Who should not take Shilajit? Precautions and Safety
Before starting a course of treatment, it is essential to be aware of the contraindications of shilajit for your safety. Although this mountain treasure is natural, it is crucial to understand the contraindications of shilajit before beginning a course of treatment. Consumer safety remains our top priority. This potent supplement is not suitable for everyone and requires careful consideration based on your individual health profile.

Shilajit is an ancient resin used in Ayurvedic medicine. Its quality varies greatly depending on its origin and purification process.
We want to clarify our objective: to identify at-risk profiles, outline the main risks , and offer a checklist for purchasing goods in France. The central theme remains security and traceability.
Warning: This supplement is active. It may interact with treatments for diabetes, high blood pressure, or blood thinning medications. We will explain how to identify a purified product and what tests to request.
Key points
- Pregnancy requires a strict precautionary approach.
- Variable quality: major risk = heavy metals.
- Certificates and analyses are essential.
- Possible interactions with chronic medications.
- Our guide offers a clear buying checklist.
Shilajit: what it really is, between Ayurvedic medicine and a modern supplement
We define it as a dark substance harvested from high mountain ranges. It is a natural resin, resulting from the slow transformation of organic matter mixed with mineral components.

Origin: It is often found in the Himalayas, the Altai Mountains, and the Caucasus. Its formation is geological: organic matter is compressed and seeps through the rocks. This process explains its black color and sticky texture.
Synthetic composition
The composition mixes organic acids and more than 80 trace elements. It notably contains fulvic acid (often the predominant component), humic acid, dibenzopyrones, as well as minerals such as iron , zinc and magnesium .
"A high mineral density can be beneficial, but requires rigorous purification."

"A high mineral density can be beneficial, but requires rigorous purification."
Why the composition requires caution
A high content of fulvic acid and minerals is beneficial for nutritional value. However, it becomes a risk if the resin also concentrates contaminants from the rocks.
| Element | Role | Risk related to concentration |
|---|---|---|
| Fulvic acid | Improves nutrient bioavailability | Surcharge if not standardized |
| Iron | Essential trace element | Possible accumulation in some subjects |
| Minerals (zinc, magnesium) | Enzymatic supports | Imbalances if there is excess |
- Practical conclusion: "natural" does not guarantee "clean".
- The higher the concentration of active ingredients, the more critical traceability and purification become.
Why caution is necessary: scientific data is still limited
Despite a long history of use, clinical research remains fragmented in 2026. We see sporadic studies on energy, fatigue and performance, but the quality of the trials and the sample sizes are often insufficient.
Tradition ≠ proof. The benefits of shilajit are reported in traditional medicine, but their generalization requires standardized and replicable trials.

Variability in quality: the key risk
The same trade name masks very different chemical products depending on their origin and purification.
- As a result, asset and contaminant profiles vary greatly.
- Without standardization, the effects observed in one study do not automatically apply to another product.
"The more at-risk your situation is (pregnancy, chronic illness, treatments), the more important it is to seek medical advice."
We are thus preparing the next section, devoted to heavy metals, because this is where the variability in quality has the most concrete impact on consumption and safety.
Heavy metals: the main danger of an unpurified shilajit
We observe that the most concrete threat comes from heavy metals. The resin adheres to rocks. It can therefore concentrate metals if purification is insufficient or if the extraction area is polluted.

Which metals and why are they a concern?
Lead , arsenic , and mercury are the most frequently cited. They accumulate gradually in the body.
| Element | Origin | Main effect |
|---|---|---|
| Lead | Rocks, contaminated soil | Nervous system, fetal development |
| Arsenic | Water and geological layers | Liver, kidneys, long-term cancer |
| Mercury | Minerals and local pollution | Neuropathies, cognitive disorders |
Field data and consequences
A 2018 study from Delhi University analyzed 20 commercially available samples. 60% exceeded the standards for lead. 30% had high levels of arsenic.
Consequences: damage to the liver, kidneys, and nervous system. The effect is cumulative with repeated exposure.
"Natural" does not exclude contamination; purification changes everything.
- Good practice: require a laboratory certificate for purified shilajit.
- A poor quality product can pose a real danger to health.
Who should not take shilajit: risk profiles and contraindications
Caution is advised: some individuals are more vulnerable to contaminants and interactions. Before consuming shilajit, check if you fall into one of the categories below.

Pregnant women
Precautionary principle. Clinical data are insufficient, and the fetus is sensitive to heavy metals. This supplement should be avoided during pregnancy until reliable medical advice is available.
Breastfeeding women
There is a lack of specific studies on breastfeeding. We recommend caution and medical consultation before taking any supplements.
Children and teenagers
Avoid consuming shilajit if you are under 18 years old. The benefit/risk ratio has not been established for this age group.
People with chronic illnesses
Liver, kidney, or heart problems require medical advice . Drug interactions and altered elimination may increase the risks.
Hormonal imbalances and iron overload
High mineral content can worsen hormonal imbalances or iron overload. Request a blood test before taking any supplements.
"If you check one of these boxes, prioritize safety above any supplements."
| Profile | Reason | Recommendation |
|---|---|---|
| Pregnancy | Fetal vulnerability, insufficient data | Abstention + medical advice |
| Breastfeeding | Lack of studies | Consultation before taking |
| Under 18 | Lack of safety assessment | Avoid |
| Liver / Kidneys / Heart | Altered elimination, interactions | Mandatory medical follow-up |
Shilajit and pregnancy: what pregnant women absolutely need to know
During pregnancy, the use of concentrated supplements raises serious safety concerns. We adopt the precautionary principle.

