Shilajit Benefits for Men: Testosterone, Energy & What Research Shows (2026)

Updated: April 2026

Short answer: Shilajit is a mineral-rich resin containing fulvic acid that may support testosterone levels, mitochondrial energy production, and physical performance. A 90-day placebo-controlled trial showed a roughly 20% increase in total testosterone in men aged 45–55. However, product quality varies enormously — ConsumerLab found fulvic acid content differing by 32,000% across tested supplements. Only purified, third-party tested shilajit is considered safe for daily use.

Shilajit is a tar-like substance formed over centuries from decomposed plant matter trapped between layers of Himalayan rock. It has been used in Ayurvedic medicine for over 3,000 years as a rejuvenating tonic — and in the last decade, a small but growing body of human clinical research has started putting those traditional claims to the test.

This guide covers what the published evidence actually shows, where the science is still thin, and why the supplement you choose matters as much as whether you take it.

What Is Shilajit?

Shilajit is a naturally occurring organic-mineral complex formed over centuries as plant matter decomposes under geological pressure in high-altitude mountain environments — primarily the Himalayas, Altai, Caucasus, and Karakoram ranges. The end product is a dark, resinous substance containing over 80 minerals in ionic form, plus fulvic acid (typically 40–70% of purified extracts) and dibenzo-alpha-pyrones (DBPs).

Fulvic acid is the bioactive compound that gets the most research attention. It acts as a natural chelator — binding to minerals and enhancing their transport across cell membranes. It also supports electron transfer within mitochondria, which is why researchers describe shilajit as a "mitochondrial booster" rather than a simple mineral supplement.

DBPs serve a complementary role: they protect CoQ10 from oxidation and act as electron carriers in the mitochondrial energy chain. According to research published in Life Extension Magazine, the combination of fulvic acid and DBPs creates a synergistic effect on cellular energy metabolism that neither compound produces alone.

Testosterone: What the Clinical Trials Show

According to Pandit et al. (2016, Andrologia), purified shilajit at 250 mg twice daily for 90 days significantly increased total testosterone, free testosterone, and DHEAS compared with placebo in healthy men aged 45–55. Gonadotropic hormones (LH and FSH) remained stable, suggesting the effect operates downstream of the pituitary axis.

A 2024 clinical evaluation by Mehra et al. using 500 mg/day of MEET Shilajeet® (a branded extract standardized for fulvic acid) over 90 days confirmed statistically significant increases in both total and free testosterone, along with improvements in vitality and wellbeing scores. No serious adverse events were reported.

These are real findings from real trials. But context matters: both studies had relatively small sample sizes, both used specific purified extracts, and neither lasted longer than 90 days. The testosterone increase — roughly 20% — is meaningful but modest compared to pharmaceutical interventions. If you're expecting shilajit to function like testosterone replacement therapy, it won't. What it may do is support healthy testosterone levels that have declined with age.

Energy and Mitochondrial Function

The energy-related benefits of shilajit trace back to fulvic acid's effect on mitochondria — specifically, its ability to enhance electron transport chain efficiency and increase CoQ10 levels in muscle tissue.

A 2012 study published in the Journal of Ethnopharmacology demonstrated that shilajit supplementation significantly increased ATP levels and CoQ10 concentrations in muscle tissue. This isn't the kind of energy you feel from caffeine — it's the kind that shows up as less fatigue at the end of the day, faster recovery between workouts, and better sustained performance under physical stress.

If you're already exploring other energy-supporting supplements like mushroom coffee or NMN for NAD+ restoration, shilajit works through a different mechanism: while NMN restores NAD+ levels directly, shilajit enhances mitochondrial efficiency through CoQ10 protection and electron transfer. They address different bottlenecks in the same energy production chain.

Physical Performance

According to Keller et al. (2019, JISSN), 500 mg/day of shilajit for 8 weeks improved maximal muscular strength on bench press and leg press compared to placebo in recreationally active men. Researchers also observed reduced markers of exercise-induced muscle damage.

Das et al. (2016, Journal of Medicinal Food) found that shilajit supplementation upregulated genes involved in extracellular matrix remodeling and muscle repair — without increasing creatine kinase or myoglobin, suggesting recovery improvements without additional tissue stress. If you're also looking into creatine for physical performance, shilajit operates through a completely different pathway — connective tissue support and mitochondrial efficiency rather than phosphocreatine loading.

A 2025 open-label pilot study (28 days of resin supplementation) reported favorable changes in body composition and inflammatory markers, though the study design — single-arm, no placebo control — limits the strength of these conclusions.

Male Fertility

According to Pandit et al. (2010, Andrologia), purified shilajit at 200 mg/day for 90 days improved sperm count, sperm motility, and total testosterone in men with low sperm count. The improvements were statistically significant.

This is a single study with a specific clinical population — men with diagnosed fertility challenges, not the general population. Still, the combination of testosterone support and direct sperm quality improvement makes shilajit one of the more interesting natural compounds for male reproductive health. If you're looking at adaptogens for male health more broadly, ashwagandha (KSM-66) has its own evidence base for sperm quality through a different mechanism (cortisol reduction).

The Quality Problem: Why Your Product Choice Matters More Than You Think

Here's where shilajit gets complicated — and where most marketing falls apart. ConsumerLab independently tested eight commercial shilajit products in 2024 and found that fulvic acid content varied from 6.9 mg to 2,206 mg per serving. That's a nearly 32,000% difference between the lowest and highest.

To put that in perspective: if the clinical trials used products with 60–70% fulvic acid, and the supplement you bought contains 3% fulvic acid, you're not taking the same thing. You're paying for a label, not a clinical effect.

The heavy metal issue is equally important. Raw shilajit naturally contains around 65 heavy metals, including lead, arsenic, cadmium, and mercury (Hussain & Saeed, 2024, Biological Trace Element Research). Purification removes these to safe levels — but only if the manufacturer actually tests for them. The FDA has specifically flagged potential heavy metal accumulation in shilajit supplements.

What to look for: third-party lab testing (ideally ICP-MS for heavy metals), a published Certificate of Analysis (COA), standardized fulvic acid content, and GMP-certified manufacturing. If a brand can't show you their test results, that alone is a red flag. For our approach to testing standards, see our third-party lab results and ingredient sourcing page.

Who Should Be Cautious

Shilajit is generally well tolerated in clinical trials at doses of 200–500 mg/day for up to 90 days. But it's not appropriate for everyone.

If you take blood pressure or blood sugar medication, separate shilajit intake by at least 2 hours — fulvic acid enhances mineral absorption and may affect drug bioavailability. If you have gout or elevated uric acid, shilajit's mineral density could theoretically worsen symptoms. Pregnant or nursing women should avoid shilajit entirely — there is no human safety data for these populations.

And the uncomfortable truth most brands won't say: if you're under 35, sleeping well, eating properly, exercising consistently, and have no symptoms of low testosterone, shilajit is unlikely to produce noticeable results. The clinical benefits have been demonstrated primarily in men over 45 with age-related hormonal decline.

Shilajit Dosage: What the Trials Used

Most clinical trials testing testosterone and physical performance outcomes used 250–500 mg/day of purified, standardized shilajit extract for 8–12 weeks.

250 mg twice daily (500 mg/day) — Used in the Pandit 2016 testosterone trial and the Keller 2019 strength study. This is the most commonly tested dose.

200 mg/day — Used in the 2010 fertility study. Effective for sperm parameters but may be subtherapeutic for testosterone effects.

300–500 mg/day — The general range recommended by most researchers for adaptogenic and mitochondrial support. Take with breakfast or lunch — some users report mild stimulation that can interfere with sleep if taken in the evening.
