Shilajit, a sticky resin that seeps from rocks in the Himalayan mountains, has been used in Ayurvedic medicine for thousands of years. In recent years, it has gained significant attention as a natural supplement for men seeking to boost testosterone, improve fertility, and increase energy levels. But what does the science actually say?
While the traditional use of shilajit spans millennia, modern clinical research into its effects on male health is still in its early stages. A handful of small but promising studies suggest benefits for hormone levels and sperm health, yet experts caution that the evidence base remains limited, and product quality varies widely across the market.
This article examines the available clinical data on shilajit for men, covering testosterone, fertility, energy, dosage, safety concerns, and what remains unknown. The goal is to provide a clear, evidence-based picture for anyone considering this supplement.
What Are the Key Benefits of Shilajit for Men?
The most frequently cited benefits of shilajit for men revolve around hormonal health, reproductive function, and vitality. Below is a quick overview of the main areas where research has been conducted.
Benefits
May boost testosterone, increase energy, improve sperm health, support cognitive function, and enhance exercise performance. Based on preliminary clinical studies.
Side Effects
Generally mild: digestive upset, insomnia, dizziness. Risk of heavy metal contamination from low-quality sources. Consult doctor if on medication.
Dosage
Typical dose: 300–500 mg daily (standardized to fulvic acid). Start low and increase. Forms: resin (traditional), powder, capsules. Best taken with food.
Evidence Level
Limited but promising. Testosterone increase supported by a few small trials. Fertility improvements observed. Most benefits still need larger, long-term studies.
Here are the key insights from the existing clinical research:
- A controlled trial found that 500 mg of purified shilajit daily increased total testosterone by 23.5% in healthy men aged 45–55 after 90 days.
- Shilajit may improve sperm count, motility, and overall fertility, likely due to the antioxidant properties of its active component, fulvic acid.
- Fatigue reduction of up to 32.4% was reported in one clinical study, lending some support to its traditional use as an energy booster.
- Heavy metal contamination (lead, arsenic, mercury) is a significant safety concern, especially with unregulated products.
- Shilajit is not a direct sexual performance drug, but it may support libido indirectly through testosterone modulation and increased energy.

Does Shilajit Increase Testosterone and Improve Fertility?
This is the most researched area of shilajit’s effects on male health, and the question that drives most interest in the supplement. The clinical data, while limited, points toward a genuine biological effect.
What the testosterone studies show
A randomized, double-blind, placebo-controlled trial published in 2016 examined the effects of purified shilajit on healthy men aged 45 to 55. Participants took 250 mg twice daily for 90 days. The shilajit group showed significantly higher levels of total testosterone, free testosterone, and DHEAS compared to the placebo group. These results suggest that shilajit may support the aging male endocrine system.
In the key testosterone trial, the increase was about 23.5% over baseline for total testosterone. However, the study included only 60 men, and the results have not yet been replicated in a larger, longer-term trial. Experts at the Cleveland Clinic describe the evidence as preliminary but worth noting.
Fertility and sperm health
A separate randomized trial focused on 28 men with oligospermia (low sperm count). Participants received 100 mg of processed shilajit twice daily for 90 days. The treatment group experienced a 61.4% increase in total sperm count, along with improvements in sperm motility in some individuals. These findings align with other reports suggesting benefits for male fertility.
The proposed mechanism involves fulvic acid’s antioxidant activity, which may reduce oxidative stress in reproductive tissues. However, the sample sizes in these studies are small, and longer follow-up periods are needed to confirm whether these improvements translate into higher pregnancy rates.
What about prostate health?
Despite being a common question online, there is no convincing human clinical evidence that shilajit directly benefits prostate health or reduces prostate enlargement. Because shilajit may raise testosterone levels, men with existing prostate conditions should exercise caution. The absence of evidence for harm is not the same as evidence of safety, and this area remains understudied.
What Are the Side Effects and Safety Concerns of Shilajit?
Safety is a critical topic for any supplement, and shilajit has specific risks that consumers need to understand before purchasing or using it.
Common side effects
In clinical studies where purified shilajit was used, the supplement was generally well tolerated. Reported adverse effects include mild gastrointestinal upset such as nausea, vomiting, and diarrhea, as well as headache, dizziness, and occasional allergic reactions. These effects are typically mild and resolve on their own.
Heavy metal contamination
The most significant safety concern with shilajit is product contamination. Because shilajit is a natural resin that absorbs minerals from the surrounding rock, some products have been found to contain heavy metals including lead, mercury, and chromium. This risk is higher with raw, unpurified shilajit sold by less reputable suppliers.
Clinical reviews and medical sources, including Men’s Health UK and the Cleveland Clinic, consistently warn that heavy metal contamination is a real risk with unregulated shilajit products. Always choose supplements that provide third-party lab testing results for heavy metals. Purified shilajit in studies was well tolerated at doses up to 2,000 mg per day, but long-term safety beyond 90 days has not been established.
Long-term use
The available clinical trials have a maximum duration of 90 days. There is no robust data on the safety of daily shilajit use for longer periods. While no major liver, kidney, or blood abnormalities were reported in the existing short-term studies, researchers and clinicians agree that this does not prove safety over months or years of continuous use.
