Shilajit is usually processed into a powder or taken in a purified resin form. The exact composition of shilajit can vary based on geographical region, which may also impact its biological effects.^[1] Ideally, a product should be standardized to contain a certain amount of fulvic acid, DBPs, and DCPs. For example, PrimaVie — a patented, purified shilajit extract used in many trials — is standardized to contain ≥50% fulvic acid and ≥10.3% DBPs/DCPs.

In clinical trials, shilajit dosing has ranged from 200 to 2000 mg daily, although the most commonly used dosing regimen seems to be 500 mg daily, split into two daily doses. Research on shilajit is in the early stages; therefore, optimal dosing regimens for particular outcomes still need to be determined.
