Why Testing Matters More Than Ever
Shilajit is often marketed as a “miracle resin,” but the global supplement space is riddled with mislabeling, fillers, and counterfeits. Some brands boast “75% fulvic acid” on the label—numbers that collapse under real lab scrutiny. In one well-known case, independent testing found a product claiming 75% fulvic actually contained a tiny fraction of that. Purity isn’t just about marketing—it’s about safety. Before you invest in a jar, use the simple at-home checks below and follow up with a batch-matched Certificate of Analysis (COA).

The Three Keys: At-Home Tests That Really Work
Most lists share a dozen tricks; these three give the clearest signal without special gear.
1) Warm Water Dissolution Test
Place a rice-grain to pea-size amount in a glass of warm water.
- Authentic: dissolves smoothly into a uniform brown/amber solution; minimal residue; no oily film.
- Adulterated: gritty sediment, rainbow-like oil sheen, stubborn clumps that refuse to dissolve.
Why it works: Fulvic/humic complexes are naturally water-soluble. If a “resin” resists dissolving, binders or fillers are likely at play.
2) Odor & Texture Test
Use your senses.
- Authentic: earthy, tar-like aroma; pliable at room temp; softens in warm fingers.
- Adulterated: chemical/perfumed/syrupy notes; brittle glassy shards or unnaturally sticky film.
Why it works: Natural resins form slowly and carry complex organic volatiles; synthetic perfumes or solvent residues can’t replicate that profile cleanly.
3) Cooling Elasticity Test
Chill a pea-size dab 5–10 minutes, then flex it.
- Authentic: firms when cold but retains slight elasticity—bends or stretches gently without shattering.
- Adulterated: snaps like brittle candy or stretches like plastic (common with waxes/plasticizers).
Why it works: The native matrix of fulvic acids, minerals, and organics holds elastic integrity; additives disrupt it.
Pro Tip: If a brand’s “purity” passes these screens but they won’t share a batch-matched COA, that’s your signal to move on.
The Lab Proof That Matters
At-home checks help you screen products, but they do not confirm safety. A trustworthy COA should:
- Match your batch/lot number
- List fulvic %, heavy metals (Pb/As/Cd/Hg), and microbial results
- Name standardized methods from an accredited lab (ISO/IEC 17025)
For context on industry expectations, see the WHO guidelines for quality control of herbal materials and the USP resources on elemental impurities.
Why American Grit Sets the Standard
Most sellers lean on stories; we lean on data. American Grit publishes batch-matched COAs showing fulvic levels, heavy metals, and microbial safety—sourced from U.S. deposits and extracted with water and fermentation (no harsh solvents, no shortcuts). If you’re here for the benefits tied to fulvic acid, skip the guesswork and compare the receipts.

Start with three screens: warm-water dissolution (should dissolve smoothly), odor/texture (earthy/tar-like, pliable), and a brief cooling elasticity test (firms but stays slightly elastic). These flag obvious fakes, but always confirm with a batch-matched COA.
No. At-home checks are only a screen. Real proof is a third-party, batch-matched COA that lists fulvic %, heavy metals (Pb/As/Cd/Hg), microbial results, detection limits, and named methods from an accredited lab.
Grit that won’t dissolve, rainbow-like oil sheen, perfume or chemical smell, brittle snap when cold, and waxy or plastic-like stretch. Any of these suggest fillers or adulteration.
A lot number matching your jar, fulvic % with the method named, ICP-MS metals results, microbial testing, detection limits (LOD/LOQ), and the lab’s accreditation (e.g., ISO/IEC 17025).