How to Take Shilajit: Dosage, Forms, and Best Practices
There is no universally accepted standard dose for shilajit, but the clinical studies provide useful reference points. Understanding the different forms and how to choose a quality product is essential for safe use.
Dosage used in clinical research
The two main human studies used different doses for different outcomes. For testosterone support, the regimen was 250 mg of purified shilajit twice daily (500 mg total) for 90 days. For fertility, the dose was 100 mg twice daily (200 mg total) for 90 days. Broader supplement discussions often mention a range of 200 to 500 mg per day for standardized extracts, with higher amounts sometimes used for raw resin.
Forms: resin, powder, and capsules
Shilajit is available in three primary forms. Resin is the traditional raw form, often considered the most potent but also the most variable in quality. Powder is typically standardized to a specific fulvic acid content and is easier to dose. Capsules offer convenience and precise dosing but may contain additives. The best choice depends on personal preference and the availability of third-party testing from the manufacturer.
UK-oriented guidance from sources like Goldman Laboratories emphasizes that the most important factor is whether the product is purified, standardized, and third-party tested for heavy metals. Terms like “shilajit gold” are marketing labels, not evidence-based medical categories. Look for a certificate of analysis from an independent lab before purchasing.
When and how to take it
Most recommendations suggest taking shilajit with food to reduce the risk of digestive upset. Some traditional sources recommend mixing the resin with warm milk or water. As with any supplement, starting with a lower dose and gradually increasing over a week or two allows the body to adjust.
Shilajit for Specific Health Concerns: Prostate, Women, and UK Availability
Beyond the core benefits for male hormonal and reproductive health, questions frequently arise about shilajit’s role for other conditions and populations.
Can women take shilajit?
Shilajit is not exclusively for men, but most clinical research has focused on male subjects. Some women use shilajit for energy and as a general wellness tonic. The same safety considerations apply regarding contamination and long-term use. Pregnant or breastfeeding women should consult a healthcare provider before taking any new supplement.
Prostate health: what the evidence says
As noted earlier, no human clinical studies have demonstrated a direct benefit of shilajit for prostate health or benign prostatic hyperplasia. The theoretical concern is that any supplement that raises testosterone could influence prostate tissue, so men with a history of prostate issues should seek medical advice before using shilajit.
Buying shilajit in the UK
For UK buyers, the priority should be finding a product that is purified and independently tested. The market includes many imported resins and extracts with varying quality standards. Look for brands that clearly state the origin of their shilajit (typically the Himalayas), the fulvic acid concentration, and that provide third-party heavy metal testing results. Regulatory oversight for supplements in the UK is less strict than for medicines, making buyer diligence essential.
Timeline of Shilajit Research and Popularity
Understanding the historical context helps clarify why the evidence base is still developing despite the supplement’s ancient roots.
- – First documented use in Ayurvedic texts (Charaka Samhita) as a rejuvenator and vitality promoter.
- – Modern chemical analysis identifies fulvic acid as the primary active component and begins to characterize its antioxidant properties.
- – The first randomized, double-blind, placebo-controlled trial on shilajit and testosterone is published, showing significant increases in total and free testosterone.
- – Further human studies on sperm parameters and energy levels are published, expanding the evidence base for male fertility.
- – Major media outlets including Men’s Health and the Cleveland Clinic publish articles on shilajit, driving consumer interest and product demand.
What We Know vs. What Remains Unclear
Separating established facts from areas of uncertainty is crucial for making informed decisions about shilajit supplementation.
| Established Information | What Remains Unclear |
|---|---|
| Shilajit contains fulvic acid and humic substances with confirmed antioxidant properties. | Most studies have small sample sizes (20–60 participants) and short duration (90 days or less). |
| Small clinical trials suggest a positive effect on testosterone levels (up to 23.5% increase). | Long-term safety beyond 90 days of daily use has not been studied. |
| Improvements in sperm count and motility have been observed in a few studies. | Optimal dosage and form (resin vs. capsule) lack standardization across the industry. |
| Traditional use as an energy and vitality tonic is well documented in Ayurveda. | The mechanism of action for cognitive benefits is not established. |
| Interactions with medications such as blood thinners and diabetes drugs are not fully known. |
Analysis and Context: How Shilajit Works and Where It Fits
Fulvic acid, the primary active compound in shilajit, acts as a carrier for minerals and electrolytes. It is believed to improve mitochondrial function and cellular energy production by enhancing ATP synthesis. Its antioxidant activity may reduce oxidative stress in reproductive tissues and the brain, which could explain the observed effects on sperm health and cognitive function.
Compared to other male supplements, shilajit has a different mechanism than ashwagandha, which primarily works through stress reduction via cortisol modulation. Some users combine both supplements, but evidence for synergistic effects is lacking. Each has its own evidence base and should be evaluated independently.
The product quality landscape for shilajit is highly variable. Himalayan origin is often cited as a marker of quality, but third-party testing for heavy metals is the only reliable way to verify safety. The term “shilajit gold” is a marketing label used for certain preparations and does not indicate a medically distinct category.
