Himalayan and Altai Shilajit: Composition Evidence Report
Himalayan and Altai Shilajit: Composition Evidence Report
This report from The Yeti Life summarises what laboratory studies have measured about how shilajit composition varies by origin. Multi-region studies do find differences in metals, phenolic acids and inorganic anions. None of the studies found for this report sampled shilajit labelled as Altai, and none compared fulvic acid content by region — so a region name on a pack is not, on this evidence, a measure of what is inside it.
Studies that analysed shilajit from more than one origin
| Study | Samples and origins | Method | Measured finding |
|---|---|---|---|
| 2026 · J Trace Elem Med Biol · PMID 42364294 | 12 samples from diverse geographical origins | ICP-MS, AF4-ICP-MS, size-exclusion chromatography | Distinct variability in major metals (calcium, magnesium), essential elements (iron, zinc, manganese) and toxic elements (including cobalt, nickel, lead, cadmium, mercury). Calcium, the most abundant element, present as a calcium-lactic acid complex. |
| 2026 · PMID 41699045 | 11 samples from Iran, India, Nepal, Russia and Kyrgyzstan | HPLC-MS/MS | Gallic acid the most abundant phenolic acid, reaching 2839.28 µg/g in an Iranian sample; rosmarinic acid 216.26 µg/g in one Iranian sample. Most samples held more hydroxybenzoic than hydroxycinnamic acids. |
| 2025 · PMID 40223103 | 14 raw samples from Iran, India, Nepal, Kyrgyzstan and Russia; 6 commercial supplements | Inorganic anion quantification | Chloride 0.102–9.496 mg/g in raw samples and up to 0.931 mg/g in supplements; fluoride quantifiable in one sample only (0.064 mg/g). Origin significantly influenced anion composition. |
| 2026 · PMID 42357568 | 3 commercial samples from Russia, Nepal and Iran | Phenolic acid profiling | Phenolic composition differed markedly between samples; the Iranian sample had the highest total quantified phenolic acids. |
| Review, 2025 · Crit Rev Anal Chem · PMID 38133965 | Published literature | Review | More than 80 % of shilajit weight is humic substances and about 20 % is calcium, potassium and magnesium; composition differs between regions. |
What is not known
- No study found here sampled shilajit labelled Altai. The closest samples are labelled Russia and Kyrgyzstan, which do not necessarily come from the Altai range.
- No study found here compares fulvic acid content by region. Region claims about fulvic acid percentages are not supported by these sources.
- Region labels on retail packs are not verified by any of these studies.
What this means when buying
Composition varies from sample to sample within and across regions, so the useful document is a certificate for your batch, not a region name. Our own certificate reports fulvic acid and heavy metals for a single batch; it does not certify geographic origin.
