Is Shilajit Safe? What to Know Before Taking It

Purified versions of Shilajit have been used safely, but it’s very important to focus on the word purified. Shilajit naturally forms between layers of mountain rock, where decomposed plant material mixes with minerals over centuries. As a result, it gains fulvic acid, trace minerals, and humic substances. It also means poorly processed shilajit can carry unwanted substances such as heavy metals and microbes.

For most people, a purified product is generally very safe, especially when they follow the instructions on the label. Therefore, the real question is not about the safety of Shilajit itself, but rather about the safety of the product you’re holding in your hands.

This article will go over the available research that discusses the safety of purified Shilajit and how to make sure the product you purchase is risk-free.

Is Purified Shilajit Safe?

Human studies repeatedly found that purified Shilajit is very safe even if it’s taken for some time (up to 3 months).

A 2026 clinical study followed up healthy men who took 500 mg of Shilajit every day for 28 days. The purpose of the study was to monitor for side effects, blood cell count, and liver and kidney function. By the end of the study, researchers reported no clinical side effects and no noticeable changes in blood tests.

In another study that lasted 90 days and involved men with low sperm counts, participants took 100 mg of Shilajit twice a day. The monitoring of participants showed no side effects.

Purified shilajit has also been studied at 500 mg daily for testosterone and muscular performance without major safety concerns being reported.

Why Raw Shilajit Is a Different Story

Contrary to what the name may imply, raw Shilajit does not necessarily mean a stronger or more authentic version of purified Shilajit. Raw Shilajit can actually contain soil-derived metals, microorganisms, fungal toxins, and other unwanted substances. A review of shilajit chemistry warns us that the consumption of this substance without purification can actually lead to intoxication from heavy metals and mycotoxins.

Remember, the goal of purification is to remove these harmful compounds but conserve fulvic acid and other beneficial substances. For this reason, reading that the product is “straight from the Himalayas” shouldn’t be a selling point. Once again, mountain resin has not passed a quality test simply because someone filmed it next to an impressive cliff.

Heavy Metals Are the Main Quality Concern

Shilajit interacts with the mineral-rich environment in which it forms. Small amounts of metals are therefore not surprising, but the type and concentration matter.

A 2024 review identified dozens of metals found in shilajit, including lead, arsenic, cadmium, and mercury. This review confirmed that the concentrations of these metals were still in the normal range. However, other studies reported that the levels can exceed the safe limit.

A more recent analytical study measured thallium in raw shilajit and six commercial supplements. Some finished supplements contained more thallium than the raw material, and one provided up to 0.095 micrograms per tablet.

Obviously, the study does not prove that all Shilajit supplements are contaminated. However, it does show us that the testing of the raw ingredient alone may not be enough. The best scenario is that a company tests the finished batch that actually reached customers.

What Side Effects Can Shilajit Cause?

Purified shilajit can cause the following side effects:

• Nausea and digestive discomfort.
• Diarrhea.
• Headache.
• Dizziness.
• Skin irritation.

Stop taking shilajit if you develop persistent digestive symptoms, a rash, or unusual dizziness.

Difficulty breathing, swelling of the lips or tongue, widespread hives, confusion, and severe vomiting require urgent medical attention.

Who Should Avoid Shilajit?

Pregnant or breastfeeding women should avoid it because there is not enough safety research in these groups. Children should not take it unless it’s specifically recommended by a certified healthcare professional.

Here are a few conditions that we recommend you speak with your doctor before you take Shilajit:

• Kidney or liver disease.
• Hemochromatosis or other iron-overload disorders.
• A known sensitivity to minerals or humic substances.
• A hormone-sensitive condition.
• Take regular prescription medication.
• Programmed for surgery.

It’s worth noting that Shilajit has been shown to affect testosterone and other biological markers in some studies. Although this is part of why people take it, you should not assume it is an inactive mineral supplement.

Can You Take Shilajit Every Day?

Most clinical research has used shilajit every day. Daily amounts fall around 200-500 mg. However, the dose depends on the concentration and formulation. These studies lasted 4 to 12 weeks.

A high dose does not necessarily mean the supplement will work faster. In fact, it can fire back and cause stomach upset and other digestive issues.

Follow the serving directions on the label and don’t copy a dose from a random study that probably used a different extract. Resin, powder, capsules, and concentrated gummies are not necessarily equivalent milligram for milligram.

How to Tell Whether a Shilajit Product Is Safe

Look for a current Certificate of Analysis (i.e., COA). This is a laboratory report that shows what a specific product batch contains.

A useful COA should test for:

• Lead.
• Arsenic.
• Mercury.
• Cadmium.
• Thallium.
• Microbial contamination.
• Mould and yeast.
• Product potency.

At the same time, the report should identify the independent laboratory, batch number, test date, and measured results. You should also know the amount of shilajit per serving. Avoid products that hide it inside a proprietary blend or rely on phrases such as “maximum Himalayan power” instead of actual numbers.

FAQs About Shilajit Safety

Conclusion

Purified and third-party-tested shilajit is safe for most healthy adults when used at a sensible dose. The main safety issue is product quality. Raw or poorly controlled shilajit may contain heavy metals, microorganisms, and fungal contaminants, whereas a trustworthy finished product should provide batch-specific laboratory results.

Choose a transparent brand, follow the serving directions, and stop if you experience a concerning reaction. With shilajit, the safest product is not necessarily the one that looks the most rugged or traditional. It is the one that can prove what is inside the jar.
