Last updated: January 2026 | Reading time: 8 min

⚠️ In summary

Shilajit is not inherently dangerous , but it can become so if the product is of poor quality. More than 90% of the shilajit sold worldwide is estimated to be adulterated or contaminated with heavy metals. The key is to choose purified shilajit, tested in an independent laboratory , with an accessible certificate of analysis. At Ômara, our Eurofins Switzerland tests guarantee heavy metal levels of less than 0.01 ppm.

You've heard about the benefits of shilajit — energy, mental clarity, recovery — but you're wondering if this Himalayan resin is really safe ? That's a legitimate question.

This article reviews the real risks , possible side effects , contraindications , and above all, how to consume shilajit safely .

Is shilajit dangerous?

Short answer: no, if the product is of good quality .

Shilajit has been used in Ayurvedic medicine for over 3,000 years. Millions of people consume it regularly without any problems. Available scientific studies report no toxic effects from properly purified shilajit at recommended doses.

✅ What science says

A 2024 systematic review (Frontiers in Pharmacology) concluded that purified shilajit is "generally well tolerated" with a "favorable safety profile" at standard doses (300-500 mg/day). Reported adverse effects are rare and mild.

The problem is not the shilajit itself, but the quality of the products sold.

The real dangers: unpurified shilajit

Raw shilajit, as it comes from the rock, can contain dangerous impurities . This is why rigorous purification is essential.

1. Heavy metal contamination

The main risk associated with poor-quality shilajit is the presence of heavy metals : lead, arsenic, mercury, and cadmium. These substances can accumulate in the body and cause serious long-term health problems.

Alarming study: An analysis published in the Journal of Clinical Toxicology revealed that several samples of shilajit sold online had toxic levels of lead and arsenic , far exceeding safety standards.

2. Counterfeit and diluted products

It is estimated that over 90% of the shilajit sold worldwide is counterfeit . Common scams include:

  • Dilution with earth, charcoal or other substances
  • Synthetic Shilajit made in a laboratory
  • Mixtures with undeclared substances
  • Inflated fulvic acid levels (reported 80%, actual 30%)
