Lab Results & Shilajit Comparison Guide

Shilajit Lab Results & Brand Comparison Guide

Independent Eurofins certificates, verifiable report codes, and an honest comparison of what's available in the UK market

The short version: Most Shilajit brands in the UK do not publish independent lab certificates or state their fulvic acid percentage. 5 Rivers Nutrition publishes full Eurofins certificates for every batch — with report codes you can verify independently. Our Capsules test at 79.22% fulvic acid and our Resin at 76.74%.

Our Eurofins Lab Results

Every batch of Shilajit Gold+ is independently tested by Eurofins Analytical Services — one of Europe's largest UKAS-accredited independent testing laboratories. Testing covers fulvic acid content and heavy metals (arsenic, cadmium, lead, mercury).

Table reflects publicly available information as of May 2026. Fulvic acid percentages for third-party brands are based on published marketing claims where available; independent verification is the buyer's responsibility.


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.


Questions to Ask Any Shilajit Brand

  • What is the fulvic acid percentage — and is it independently verified?
  • Which laboratory tested it, and are they UKAS-accredited?
  • Can I see the actual report code and verify it myself?
  • Are heavy metals (arsenic, cadmium, lead, mercury) all tested?
  • Is the product GMP-certified?
