Carlyle Shilajit Capsules Review

The Supplement Facts panel states it directly: each capsule contains 400 mg of Shilajit Extract (Asphaltum), a 5:1 extract standardized to 'equivalent to 2,000 mg of Shilajit,' with one capsule per serving and 90 servings per container. That matches the front-of-label claim ('Shilajit 2,000 MG equivalent') and Carlyle's own site listing (product handle shilajit-2000mg-90-capsules, listed at $10.59). What the label doesn't give you is a fulvic-acid percentage, so you can't characterize the extract's potency beyond the stated dose — and an 'equivalent' extract claim isn't the same as the purified, standardized dose used in the human trials (500 mg/day). If matching the clinical dose precisely matters to you, that's the real limitation here, not a missing number.

No published panel, and the weakest testing language in our lineup. The listing offers only an in-house 'laboratory tested' claim with a 100% guarantee — not a third-party seal, not a badge, and certainly not a published heavy-metal panel with numbers for lead, arsenic, mercury, cadmium, or thallium. That's a real concern in this category: a 2025 BMC Chemistry study (PMID 39827344) found thallium up to ~0.5 µg/g in commercial shilajit, sometimes above the raw rock, so external testing matters most for the cheapest products. An in-house claim is the lowest tier of reassurance here — several pricier picks at least cite third-party testing. If you buy this, treat the in-house claim with appropriate skepticism and ask for a current third-party COA.

The listing states the shilajit extract is sourced from mineral-rich resin along the Indian Himalayas, which is a legitimate, named origin — a point in its favor over a vague 'high-altitude' claim. Carlyle is an established value brand, and the listing notes the product is non-GMO and free of gluten, wheat, yeast, lactose, soy, artificial flavors, and preservatives. So the sourcing claim itself is reasonable. The weaknesses aren't about where it comes from — they're about what the label won't tell you: a fulvic-acid percentage and any third-party testing results.

Only with eyes open, and arguably not as your real shilajit. At about $11 for 90 capsules it's by far the cheapest pick, which is a legitimate reason to use it as a bare-bones trial. But 'cheapest' is doing a lot of work here: the label discloses the dose, but there's no fulvic-acid percentage and the only testing claim is in-house. In a category where the invisible risk is heavy metals, a cheap jar backed only by in-house testing is one to approach with some caution. If you want a cheap capsule you can actually trust, Double Wood (#1) is only a few dollars more, discloses 20% fulvic acid, states its exact mg, and cites a third-party testing program — a better-disclosed budget choice.

[1] Pandit 2016 PMID 26395129 — Clinical evaluation of purified Shilajit on testosterone levels in healthy volunteers. ~75 men, 90 days: purified shilajit 500 mg/day raised total and free testosterone and DHEAS. The dose you'd want to target — but Carlyle's label states an 'equivalent to 2,000 mg' extract-ratio claim rather than a purified, trial-matched mg, so precise comparability to this study's dose isn't straightforward.
2. [2] Stohs 2014 PMID 23733436 — Safety and efficacy of shilajit (mumie, moomiyo). Review concluding purified shilajit is safe in clinical use, with purification as the precondition. Underlines why an in-house testing claim on the cheapest product is the weakest reassurance in the lineup.
3. [3] Kamgar 2025 PMID 39827344 — Quantifying of thallium in Shilajit and its supplements to unveil the potential risk of consumption of this popular traditional medicine. Thallium up to ~0.5 µg/g in commercial shilajit, sometimes above the raw source. Why the cheapest product with only an in-house testing claim warrants the most caution — external verification matters most here.
