Total transparency: our certificates of analysis
At WinaBio, we believe thattrust is earned through transparency. This is why we publish information on the quality controls that each batch of Shilajit undergoes.
Our quality control process
Each batch of Shilajit WinaBio goes through a multi-step verification process:
🔬Step 1 — Analysis at source
Before importing, Shilajit is analyzed on site to verify its basic composition: fulvic acid content, mineral profile, and absence of coarse contaminants.
🧪Step 2 — Purity Testing
Tests are carried out to verify the absence of heavy metals (lead, mercury, arsenic, cadmium) beyond European regulatory thresholds, the absence of microbiological contamination (bacteria, molds, yeasts), and the absence of pesticides and residual solvents.
📊Step 3 — Checking the composition
Fulvic acid content and mineral profile are checked to ensure compliance with product specifications.
✅Step 4 — Regulatory Compliance
The product is checked for its compliance with current European regulations concerning food supplements (Directive 2002/46/EC, EC Regulation 1169/2011).

Why is it important?
Shilajit is a natural mineral extracted from mountain rocks. Without rigorous purification and control, it may contain traces of heavy metals or natural contaminants. Cheap and untested Shilajit can be dangerous for your health. By choosing WinaBio, you choose security and transparency.
