Why we test every batch
Shilajit is a mineral-rich resin, which means a poorly sourced or badly processed product can concentrate heavy metals. That’s exactly why testing matters. Every batch we sell is checked by an independent UK laboratory before it’s released, so you know exactly what’s in the jar.
What we test for
- Heavy metals, lead, arsenic, mercury, and cadmium, by an ISO 17025 accredited method.
- Fulvic acid content, to confirm potency, not just purity.
- Humic acid and total humic extract, the active fraction that defines genuine Shilajit.
- Dry matter, so you know how much is resin and not water.
