Shilajit Research: Every Study, Sorted by Strength of Evidence
Every paper cited anywhere on ShilajitDB, grouped by what kind of evidence it is. Each summary was written from the paper itself, not from other articles about it, and says what the study does not show as well as what it found. Where one of our articles makes a claim we could not check against the paper, the entry says so. How we check our own citations, and what we got wrong, is in the audit write-up.

human studies, no control group
For the human trials in depth — design, dose and how much weight each can bear — read the clinical trials, explained.
Last reviewed September 2026
Human trial, controlled (7)
People given shilajit and compared against a group that was not — the only design here that can separate an effect of shilajit from time, expectation and chance. Most are small.
Pandit et al. 2016·AndrologiaHuman trial, controlled
- Studied
- Healthy men aged 45–55
- Design
- Randomised, double-blind, placebo-controlled
- Dose
- 250 mg twice daily
- Duration
- 90 days
Found: Total testosterone, free testosterone and DHEAS rose significantly compared with placebo (P < 0.05); LH and FSH stayed where they were.
Doesn't show: The abstract gives no sample size and no effect sizes.
Not yet verified: Articles used to give n=96 and rises of +20.45% total / +19.22% free testosterone. Neither figure appears in the abstract (re-checked 2026-10-15) and the full text is paywalled, so the site no longer states them.

Keller et al. 2019·J Int Soc Sports NutrHuman trial, controlled
- Studied
- 63 recreationally active men, 21 per group
- Design
- Randomised, double-blind, placebo-controlled
- Dose
- 250 or 500 mg/day
- Duration
- 8 weeks
- Product
- PrimaVie
Found: At 500 mg/day, men lost less strength across a fatiguing leg-extension protocol (8.9% decline vs 16.0% on placebo) and had lower baseline serum hydroxyproline (1.5 vs 2.4 µg/mL).
Funding: Funded by Natreon Inc., which makes the PrimaVie extract tested. The authors declare no competing interests.
Doesn't show: Both results held only in the upper half of the sample by baseline strength and hydroxyproline — not in the groups as a whole. 250 mg/day did no better than placebo. Hydroxyproline went down, not up.

- Studied
- 60 elderly patients with hypertension
- Design
- Randomised, open-label, no placebo
- Dose
- 500 mg twice daily, on top of antihypertensives
- Duration
- 30 days
Found: Oxidative-stress markers improved against controls (MDA and oxidised LDL down; total antioxidant capacity, SOD and glutathione up). No change in arterial stiffness or endothelial function.
Doesn't show: Open-label: controls took their medication alone, with no placebo. It measured no blood-pressure benefit, and the vascular outcomes did not move. Not indexed in PubMed.

- Studied
- 35 recreationally trained men
- Design

- Duration
- 8 weeks
Found: Serum pro-c1α1, a marker of type 1 collagen synthesis, rose from about 42 to 82 ng/mL (500 mg) and 113 ng/mL (1,000 mg); placebo did not change.
Doesn't show: A blood biomarker, not tendon, skin or joint outcomes. The share of people clearing the clinically important threshold beat placebo only at 1,000 mg (75% vs 30%); at 500 mg the difference was not significant.

Martinez et al. 2025·NutrientsHuman trial, controlled
- Studied
- 166 sedentary adults with metabolic syndrome risk factors (109 completed), on diet and exercise
- Design
- Randomised, double-blind, placebo-controlled
- Dose
- 6 or 12 mg shilajit, with chromium and Phyllanthus emblica
- Duration
- 12 weeks
Found: Some evidence (p < 0.05 or approaching it) of better vascular function, platelet aggregation, insulin sensitivity and lipids than placebo, more consistently at 6 weeks than 12.
Doesn't show: A three-ingredient combination at roughly one-fortieth of the shilajit dose used in other trials. It cannot separate any effect of shilajit from chromium or P. emblica — one arm got P. emblica alone.

Human study, no control group (3)
People given shilajit and compared with themselves before and after. These show what changed, not what shilajit caused.
Biswas et al. 2010·AndrologiaHuman study, no control group
- Studied
- 60 infertile men assessed, 35 oligospermic enrolled, 28 completed
- Design
- Open-label, single arm, no placebo

Narrative review (7)
Summaries of other people's work. They generate no data of their own, and they are only as good as the studies they summarise.
Stohs 2014·Phytother ResNarrative review
Found: Concludes that shilajit's safety is well documented in animal and human studies, that relatively few well-controlled human studies exist, and that dibenzo-α-pyrones and fulvic acid appear to be the key constituents.
Doesn't show: A narrative review that generates no data of its own, and predates every human trial after 2014.
Not yet verified: The "100–2,000 mg/day" range some of our articles attribute to it is not in the abstract.

Wilson et al. 2011·J EthnopharmacolNarrative review
Found: Shilajit appears in 20 classical formulations and 24 proprietary drugs, but "lacks scientific evaluation": its antioxidant activity was tested at an irrelevant dose without a positive control, and its immunomodulatory activity "may be considered as unproven".
Doesn't show: The most sceptical review of the set — worth reading next to Stohs 2014.

