Research suggests shilajit may support testosterone levels, sperm health, energy, and physical performance in men, but most studies are small, several were funded by supplement makers, and some findings come only from animal research. Below, we break down each potential benefit, how strong the evidence really is, how much men typically take, and who should avoid it.
Before we start, here’s a quick summary of where the evidence stands today:
| Benefit | Evidence level | What was studied |
|---|---|---|
| Testosterone | Moderate (one controlled human trial) | Healthy men aged 45–55, 90 days |
| Sperm count and motility | Limited (small human study) | Infertile men, 90 days |
| Energy and fatigue | Limited (mostly animal studies) | Fatigue models in rats |
| Muscle strength and recovery | Limited (one human trial) | Recreationally active men, 8 weeks |
| Libido and sexual health | Weak (traditional use, indirect evidence) | No direct human trials |
| Healthy aging | Early (lab and animal studies) | Antioxidant and cellular research |

What Is Shilajit and Why Is It Popular Among Men?
Shilajit is a sticky, dark brown resin that seeps from rocks in high mountain ranges like the Himalayas, the Hindu Kush, and the Altai. It forms over centuries as plant material breaks down and mixes with minerals. Its main active compound is fulvic acid, along with smaller compounds called dibenzo-alpha-pyrones and dozens of trace minerals.
In Ayurveda, shilajit is classed as a Rasayana (a rejuvenating substance) and is also used in Vajikarana, the branch of traditional medicine focused on male vitality and reproductive health. That long history is a big reason it’s marketed so heavily to men today. Modern research has started testing some of these traditional claims, with mixed but interesting results. For the full background, read our guide on what is shilajit.
Does Shilajit Increase Testosterone in Men?
One well-designed clinical trial found that purified shilajit raised testosterone in healthy middle-aged men after 90 days. This is the strongest piece of evidence for any shilajit benefit in men.
The study, published in Andrologia in 2016 by Pandit and colleagues, was randomized, double-blind, and placebo-controlled, which is the gold standard design. It was conducted at the J.B. Roy State Ayurvedic Medical College and Hospital in Kolkata, India, and included 75 healthy volunteers aged 45–55, who took either purified shilajit or a placebo for 90 days, with blood tests at 0, 30, 60, and 90 days. The dose was 250 mg twice daily. nutritionaloutlook
After 90 days, the shilajit group showed about a 20% increase in total testosterone and a 19% increase in free testosterone. The researchers also reported that levels of LH and FSH, the hormones that signal the body to make testosterone, were maintained, while DHEA-S, a testosterone precursor, increased. That matters because synthetic testosterone usually suppresses these hormones. nutritionaloutlooksoin-et-nature
Here’s the honest context you won’t find on most sales pages:
- It’s essentially one human trial. Results need to be repeated by independent research teams.
- The study used a specific branded, purified extract (PrimaVie). Raw or unverified shilajit may not behave the same way.
- The authors themselves described the result as preliminary and called for larger and longer studies. norfolkdailynews
- There’s no good data on younger men with already normal testosterone levels.
So shilajit may offer a modest boost in men in their late 40s and 50s, but it’s not a replacement for medical treatment of low testosterone. If you have symptoms of low T, such as persistent fatigue, low libido, or loss of muscle, get a blood test first. For a deeper look at the study and what it means, see our article on whether shilajit increases testosterone.
Can Shilajit Improve Sperm Count and Male Fertility?
A small study found improved sperm count and motility in infertile men who took processed shilajit for 90 days, but the evidence is limited and needs confirmation.
In this 2010 study by Biswas and colleagues, infertile men with low sperm counts took 100 mg of processed shilajit twice daily for 90 days. Researchers reported increases in total sperm count, sperm motility, and testosterone, along with lower markers of oxidative stress. Oxidative stress damages sperm cells, so this effect could explain part of the result.
The problem is the study design. It was small, and it did not include a proper placebo group, which makes it hard to know how much of the change was caused by shilajit. Animal studies point in the same direction, but animal results don’t always carry over to humans.
