What the Lab Tests Cover
Fulvic Acid Content
The primary active compound in Shilajit. 60%+ is considered good quality; 70%+ is high quality. Our Capsules test at 79.22% and our Resin at 76.74% — both significantly above the industry benchmark. Products without a verified fulvic acid percentage may be diluted or adulterated.
Heavy Metal Screening
Raw Shilajit can contain arsenic, cadmium, lead, and mercury. Eurofins tests all four metals on every batch. Both our Capsules and Resin pass within safe limits every time. This is non-negotiable for a product taken daily.
Microbial Safety
Eurofins also screens for microbial contamination as part of our standard batch testing protocol.
