Introduction

Most Shilajit products claim to be pure, but only laboratory testing can prove it.
Advanced analytical methods like ICP-MS and AOAC 2015.01 ensure that the resin is safe, bioactive, and free from contamination.

1. Heavy Metal Safety (ICP-MS, USP <730>)

The Inductively Coupled Plasma Mass Spectrometry (ICP-MS) method detects heavy metals such as lead, arsenic, cadmium, and mercury at trace levels.
For Shilajit to be safe, results must stay within global limits:

• Lead < 0.5 mg/kg

• Arsenic < 1.0 mg/kg (total), < 0.2 mg/kg inorganic

• Cadmium < 0.3 mg/kg

• Mercury < 0.1 mg/kg

Labs like Eurofins, Anresco, and Alter Lab USA use this standard for global supplement safety compliance.

2. Fulvic Acid Quantification (AOAC 2015.01 & IRXNK)

These spectrophotometric methods measure fulvic acid precisely.
They replaced old gravimetric and UV tests that produced false highs.
True Shilajit typically measures 45–55% fulvic acid, a realistic biological range proven by modern chemistry.

3. Microbial and Purity Testing

Microbiological tests under ISO 4833-1 and FDA BAM ensure Shilajit is free from harmful microbes like E. coli and Salmonella.
Proper purification using distilled water and glass drying prevents contamination while preserving minerals.

4. Reading a Real Lab Report (COA)

A valid Certificate of Analysis includes:

• Lab name and accreditation (ISO/IEC 17025)

• Testing methods used (ICP-MS, AOAC, IRXNK)

• Fulvic acid percentage

• Heavy metal results

• Testing date and batch ID

If a report lacks these, it’s not a real verification.

Conclusion

Lab testing is not optional — it’s the only way to confirm that Shilajit is safe and effective.
ICP-MS ensures heavy metal safety, AOAC and IRXNK confirm potency, and ISO standards guarantee purity.
Consumers and researchers should trust only independently verified Shilajit tested under these recognized global standards.
