Shilajit Benefits for Men: What the Research Actually Shows

Shilajit is sold to men more than to anyone else, usually with big promises. Some of those promises have research behind them; most don't. This guide sticks to what has actually been measured in humans, so you can decide with realistic expectations.

First, a legal note you should welcome

In the UK, a food supplement cannot legally claim to treat, prevent or cure any condition, or to "boost testosterone". A seller who says those things in plain words is either breaking the rules or doesn't know them – neither is a good sign. What we can do is describe the research honestly.

What human studies have looked at

Testosterone

The most cited study is a 90-day randomised, placebo-controlled trial in healthy men aged 45–55 taking 250 mg of purified shilajit twice daily. The shilajit group showed higher total and free testosterone than placebo at the end of the study. It is one trial, with 75 participants, funded by a shilajit manufacturer, and it hasn't been repeated at scale. That makes it interesting, not conclusive. Men with clinically low testosterone should see a doctor, not a supplement.

Sperm quality

A 90-day study of 60 men with low sperm counts taking 100 mg of purified shilajit twice daily reported increases in sperm count and motility. Again: one study, small, not placebo-controlled. Promising; not proof.

Energy and fatigue

Shilajit's fulvic acid and mineral content is often linked to "energy" claims. The human evidence is thin: a small study suggested shilajit may help maintain muscle strength under fatigue after exercise, and lab work points to effects on mitochondrial function. Most of what you read about energy comes from traditional use and user reports rather than trials.

Exercise and recovery

An 8-week study in recreationally active men taking 500 mg per day found better retention of maximal strength after a fatiguing protocol compared with placebo. Small, single study, but relevant if you train.

Bone and general health

Some research in postmenopausal women suggests effects on bone markers; this isn't men-specific but shows shilajit is being studied beyond the "male vitality" angle.

What hasn't been shown

• No study shows shilajit treats erectile dysfunction.
• No study shows it builds muscle on its own.
• No study shows it reverses ageing, hair loss or anything of the kind.
• No study has compared resin, capsules and gummies head-to-head.

If a site tells you otherwise, ask for the study.

What this means in practice

If you're a healthy man curious about shilajit, the reasonable position is: it is a traditional mineral-rich supplement with a small amount of encouraging early research in men, it is well tolerated at normal doses, and it is cheap enough to try for three months and judge for yourself. Keep your expectations modest and your product purified.

How men typically take it

• Amount: a pea-sized serving of resin (about 250–300 mg) once a day – the same range used in the studies above. Capsules: 2 a day.
• Timing: morning, or 30–60 minutes before training.
• Duration: give it 8–12 weeks before judging; the trials ran 60–90 days.
• Breaks: a few weeks off after each cycle.

The one thing that matters more than the form

Every study above used purified shilajit. Raw or untested product can carry heavy metals, and that is the real risk with this supplement. Only buy from a seller who publishes a batch-specific certificate of analysis – ours are on the Lab Reports page.
