Shilajit testing: heavy metals, analyses and certificates
Share
Shilajit is a powerful natural mineral resin, but also one of the most safety-sensitive dietary supplements. Its high mineral content means there is a potential risk of contamination if it is not properly purified and controlled.
This page explains in detail how shilajit tests are carried out , which heavy metals need to be analyzed, how to read a certificate of analysis (COA) and what criteria allow you to identify a truly safe shilajit in Switzerland.
Why testing the shilajit is essential
Shilajit forms in rocky environments over very long periods of time. It naturally concentrates minerals from its geological surroundings. This characteristic explains both its traditional interest and its potential risk.
Without rigorous testing, a shilajit may contain:
- heavy metals in problematic quantities,
- microbiological contaminants,
- mineral impurities not removed.
Systematic analytical control is therefore not optional, but fundamental.
Which heavy metals need to be analyzed?
Safety analyses of shilajit focus primarily on four heavy metals:
- Lead (Pb) : neurotoxic in the long term.
- Mercury (Hg) : can affect the nervous system.
- Arsenic (As) : toxic even at low chronic doses.
- Cadmium (Cd) : accumulates in the body.
These elements must be present at levels strictly below the European regulatory thresholds applicable to food supplements.
Reference method: ICP-MS analysis
The most reliable method for analyzing heavy metals in shilajit is ICP-MS (Inductively Coupled Plasma – Mass Spectrometry).
This technique allows:
- extremely precise detection at trace levels
- the simultaneous identification of several elements,
- reproducible and comparable results.
Any serious manufacturer should explicitly state the use of this method in its quality controls.
What is a Certificate of Analysis (COA)?
A certificate of analysis, or COA , is an official document issued by an independent laboratory. It attests to the results obtained during tests carried out on a specific batch of product.
A reliable COA must contain:
- the analyzed batch number,
- the analytical method used (e.g., ICP-MS),
- the measured values for each heavy metal,
- the name and contact details of the laboratory.
The absence of an accessible COA is a significant warning sign.
Why the analyses must be performed in batches
Since shilajit is a natural product, its composition can vary from batch to batch. A single or outdated analysis does not guarantee the quality of subsequent batches.
Good practices require:
- repeated analyses for each batch,
- clear traceability between the product and its Certificate of Authenticity (COA),
- a regular update of the results.
Purified Shilajit vs. Uncontrolled Shilajit
A purified and tested shilajit differs greatly from an untested product:
- increased safety of use,
- improved regulatory compliance
- transparency towards the consumer.
Conversely, products without published analyses rely solely on marketing claims.
Example of shilajit analyzed in Switzerland
In Switzerland, some manufacturers choose to publish their analyses transparently. This is notably the case for shilajit offered by Ômara , whose batches are analyzed by an independent laboratory in Switzerland using recognized methods.
Certificates of analysis allow verification of:
- compliance with heavy metal thresholds,
- consistency between the batch and the marketed product,
- the overall quality approach.

How to use these criteria to choose a shilajit
Before buying a shilajit, it is recommended to always check:
- the presence of ICP-MS analyses,
- access to batch analysis certificates,
- the name of the analysis laboratory,
- consistency between results and European standards.
These criteria are far more reliable than marketing claims or promises of effectiveness.
Conclusion
Shilajit testing is not a technical detail, but the very foundation of its safety. In Switzerland, a trustworthy shilajit relies on independent analyses, accessible certificates, and complete transparency.
Understanding these elements allows you to make an informed and responsible choice.
