Can Shilajit Treat Erectile Dysfunction (ED) and Premature Ejaculation (PE)? What Medical Science Says
Published 8 Feb 2025 · Updated 2 Oct 2026 · 7 min read
Short answer
No. Shilajit is not a proven treatment for erectile dysfunction (ED) or premature ejaculation (PE). A few small studies suggest it may modestly raise testosterone or energy in some men, but there is no good evidence that it fixes erections or ejaculation timing. Prescription options such as Tadalafil, Sildenafil and Dapoxetine have far stronger evidence and are standardised and doctor-supervised.
Will Shilajit fix my ED or PE?
Very unlikely. Many men tell us they saw an advertisement, or a friend said, that Shilajit fixes erections and timing for good, and they ask whether they really need a prescription medicine at all.
Shilajit is not a targeted sexual medicine. Erectile dysfunction (ED) is mainly a problem of blood supply and the smooth muscle of the penile blood vessels, often linked to diabetes, cholesterol, blood pressure, hormones or anxiety. Premature ejaculation (PE) is mostly a problem of brain and nerve signalling, in which serotonin plays a major role. Shilajit has not been shown to treat either pathway directly.

How do herbal supplements differ from prescription medicines?
They differ in how precisely they act, how well they are studied and how consistent each dose is.
- Herbal / Shilajit supplement
- General nutrients and plant compounds
- Slow, uncertain effect
- No proven repair of blood flow or ejaculation control
- Prescription ED / PE medicine
- Acts on a known enzyme or receptor (PDE5, serotonin)
- Fast, predictable effect
- Doctor-monitored outcome
- Targeted action: a prescription medicine acts on one specific enzyme or receptor. For example, PDE5 inhibitors block the PDE5 enzyme to improve blood flow into the penis.
- Standardisation: a Tadalafil 5 mg tablet contains a measured, tested amount of drug. A Shilajit product may contain very different amounts of active compounds from one brand or batch to the next, and there is little regulation to check it.
Why does Shilajit often fail in real ED and PE?
Because it does not act on the underlying cause. When a man has vascular ED, diabetic nerve damage or significant PE, Shilajit tends to disappoint for these reasons:
- No proven effect on blood flow: there is no good evidence that Shilajit relaxes the arteries of the penis the way PDE5 inhibitors do.
- No proven control over ejaculation: delaying ejaculation involves serotonin signalling in the brain and spinal reflex. Shilajit has not been shown to change this.
- At best a modest, slow effect: a few small trials suggest that purified Shilajit may raise testosterone a little or improve energy over about three months in some men. That is not the same as treating erection failure, and the studies are small and limited.
Doctors also check testosterone because low levels can contribute to ED and low desire. If yours is truly low, see our guide on low testosterone symptoms and treatment before you try a supplement.
How does an erection actually work?
An erection is a blood-flow and nerve event, and it follows a fixed sequence.
- Arousal signal from the brain
- Nerves release nitric oxide (NO) in the penis
- NO raises cGMP and the blood vessels relax
- Blood fills the penis and the erection forms
The enzyme PDE5 breaks down cGMP, and that is what lets an erection fade. PDE5 inhibitors such as Tadalafil and Sildenafil temporarily block this enzyme, so cGMP stays higher and sexual stimulation produces a firmer, longer-lasting erection. They still need sexual arousal to work. Shilajit has no known PDE5-blocking action.
What are the proven medical treatments for ED and PE?
For ED, the proven options are PDE5 inhibitors (Sildenafil, Tadalafil, Vardenafil), which are FDA-approved and help roughly two-thirds to three-quarters of men. For PE, the main options are Dapoxetine and topical anaesthetic sprays.
Erectile dysfunction (ED)
- Daily low-dose Tadalafil (5 mg): keeps the penile blood vessels relaxed and supports their lining, and many men find it removes the pressure to time sex. It reaches a steady level in about a week.
- On-demand Sildenafil or Tadalafil: taken before sex, with Sildenafil usually working in about 30 to 60 minutes. Doses are set by the doctor.
Premature ejaculation (PE)
- Dapoxetine (30 mg or 60 mg): a short-acting SSRI taken on demand. It is approved for PE in India and many European and Asian countries, though not by the US FDA. On average it lengthens the time to ejaculation roughly two to three times.
- Topical anaesthetic sprays (lidocaine): reduce glans sensitivity for a short time and can improve timing.