Hussain et al. 2024·Biol Trace Elem ResNarrative review
Found: Across published analyses, shilajit contains around 65 metals including Pb, As, Cd and Hg. Most reported levels were within WHO/FDA limits for herbal drugs, but some studies found them exceeded; the authors conclude that taking shilajit without knowing its metal levels is not safe.
Doesn't show: Claims that humic substances detoxify metals are, in the authors' words, still to be clarified.

Composition analysis (3)
Laboratory analysis of what shilajit samples actually contain.
Janković et al. 2026·MoleculesComposition analysis
- Studied
- Two shilajit resin samples used as raw material
Found: Urolithin A was highest in methanol/ethyl acetate extracts. The sample with 2.504 ppm urolithin A gave 90% (gold) and 96% (selenium) nanoparticle yields against 15% and 34% for the sample with 0.002 ppm. Selenium nanoparticles inhibited several bacteria and fungi at 0.125–1 mg/mL, gold nanoparticles at 0.25–5 mg/mL.
Funding: Pürblack Inc. paid the article fee (grant 1021-PUR/X-2026) and supplied the samples. One author is the founder and CEO of Pürblack Inc., holds shilajit patents, and declares it.
Doesn't show: A materials-chemistry study that uses shilajit as a raw material. The antimicrobial tests were on the nanoparticles, not on shilajit, so it says nothing about taking shilajit. Two samples only.
Rizun et al. 2026·npj Sci FoodComposition analysis
- Studied
- Ten resins the authors prepared from shilajit rock of five mountain regions
Found: Potassium was the dominant element (36,291–95,579 ppm). Arsenic was 0.14–1.34 ppm, cadmium 0.01–0.10 ppm and lead 0.35–3.01 ppm; mercury was not detected. Urolithin A was 0.07–1.63 ppm in a methanol extract and 3.5–58.5 ppm in a methanol/ethyl acetate extract (urolithin B was never detected), highest in three blends made from Andean, Sierra Madre and Carpathian rock. In a lab dish the resins only weakly inhibited a few bacteria and fungi (MIC 3.12–25 mg/mL) and did nothing to E. coli, P. mirabilis or K. pneumoniae.
Funding: Pürblack Inc. paid the article fee (grant 1021-PUR/X-2026) and supplied the samples. The first author is the founder and CEO of Pürblack Inc., which sells shilajit resin, and holds shilajit patents; both are declared. The paper says samples were coded and analysed blind, with the elemental and urolithin A measurements run in outside laboratories.
Doesn't show: Ten lab-prepared resins, not retail jars, so it says nothing about any product you can buy. No human, animal or cell outcome was measured; calling urolithin A shilajit's most promising bioactive is the authors' framing, not a result. Their urolithin A values are at least 5-fold below the 300–4,200 ppm they cite from another analysis, and the number depends heavily on the extraction solvent. At the paper's own 0.5 g/day assumption, 5 of the 10 samples supply more than the 0.5 µg/day of lead that the paper itself cites as California's Proposition 65 figure; the paper compares lead to a WHO weekly figure instead. This is the early-access version and may change.

- Studied
- Rats, forced-swim model of chronic fatigue
- Dose
- 25, 50 or 100 mg/kg
- Duration

Found: Shilajit reversed fatigue-like behaviour, restored corticosterone and adrenal weight, and preserved mitochondrial enzyme activity and membrane potential in the prefrontal cortex.
Doesn't show: A rat study. Several of our articles once presented it as a human double-blind trial; no human trial of shilajit for chronic fatigue exists.

Mishra et al. 2018·AndrologiaAnimal study
- Studied
- Adult male Swiss mice made infertile with cadmium
- Dose
- 50, 100 or 200 mg/kg
- Duration
- 35 days (one mouse spermatogenic cycle)
Found: Shilajit raised testicular sperm production, serum testosterone and testicular enzyme activity, restored germ-cell layers in the testis, and reversed cadmium's effect on sperm motility and concentration. Fertility and litter numbers also improved, more at higher doses.
Doesn't show: A mouse study in which infertility was induced with cadmium, so it says nothing about men whose low sperm counts have other causes. Doses are per kilogram of body weight and do not convert to a human dose.

Rizun et al. 2026·Pharmaceuticals (Basel)Animal study
- Studied
- Male Wistar rats given ten shilajit samples
- Dose
- One oral dose of 2,000 mg/kg
- Duration
- 14 days of observation
Found: No deaths, clinical signs of toxicity or notable changes in food, water or weight (LD50 above 2,000 mg/kg). Serum testosterone and lipid profiles changed; in a follow-up of the two samples with the highest free testosterone, total and free testosterone were about 2.5-fold and 3.5-fold higher than controls. Those two samples were also the richest in urolithin A and phenolic acids.
Funding: Pürblack Inc. paid the article fee (grant 1021-PUR/X-2026) and supplied the samples. The first author is the founder and CEO of Pürblack Inc., which sells shilajit resin, and declares it.
Doesn't show: A single-dose rat study. The testosterone follow-up was exploratory and limited to the two samples that had already shown the highest free testosterone. The authors report mild to moderate degenerative and necrotic changes in liver and kidney tissue, and say the findings do not exclude tissue effects or show they reverse. No human has been studied here.