If you and your partner are trying to conceive and it isn’t happening, see a doctor or fertility specialist before turning to supplements. Male fertility problems have many causes, and some are easy to treat once diagnosed. Learn more in our guide to shilajit for male fertility.
Does Shilajit Help With Energy and Fatigue?
Shilajit may help with energy at the cellular level, but most evidence for this comes from animal studies, not human trials.
The theory is that shilajit supports mitochondria, the parts of your cells that produce energy in the form of ATP. Some research suggests it works alongside CoQ10, a compound your body uses to make cellular energy. In rat studies, shilajit reduced signs of chronic fatigue and helped preserve mitochondrial function.
Many men report feeling more energetic after taking shilajit, but personal reports aren’t proof, and the placebo effect is strong with energy supplements. Fatigue can also be a sign of poor sleep, low iron, thyroid problems, or depression, so if you’re constantly tired, it’s worth getting checked. Our guide on shilajit for energy covers the research in more detail.
Shilajit for Stamina, Muscle Strength, and Workout Recovery
One human trial suggests shilajit may help men keep their strength after tough workouts, though the effect was modest.
A 2019 study by Keller and colleagues, published in the Journal of the International Society of Sports Nutrition, gave recreationally active men either a placebo or purified shilajit at 250 mg or 500 mg per day for eight weeks. Men taking the 500 mg dose were better able to maintain their maximum muscle strength after a fatiguing exercise test. The researchers also measured markers suggesting shilajit may help protect collagen, the protein in tendons and connective tissue.
That’s promising for gym-goers and athletes, but it’s one study with a specific extract. Shilajit isn’t a substitute for training, sleep, and protein. If you lift weights, see our article on shilajit for bodybuilding and muscle recovery.
Shilajit for Libido and Sexual Health
Shilajit has a long traditional reputation for boosting male libido, but no strong human trials have tested this directly.
The idea is indirect: if shilajit modestly raises testosterone in some men, it might also support sex drive, since testosterone plays a role in libido. Its traditional use in Ayurvedic Vajikarana therapy is also often cited. However, there’s no solid clinical evidence that shilajit improves erectile function or sexual performance on its own, and it does not work like prescription drugs for erectile dysfunction.
Erectile problems can be an early sign of heart disease, diabetes, or high blood pressure, so they deserve a proper medical check rather than self-treatment. Read more in our guide on shilajit for libido.
Shilajit for Healthy Aging in Men
Shilajit contains antioxidant compounds that may support healthy aging, but this research is still at an early stage.
Fulvic acid, the main compound in shilajit, has antioxidant and anti-inflammatory properties in lab studies. Researchers have also explored shilajit’s possible role in brain health, including how it may affect proteins linked to cognitive decline. These are interesting directions, but most findings come from test tubes and animals. We explain the science behind this key compound in our article on fulvic acid benefits.
Shilajit Benefits for Men by Age
What shilajit can realistically do depends a lot on your age and starting health.
Men in Their 20s and 30s
Most young, healthy men already have normal testosterone levels, and there’s no research showing shilajit raises testosterone meaningfully in this group. Some younger men take it for energy or workout recovery. If that’s your goal, sleep, strength training, and a good diet will make a much bigger difference than any supplement.
Men Over 40
Testosterone gradually declines with age, roughly around 1% per year after the 30s or 40s in many men. This is the age group closest to the one studied in the main testosterone trial, so if shilajit helps anyone, men in their 40s and 50s are the most likely to notice a modest effect.
Men Over 50
Men over 50 match the upper end of the testosterone study’s age range. But this group is also more likely to take medications for blood pressure, diabetes, or heart health, which makes it important to check with a doctor first. See our dedicated guide to shilajit for men over 50.
How Much Shilajit Should Men Take?
Most human studies used between 250 mg and 500 mg of purified shilajit per day, often split into two doses.
