Why “75% Fulvic Acid” Claims in Shilajit Are a Red Flag

The Rise of Inflated Fulvic Acid Claims

“Contains 75% fulvic acid.” On the surface that sounds powerful. In practice, it’s usually marketing. Independent Certificates of Analysis (COAs) routinely show authentic Shilajit in the ~5–15% fulvic range. Anything far higher deserves scrutiny.

Why Percentages Can Be Misleading

Fulvic acid does not have a single universal test standard. Unlike heavy metals—where expectations are clearly defined—fulvic content can be measured by different methods that produce dramatically different values. That gap opens the door to exaggeration.

• LAMAR method: Considered one of the most advanced approaches for distinguishing fulvic and humic fractions; accurate but less commonly used in commercial testing.
• Outdated or loose methods: These can misread other organic compounds as “fulvic,” producing inflated percentages.

If a label claims “75% fulvic” but does not disclose how it was measured, treat the percentage as a marketing claim, not a scientific fact.

A Real-World Example

Some brands promote fulvic percentages that fall apart under independent testing. In one widely circulated case, a product advertised as “75% fulvic” tested just over 6% on an accredited COA—less than one-tenth of the claim. Without clear testing methods, it becomes easy to publish inflated numbers and difficult for buyers to verify them.

When High Numbers Are Real (But Not Natural)

Some products—such as standardized fulvic extracts like PrimaVe®—can legitimately test in the 75–90% fulvic range. The essential distinction is:

• They are concentrated extracts intentionally processed to increase fulvic content.
• They are not raw Shilajit resins and should not be labeled as such.

There is nothing inherently wrong with concentrated extracts, but labeling must be accurate. 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 natural whole-matrix resin.

Why Inflated Claims Are a Red Flag

• Lack of method disclosure: Without a named testing method, a percentage is just a number.
• Marketing inflation: Large percentages attract buyers but rarely match independent lab data.
• Value distortion: Paying premium pricing for a label claim that tests at a fraction of the number is a poor investment.
• Risk of adulteration: Some sellers may include additives that mimic “fulvic-like” signals on loose assays.

Pro Tip: If a product claims 50–75% fulvic acid and calls itself raw “Himalayan Shilajit,” ask for the COA and testing method. If it is really a standardized extract (e.g., PrimaVe®), the label should clearly say so.

The Bigger Issue: Testing Abuse

Because fulvic testing is not standardized, some brands take advantage of the ambiguity:

• Selecting labs known for producing larger numbers.
• Using vague reports that omit the method and detection limits.
• Percentage manipulation (e.g., reporting fulvic % relative to a fraction rather than the whole sample).

How to Protect Yourself

1. Look for method transparency. A fulvic percentage without a named method should be considered unreliable.
2. Check for additional testing. Reputable products also provide data on heavy metals (Pb, As, Cd, Hg), microbes, and sometimes ash content.
3. Expect regular updates. Trust brands that routinely publish new COAs rather than relying on a single historical report.
4. Understand typical ranges. Natural Shilajit typically falls around 5–15% fulvic, depending on region and material composition.

For broader expectations around safety and documentation, consult the WHO Guidelines for Quality Control of Herbal Materials and the USP resources on elemental impurities.
