TL;DR — Quick Answer

Shilajit is a mineral-rich Ayurvedic compound containing fulvic acid and 84+ minerals. Clinical studies show 250-500mg daily increases testosterone, improves mitochondrial energy, and enhances CoQ10 effectiveness. Purified forms (PrimaVie) are best studied. Always use purified, heavy-metal-tested products.

What the Research Says

Shilajit research has accelerated in the last decade. The most significant clinical finding comes from Pandit et al. (2016, n=96, randomized double-blind placebo-controlled), which demonstrated 250mg PrimaVie shilajit twice daily for 90 days significantly increased total testosterone (+20.4%), free testosterone (+19.1%), and DHEA levels in healthy men aged 45-55. For mitochondrial function, Bhattacharyya et al. (2009) showed shilajit enhanced CoQ10 effectiveness by improving electron transport chain efficiency — making it a logical pairing with CoQ10 supplements. Safety studies by Velmurugan et al. (2012) confirmed purified shilajit at 2g/day for 45 days did not alter liver, kidney, or hematological markers. The primary safety concern remains heavy metal contamination in unpurified products.

Benefits of Shilajit

  • Testosterone support — Pandit et al. (2016, n=96, RCT) found 250mg purified shilajit (PrimaVie) daily for 90 days increased total testosterone by 20.4% and free testosterone by 19.1% in healthy men aged 45-55
  • Mitochondrial energy — Bhattacharyya et al. (2009) showed shilajit enhances mitochondrial function by improving electron transport chain efficiency and increasing CoQ10 levels in muscle tissue
  • Antioxidant activity — fulvic acid, the primary bioactive in shilajit, is a potent free radical scavenger that donates electrons to neutralize reactive oxygen species and chelates toxic metals
  • Cognitive function — a 2012 International Journal of Alzheimer's Disease review highlighted fulvic acid's ability to inhibit tau protein aggregation, a key mechanism in Alzheimer's disease
  • Exercise performance — Keller et al. (2019, n=63, RCT) found shilajit supplementation promoted skeletal muscle adaptation and reduced exercise-induced muscle damage biomarkers

Forms of Shilajit

FormBioavailabilityBest For
Purified Shilajit ResinHighTraditional form — most potent but requires careful sourcing and purification to remove heavy metals
PrimaVie (Purified Shilajit Extract)HighBest-studied standardized extract — patented purification process, used in clinical trials
Shilajit Capsules/TabletsModerateConvenient dosing — quality varies widely; look for fulvic acid standardization and heavy metal testing

Dosage Recommendations

General recommendation: 250-500mg purified shilajit daily (standardized to 50%+ fulvic acid)

Timing: Morning and/or early afternoon; some practitioners recommend dissolving resin form in warm water

Side Effects and Safety

Safety profile: Safe with Caution

Potential Side Effects

  • Generally well-tolerated in purified forms
  • Mild digestive discomfort (uncommon)
  • Unpurified/raw shilajit may contain heavy metals (lead, arsenic, mercury) — only use purified products
  • May increase uric acid levels — use caution with gout
  • May lower blood pressure — monitor if already on antihypertensives

Drug & Supplement Interactions

  • May enhance the absorption and effectiveness of CoQ10 and other nutrients due to fulvic acid's transport properties
  • Iron supplements — fulvic acid enhances iron absorption; use caution with iron overload conditions
  • Blood pressure medications — shilajit may have additive hypotensive effects
  • Diabetes medications — some evidence suggests blood sugar-lowering effects; monitor glucose levels

Frequently Asked Questions

Does shilajit really increase testosterone?

The best evidence comes from Pandit et al. (2016), a well-designed RCT of 96 men showing 250mg purified shilajit (PrimaVie) twice daily for 90 days increased total testosterone by 20.4% and free testosterone by 19.1%. An earlier pilot study (Biswas et al., 2010) showed similar increases in infertile men. Effects may be mediated through supporting Leydig cell function and reducing oxidative stress in testicular tissue.

Is shilajit safe? What about heavy metals?

Purified shilajit from reputable brands (especially PrimaVie) that undergoes third-party heavy metal testing is considered safe at 250-500mg daily based on clinical trials up to 90 days. The critical concern is unpurified or raw shilajit, which can contain dangerous levels of lead, arsenic, and mercury. Never use raw shilajit from unverified sources. Always check for a Certificate of Analysis (COA).

How does shilajit compare to other testosterone boosters?

Shilajit has stronger RCT evidence than many popular testosterone boosters. The 20% testosterone increase from Pandit et al. compares favorably to ashwagandha (~17% in Lopresti et al., 2019) and tongkat ali (~37% in Talbott et al., but smaller studies). Shilajit's advantage is its additional mitochondrial and antioxidant benefits. It pairs well with ashwagandha for a comprehensive approach.