What are the contraindications of Shilajit?
Lack of robust clinical data
The available trials are limited and heterogeneous. No large-scale randomized trial has been able to confirm safety during pregnancy.
Conclusion: The absence of evidence does not guarantee safety. We recommend refraining from use without medical advice.
Fetal toxicity and sensitivity to pollutants
The fetus is particularly vulnerable to contaminants. Even low levels of exposure can affect neurological development and long-term health .
The invisible risk: unpurified products
An unpurified product may contain heavy metals such as lead or arsenic . These contaminants are undetectable to the naked eye.
Two identical batches can have very different profiles depending on their origin and purification. This is where the risk lies.
Even with a tested product: medical advice is still required
Tested brands (e.g., Altai Origin) offer controls that reduce risk. They do not eliminate scientific uncertainty.
We insist: obtain medical advice before taking any supplement during pregnancy. In practice, it is not recommended to test a supplement during the prenatal period.
"During pregnancy, caution must prevail: future health is not a testing ground."
Drug interactions: when shilajit can become risky
Natural supplements can alter biological parameters and create unexpected interactions.

The main contraindications of Shilajit to know
We remind you: an active product can affect blood sugar, blood pressure, and the effectiveness of anticoagulants. This creates a real risk when used in combination with other medications.
Diabetes
If a supplement lowers or raises blood sugar, it can amplify the effect of an antidiabetic medication. The result: hypoglycemia or imbalance. People undergoing treatment should seek advice and monitor their blood sugar regularly.
Hypertension
An unexpected change in blood pressure complicates the adjustment of antihypertensive medications. The goal is stability, not experimentation. Before taking any medication, seek medical advice .
Anticoagulants
Anticoagulants may have their effectiveness altered. This increases the risk of bleeding or thrombosis depending on the direction of the interaction. Avoid combining them without strict monitoring.
"Do not start or stop treatment on your own: consult a doctor, get tested, and then monitor."
Simple protocol: do not start alone, seek advice, schedule checks (blood sugar, blood pressure, INR) if the professional authorizes it.
Possible side effects: how to recognize them and what to do
Vigilance regarding clinical signs after further use remains essential. We list the most frequent side effects here so you know what to watch for from the very first use.

Digestive problems
Symptoms: nausea, abdominal cramps, diarrhea. These digestive problems are often linked to an overdose or individual sensitivity.
They usually improve when the product is stopped. If symptoms persist for more than 48 hours, consult a doctor to assess hydration and electrolyte balance.
Allergic reactions
Skin symptoms: redness, itching, rash. Action to take: stop immediately and monitor the situation.
If you experience difficulty breathing or facial swelling, seek immediate medical attention. Prompt medical advice can prevent complications.
Reported cases of liver toxicity
Serious cases have been described, including acute hepatitis after two weeks of consumption, according to the Journal of Clinical and Experimental Hepatology.
Action plan: Stop taking the medication immediately if you experience severe abdominal pain, jaundice, or extreme fatigue, and seek medical advice. Liver function tests are necessary if symptoms suggest liver damage.
"Natural" does not exclude a real risk; monitoring remains essential for health.
How to choose a purified and safe shilajit: purchasing criteria in France
Product selection should prioritize transparency of analyses and purification method.

Purification: Opt for gentle water purification, as explained on the label. A mechanical and aqueous method reduces the risk of altering the active ingredients while limiting contaminants.
Laboratory analyses: require certificates for heavy metals (lead, arsenic, mercury). We recommend recent reports signed by an independent laboratory based in Europe.
Standardization: choose a product that lists the fulvic acid content and other active ingredients. Transparency regarding concentration makes it easier to compare products.
Form: Resin adheres to tradition but makes dosing less intuitive. Powder and capsules offer convenient precision for daily use.
Warning signs
- Vague origin or "miracle" promises.
- No laboratory reports.
- Price incompatible with strict controls.
Altai Origin quality reduces risks through public testing; however, this does not exempt you from seeking medical advice for pregnancy.
Concrete examples: favoring standardized extracts like PrimaVie® or tested products such as Altai Origin. In France, these guidelines improve safety and confidence when purchasing.
Dosage and best practices to limit risks
Before any supplementation, let's establish a simple rule: start low, observe, then adjust. This method protects health and allows for the assessment of tolerance.

Typical dose: 300 to 500 mg/day
Practical guideline: aim for 300–500 mg/day. This common dosage offers a balance between effectiveness and safety.
More is not better : exceeding this mainly increases the likelihood of side effects, particularly digestive problems.
Treatment duration: three to six weeks, then a break
We recommend courses of treatment lasting 3 to 6 weeks. Then, take a break to observe the progress.
Regularity is better than intensity. Moderate consumption reduces risks and makes it easier to assess effects.
- Start low and follow the dosage instructions.
- Monitor for side effects: digestion, fatigue, skin reactions.
- Traceability : choose a product with analyses and quality control.
"If a symptom appears or if you are undergoing treatment, seek medical advice before continuing."
If in doubt, consult a doctor. Our approach remains simple: reasonable dosage, limited treatment, and attention to clinical signs for safe use.
Conclusion
The summary is simple: potential interest and benefits go back several centuries, but safety remains the priority.
Major risk: a poor quality product can concentrate heavy metals and cause adverse effects.
Choose a formula that has been tested, standardized for fulvic acid , and accompanied by analyses. A controlled brand reduces the risk but does not replace medical advice .
Protect pregnant or breastfeeding women, minors, and people with chronic illnesses in particular. If symptoms appear, stop use and consult a doctor.
Our promise : to link ancestral practices with modern criteria of quality, transparency and prudence, without excessive promises.
