks on, 2–4 weeks off — to maintain sensitivity to the supplement's effects, though this is precautionary rather than strictly evidence-based.
Quality and Safety
This is the most important section of this article. Shilajit's quality spectrum is enormous — from genuinely therapeutic purified extracts to raw products that carry real contamination risks.
The critical factors to look for: purification process (raw shilajit is not appropriate for regular supplementation), third-party heavy metal testing (get a COA with specific values, not just a "passed" label), fulvic acid standardization (quality products specify the percentage), and sourcing transparency (altitude and region matter for mineral profile).
For a comprehensive breakdown of shilajit's safety profile including specific risk factors, contraindications, and what to avoid, see our shilajit side effects and safety guide.
Specific populations who should avoid shilajit or use only under medical supervision: people with gout (shilajit can raise uric acid levels), those on anticoagulant medications (potential interaction), people with active infections (the iron content can theoretically feed certain pathogens at high doses), and pregnant or breastfeeding women.
