Is Shilajit Safe to Take Daily? Side Effects & What to Know Before Buying
Share
Yes, shilajit is safe for daily use at typical doses of 300-500mg when properly purified and third-party tested, with clinical studies involving 1,254 participants reporting only mild, transient side effects like gastrointestinal discomfort and headache that resolved without medical intervention.[1] The real safety concern isn't shilajit itself, it's contaminated products from unregulated sources. As of August 2026, the Therapeutic Goods Administration continues to receive reports of lead poisoning linked to imported or unregistered Ayurvedic medicines, with laboratory testing confirming the presence of lead, mercury and arsenic in several products.[2]
You've read about the energy and testosterone benefits. But before you spend money on shilajit, you need the complete picture on safety, side effects, and how to identify a product that won't put your health at risk.
What Clinical Research Says About Daily Use
The most rigorous human trial evaluated purified shilajit in healthy volunteers aged 45 to 55 years in a randomised, double-blind, placebo-controlled clinical study at a dose of 250 mg twice a day, with treatment for consecutive 90 days revealing significantly increased testosterone levels compared with placebo.[3] A 2026 clinical study followed healthy men who took 500 mg of shilajit every day for 28 days to monitor for side effects, blood cell count, and liver and kidney function, with researchers reporting no clinical side effects and no noticeable changes in blood tests.[4]
In clinical trials as of August 2026, shilajit dosing has ranged from 200 to 2000 mg daily, although the most commonly used dosing regimen is 500 mg daily, split into two daily doses.[5] The evidence shows that purified shilajit at studied doses is well-tolerated in healthy adults when taken consistently over 8-12 weeks.
Known Side Effects (And How Common They Are)
Most people experience no side effects from properly purified shilajit. When side effects do occur, they're typically mild and short-lived.
Digestive Upset
Gastrointestinal discomfort was the most commonly reported side effect in systematic reviews, with participants reporting symptoms such as nausea and abdominal cramps that were manageable and did not significantly impact their daily activities.[1] This usually resolves within the first week of use as your system adjusts.
Interactions with Medications
Shilajit may lower blood sugar and blood pressure. One human intervention with 200mg daily for 90 days was associated with a decrease in blood glucose by 6.8% relative to baseline in otherwise healthy males.[6] If you're on insulin, diabetes medications, or blood pressure medications, consult your GP before starting shilajit. The compound could enhance the effects of these drugs, potentially causing blood sugar or blood pressure to drop too low.
Hormonal Effects
Hormonal effects such as increased testosterone and follicle-stimulating hormone levels have been observed, thus indicating that individuals with hormone-sensitive conditions may experience adverse effects when taking shilajit.[7] If you have a hormone-sensitive condition like prostate cancer, breast cancer, or endometriosis, avoid shilajit unless your doctor specifically approves it.
Elevated Uric Acid
Shilajit contains purines, which break down into uric acid. If you have gout or a history of high uric acid levels, monitor your symptoms closely. Some users report flare-ups when taking higher doses consistently.
Allergic Reactions
Rare, but documented. If you develop a rash, itching, or difficulty breathing after taking shilajit, stop immediately and seek medical attention.
The Real Risk: Heavy Metal Contamination
This is the section that matters most for Australian buyers. Raw shilajit can contain heavy metals like lead, arsenic, and cadmium because it is a mineral-rich resin formed in mountain rocks, though high-quality shilajit undergoes extensive purification to remove harmful contaminants while retaining beneficial trace minerals, ensuring it meets strict safety standards.[8]
The problem is widespread. Testing of an Ayurvedic product labelled Brahmi Vati found that the tablets contain extremely high concentrations of heavy metals, including mercury, lead, arsenic, and cadmium.[9] A 2025 study found that some shilajit supplements actually had higher levels of the toxic heavy metal thallium than the raw variety.[10]
What Heavy Metals Do to Your Body
Lead, mercury, arsenic, and cadmium are the primary culprits that pose significant health risks, with these toxic metals accumulating in your body over time, potentially causing neurological damage, kidney problems, and cardiovascular issues.[11] Pregnant women and children face the greatest risk, but chronic low-level exposure damages anyone over time.
Why Australian Regulations Matter
In Australia, medicines such as Ayurvedic and traditional Chinese medicines are classified as 'complementary medicines', and are generally required to meet the same standards of quality and safety as other medicines.[12] To confirm if a product is on the Australian Register of Therapeutic Goods (ARTG), check for an AUST R or AUST L number on the packaging, which confirms that the medicine is included on the ARTG and meets Australian standards.[2]
But here's the catch: Despite safety warnings, the TGA continues to intercept unregistered Ayurvedic medicines imported into Australia that contain dangerous levels of heavy metals and other controlled or prohibited ingredients.[9] Products purchased from overseas websites, social media platforms, or unlicensed retailers bypass these protections entirely.
Who Should NOT Take Shilajit
Do not take shilajit if you fall into any of these categories:
- Pregnant or breastfeeding women: No safety data exists for this population. The risk is unknown, so avoidance is the only responsible choice
- People with haemochromatosis or iron overload disorders: Shilajit contains iron and could worsen iron accumulation
- Anyone on insulin or blood pressure medication: Consult your GP first due to potential interactions
- Children under 18: No paediatric safety data exists
- People with active gout or elevated uric acid: The purine content may trigger flare-ups
- Individuals with hormone-sensitive cancers or conditions: The hormonal effects make this a no-go zone without oncologist approval
Standard Dosage Guidance for Daily Use
For purified shilajit resin, most studies suggest starting with 300-500mg daily, taken with warm water or milk.[13] The sweet spot in clinical research has been 500 mg daily, typically split into two doses of 250 mg, with the most common regimen across trials being 500 mg daily, divided into two 250 mg doses.[14]
Morning timing on an empty stomach is common, though splitting the dose (morning and early afternoon) mirrors the protocol used in testosterone studies and keeps blood levels more consistent. Avoid evening doses if you're sensitive to stimulants, as some users report increased energy that interferes with sleep.
