How to choose shilajit: 6 verifiable criteria
How to choose shilajit: 6 verifiable criteria
Shilajit is a natural resin that forms in rocks at high altitudes. Its composition varies from batch to batch, and the market is highly inconsistent. Here are the points that allow you to compare products based on evidence rather than promises.
1. An analysis report corresponding to your batch
The batch number printed on the jar must correspond to a specific report. A generic certificate, without a batch number or date, proves nothing about the product you receive.
2. A named independent laboratory
Look for the name of the laboratory (for example, Eurofins or TÜV SÜD), the date of the report, and the method used. A report published as a downloadable PDF is more verifiable than a simple "laboratory tested" claim.
3. Heavy metals, with figures
Lead, cadmium, mercury, and arsenic must appear with a value in mg/kg, not just "compliant". Test results have a margin of error: it must be indicated.
4. Arsenic: total and inorganic
Total arsenic includes all its forms. Inorganic arsenic is what laboratories monitor most closely. A serious report distinguishes between the two. In our latest Eurofins report (June 2026), we measured 0.71 ± 0.16 mg/kg of total arsenic and 0.15 ± 0.09 mg/kg of inorganic arsenic.
5. Fulvic acids: information, not a verdict
The fulvic acid level indicates the composition, not the purity or effectiveness. It varies depending on the resins and the measurement method. Our resin is 56.2% fulvic acid on a dry matter basis according to Eurofins. Other products claim higher values: always compare the method and calculation basis (dry matter or raw product) before drawing a conclusion.
6. Microbiology and product form
Microbiological tests (for example, Salmonella and E. coli) complement the analysis of contaminants. Also check the form: a pure resin, without unnecessary additives, is easier to read than a mixture.
Summary
| Criterion | What to look for |
|---|---|
| Batch | Number on the jar = number on the report |
| Laboratory | Name, date, method, PDF |
| Heavy metals | Lead, cadmium, mercury, arsenic in mg/kg |
| Arsenic | Total and inorganic separated |
| Fulvic acids | Level + measurement method |
| Microbiology | Results indicated |

Frequently asked questions
Does a high fulvic acid level prove quality? No. It describes the composition, not the absence of contaminants or effectiveness.
Why ask for the batch report? Because a natural product varies from batch to batch.
Is an analysis report enough to guarantee safety? It documents the tested batch. In case of pregnancy, breastfeeding, illness, or treatment, ask for the advice of a doctor or pharmacist.