For resin, a common serving is about the size of a grain of rice to a pea, dissolved in warm water, milk, or tea. Because products vary a lot in strength, always follow the dosage on your product’s label and start at the low end. Don’t take more than the label says, and don’t assume more is better. Our full guide on how to take shilajit covers dosing, timing, and different forms.
How Long Does It Take for Shilajit to Work in Men?
Expect to wait at least 8 to 12 weeks before judging whether shilajit is working for you.
The key studies on testosterone and fertility ran for 90 days, and the muscle strength study ran for eight weeks. Some men say they feel more energetic within a couple of weeks, but measurable changes in hormones or sperm take longer, since a full sperm production cycle alone takes about two to three months. Learn what to expect week by week in our guide on how long shilajit takes to work.
Shilajit Side Effects in Men: Who Should Avoid It?
Purified shilajit was well tolerated in clinical studies, but raw or low-quality shilajit can be contaminated with heavy metals, fungi, or other impurities.
Men should be especially careful or avoid shilajit if they:
- Have gout or high uric acid levels.
- Have hemochromatosis or other conditions involving excess iron.
- Have hormone-sensitive conditions, such as prostate cancer, since shilajit may raise testosterone.
- Take medications for blood pressure, diabetes, or heart conditions, because shilajit may interact with them.
- Have kidney or liver disease.
Possible side effects include stomach upset, headache, dizziness, and allergic reactions. Stop taking it and see a doctor if you notice anything unusual. Read our full guide on shilajit side effects.
Can Men Take Shilajit With Ashwagandha or Other Supplements?
Many men combine shilajit with ashwagandha, tongkat ali, or maca, but there’s little research on how these combinations work together.
Ashwagandha has its own human research for stress and testosterone, and combining it with shilajit is common in Ayurvedic practice. However, stacking several hormone-related supplements makes it harder to know what’s helping and raises the chance of side effects. Introduce one supplement at a time and talk to your doctor if you take any medication. We compare the two in shilajit vs ashwagandha.
How to Choose Pure Shilajit
The benefits in research come from purified, tested shilajit, so quality matters more than almost anything else.
Look for a product with a third-party lab report (Certificate of Analysis) that shows testing for heavy metals like lead, arsenic, and mercury, along with fulvic acid content. Avoid sellers who make miracle claims or won’t share test results. Our guide on how to identify pure shilajit walks through six practical tests.
FAQs
Is it good for men to take shilajit daily?
Studies gave men shilajit daily for up to 90 days without serious side effects, as long as it was a purified product. Long-term safety beyond that isn’t well studied, so some people take breaks every few months. Ask your doctor what’s right for you.
Can young men take shilajit?
Healthy adult men can take it, but there’s no evidence it raises testosterone in younger men with normal levels. It isn’t recommended for anyone under 18.
Does shilajit increase size?
No. There is no scientific evidence that shilajit, or any supplement, increases penis size. Claims like this are marketing myths, and products promising it should be treated as a red flag.
Is shilajit like Viagra?
No. Prescription drugs for erectile dysfunction work directly on blood flow and have strong clinical evidence. Shilajit has no proven effect on erections, and any effect on libido would be indirect and modest.
Can shilajit cause hair loss in men?
There’s no direct evidence that shilajit causes hair loss. Some men worry about it because higher testosterone can convert to DHT, which is linked to male pattern baldness, but no study has shown this effect from shilajit.
Should men take shilajit in the morning or at night?
Most people take it in the morning or early afternoon, since some feel more energetic after taking it. Studies often gave it after meals. Consistency matters more than exact timing. See our guide on the best time to take shilajit.
The Bottom Line
Shilajit shows real promise for men, especially for testosterone support in middle-aged men, but the evidence is still early and based on a small number of studies. It’s best seen as a supplement that may offer modest support alongside healthy habits, not as a cure or replacement for medical care. If you decide to try it, choose a lab-tested product, stick to the studied doses, give it about three months, and check with your doctor first if you have any health conditions or take medication.