Some practitioners recommend cycling: 8-12 weeks on, then 2-4 weeks off. This is a precautionary approach, not based on evidence of toxicity, but rather on traditional Ayurvedic practice. Clinical trials have run continuously for 90 days without issues.
How to Buy Safely: What to Look For
Quality matters more for shilajit than almost any other supplement. Here's what separates safe products from dangerous ones.
Third-Party Lab Testing
Testing protocols for shilajit supplements should include ICP-MS for heavy metals (lead, mercury, arsenic, cadmium), comprehensive microbiological assessment, mycotoxin screening, and validated fulvic acid quantification.[15] ICP-MS (Inductively Coupled Plasma Mass Spectrometry) is the gold standard for trace metal analysis, capable of detecting metals at parts-per-billion concentrations, and is the method specified by USP for dietary supplement heavy metal testing.[16]
A Certificate of Analysis (COA) is non-negotiable. A COA should include specific test results for heavy metals, microbials, and fulvic acid content, listing the testing laboratory name, test dates, and batch numbers, with reputable manufacturers making these documents easily accessible on their websites or providing them upon request.[11]
If a company won't provide a COA for the specific batch you're buying, walk away. That's a red flag, not a minor omission.
Fulvic Acid Content
PrimaVie, a patented, purified shilajit extract used in many trials, is standardized to contain ≥50% fulvic acid and ≥10.3% DBPs/DCPs.[5] Quality resin typically contains 60-80% fulvic acid. If the label doesn't disclose fulvic acid percentage, you have no way to verify you're getting an effective dose.
Australian Retailer with Consumer Protections
Buy from an Australian retailer subject to Australian Consumer Law. You get recourse if something goes wrong, faster shipping, and local customer service. PurePeak, for example, offers third-party testing and a 60-day money-back guarantee, both signals that a company stands behind its product quality.
Warning Signs to Avoid
- No AUST L or AUST R number and sold in Australia
- No published COA or lab results
- Suspiciously cheap pricing (quality testing costs money; rock-bottom prices suggest corners were cut)
- Purchased from social media, unknown overseas websites, or unlicensed grocery stores
- No fulvic acid percentage listed
- Vague claims about "purity" without specific test results
What to Expect When You Start Taking Shilajit
If you're taking a properly tested product at standard doses, most people notice nothing negative. Some report mild digestive changes in the first few days as their system adjusts, dissolving the resin in warm water rather than taking it straight can reduce this.
Energy and cognitive benefits typically emerge within 2-3 weeks. Testosterone, body composition, and fertility benefits require 8-12 weeks of consistent daily use at clinical doses. If you experience persistent nausea, headaches, or any concerning symptoms, stop taking it and consult your GP.
Monitor your response. If you're on medications, track your blood sugar or blood pressure more frequently during the first month to catch any interactions early.
The Bottom Line
Shilajit is safe for most healthy adults when you buy from a tested, reputable source. The risks come from contaminated products, not the ingredient itself. The difference between a therapeutic supplement and a toxic one is invisible to the naked eye, it lives in lab reports, purification processes, and manufacturer accountability.
Before you buy, demand a current COA with heavy metals panel from a NATA-accredited or equivalent lab. Verify the fulvic acid content. Choose an Australian retailer with consumer protections. If a company can't or won't provide this information, they're asking you to gamble with your health. The answer is simple: don't.
For most people, the answer to "is shilajit safe to take daily?" is yes, with one critical caveat: only if it's been properly purified and independently tested. Anything less than that standard isn't worth the risk.
Frequently Asked Questions
Can I take shilajit if I'm on blood pressure medication?
Consult your GP before starting. Shilajit may lower blood pressure, which could enhance the effects of antihypertensive medications and cause your blood pressure to drop too low. Your doctor may need to adjust your medication dosage or monitor you more closely.
How long can I safely take shilajit without a break?
Clinical trials have run for 90 consecutive days without safety concerns. Some practitioners recommend cycling (8-12 weeks on, 2-4 weeks off) based on traditional Ayurvedic practice, but there's no evidence that continuous use at standard doses causes harm in healthy adults.
Is shilajit safe for women?
Yes, at 200-400mg daily for energy, iron support, and general wellness, provided you're not pregnant or breastfeeding. The same safety precautions apply: buy third-party tested products, avoid if you have hormone-sensitive conditions, and consult your GP if you're on medications.
What should I do if I've been taking untested shilajit?
Stop immediately. If you've experienced symptoms like fatigue, abdominal pain, cognitive issues, or neurological changes, see your GP and mention potential heavy metal exposure. They can order blood tests to check for lead, mercury, and arsenic levels. Switch to a third-party tested product with published COAs if you want to continue using shilajit.
Are shilajit gummies as safe as resin?
Safety depends on testing, not form. Gummies, capsules, and resin all require the same heavy metals screening and quality verification. Resin tends to have higher fulvic acid content and fewer additives, but a tested gummy is safer than untested resin. Always check the COA regardless of format.
