Why Third-Party Testing Matters for Shilajit — and How Equil Tests Every Batch

With Shilajit, testing isn't a marketing badge — it's a genuine safety and quality requirement. Here's what it covers, and exactly how Equil does it.

Unlike most dietary supplements, Shilajit comes from mountain rock and must be purified of naturally occurring heavy metals before it's safe to consume. Without independent verification, there's no reliable way to know whether a product has been properly purified — or whether it contains what the label claims. Third-party testing closes that accountability gap.

Why it matters more for Shilajit than most supplements

The supplement industry operates with relatively limited regulatory oversight, so brands can make claims that are hard for consumers to verify. For Shilajit specifically, this matters more: the source material carries a genuine heavy metal risk that proper purification must address — and only independent testing can confirm it's been done. Testing by an independent, accredited laboratory is the mechanism that turns a claim into a verifiable fact.

What third-party testing covers

Fulvic acid content: verifies the claimed concentration of the primary quality and potency compound. See Why Fulvic Acid Percentage Matters.

Heavy metals: lead, arsenic, mercury, cadmium and others that can be present in raw Shilajit. See Why Heavy Metal Testing Matters.

Mycotoxins & microbial contamination: fungal toxins and harmful bacteria are screened for and confirmed absent.

Authenticity markers: some testing confirms the characteristic compound profile of genuine Himalayan Shilajit — including DBPs and humic substances — beyond fulvic acid alone.

Claims vs verification

In the Shilajit market, claims are cheap. "High fulvic acid." "Premium Himalayan." "Maximum potency." These phrases appear on products across the entire quality spectrum. The difference between a claim and a verified fact is one thing: an independent laboratory Certificate of Analysis (COA) showing the actual tested result.

Fulvic acid content can't be judged by appearance, taste, or colour — it requires chemical analysis by an accredited lab. A brand claiming high content without an independent COA is asking you to trust them, not to verify them. That's why the gold standard is batch-by-batch testing from a named external laboratory, with results published openly rather than kept on file.

How Equil tests every batch — in New Zealand

Equil tests every batch of Shilajit through Hill Laboratories, an independent, accredited New Zealand laboratory, before a single tablet reaches a customer. Testing in the country of sale creates a level of accountability overseas documentation can't: results are subject to NZ standards, directly verifiable by NZ customers, and locally accountable.

Each batch follows the same process:

• New stock is received in NZ and held in quarantine before release
• A representative sample is submitted to Hill Laboratories for analysis
• Testing covers heavy metals, fulvic acid content, mycotoxins, and microbial safety
• Results are reviewed against established standards — only batches that pass every parameter are released
• Passing results are published openly at equil.co.nz/pages/third-party-test

Equil's current verified result is 76.9% fulvic acid — independently confirmed, documented in a Certificate of Analysis, with heavy metals within established safe limits. If a batch doesn't meet standards, it doesn't ship. That's the point of testing every batch rather than certifying once.

Key points

• Safety is the primary driver: heavy metal safety in Shilajit cannot be assumed — it must be verified
• Independent means a named external lab: in-house testing isn't equivalent
• Every batch, not just once: quality varies between batches — the best brands test each one
• Published beats filed away: transparency is the standard — results any customer can check
• Equil's standard: Hill Laboratories, NZ; verified 76.9% fulvic acid; batch results published

FAQs

What is a Certificate of Analysis (COA)?
The document a third-party lab produces after testing — listing the parameters, the results, and the lab's accreditation. It's the primary document to request or find published when evaluating a Shilajit product.

Which laboratory does Equil use?
Hill Laboratories, an independent accredited laboratory in New Zealand. The lab name, batch details, and results are all published at equil.co.nz/pages/third-party-test.

Why does testing in NZ rather than overseas matter?
A COA from an unfamiliar overseas lab is hard for a NZ customer to independently confirm. NZ-based testing from a recognised local lab is directly verifiable and subject to the same regulatory environment our customers operate in. Accountability is local.

What happens if a batch fails?
It doesn't ship. Testing only means something if it has consequences — batches that don't meet our heavy metal or fulvic acid standards are not released.

Is fulvic acid testing the same as heavy metal testing?
No — separate tests measuring different things. Heavy metal testing is a safety screen; fulvic acid testing is a quality and potency measure. Equil runs both on every batch.

Can I trust a brand that says "tested" without publishing results?
No — an unpublished claim is unverifiable. Any brand can say they test; only brands that publish their COAs are accountable for it.
