Ayurveda classified shilajit as a vrishya, a substance that supports male reproductive health and vitality thousands of years before testosterone was identified as a hormone. Modern clinical research has now confirmed precisely why. Here is what the science shows.

What ayurveda knew and what science has now confirmed

Long before testosterone was identified as a hormone, Ayurvedic texts classified shilajit as a vrishya, a substance that builds male reproductive strength, supports vitality, and promotes physical power and endurance. The Charaka Samhita described it as capable of transforming an aging man into one of youthful vigour when used consistently as a rasayana. These were not metaphorical claims. They were clinical observations, accumulated over centuries of practice, that modern research is now explaining at the molecular level.

The most clinically significant of all shilajit benefits for men is its support for healthy testosterone levels and the evidence base behind this application is more substantiated than almost any other natural compound in the male health supplement space.

What the research actually shows

The key clinical trial. The most cited peer-reviewed study on shilajit and testosterone is a double-blind, placebo-controlled trial published in the journal Andrologia. The study followed healthy male volunteers supplementing with purified shilajit over 90 days. Results showed statistically significant increases in total testosterone, free testosterone, and DHEA-S compared to the placebo group. The improvement in free testosterone the biologically active, unbound fraction that reaches tissues and drives the physiological effects men are actually seeking was particularly meaningful.

Total vs free testosterone why the distinction matters for Indian men. Total testosterone measures the overall quantity in the bloodstream, but a significant proportion is bound to proteins particularly sex hormone-binding globulin (SHBG) and is therefore biologically unavailable. Free testosterone is the unbound, active fraction. The research on pure shilajit has documented improvements in both meaning the benefits translate from a blood test number to actual tissue-level hormonal activity that influences energy, strength, mood, and libido.

DHEA-S the underappreciated hormonal finding. DHEA-S (dehydroepiandrosterone sulphate) is an adrenal precursor hormone that declines with age and serves as a building block for testosterone and other steroid hormones. Healthy DHEA-S is associated with preserved muscle mass, emotional resilience, cognitive function, and sustained vitality qualities that Ayurveda associated with ojas, the vital essence that shilajit was said to protect and replenish. The research on shilajit has documented meaningful improvements in DHEA-S extending its hormonal support well beyond testosterone alone.

The mechanisms: how shilajit supports testosterone

Cortisol and testosterone are the inverse relationship. Cortisol and testosterone share a well-documented hormonal competition. Both require the same precursor compound pregnenolone and when the body's stress response is chronically activated, cortisol synthesis takes priority at the expense of testosterone production. For Indian men navigating the chronic stress of competitive careers, financial pressures, and demanding urban lifestyles, this cortisol-driven testosterone suppression is one of the most practically relevant and underaddressed factors in declining male hormonal health.

Shilajit's fulvic acid and adaptogenic mineral profile support adrenal function and the body's overall stress response indirectly but meaningfully supporting testosterone by reducing the cortisol-mediated hormonal competition that suppresses it.

Luteinising hormone support. Luteinising hormone (LH) is the pituitary signal that directly instructs Leydig cells in the testes to produce testosterone. Research suggests that shilajit supplementation supports healthy LH levels preserving the upstream endocrine signal that drives testosterone synthesis. This is a physiologically coherent mechanism that works at the hypothalamic-pituitary level, making shilajit's testosterone support a genuine contribution to the hormonal axis rather than a surface-level effect.

Mitochondrial support for testosterone biosynthesis. Leydig cells, the testosterone-producing cells in the testes, are energetically demanding. They rely on efficient mitochondrial ATP production to sustain the steroid hormone biosynthesis process. Fulvic acid's well-documented role in supporting mitochondrial energy production including its enhancement of CoQ10 activity provides a cellular foundation for Leydig cell function that contributes to testosterone support from the ground up.

Antioxidant protection of testicular tissue. Oxidative stress in testicular tissue is associated with impaired testosterone production and reduced sperm quality. Fulvic acid's broad-spectrum antioxidant properties and its ability to neutralise a wide range of free radicals provide meaningful protection against this oxidative damage. This is a particularly significant mechanism for Indian men whose oxidative stress burden is elevated by urban air pollution, processed food consumption, and chronic psychological stress.

Shilajit and male fertility

The vrishya classification of shilajit in Ayurveda extended specifically to reproductive health and modern research validates this application directly. Clinical studies have documented improvements in sperm count, sperm motility, and sperm morphology with consistent shilajit supplementation. These outcomes are consistent with the antioxidant protection of testicular tissue and the broader hormonal support effects described above and are directly relevant to Indian men navigating fertility concerns, which are increasingly prevalent in the context of urban lifestyle factors and environmental exposures.

Shilajit and ashwagandha India's most powerful combination for male hormonal health

Two of Ayurveda's most revered vrishya herbs used together create the most comprehensive natural approach to male hormonal health available. Ashwagandha supports testosterone by reducing cortisol and supporting LH levels through its HPA axis-modulating adaptogenic mechanism. Shilajit contributes through mitochondrial energy support, antioxidant protection, and the mineral nutrition that underpins testicular function. Together they address testosterone support from multiple complementary angles, a combination with both deep Ayurvedic roots and an increasingly compelling modern evidence base.

Putting the evidence in context

Shilajit supports the body's own testosterone production within a physiological range; it is not a pharmaceutical hormone replacement and does not produce artificially elevated testosterone. What it does is address several of the most common upstream drivers of testosterone decline chronic cortisol elevation, suboptimal LH signalling, mitochondrial insufficiency, and oxidative stress in testicular tissue in a way that is physiologically grounded, well-tolerated, and validated by peer-reviewed research.

At BetterAlt, our shilajit resin is the purified, independently laboratory-tested Himalayan shilajit that clinical testosterone research is based on, verified for fulvic acid content, FSSAI-compliant, and tested for heavy metal safety on every batch. This is the standard that makes the research reproducible in real-world use.

Conclusion

The research on shilajit and testosterone represents one of the strongest evidence bases in natural men's health supplementation. Clinical studies document meaningful improvements in total testosterone, free testosterone, DHEA-S, and sperm quality through mechanisms that are coherent, well-understood, and deeply aligned with Ayurveda's thousand-year understanding of shilajit as a vrishya. Choose pure shilajit from a verified, lab-tested Himalayan source, use it consistently, and give the hormonal mechanisms the time they need to work.
