Shilajit for Men and Women: Are the Effects Different?

Shilajit's traditional use has historically been associated with male vitality — the Sanskrit term shilajit translates roughly to "conqueror of mountains and destroyer of weakness" and its Ayurvedic applications were often framed around male reproductive health. But the research picture is more nuanced: shilajit contains compounds with different relevance for men and women, and several mechanisms are sex-specific.

For Men: Testosterone and Reproductive Health

What the research shows

The strongest clinical evidence for shilajit centres on male hormonal health. Two well-designed randomised controlled trials have examined this:

• Pandit et al. (2016) — healthy men aged 45–55 received purified shilajit (250 mg twice daily) or placebo for 90 days. The shilajit group showed statistically significant increases in total testosterone, free testosterone and DHEAS. The abstract does not give the sample size or the size of the rises (see Does Shilajit Boost Testosterone?). PubMed 26395129.
• Biswas et al. (2010) — 60 infertile men were assessed, 35 enrolled and 28 completed 90 days of processed shilajit. Improvements against their own baselines were seen in total sperm count (+61.4%), sperm motility (+12.4–17.4%) and testosterone (+23.5%). The study was open-label with no placebo group. PubMed 20078516.

Proposed mechanisms

The testosterone-raising mechanism of shilajit is not fully elucidated, but several pathways have been proposed:

• Stimulation of luteinising hormone (LH) secretion from the pituitary, which signals Leydig cells in the testes to increase testosterone production
• Reduction of oxidative stress in testicular tissue — mitochondrial antioxidant effects may protect Leydig cell function
• Zinc and selenium content — both minerals are cofactors for testosterone synthesis and are often found in ionic form in shilajit

Physical performance and muscle recovery

A study by Keller et al. (2019) enrolled healthy active men and found that 500 mg/day of shilajit for 8 weeks attenuated the decline in maximum strength during a fatiguing exercise protocol and lowered baseline serum hydroxyproline, suggesting a role in connective tissue turnover. Both effects held only within the stronger half of the 63-man sample, and neither appeared at 250 mg/day. PubMed 30728074. Whether this effect is specific to men is unknown — women were not enrolled.

For Women: Iron, Energy, and Hormonal Context

Iron bioavailability

The benefit most often claimed for women is iron absorption, and it rests on chemistry rather than on trials. Fulvic acid is a metal chelator, and chelated non-haem iron held in the ferrous (Fe²⁺) form is more bioavailable than ferric (Fe³⁺) iron — which matters in principle for premenopausal women, who have higher iron requirements from menstrual losses, and for women following plant-based diets.

The mechanism is supported by what analysis shows: a 2026 ICP-MS study of twelve shilajit samples found most metals, iron included, bound in low-molecular-weight complexes consistent with humic acid rather than present as free ions. Kamgar E et al., J Trace Elem Med Biol 2026.

Adaptogenic effects and stress response

Shilajit is classified as an adaptogen in Ayurvedic medicine — a substance that helps the body maintain homeostasis under stress. The fulvic acid and DBP content may support cortisol regulation and adrenal function, effects that are relevant regardless of sex. Women dealing with fatigue related to HPA axis dysregulation may benefit from the same mitochondrial support documented in the general fatigue literature.

Menopause and hormonal transition

There is no published RCT examining shilajit's effects in perimenopausal or postmenopausal women. Some practitioners in integrative medicine have used shilajit in this context based on its mineral content (magnesium, zinc) and adaptogenic properties, but clinical evidence is absent. This is an area where anecdotal use outpaces research.

Safety Considerations by Sex

Pregnancy and breastfeeding

No safety data exists for shilajit use during pregnancy or breastfeeding. Given theheavy metal risks associated with unverified shilajit products, and the absence of safety studies in this population, shilajit is not recommended during pregnancy or breastfeeding. Even verified, high-quality products carry an uncertain risk profile in this context.

Hormonal conditions

Women with hormonal conditions — PCOS, endometriosis, oestrogen-sensitive conditions — should consult an endocrinologist or gynaecologist before using shilajit. While no specific adverse interactions have been documented, the adaptogenic and mineralogenic effects of shilajit have not been studied in these contexts.

Iron overload

Because shilajit improves iron absorption, individuals with haemochromatosis (hereditary iron overload) or elevated serum ferritin should use caution. Enhancing iron absorption in this context could worsen an existing condition.

Shared Benefits: What Applies to Both

Several researched effects are not sex-specific:

• Reduced fatigue-induced strength loss in men (Keller et al. 2019); the wider mitochondrial fatigue evidence is from rats (Surapaneni et al. 2012)
• Anti-inflammatory and antioxidant effects (in-vitro evidence)
• Altitude sickness relief (traditional use; limited clinical data)
• Cognitive support (in-vitro and animal models; human trials pending)
• Mineral supplementation via ionic mineral complex
