PAH4 and Shilajit: why these analyses are becoming important
PAH4 analyses are used to detect certain polycyclic aromatic hydrocarbons (PAHs) in shilajit.
They provide an additional level of control beyond more common analyses such as heavy metals or microbiology.
The shilajit market has grown significantly in recent years. However, not all brands communicate with the same level of transparency about the analyses actually performed.
Among the most technical controls is the analysis of PAH4. While little known to the general public, they can be an interesting indicator when trying to assess the credibility of a product.
What does PAH4 mean?
PAH4 stands for Polycyclic Aromatic Hydrocarbons 4.
The term refers to a group of four compounds often monitored in certain food safety controls:
- benz(a)anthracene;
- benzo(a)pyrene;
- benzo(b)fluoranthene;
- chrysene.
Important: PAH4 analyses do not replace conventional controls like heavy metals or microbiology. They are complementary.
Why analyse PAH4 in shilajit?
Shilajit is a complex organic and mineral substance. Like many natural materials, its quality cannot be assessed solely with marketing claims.
PAH4 analyses provide an additional control for certain potential organic contaminants.
Simply stating that a shilajit is “pure” is not enough.
The real question is: what contaminants were screened for, on which batch, with which laboratory, and what were the results?
PAH4, heavy metals, and microbiology: what are the differences?
| Analysis |
What it checks |
Why it's useful |
| Heavy Metals |
Lead, mercury, arsenic, cadmium depending on the controls. |
To assess certain mineral contaminants. |
| Microbiology |
Yeasts, molds, bacteria, or germs tested for. |
To control certain microbiological risks. |
| PAH4 |
Targeted polycyclic aromatic hydrocarbons. |
To add a control for certain organic contaminants. |
Why do few brands talk about PAH4?
PAH4 is a technical subject. Most brands prefer to communicate on simpler topics such as "Himalayan origin," "purity," or "fulvic acid."
However, PAH4 analyses can become an interesting indicator of transparency when clearly published with:
- an identifiable batch;
- an indicated laboratory;
- viewable results;
- analyses consistent with the product sold.
Strategic reading: when a brand publishes this type of analysis, it accepts a higher level of transparency than the market average.
How to read a PAH4 analysis on a certificate?
An analysis certificate should not be skimmed. Several elements need to be verified.
| Element |
Why it's important |
| Batch number |
The certificate must correspond to the product actually purchased. |
| Laboratory |
The laboratory must be identifiable. |
| Molecules tested |
The four PAH4s must be clearly indicated. |
| Results |
They must be legible and understandable. |
| Report date |
It allows verification of the timeliness of the analyses. |
Do PAH4 analyses influence the price of shilajit?
Yes, indirectly. Complementary analyses represent an additional cost for brands that choose to strengthen their controls.
This can explain part of the difference between:
- a product with very little documentation;
- and a product associated with detailed batch-specific certificates.
Price alone is not enough.
What truly matters is what is controlled, published, and verifiable.

FAQ — PAH4 and shilajit
What does PAH4 mean in shilajit?
PAH4 refers to four polycyclic aromatic hydrocarbons sometimes screened for in certain food safety controls.
Why are PAH4 analyses important?
They provide an additional control for certain potential organic contaminants.
Do PAH4s replace heavy metals?
No. PAH4 analyses complement heavy metal and microbiological controls.
How do I verify a PAH4 analysis?
You need to check the batch, the laboratory, the molecules analyzed, and the consistency of the certificate with the purchased product.
Do all brands publish PAH4 analyses?
No. Few brands clearly highlight this type of analysis in their public certificates.
Conclusion: PAH4 analyses represent an additional level of control that can help to better assess the transparency and seriousness of a shilajit.
