ShilajitDB has independently reviewed and graded 246+ shilajit products sold in the United States. Every product is assessed on the same objective criteria: whether a Certificate of Analysis exists and is publicly available, who issued it, whether that laboratory is independent and accredited, whether heavy metals were tested to actual numeric values, and what the manufacturing and sourcing claims are.
The result is a comparable, apples-to-apples ranking across brands that vary widely in price, form, and marketing claims. Of 246+ products reviewed, only 83 (34%) have a fully public COA from a named independent laboratory — a number that reflects how opaque the shilajit industry still is.
We have no affiliation with any brand and earn no commission. Grades are assigned algorithmically from the evidence — not editorial opinion.

Shilajit has been given to people in 10 published studies, 7 of them with a comparison group — most with fewer than 65 participants. The evidence is real but narrow, and the bigger risk is what a given product is contaminated with.
Safety. The trials that reported on it found no serious adverse effects at 200–1,000 mg a day for up to 14 weeks; one case report describes high blood pressure and low potassium in a pregnant woman (Stavropoulos 2018). The practical risk is contamination: shilajit is a mineral-rich exudate, and lead, arsenic, cadmium and mercury vary from product to product. That is what these grades measure: numeric heavy-metal results on the finished product are worth 4 of the 13 points, more than any other signal.
Every study, with dose and limits: shilajit research · is shilajit safe?
None that we could find (checked 23 September 2026). NSF's listing of certified dietary supplements has no shilajit product, and none of the brands with USP Verified products sells a USP Verified shilajit.
One graded product says it is made in an "NSF certified GMP compliant facility" — that registers the factory's processes, not the product. Product certification (NSF/ANSI 173 or USP Verified) means the certifier itself tests the product against its label and for contaminants, and keeps re-auditing it. A COA is a single lab report on one batch, commissioned by the brand — which is why these grades look at what each COA actually documents. ConsumerLab publishes its results to subscribers only; we have not reviewed them.
Each product receives an overall grade from A+ to F based on what its COA documents, capped by product form.
Resin only. Verified independent COA with numeric finished-product heavy metals, named lab, microbial panel, batch code
Verified independent COA with numeric heavy metals, missing an extra such as a batch code. Resin or liquid extract
Verified COA with gaps — no heavy metal values, or issued by the manufacturer. Highest grade for powders, capsules, tablets
Unverified COA with partial evidence. Highest grade for gummies, honey sticks, blends
COA claimed but not verified
A single weak signal, such as a stated country of manufacture
No verifiable quality signal of any kind
Best Resin
Least-processed form — the only one that can grade A+
Best Tested
Public COA, named accredited lab, numeric heavy metal values
Best Value
Strong testing credentials at a competitive price per gram
Distribution of overall grades across 246 reviewed products.
The shilajit market has almost no regulatory oversight. These signals separate credible products from marketing-only brands.
Each category ranks products on the same grading criteria, filtered to the most relevant signal for that use case.
What is the best shilajit brand in 2026?
The products graded A+ in our database are resins from Pürblack and Life Cykel. Essencraft, U.S. Shilajit (liquid), Puralis and Pure Himalayan Shilajit follow at A. Only resin can reach A+, because every other form has been through extra processing. Grades come from what each product's COA documents — lab independence, numeric heavy metal results for the finished product, batch traceability — not from brand claims. We earn affiliate commission on Pürblack links; it has no effect on grades.
What does an A+ grade mean on ShilajitDB?
An A+ grade means the product is a resin with a verified Certificate of Analysis from an independent laboratory that names itself on the report, with actual numeric values for lead, mercury, arsenic, and cadmium on the finished product, plus most of: a microbial panel, a batch code, a report dated within two years, and a stated manufacturing country. Powders, capsules, and gummies cannot reach A+ however good their COA. Fewer than 5% of products reviewed reach this standard.
Which shilajit has the most fulvic acid?
Fulvic acid percentages are not comparable between brands. Fulvic acid is sold as a standalone additive, labs measure it with different methods, and some brands report it on the raw extract rather than the finished product — so a higher number proves neither authenticity nor quality. That is why fulvic acid percentage earns no points in our grading; we score heavy metal results, lab independence, and batch traceability instead.
Is Pürblack shilajit worth the price?
Pürblack's resins grade A+, with public COAs from Cambium Analytica reporting numeric heavy metal values for the finished product. They sit in the Premium rather than Ultra Premium tier because those COAs carry no batch or lot code. Whether the premium price is justified depends on how much weight you place on testing depth versus cost per gram. Disclosure: we earn affiliate commission on Pürblack links, which has no effect on its grade.
What is a Certificate of Analysis (COA) and why does it matter?
A COA is a document from a laboratory showing what was actually found in a tested sample. For shilajit, a meaningful COA shows: the lab's name and accreditation, numeric heavy metal concentrations for the finished product (not just pass/fail), and a batch code tying the report to what you bought. Without a public COA from a named lab, there is no independent verification that the product contains what it claims or that it is safe.
Which shilajit is safest for heavy metals?
Products with low measured lead in our database include Pürblack (0.121 mg/kg) and Based (0.0005 mg/serving). Every product currently graded A or A+ has a verified independent COA with numeric heavy metal values. Products without a public COA cannot be assessed for heavy metal safety at all.
