Shilajit is getting attention in testosterone circles. You will find it in supplement stacks, discussed on forums, and marketed as an ancient mineral resin with powerful hormonal effects.
So what is the actual evidence? And is it worth your money?
This article breaks down what shilajit is, what research has studied it, what the results show, and how to separate quality products from garbage.
What Is Shilajit?
Shilajit is a mineral-rich substance that seeps from rocks in mountain ranges, primarily the Himalayas. It has been used in Ayurvedic medicine for thousands of years, typically referred to as a “rasayana” — a substance believed to promote longevity and vitality.
Chemically, shilajit is a complex mixture of humic substances, fulvic acid, and more than 84 minerals. The key bioactive component is fulvic acid, which is claimed to support cellular energy and nutrient absorption.
The Testosterone Research
2015 Study in the Journal of the International Society of Sports Nutrition
Researchers gave 500mg of purified shilajit daily to healthy men for 90 days. The treatment group showed significant increases in total testosterone, free testosterone, and DHEA (a testosterone precursor) compared to placebo.
2012 Study on Oligospermia
Men with low sperm count given shilajit showed improvements in testosterone levels and sperm motility. Not directly about testosterone production, but the hormonal effects were consistent.
Quality Matters Enormously
This is critical: shilajit from unverified sources can be contaminated with heavy metals, fungal toxins, or adulterated with cheaper materials. Only use shilajit from suppliers that provide third-party testing.
Look for:
- Purified shilajit — raw shilajit needs processing to remove impurities
- Certificate of Analysis — third-party tested for heavy metals and microbial contamination
- Standardized fulvic acid content — ensure consistent dosing
Practical Take
Shilajit has more research behind it than most testosterone supplements. The 2015 JISSN study is particularly compelling. If you want to add it to your stack, make sure you are buying from a reputable source — the risk of contaminated product is real.
Dose: 500mg daily of purified/standardized shilajit extract
