Ancient Ayurvedic mineral resin containing fulvic acid and trace minerals, studied for testosterone support, mitochondrial function, and cognitive health
Shilajit is a sticky, tar-like substance that oozes from Himalayan and other mountain rocks, formed over centuries from decomposed plant matter. It's been a cornerstone of Ayurvedic medicine for thousands of years, and modern research is beginning to validate some traditional claims.
The most compelling evidence is for testosterone support in middle-aged men (19% increase in one RCT) and sperm quality improvements. The fulvic acid content may enhance mitochondrial function and nutrient absorption. However, most studies are small, and quality control is a significant concern with many products.
Worth trying for men over 40 seeking natural testosterone support or anyone interested in traditional adaptogens. Quality matters enormously - choose purified extracts from reputable brands with heavy metal testing. Start with 250-500mg daily and assess after 8 weeks.
Science & Mechanisms
What is Shilajit?
Shilajit (also called mumie, moomiyo, or mineral pitch) is a blackish-brown resinous substance found in rocks at high altitudes (1,000-5,000m) in the Himalayas, Altai, Caucasus, and other mountain ranges. It forms over centuries from the slow decomposition of plants by microorganisms.
Key Bioactive Components:
| Component | Concentration | Function |
|---|---|---|
| Fulvic acid | 60-80% | Primary bioactive, antioxidant, nutrient transport |
| Humic acid | 10-20% | Chelation, immune modulation |
| Dibenzo-alpha-pyrones (DBPs) | Variable | Mitochondrial support, energy |
| Trace minerals | 80+ minerals | Zinc, iron, magnesium, selenium, etc. |
| Amino acids | Variable | Protein building blocks |
Mechanisms:
1. Mitochondrial Function:
- Fulvic acid and DBPs support electron transport chain
- May increase CoQ10 levels in tissues
- Enhances ATP production
- Studies show improved exercise capacity and reduced fatigue
2. Testosterone & Reproductive Health:
- Pandit et al. (2016): 250mg twice daily for 90 days increased total testosterone by 19% and free testosterone by 20% in healthy men aged 45-55
- Biswas et al. (2010): Improved sperm count (+61%), motility, and testosterone in infertile men
3. Cognitive Support:
- Fulvic acid may inhibit tau protein aggregation (Alzheimer's mechanism)
- Traditional use for memory and mental clarity
- Carrasco-Gallardo et al. (2012): Reviewed neuroprotective potential
4. Nutrient Absorption:
- Fulvic acid enhances mineral bioavailability
- Acts as a natural chelator
- May improve absorption of other supplements
Traditional Uses (Ayurveda):
- Rasayana (rejuvenator) - considered one of the most powerful
- "Conqueror of mountains and destroyer of weakness"
- Used for weakness, sexual dysfunction, diabetes, cognitive decline
