Shilajit is often praised for its traditional use and functional properties, but like with any supplement, there may be potential side effects — especially if taken in excessive amounts or from low-quality sources. This article outlines the most common side effects of Shilajit and how to avoid them with informed and responsible use.
While scientific studies have explored the potential of purified Shilajit extract in supporting various functions, researchers also point out that certain precautions are necessary, particularly in vulnerable groups (1).
What Are the Side Effects of Shilajit?
The most commonly reported side effects include mild digestive issues such as nausea, upset stomach, or loose stool. These usually occur when the dosage is too high or when the product has not been properly purified. Gradually increasing the dosage and following recommended instructions can help reduce this risk (2).
Some users also mention feeling slightly tired or dizzy in the first few days as the body adjusts to the supplement (3).
Shilajit and Allergic Reactions: What You Should Know
Although Shilajit is a naturally occurring substance, rare allergic reactions such as itching, skin rashes, or slight swelling have been reported. People with known sensitivities to natural resins, minerals, or plant compounds should exercise caution. If any allergic symptoms appear, the supplement should be discontinued, and medical advice sought (4).
Starting with a small dose or consulting a healthcare provider may be a good way to assess personal tolerance before long-term use (5).
Shilajit and Iron: Why the Content Matters
Shilajit naturally contains iron, which is a beneficial trace mineral for many individuals. However, people with certain genetic conditions like hemochromatosis — a disorder that causes excess iron accumulation — should avoid supplements high in iron, including Shilajit. Too much iron can potentially contribute to symptoms such as joint pain, fatigue, or organ-related stress (6).
It is advisable for individuals with iron regulation issues to speak to their doctor before using Shilajit.
Contaminated Shilajit: The Risk of Poor-Quality Products
One of the biggest risks associated with Shilajit is product quality. If Shilajit is not properly purified, it may contain heavy metals, toxins, or other unwanted compounds. Poor-quality products may do more harm than good.
Research shows that purified, lab-tested Shilajit can be safely used as a supplement. When choosing a product, always look for third-party test results, certificates of analysis, and transparent sourcing practices (2).
Shilajit and Medication: Potential Interactions
Shilajit may interact with certain types of medications, especially those related to blood sugar, blood pressure, or iron metabolism. These interactions may alter the way medications work or increase their intensity (4).
If you are taking prescribed medication, it's important to consult your doctor before using Shilajit to ensure compatibility and safety (5).
Is Shilajit Safe During Pregnancy and Breastfeeding?
There is currently not enough research to confirm the safety of Shilajit during pregnancy or breastfeeding. For this reason, it is generally not recommended for use during these stages without explicit medical guidance (6).
Certain components in Shilajit may influence hormonal pathways, so extra care should be taken during hormonally sensitive periods such as pregnancy or lactation.
Shilajit and Safe Use: How to Minimize Side Effects
Shilajit can be part of a daily routine when used in moderation and with care. Choosing a high-quality product and starting with a low dose is the best way to reduce the risk of unwanted effects. Always read labels carefully and seek medical advice if you have any existing health conditions or concerns.
