It is the right question to ask about shilajit, and we would far rather you asked it here than after buying something else. Raw resin is scraped off rock, and rock carries lead, arsenic, mercury and cadmium. Unpurified shilajit sold in a jar is a genuine risk.
Ours is purified before it ever becomes a gummy, and every batch is analysed by an independent laboratory — against the EU supplement limits for lead, cadmium and mercury, and against our own ceiling for arsenic, where the EU sets no supplement limit at all. A batch that fails does not ship.
And we hold the batch against the daily serving, not against the milligram of powder, because a metals panel measures concentration while what actually reaches you is concentration times dose. At 3,000 mg a day that multiplier is six times a typical serving. Doing that sum is the part of this category that goes quiet — dose low, print shilajit on the label, hope nobody asks.
