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) — 96 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 (+20.45%), free testosterone (+19.22%), and DHEAS. No adverse effects were reported. PubMed 26395129.
• Biswas et al. (2010) — 60 infertile men received processed shilajit for 90 days. Significant improvements were observed in total sperm count (+61.4%), sperm motility (+12.4–17.4%), and testosterone levels. PubMed 25575901.

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 increased serum hydroxyproline levels, suggesting a role in connective tissue recovery. PubMed 30870558. Whether this effect is specific to men is unknown — women were not enrolled.

For Women: Iron, Energy, and Hormonal Context

Iron bioavailability

The most well-supported benefit of shilajit specifically relevant to women is its effect on iron absorption. Fulvic acid chelates non-haem iron and maintains it in the ferrous (Fe²⁺) form, which is significantly more bioavailable than ferric (Fe³⁺) iron. This is relevant for premenopausal women, who have higher iron requirements due to menstrual losses, and for women following plant-based diets.

A study in women with iron deficiency anaemia found significant improvements in haemoglobin, red blood cell count, and haematocrit after 12 weeks of shilajit supplementation. Trivedi NA et al., J Ethnopharmacol 2011.

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 the heavy 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:

• Fatigue reduction and mitochondrial support (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
