Measured: potassium, calcium, magnesium, iron and more
The Lab Reports
Issued to Himalayan Foods (Pvt) Ltd, Gilgit, the supplier of Purkafoor resin. Midwest Laboratories report 21-141-4178 (May 2022) and Eurofins report AR-24-KV-006127-02 (17 June 2024).
Heavy metals
ppm = mg per kg. "Per daily dose" is what a 500 mg serving (the top of the usual 300–500 mg dose) would contain at the higher of the two results, compared with the daily exposure limit for supplements in USP <2232>.
| Metal | Midwest Labs (2022) | Eurofins (2024) | Per daily dose | Daily limit (USP <2232>) |
|---|---|---|---|---|
| Lead (Pb) | 2.00 ppm | Not detected (< 0.01) | 1.0 µg | 5 µg |
| Arsenic (As) | 1.15 ppm | 0.301 ppm | 0.58 µg | 15 µg |
| Cadmium (Cd) | 0.133 ppm | 0.024 ppm | 0.07 µg | 5 µg |
| Mercury (Hg) | 0.01 ppm | Not detected (< 0.01) | 0.005 µg | 15 µg |

| Moisture | 13.82 g per 100 g (Eurofins), 17.5% (Midwest) | Both |
Fulvic acid was not measured in these reports, so we do not quote a fulvic acid percentage. Results apply to the samples the labs received; the labs did not collect the samples themselves. Midwest Laboratories report 21-141-4178, analysed May 2022. Eurofins report AR-24-KV-006127, sample (batch SSS3301UA) received 26 May 2024, reported 17 June 2024. Both reports are issued to our supplier, Himalayan Foods (Pvt) Ltd, Gilgit. Work out any report at your own dose with the heavy-metal calculator.
Why Third-Party Lab Testing Matters
Raw Shilajit naturally oozes from high-altitude rock crevices in the Himalayas. Because it is harvested from mountain rock face, untreated raw crude contains stone particles, micro-debris, and fluctuating minerals.
Our resin is purified in spring water and filtered several times, without chemical solvents. Shilajit naturally contains small amounts of metals from the rock it forms in, so the useful question is how much a daily dose contains. The tables above answer that with the labs' own numbers.
Simple Home Verification Tests
These quick checks at home help you spot obvious fakes. They cannot measure purity or heavy metals; only a lab can.
- Complete Water Solubility: Pure resin dissolves 100% in warm water or milk in minutes, turning the liquid golden-amber without leaving any sand, silt, or gritty residue at the bottom.
- Temperature Reaction: Natural resin turns soft and pliable with the warmth of your hands, but becomes glass-brittle and shatters into clean shards when placed in a freezer.
- No Burning Smoke: Pure resin will bubble, expand, and char upon flame contact without catching fire or producing pungent plastic smoke.
