Shilajit is a mineral-rich resin that seeps from rocks in high mountain ranges, formed over centuries from decomposed plant matter. Used in Ayurveda for thousands of years as a rasayana (rejuvenator), modern research has identified fulvic acid and dibenzo-alpha-pyrones as its key active compounds. Shilajit is gaining explosive popularity in the West for energy, testosterone, and cognitive support.

What Is Shilajit?
Shilajit (meaning 'conqueror of mountains' in Sanskrit) is a sticky, tar-like substance found primarily in the Himalayan, Altai, and Caucasus mountains at altitudes of 10,000-16,000 feet. It forms over centuries from the slow decomposition of plants by microorganisms.
The resulting resin contains over 80 minerals in ionic form, fulvic acid, humic acid, and other bioactive compounds. Quality varies enormously based on source, purification method, and processing.
- Fulvic acid: Primary active compound (40-60% in quality shilajit)
- Dibenzo-alpha-pyrones (DBP): Unique bioactive compounds
- Minerals: 80+ minerals in bioavailable ionic form
- Humic acid: Supports mineral transport and absorption
- PrimaVie: Most-studied patented, standardized shilajit extract
Energy & Mitochondrial Function
Shilajit's most researched benefit is energy enhancement through mitochondrial support.
- ATP production: Enhances mitochondrial energy production
- CoQ10 synergy: Protects CoQ10 from oxidation, enhancing its effects
- Oxygen utilization: Improves cellular oxygen uptake
- Fatigue: Reduces chronic fatigue in clinical studies
- Exercise: May improve exercise performance and recovery
Testosterone & Male Health
Clinical studies with PrimaVie shilajit show testosterone benefits.
- Free testosterone: 20-30% increase in healthy men after 90 days
- Sperm quality: Improves sperm count, motility, and morphology
- DHEA: May increase DHEA-S levels
- Mechanism: May enhance testicular function and reduce oxidative stress
- Best candidates: Men with low-normal testosterone levels
Cognitive Function & Brain Health
Shilajit shows neuroprotective and cognitive-enhancing properties.
- Alzheimer's: Fulvic acid prevents tau protein aggregation (in vitro)
- Memory: Improves learning and memory in animal studies
- Cognitive decline: May slow age-related cognitive decline
- Brain inflammation: Reduces neuroinflammatory markers
- Gut-brain axis: Fulvic acid may modulate gut microbiome
Altitude Sickness & Adaptogen
Shilajit has traditional use for high-altitude adaptation.
- Hypoxia: Helps cells function better in low-oxygen environments
- Altitude sickness: Reduces symptoms (headache, fatigue, nausea)
- Traditional use: Sherpas and Himalayan populations use shilajit for altitude
- Hematocrit: May help regulate red blood cell production at altitude
- Combination: Often used with rhodiola and cordyceps for altitude
Quality, Purification & Safety
Quality is paramount with shilajit due to contamination risks.
- Heavy metals: Raw shilajit can contain lead, arsenic, mercury
- Purification: Only buy properly purified shilajit (standardized extracts)
- PrimaVie: Patented, GRAS-status, heavy metal tested
- Resin vs powder: Resin is traditional but harder to dose; powder is standardized
- Third-party testing: Always verify heavy metal testing results
Dosage & How to Take Shilajit
Dosage depends on form and standardization.
- PrimaVie (standardized): 250mg twice daily
- Resin: 300-500mg pea-sized portion, dissolved in warm water/milk
- Powder: 300-600mg daily
- Cycling: 3 months on, 1 month off (traditional recommendation)
- Take with warm water or milk on empty stomach
- Take in morning: Energy-enhancing effects may interfere with sleep
Safety & Considerations
Purified shilajit is safe, but raw/unpurified forms carry risks.
- Heavy metals: ONLY use purified, tested shilajit
- Sickle cell: Avoid in sickle cell anemia (case reports of crisis)
- Iron overload: May increase iron absorption (caution in hemochromatosis)
- Gout: May increase uric acid levels
- Pregnancy: No safety data, avoid

Frequently Asked Questions
Is shilajit safe from heavy metal contamination?
Only properly purified and tested shilajit is safe. Raw shilajit from unknown sources can contain dangerous levels of lead, arsenic, and mercury. Always choose branded, standardized extracts like PrimaVie that provide third-party heavy metal testing results.
How long does shilajit take to work for testosterone?
Clinical studies using PrimaVie (250mg twice daily) showed significant testosterone increases after 90 days of consistent use. Some users report energy benefits within 1-2 weeks, but hormonal changes require longer-term supplementation.
Can women take shilajit?
Yes, women can take shilajit. While testosterone studies focus on men, the energy, cognitive, and mineral benefits apply to both sexes. Women may also benefit from shilajit's iron content and mitochondrial support. Avoid during pregnancy and breastfeeding due to lack of safety data.
