Shilajit Benefits for Men: What the Research Actually Shows (2026)
By Bulldog Nutrition Editorial Team | Updated: August 2026
Quick Answer
The strongest research on shilajit for men centres on hormone support and fertility: in a 90-day placebo-controlled trial, healthy men taking 250 mg of purified shilajit twice daily saw an average 20% increase in total testosterone versus placebo, and a separate 90-day clinical study in men with low sperm counts reported a 61% increase in sperm count. These are small studies and not a guarantee for every man — but they're why shilajit has become a staple in men's wellness routines. If you try it, the research argues for one thing above all: a purified, standardized product, like Himalaya Shilajit.
Shilajit is having a moment with Canadian men — and unlike a lot of supplement trends, there's actual published human research underneath the noise. There's also a lot of exaggeration layered on top of it. This guide goes through what the studies genuinely found, what they didn't, and what that means practically if you're considering shilajit as part of a training or wellness routine.

What Is Shilajit? (30-Second Version)
Shilajit is a mineral-rich exudate formed over centuries in high-altitude rock, used in Ayurvedic tradition for thousands of years as a rejuvenating tonic for strength and vitality. Its key actives are fulvic acids — a quality purified extract is standardized to a stated percentage — plus dozens of trace minerals. It's not a stimulant; its effects in studies emerge over weeks of daily use.
Shilajit and Testosterone: What the Study Actually Found
The study everyone quotes is a randomized, double-blind, placebo-controlled trial published in Andrologia (2016). Healthy men aged 45–55 took 250 mg of purified shilajit twice daily for 90 days. Compared with placebo, the shilajit group showed an average increase of roughly 20% in total testosterone and 19% in free testosterone (study on PubMed).
Three honest caveats before you extrapolate:
- It was a small trial — around 75 completers — and results in one demographic (middle-aged men) don't automatically transfer to a 25-year-old with already-healthy levels.
- The material was purified, standardized shilajit at a defined dose — not raw resin of unknown concentration from a marketplace listing.
- A 20% shift within normal ranges is meaningful but not a pharmaceutical effect. Nobody's bloodwork transforms in a week.
That's the fair reading: promising, placebo-controlled, and worth replicating in larger trials — which is more than most trending supplements can say.
Shilajit and Male Fertility
The second major line of research is fertility. In a 90-day clinical study published in Andrologia (2010), men with low sperm counts (oligospermia) took processed shilajit twice daily. Reported outcomes included a 61.4% increase in total sperm count, an 18.9% rise in normally shaped sperm, and a 37.6% increase in semen volume (study on PubMed). Follicle-stimulating and luteinizing hormone levels stayed stable, suggesting support of normal reproductive function rather than disruption of it.
Again: one study, specific population, encouraging numbers. Men with diagnosed fertility concerns should be working with a physician — shilajit is not a treatment for infertility.
Energy, Recovery, and the Fulvic Acid Mechanism
Why would a tar-like mountain mineral affect hormones and energy at all? The leading explanation is cellular: fulvic acid appears to support mitochondrial energy production and nutrient transport into cells, and shilajit's mineral complex feeds the same machinery — a mechanism explored in published pharmacological reviews (review on PubMed Central). For men who train, that's the practical angle: shilajit is used as a daily foundation for energy and recovery, not a pre-workout you feel in 30 minutes. It also provides antioxidants that help protect cells against free radical damage — oxidative stress being one of the things hard training generates plenty of.
What the Evidence Does NOT Show
This section is where we differ from the hype blogs, so let's be direct:
- No large-scale trials yet. The human studies are small. Encouraging is not the same as established.
- Not a testosterone replacement. If you have clinically low testosterone with symptoms, that's a conversation with your doctor, not a supplement aisle decision.
- No disease claims. Shilajit doesn't treat, cure, or prevent any condition, and any seller telling you otherwise is telling you something about themselves.
- Results depend on the material. The trials used purified, standardized shilajit. Unpurified raw resin is a different — and riskier — product entirely.
Safety: Who Should Skip Shilajit
Purified, tested shilajit is well tolerated by most healthy adult men at label doses. The cautions worth knowing: skip it if you're under 18; consult a healthcare practitioner first if you have gout, diabetes, kidney concerns, or take medications that raise uric acid; and never buy unpurified raw shilajit — the documented safety problems in this category (heavy metals, adulteration) come almost entirely from untested material. Standard practice is up to three months of continuous use, then a check-in with a practitioner. Always read the full label.
How Men Typically Take Shilajit
The studied pattern is simple: 250–500 mg of purified extract daily, taken consistently for at least 8–12 weeks. Himalaya Shilajit delivers 250 mg of purified resin extract standardized to 60% fulvic acids in two daily capsules — sourced from high-altitude Himalayan regions and tested in a cGMP-certified facility. Men building a broader performance stack sometimes prefer it combined with other supported ingredients — ATP Lab Alpha Jack includes shilajit inside a complete natural testosterone-support formula. Morning or evening doesn't matter; daily consistency does.
FAQ
Does shilajit really increase testosterone?
In the one placebo-controlled human trial to date, men taking purified shilajit for 90 days saw about a 20% average increase in total testosterone versus placebo. It's a promising result from a small study — supportive, not conclusive, and individual responses vary.
How long does shilajit take to work?
The published studies ran 90 days, and that's the honest expectation-setter: this is a weeks-to-months supplement, not a same-day one. Give it 8–12 weeks of consistent daily use before judging.
Is shilajit safe for daily use?
Purified, tested shilajit is well tolerated by most healthy adults at label doses for up to three months of continuous use. The real safety risk in this category is unpurified raw resin from unverified sellers — buy tested products from established retailers.
Should I take shilajit or ashwagandha?
They do different jobs: ashwagandha is the better-studied option for stress and sleep support, while shilajit's research centres on male hormone support, fertility, and cellular energy. Plenty of men take both — see our ashwagandha guide for that side of the decision.
What's the best shilajit for men in Canada?
A purified capsule standardized for fulvic acid content from an authorized retailer — our top pick and full reasoning are in the best shilajit in Canada guide. Bulldog Nutrition is an authorized Canadian and US retailer, so every bottle is sourced directly and 100% authentic.