Shilajit vs prescription treatment: how do they compare?
| Parameter | Shilajit / herbal supplements | Prescription treatment (PDE5 inhibitor / Dapoxetine) |
|---|---|---|
| Category | General dietary supplement | Prescription medicine with clinical trial evidence |
| Main action | General nutrient or tonic effect, not targeted | Acts on blood-flow enzyme (PDE5) or serotonin signalling |
| Onset | Weeks to months, outcome uncertain | Usually within 30 to 60 minutes when taken as directed |
| Evidence in ED / PE | Very limited, small studies only | Strong, from many large trials |
| Dose consistency | Varies by brand and batch | Exact, tested dose (for example 5 mg, 10 mg, 30 mg) |
| Safety oversight | Little regulation, contamination risk | Prescribed and monitored by a doctor |
Are Shilajit and other herbal supplements safe?
Not always. The main concern is quality control, because "natural" does not mean safe. Many men assume herbal products carry no risk, but the evidence points to three problems:
- Heavy-metal contamination: unpurified or cheap Shilajit and other raw mineral products have been found to contain lead, mercury and arsenic. Long-term exposure can harm the liver, kidneys and nerves.
- Hidden drugs: the FDA has repeatedly found "herbal" sexual enhancement products secretly laced with Sildenafil or similar drugs in unmeasured amounts. This can be dangerous for men with heart disease or those who take nitrates. See the FDA warning on tainted sexual enhancement products.
- Delay in diagnosis: months spent on supplements can hide diabetes, heart disease or low testosterone that needed treatment.
Ashwagandha and Safed Musli are in a similar position. A few small trials suggest Ashwagandha may modestly help stress and testosterone, but the evidence is limited and quality varies between brands. None of these replaces a proper diagnosis.
Which tests should I get before trying any treatment?
A doctor should look for the cause before you rely on any medicine, herbal or prescription. The usual first tests are:
- Serum total and free testosterone (morning sample, around 8 AM): to check your main male hormone.
- Fasting blood sugar and HbA1c: to rule out silent diabetes and nerve damage.
- Lipid profile (cholesterol): because artery blockage in the penis often mirrors that in the heart.
- Penile Doppler ultrasound (only in selected men): to assess blood-flow speed and venous leak.
What does a sensible treatment journey look like?
- Proper tests
- Find the root cause
- Low-dose prescription therapy
- Confidence returns
- Review and reduce if suitable
The aim is not to keep you on medicine for ever. For many men, a period of effective treatment, together with fixing sleep, exercise, diabetes, weight and stress, restores both blood-vessel function and confidence. Some men do need long-term treatment, and that is also fine.
Myth vs fact
Myth Shilajit is better than medicines because it has no side effects.
Fact Unregulated Shilajit can contain heavy metals that harm the liver and kidneys, and some products have been found laced with hidden drugs. Prescription medicines are tested, standardised and monitored.
Myth Shilajit gives instant, Viagra-like erections and timing.
Fact Shilajit has no known PDE5-blocking action, so it cannot produce a fast, predictable erection the way Sildenafil or Tadalafil can.
Myth Prescription ED medicines are habit-forming.
Fact Tadalafil and Sildenafil are not habit-forming. They can be taken as needed under a doctor's guidance and stopped when no longer required.

Can I take Shilajit along with ED medicine?
Shilajit is sometimes taken as a general tonic, but it should not be counted on to treat ED or PE. Tell your doctor about every supplement you use, because quality varies and contaminated products can interact badly with prescription medicines. Prescription treatment should remain the main therapy.
How long does Tadalafil 5 mg daily take to work?
Daily Tadalafil builds to a steady level in the body over roughly a week, and many men notice more reliable erections within one to two weeks. Results differ from man to man, and the dose and plan should be set by your doctor.
Why do I still lose my erection even though I take Shilajit?
Your ED may come from a blocked blood supply, diabetes, low testosterone or stress and anxiety. Shilajit does not treat these causes. A doctor can find which one applies to you and treat it directly.
Which is the best medicine for premature ejaculation?
Dapoxetine (30 mg or 60 mg) is the main on-demand medicine made for PE. It works on serotonin and usually lengthens the time to ejaculation about two to three times. It is approved in India and many other countries, though not by the US FDA, and a doctor should decide whether it suits you.
Is it safe to buy sexual enhancement products online?
It is risky. Regulators such as the US FDA have found many online "natural" products secretly containing drugs like Sildenafil, in unknown doses. If you have heart problems or take nitrates, this can be dangerous.
