Shilajit
The ancient Himalayan mineral resin with modern clinical evidence for testosterone and energy
Also known as: Mumijo • Mineral Pitch • Asphaltum • Salajeet
Overview
Shilajit is a sticky, tar-like substance found primarily in the rocks of the Himalayas, formed over centuries from the slow decomposition of plants. It is rich in fulvic acid (60-80% of its composition), humic substances, and over 80 trace minerals. In Ayurvedic medicine, shilajit has been used for thousands of years as a rejuvenating tonic (rasayana). Modern research has validated several traditional claims, showing that purified shilajit can increase testosterone, improve mitochondrial function, enhance CoQ10 activity, and support male fertility. The key active component is fulvic acid, a powerful electrolyte that enhances nutrient absorption and cellular energy production. Quality and purity are critical — only purified shilajit from reputable sources should be used, as raw shilajit may contain heavy metals and contaminants.
Key Benefits
Testosterone Support
A clinical trial in healthy men aged 45-55 found that 250mg of purified shilajit twice daily for 90 days increased total testosterone by 20% and free testosterone by 19%. DHEA levels also increased significantly. The mechanism may involve enhanced Leydig cell function and reduced oxidative damage to testicular tissue.
Mitochondrial Energy & CoQ10 Enhancement
Shilajit's fulvic acid enhances mitochondrial function by improving electron transport chain efficiency. It also stabilizes CoQ10 in its active (ubiquinol) form, potentially doubling CoQ10's effectiveness. This translates to improved cellular energy production.
Mineral Absorption & Nutrient Transport
Fulvic acid is a natural electrolyte and chelator that enhances the absorption and transport of minerals and nutrients into cells. It can carry 60+ minerals and trace elements, improving their bioavailability.
Male Fertility
A study in infertile men found that 200mg of purified shilajit daily for 90 days increased sperm count by 61%, sperm motility by 12%, and serum testosterone by 23%. The antioxidant properties of shilajit protect sperm from oxidative damage.
Dosage & How to Take
The standard dose is 250-500mg of purified shilajit extract daily. Most clinical trials use 250mg twice daily (500mg total). Always use purified/processed shilajit — never raw.
| Purpose | Dose | Notes |
|---|---|---|
| Testosterone support | 250 mg twice daily (500 mg total) | Based on the clinical trial in healthy men |
| Energy & mitochondrial support | 250-500 mg/day | May enhance CoQ10 effectiveness |
| Male fertility | 200-500 mg/day for 90+ days | Longer duration for spermatogenesis effects |
| General wellness | 250 mg/day | Maintenance dose for mineral absorption and energy |
Best Time to Take
Take in the morning. Some users find it mildly energizing. Can be taken with or without food.
With or Without Food
Can be taken with or without food. Some people prefer taking with warm water or milk (traditional Ayurvedic method).
Forms & Bioavailability
| Form | Absorption | Best For | Notes |
|---|---|---|---|
| Purified Resin | High | Traditional form, highest potency | Sticky tar-like substance. Dissolve pea-sized amount in warm water. Must be from reputable source. |
| Purified Capsules/Tablets | Good | Convenience, standardized dosing | Standardized to fulvic acid content. Easier to dose consistently. |
| PrimaVie (Branded Extract) | High | Clinical-grade, most studied | Purified and standardized extract used in clinical trials. Heavy metal tested. |
Side Effects & Safety
Common
- Mild GI upset
- Metallic taste
- Increased body heat
Rare
- Allergic reactions
- Dizziness
- Increased uric acid (gout risk in susceptible individuals)
Contraindications
- Gout or hyperuricemia (may increase uric acid)
- Hemochromatosis (iron overload — shilajit contains iron)
- Never use raw/unprocessed shilajit (heavy metal contamination risk)
Interactions
Shilajit contains iron and enhances mineral absorption; may increase iron levels
May lower blood sugar; monitor glucose levels
May have mild blood pressure-lowering effects
