Shilajit During Pregnancy: Is It Safe?

Pregnancy can make ordinary tiredness feel like your body has quietly switched to low-power mode. As a result, the promises of Shilajit to boost energy, minerals, and vitality sound very attractive.

There are no well-designed human studies that demonstrate whether Shilajit is safe for a pregnant woman. Even a purified product may contain a complex and variable mixture of minerals and organic compounds that has not been adequately studied during pregnancy.

Our practical advice is that you avoid Shilajit if you are pregnant, breastfeeding, or actively trying to conceive. The only exception to this rule is if your doctor specifically recommends it.

Why Is Shilajit Not Recommended During Pregnancy?

Shilajit is a resin-like material that gets formed when decomposed organic matter mixes with minerals inside mountain rock.

Its exact composition can vary based on:

• Where it was collected.
• How it was processed.
• The purification method.
• Environmental contamination.
• The final product formulation.

Pregnancy changes the safety equation because substances that are taken by the mother may reach the fetus through the placenta. A supplement does not need to cause obvious symptoms in the mother to create issues for fetal development.

The NIH pregnancy dietary supplement guide states that nutrient requirements change during pregnancy and that safety evidence for many botanical ingredients is limited.

Shilajit is not an essential pregnancy nutrient, and there is no established pregnancy dose, proven pregnancy benefit, or clinical evidence that demonstrates fetal exposure is safe.

No Human Pregnancy Trials

Most Shilajit studies involve healthy men, physically active adults, postmenopausal women, and laboratory animals.

These studies have examined possible effects on:

• Physical performance.
• Testosterone.
• Sperm quality.
• Collagen synthesis.
• Bone density.
• Oxidative stress.

What these studies don’t tell us is what happens to fetal development after the intake of Shilajit. One older study in pregnant mice did not find significant differences in litter size, placental weight, embryo weight, and embryo resorption after short-term Shilajit exposure.

The result is mildly reassuring. However, it’s not nearly enough to confidently conclude that Shilajit is safe in pregnant humans. Remember, animal pregnancies differ from human pregnancies, the study was small, and the tested material may not resemble modern products.

Heavy-Metal Contamination is the Biggest Concern

Shilajit forms in a mineral-rich environment, so it can naturally contain metals.

The Department of Defense’s Operation Supplement Safety overview notes that Shilajit may contain lead, arsenic, mercury, and cadmium. The amounts vary significantly between products.

A 2025 analysis also detected thallium in raw shilajit and several commercially available supplements. Some finished products contained more thallium than the untreated source material.

Heavy metals are very concerning during pregnancy because some can cross the placenta.

The Centers for Disease Control and Prevention (CDC) reports that prenatal lead exposure can increase the risks of:

• Impaired fetal neurodevelopment.
• Reduced growth.
• Premature birth.
• Miscarriage
• Low birth weight.
• Developmental problems.

In one CDC investigation, several pregnant women developed lead poisoning after they used contaminated Ayurvedic products. Some products also contained arsenic or mercury.

Does Purification Make Shilajit Safe for Pregnancy?

Purification reduces debris, microorganisms, and certain contaminants. Third-party testing can also confirm that a batch meets established limits for selected metals.

That makes tested shilajit a better choice for nonpregnant adults than raw resin. It does not prove pregnancy safety.

A laboratory report can show that a batch contains less than a specified amount of lead or arsenic. However, it cannot show that the mixture has been studied during implantation, organ formation, placental development, or fetal growth.

Some testing panels also focus on lead, mercury, arsenic, and cadmium but do not measure less commonly screened metals (e.g., thallium).

In other words, purification addresses one concern (contamination), but not the larger absence of reproductive safety data.

What About Shilajit Before Pregnancy?

Shilajit has been studied for male fertility, but that does not make it a proven female preconception supplement.

Laboratory research suggests that it may affect reproductive biology. Human research has also found hormonal changes in men taking purified Shilajit. Because the effects on ovulation, implantation, early embryos, and female reproductive hormones remain unclear, the safest approach is to stop Shilajit when actively trying to conceive.

The American College of Obstetricians and Gynecologists (ACOG) recommends reviewing herbal products and nutritional supplements during pre-pregnancy counselling.

Anyone who uses Shilajit for energy or general wellness before conception should discuss when to discontinue it with their clinician.

Is Shilajit Safe While Breastfeeding?

Shilajit is also best avoided during breastfeeding. There are no reliable studies that tell us:

• Whether its active compounds enter breast milk.
• What dose a nursing baby might receive.
• Whether contaminants transfer through milk.
• How an infant would metabolize its complex ingredients.

Lead can pass from maternal blood into breast milk, and the CDC recommends medical assessment when breastfeeding women may have been exposed to lead.

A newborn has a much smaller body and developing kidneys, liver, and nervous system. Consequently, unnecessary exposure to some supplements can be dangerous.

What Should You Do If You Took Shilajit Before Knowing You Were Pregnant?

An accidental dose or short period of use does not mean that harm has occurred. Risk depends on the product, dose, duration, contamination level, and stage of pregnancy.

Take these practical steps:

• Stop taking the product.
• Keep the packaging, ingredient label, batch number, and any Certificate of Analysis.
• Tell your obstetric clinician what you took, how much, and for how long.
• Mention whether the product was raw, imported, homemade, or purchased.

The CDC recommends considering lead testing during pregnancy when someone uses imported traditional remedies or products that may contain heavy metals.

FAQs About Shilajit and Pregnancy

Conclusion

Shilajit should not be taken during pregnancy, trying to conceive, or during breastfeeding.

The recommendation is based mainly on missing human safety data and the potential for heavy-metal or microbial contamination. It’s not guaranteed that every exposure causes harm.

Purification and third-party testing improve product quality for nonpregnant adults, but they cannot answer questions about fetal development or infant exposure.

Anyone who has already taken shilajit should stop, keep the product information, and speak with their prenatal clinician. Pregnancy is one period when “probably fine” is not a strong enough standard for a nonessential supplement.
