Shilajit shoppers are bombarded with numbers: “50% fulvic,” “75% fulvic,” “highest concentration.” These sound impressive—but few realize there’s currently no single, universally adopted testing standard for fulvic acid. That gap lets brands lean on looser methods, publish inflated percentages, and hide behind vague COAs. This explainer looks at why fulvic is hard to measure, how more selective methods like the LAMAR approach raise the bar, and what you should check before trusting any label claim.
Why Fulvic Is Hard to Measure
- Fulvic isn’t one molecule. It’s a broad class of organic acids—more like a family than a single compound.
- Methods vary widely. Some labs measure total organic acids; others rely on color reactions that can also detect non-fulvic material.
- Older or less selective assays can inflate results. They may count humics, ash, or other organics as “fulvic,” pushing the headline percentage higher than it really is.
Result: one method might say 60–75% while a stricter method on the same sample shows ~5–15%. Both are “results,” but only the more selective test is closer to what buyers typically think they’re paying for.
Enter the LAMAR Approach
The LAMAR approach is often described in the technical literature as a more precise modern technique for separating fulvic from other humic fractions. Compared with many legacy tests, LAMAR-type methods aim to:
- More clearly distinguish fulvic vs. humic substances, reducing cross-counting.
- Reduce interference from unrelated organic matter.
- Provide more repeatable, verifiable results across labs using similar protocols.
Because of this, more selective testing often reads many “high-fulvic” products lower—frequently in the realistic ~5–15% range for natural Shilajit. Lower numbers are not a defect; they’re usually a truer picture of reality when you measure more precisely.
When High Numbers Are Real (But Not Natural)
Some products—such as standardized fulvic extracts like PrimaVe®—can legitimately show very high percentages (for example, 75–90%). The key distinction is:
- They’re standardized concentrates produced through controlled processing to boost fulvic levels.
- They are not raw Shilajit resins and should not be presented as such.
Comparing a concentrated fulvic extract to natural Shilajit is like comparing vitamin C isolate to an orange: one is engineered for potency; the other is a whole-matrix resin. If a label claims “raw Himalayan Shilajit at 75% fulvic,” it’s reasonable to ask for the method and COA before you accept the claim.
How Inflated Claims Happen
- Method shopping: choosing less selective assays that tend to read higher.
- Vague COAs: reporting a percentage with no method, no detection limits, and no information about lab credentials.
- Percentage “gymnastics”: reporting a percentage relative to a fraction rather than the entire sample.
Pro Tip: If a brand touts big numbers but won’t disclose the method (for example, whether it used a more selective approach vs. unspecified colorimetry), treat the percentage as marketing—not measurement.
What Buyers Should Look For on a COA
- Clear identification: the COA should clearly identify the product or lot being tested.
- Named methods: fulvic test method disclosed (with enough detail to understand the approach); ICP-MS/ICP-OES for heavy metals; appropriate microbial assays.
- Lab credentials: evidence of accreditation such as ISO/IEC 17025 or equivalent on the report.
- Reasonable ranges: Natural Shilajit commonly tests around ~5–15% fulvic with more selective methods; very high values generally indicate either a standardized extract or a need for closer scrutiny.
For broader quality context, review the WHO Guidelines for Quality Control of Herbal Materials and the USP resources on elemental impurities.
Why This Matters for Shilajit Buyers
Shilajit can be vulnerable to adulteration (fillers, perfumes, waxes) and contamination with heavy metals or microbes. Inflated “fulvic %” claims can make lower-quality products appear premium. Without method transparency, consumers cannot easily compare products or understand what they are truly getting.
Proof Over Promises
American Grit publishes COAs for each lot, including fulvic %, heavy metals, and microbial results—with test methods disclosed. Our fulvic minerals are U.S.-sourced and produced via water extraction + fermentation (no harsh solvents, no added perfumes, no sweeteners). The goal is simple: help buyers evaluate data, not just marketing language.

For natural resins, that level is unlikely. More selective testing methods often find natural Shilajit in the ~5–15% fulvic range. Very high percentages are usually associated with concentrated fulvic extracts or with less selective testing approaches. Always request a certificate of analysis (COA) with the testing method included.
No. The term “Himalayan” is frequently used as a marketing phrase. True quality depends on lab testing (including heavy metals, microbial safety, and fulvic measurement), not just geographic claims.
A COA is helpful only if it clearly identifies the product, comes from a reputable lab, and lists the analytical methods used. Be cautious with reports that are undated, lack methods, or appear generic rather than specific to the product you purchased.
Authentic Shilajit is typically a single natural substance. Extra ingredients such as sweeteners, preservatives, or proprietary blends may indicate dilution or adulteration.
Price alone does not prove quality. Some products are expensive because of branding, while others reflect the cost of careful sourcing and testing. The most reliable indicator of quality is transparent third-party lab data and clear communication about how the product is analyzed.
