Rasayana or rejuvenator in Ayurvedic remedy, shilajit is the best supplement this traditional system recommends for overall wellness. Among many systems of the body it works its magic on, the excretory system is also included- where the kidney plays the role of the primary organ.
But when it comes to kidney stones, does shilajit really play the role of a healer/ helper or not? Here, we will explore whether it's okay to use shilajit in the context of kidney stones or if caution is needed while using it for this specific purpose.
By the end of the article, you will be able to make an informed decision on whether to use it or not for kidney stones and understand the precautions to make a safe use of shilajit.
Summary at a Glance
For most healthy, well hydrated adults taking a normal dose, shilajit is not considered a direct cause of kidney stones. It does contain oxalates and a broad mineral load. The clearer risks come from unpurified or untested product, low fluid intake, and existing kidney conditions. Shilajit is not a treatment for kidney stones.
Understanding Kidney Stones
Kidneys are responsible for filtering blood, to make it pure. The waste products they are supposed to filter out especially salt and minerals, if not fully eliminated, can cause kidney stones. In general, around one in ten individuals is known to suffer from kidney stone once in their lifetime.
The early treatment can be effective in easing the healing process, causing stones to pass out early without causing many health complications. But if it's not cured on time, the patient has to suffer from extreme pain and even greater issues like a blockage of urine flow can show up.
Common Types and How Do They Form
An optimally functioning kidney results in a balance of salt, minerals and water inside the body. If only a small disturbance occurs on this, then salt and minerals would deposit on the kidney parts, including the tubules.
The main types:
- Calcium oxalate stones. The most common by far. They form when calcium binds with oxalate in the urine.
- Uric acid stones. More common with high animal-protein diets and low fluid intake.
- Others: calcium phosphate, struvite, and cystine stones.
What actually drives stone formation. The strongest and most consistent factor in the research is not any single food. It is concentrated urine, usually from not drinking enough fluid. Low citrate, high oxalate load, and certain medical conditions raise the risk too. This matters, because it tells you where the real levers are.
Does shilajit cause kidney stones? A closer look
Shilajit contains oxalates. This is true. Oxalate is one half of the most common stone type, so it is reasonable to ask whether adding an oxalate-containing supplement raises your risk. For a healthy person drinking enough water, the oxalate in a normal shilajit serving is small compared with everyday high-oxalate foods like spinach, nuts, and tea. For someone who already forms calcium oxalate stones, any added oxalate is worth discussing with a doctor.
Shilajit is mineral dense. Being mineral rich is the whole point of shilajit. It contains 85+ minerals, with fulvic acid as one component. For transparency, Everest Shilajit publishes the fulvic acid content per serving in the resin, liquid drops, dry drops and gummies. You can see the full breakdown on the third-party lab report and the trace minerals page. Being mineral rich does not automatically mean stone forming. What matters is dose, hydration, and your kidney history.
The diuretic point. Shilajit is sometimes described as having a mild diuretic effect, meaning it can increase urine output. On its own that is neither protective nor harmful for stones. What decides the outcome is fluid. If you are well hydrated, more urine flow simply keeps things dilute. If you are dehydrated, any diuretic effect is a reason to be more careful, not less. See the dosage and usage guidance before you start.
The real risk that deserves the most attention: purity
Shilajit is scraped from rock at high altitude. In its raw, unpurified state it can carry heavy metals such as lead, arsenic, mercury, and cadmium, along with soil and microbial contaminants. Peer-reviewed analyses have found heavy metals above safe limits in some herbal and Ayurvedic products, and regulators in several countries have issued consumer warnings about contaminated Ayurvedic preparations. Heavy metals are hard on the kidneys. That is a far more concrete kidney risk than the oxalate question.
The word "purified" on a label means nothing on its own. There is no standard definition of it. The only thing that tells you what is actually in a product is a current, independent lab report that shows heavy metal levels within accepted limits.
This is why Everest Shilajit is third-party lab tested every batch, with results published on the Lab Report page. Third-party testing costs roughly two thousand dollars per batch. We do it because it is the only honest way to answer the purity question. Whatever brand you choose, ask for the certificate of analysis. If a seller cannot show you one, that is your answer.
What the research actually shows, and what it does not
You will see it claimed that shilajit dissolves or prevents kidney stones. That claim usually points to one source, and it is worth understanding what that source actually is.
In-vitro study, explained honestly. A study in the Indonesian Journal of Urology took a single kidney stone, suspended it in a water-based shilajit extract in a test tube, and left it for 72 hours. The stone lost a small amount of weight. That is the entire study.
Why this does not mean shilajit treats stones. A stone sitting in liquid in a test tube is nothing like a stone inside a working kidney, surrounded by living tissue, blood flow, and constantly changing urine chemistry. A test-tube result cannot predict what happens in a human body. There are also some early animal studies on kidney-protection markers, but human clinical trials are lacking. So the honest position is simple: current evidence does not support claims that shilajit treats, prevents, or dissolves kidney stones in people.
Who should be cautious or avoid shilajit
A medical conversation before using shilajit is advisable for anyone who:
- Has chronic kidney disease or reduced kidney function.
- Has a history of kidney stones.
- Is on dialysis.
- Takes diuretics, blood pressure medication, or other prescriptions affecting the kidneys.
- Is pregnant or breastfeeding.
Long-term daily use without any medical check-in is also not advisable, especially at higher doses.
How to lower your risk if you choose to use shilajit
-
Adequate water intake. This is the single most evidence-backed step for reducing stone risk, with or without shilajit.
-
A normal serving. More is not better. The dosage guidance covers typical amounts.
-
Only lab-tested product. The certificate of analysis shows heavy metal levels.
-
Never raw or folk-processed shilajit. Unpurified material is where the real danger sits.
-
A doctor's input for anyone with a kidney history or on related medication.

Myth vs fact
| Myth | Fact |
|---|---|
| Shilajit's minerals directly cause kidney stones | For healthy, well hydrated adults taking a normal dose, shilajit is not considered a direct cause of kidney stones. Purity, Dosage, hydration and your kidney history matter more. |
| Shilajit dissolves kidney stones | One small in vitro test tube study showed slight stone weight loss. There is no reliable human evidence that shilajit dissolves kidney stones inside the body. |
| "Purified" on the label means it is safe | "Purified" does not have one standard meaning. A current third party laboratory report is needed to show what is actually inside the product. |
| All shilajit is basically the same | Unpurified or untested shilajit may contain heavy metals or other contaminants that can place stress on the kidneys. Independent testing is an important difference. |
| If a little is good, more is better | Higher doses are not necessarily safer or more effective. Following the recommended serving size and staying properly hydrated is the more sensible approach. |
| Shilajit can replace medical care for kidney stones | It cannot. Kidney stones require proper medical evaluation, diagnosis and treatment from a qualified healthcare professional. |
Conclusion
Shilajit does not have a strong, evidence-based link to causing kidney stones in healthy, hydrated adults at normal doses. It is not a cure or preventive for stones either. The concern that deserves the most attention is purity, followed by hydration and individual kidney history. The sensible approach is lab-tested product, adequate water, a normal dose, and a doctor's input for anyone with a kidney condition.
