Shilajit Explained: Fulvic Acid, Sourcing, and How to Choose a Quality Extract
Quick answer: Shilajit is a mineral-rich resin formed naturally in mountain rock over centuries, most commonly sourced from the Himalayas. Its main studied compound is fulvic acid. The single most important thing to check before buying any shilajit product is third-party heavy metal testing - because of how it forms geologically, unpurified or poorly tested shilajit can contain lead, mercury, arsenic, or cadmium, which is a genuine, well-documented risk in this category specifically.
What Shilajit Actually Is
Shilajit forms over centuries as plant and mineral matter decomposes and compresses in mountain rock, most notably in the Himalayas. It's traditionally collected as a sticky, resin-like substance, rich in minerals and fulvic acid - the compound most modern research on shilajit focuses on.
The Purity Issue You Should Actually Care About
This is worth taking seriously rather than glossing over: because shilajit forms from rock and mineral deposits, it can pick up heavy metals from its geological surroundings. Independent testing of commercial shilajit products has found meaningful variability in heavy metal content between brands, even among products labelled "purified." That's not a reason to avoid shilajit altogether - it's a reason to be specific about what you check before buying:
- Third-party lab testing, not just a manufacturer's own internal claim
- A Certificate of Analysis (COA) available on request, showing actual heavy metal test results
- Reputable sourcing - high-altitude Himalayan sources are generally well regarded, though region alone doesn't guarantee purity without testing
Resin vs Capsules
Traditional shilajit is sold as a raw resin, a small amount dissolved in warm water or milk. Capsules use a processed, standardised extract - generally easier to dose consistently, and the more common format in UK supplement retail, including ours.

Some combination products pair shilajit with ingredients such as ashwagandha or lion's mane. If you're interested in understanding the differences between extracts, see our guide to KSM-66 Ashwagandha and how it differs from standard extracts.
FAQ
Is shilajit safe to take daily?
Many people take it as a daily supplement, but purity and sourcing matter more here than with most other supplement categories - stick to products with third-party testing.
What does "fulvic acid percentage" on the label mean?
It's a measure of one of shilajit's key studied compounds - higher isn't automatically better, but it's a useful indicator of a standardised, quality-controlled product rather than raw, untested resin.
Can I take shilajit with other supplements?
Generally yes, though as with any new supplement, check with a pharmacist or GP if you're on regular medication.
Is Himalayan shilajit better than other sources?
It's a generally well-regarded source region, but region alone doesn't guarantee purity - testing is what actually confirms safety, regardless of where it's from.
