- A batch-specific COA from a named laboratory, covering lead, cadmium, mercury and arsenic, and microbiology.
- A label naming the responsible business, a batch number, a date mark and the shilajit amount per serving.
- No claims to treat, prevent or “boost” anything.
If a product fails any of these, move on. Price and format only matter once these are met.
Step 1: Check it suits you
Before comparing products, rule yourself in or out. There is no safety data for pregnancy, breastfeeding or under-18s, and no published interaction studies. If you take prescription medicines, have a long-term condition or compete in tested sport, get advice first. Is shilajit safe?
It also helps to be clear about what you expect. If you are buying for a specific health reason, check what the evidence actually shows for it on evidence by topic. Expecting a proven effect sets you up to overpay for marketing.
Step 2: Pick a form
| Form | Choose it if… | Avoid it if… |
|---|---|---|
| Resin | You want the fewest ingredients and will weigh your servings | You dislike strong tastes or want a fixed dose |
| Capsules | You want a precise, tasteless dose | The capsule is a blend with no stated shilajit amount |
| Powder | You mix supplements into drinks | Carriers aren’t declared |
| Gummies | Convenience matters most | You want meaningful shilajit content or less sugar |

Step 3: Check the lab report
This is the step that separates careful sellers from the rest. Ask for the COA for the batch you would receive, then check it covers metals and microbiology with numerical results. In Great Britain, food supplements must stay within legal maximum levels for lead (3.0 mg/kg), cadmium (1.0 mg/kg) and mercury (0.1 mg/kg).[1]
- Batch number matchesThe COA’s batch is the one on sale.
- Laboratory is namedWith contact details, ideally accredited for the tests reported.
- Contaminants are coveredMetals and microbiology, not just fulvic acid.
- Results are numbersWith units and detection limits, not just “pass”.
How to read one: a COA line by line. If none is published, use the request template.
Step 4: Read the label and claims
A UK label should name the responsible business,[2] and give a batch number, a date mark and the shilajit content per serving. Then read the marketing. Health claims in UK marketing must be authorised on the GB register,[3][4] so “boosts testosterone”, “detox” or “cures fatigue” tell you the seller isn’t following the rules. Origin, altitude, “pure” and “lab tested” claims need documents behind them. Claims & myths checked
Step 5: Compare cost per serving
Divide the price by the number of servings in the pack. A cheaper jar with a larger serving size can cost more per day than a pricier one. Use the calculator and compare against UK prices. Bundles and subscriptions only save money if you would finish the extra stock before its date mark; see subscriptions and multi-buys.
Scoring sheet for comparing products
Score each product 0, 1 or 2 on each line. A product scoring 0 on any of the first three lines fails the minimum standard, whatever its total.
| Criterion | 0 | 1 | 2 |
|---|---|---|---|
| Batch COA | None | Generic or old | Matches your batch |
| Contaminant panel | Missing | Partial or “pass” only | Metals and microbiology with numbers |
| Claims | Disease or “boost” claims | Vague wellness language | Factual and restrained |
| Label | Business or batch missing | Shilajit amount unclear | Complete |
| Origin documentation | None | Region named only | Region, supplier and batch link |
| Cost per serving | Well above comparable products | Average | Below average with full documentation |
The same criteria, in more depth, are on the brand transparency checklist.
An evaluated example
If published laboratory documentation is your priority, one product that meets several of the criteria above is Nature Elixirs’ Himalayan Shilajit Resin. The brand publishes its reports, including an AGROLAB LUFA report for batch SJ2509.[5] We bought a jar ourselves and confirmed it came from that tested batch.
Evaluated example
Nature Elixirs Pure Himalayan Shilajit Resin
- Why it appears here
- Scores well on steps 3 and 4: a batch-numbered report from an ISO/IEC 17025-accredited laboratory covering metals, mycotoxins, pesticides and microbiology, with a second laboratory report and documented Himalayan origin.
- Purchase test
- Delivered by Royal Mail; the jar carried batch SJ2509, so identity and authenticity are verified.
- Suggested next step
- Inorganic arsenic speciation, as the laboratory notes, and a current-batch composition report.
- Partner brand
- Nature Elixirs is a commercial partner of Best Shilajit UK.
Apply the same five steps and the scoring sheet to any other product. A product with stronger documentation would rank above this example on the same criteria.
Where to buy, and what to do when it arrives
Brand websites usually make documents easiest to find; marketplaces add the risk of third-party sellers and mixed stock. See where to buy in the UK and buying on marketplaces. When the jar arrives, check the seal, batch number and date mark against the COA: checking your delivery.
Common questions
What is the most important thing to check?
A batch-specific lab report covering contaminants. Everything else is secondary.
Is expensive shilajit better?
Not necessarily. Price often reflects branding. Judge on documentation first, then cost per serving.
What should a first-time buyer get?
A small quantity of a well-documented product in a form you will actually use. See best shilajit for beginners.
