Specifying Shilajit Powder
The powder is purified, not concentrated. Where a dose is built on fulvic acid, specify the extract; where the label names shilajit itself or the format is traditional, the powder is the right material.

|---|---|---|---|---|---|---|
| Purified powder, 40 mesh | Fulvic acid reported per lot | Gravimetric | Free-flowing powder, NLT 95% through 40 mesh | Capsules, Ayurvedic formulations | Standard | Request Purified powder, 40 mesh |
| Purified powder, 80 mesh | Particle size | Sieve | Fine powder | Blends and sachets needing finer dispersion | On request | Request Purified powder, 80 mesh |
| Purified resin | Moisture and fulvic acid reported | Gravimetric | Semi-solid paste | Resin formats, further processing | On request | Request Purified resin |
Standard grades are held and supplied routinely; grades on request are produced against a confirmed order. Other standardisations, mesh sizes and packs can be quoted to specification.

Shilajit Powder is purified shilajit (Asphaltum punjabianum), dried and milled to a free-flowing powder. It is not concentrated or standardised, so its fulvic acid content is reported at the natural level of each lot.
Shilajit Powder is purified material at its natural composition, whereas Shilajit Extract is standardised to a defined fulvic acid level, such as 20%, 50% or 70%. Where a formulation is dosed on fulvic acid, the extract is usually the appropriate choice.
Depending on the application, relevant parameters can include identity, purification, fulvic acid, moisture, particle size, microbiological quality and heavy metals. Lead, arsenic, cadmium and mercury are reported as figures by ICP-MS for every lot.
Yes. Particle size can be specified as part of the enquiry, and purified shilajit resin can be discussed where a semi-solid form is required, subject to the agreed specification and availability.
Yes. Samples can be arranged for evaluation and formulation trials, subject to availability. Shilajit is hygroscopic, so samples and bulk material should be kept sealed in cool, dry conditions.
