Shilajit: What It Actually Does, According to Science

Walk into any chemist in India or scroll Instagram for five minutes and you'll see shilajit sold as the answer to everything: energy, stamina, testosterone, hair, mood. The truth is more modest — and more useful.

This guide covers what shilajit is, what published research actually found, what remains unproven, and how to choose a safe product if you decide to try it.

What is shilajit?

Shilajit is a sticky, tar-like substance that seeps from rocks in the Himalayas, formed over centuries from decomposed plant material. Its main active compound is fulvic acid, along with dozens of trace minerals.

In Ayurveda it has been used for generations as a rasayana (rejuvenator). Modern research is newer and much smaller in scale — a handful of human trials, most with fewer than 100 participants.

What research suggests it may help with

Testosterone. One frequently cited 90-day trial in men aged 45-55 found a statistically significant increase in total testosterone versus placebo at 250 mg of purified shilajit twice daily. That's one small study — encouraging, not conclusive. If you have symptoms of genuinely low testosterone (persistent fatigue, low libido, loss of muscle), get a blood test and talk to a doctor rather than self-treating.

Fatigue and recovery. Small studies suggest shilajit may support mitochondrial function, which is the biological basis of the "energy" claims. Effects, where found, were modest.

Altitude and general wellness. Traditional use for altitude sickness has some preliminary support, but this is not relevant for most users.

What it does NOT do

Being honest about limits matters more in men's health than anywhere else:

• It is not a treatment for erectile difficulties or premature ejaculation. No supplement is. These have medical causes that a doctor can actually address — and modern consultation is discreet and judgment-free.
• It will not transform your physique. No supplement replaces progressive training, protein and sleep.
• It is not "natural Viagra." Anyone marketing it that way is breaking Indian advertising law and should not get your money.

How to choose a safe product

1. Purified resin or capsules only. Raw shilajit can carry lead, arsenic and mercury.
2. Third-party lab testing. Reputable brands publish heavy-metal and purity certificates. No certificate, no purchase.
3. Sensible dosing. Research used 250-500 mg per day of purified extract. More is not better.
4. Check interactions. Skip it if you have gout or iron-overload conditions, and consult a doctor if you take diabetes or blood-pressure medication.

The bottom line

Shilajit is a reasonable, generally safe supplement with modest evidence for testosterone support and fatigue — and inflated marketing far beyond that evidence. Fix sleep, training and food first; they out-perform any supplement. If you do add shilajit, buy purified and tested, give it 8-12 weeks, and judge by how you actually feel.
