As of Nov 2026, Unbox Health has lab tested and rated 1 products in the Milk Thistle Supplements category.
We buy every product from the open market, with no brand involvement. Every product is tested at up to 3 NABL-accredited labs. Products are then rated D to A+, based on the following dimensions: their label accuracy, their toxicity and their nutritional profile (in the case of food products). All lab reports are published.
For Milk Thistle Supplements, Unbox Health’s lab tests check Milk Thistle against the label claim, any other active ingredients claimed on the label, and heavy metals (lead, arsenic, cadmium and mercury).

Milk thistle supplements contain silymarin, a plant compound extracted from milk thistle seeds, mainly marketed for liver support. Some studies suggest silymarin may help support liver cell function and is associated with protective effects against certain toxins, though it is not a cure for liver disease. ICMR-NIN has not issued guidelines on milk thistle. Anyone with a diagnosed liver condition should use it alongside medical treatment, not instead of it.
Milk thistle supplements are generally considered safe for most healthy adults at commonly used doses, though mild digestive upset such as bloating or loose stools has been reported in some users. Long-term daily-use evidence in the Indian population is limited. Pregnant or breastfeeding women, people with hormone-sensitive conditions such as breast or uterine conditions, and those on liver medication should consult a doctor before daily use.
Most milk thistle supplements sold in India use vegetarian capsule shells made from HPMC (cellulose) rather than gelatin, though some imported brands still use gelatin-based capsules sourced from animal collagen. The extract itself, silymarin, is plant-derived and vegetarian by nature. Always check the label for capsule shell material if this matters to you. Verify the declared capsule type against Unbox Health's independently tested label-accuracy data before buying.
No, milk thistle supplements cannot cure fatty liver disease. Some clinical research suggests silymarin may help support liver enzyme levels, but current evidence does not establish it as a treatment or cure for the condition. Fatty liver disease requires medical diagnosis and management through diet, weight control, and physician-guided care. Milk thistle may be used only as a supportive addition, never as a replacement for treatment.
Milk thistle is the plant Silybum marianum; silymarin is the group of active flavonoid compounds extracted from its seeds. Most supplements labeled "milk thistle" are standardized extracts measured by silymarin content, commonly 70-80 percent. This percentage matters more than milk thistle weight on the label, since it determines actual active compound intake. Unbox Health's lab tests verify whether a product's declared silymarin content matches what is present.
ICMR-NIN has not established a specific dosage for milk thistle or silymarin, as it is a herbal supplement, not an essential nutrient. International studies have commonly used 140 mg of silymarin two to three times daily, standardized to 70-80 percent content. As practical guidance, follow the manufacturer's label dose and do not exceed it. Verify the declared silymarin content against Unbox Health's independently tested lab results before choosing a product.
Milk thistle supplements are generally well tolerated, but some users report mild digestive symptoms such as bloating, nausea, or loose stools. Rare allergic reactions can occur in people allergic to plants in the daisy family, such as ragweed. Silymarin may also have mild estrogenic activity, so it is not recommended for those with hormone-sensitive conditions such as breast cancer, uterine fibroids, or endometriosis without medical advice.
Milk thistle tablets can be taken at any time of day, since there is no established evidence that timing significantly affects absorption. Many people take it with a meal, such as breakfast or dinner, to reduce mild stomach discomfort some users experience on an empty stomach. If taking it two or three times a day, spacing doses evenly, such as morning and evening, helps maintain steadier levels through the day.
Yes, milk thistle can interact with certain medications since silymarin affects liver enzymes involved in drug metabolism. It may alter blood levels of some diabetes medications, blood thinners, and drugs metabolized by the liver, such as certain statins and hormone therapies. People on regular prescription medication, especially for diabetes, blood clotting, or hormone-related conditions, should consult their doctor before adding milk thistle to avoid unexpected interactions.
There is no single "best" milk thistle brand; quality depends on whether declared silymarin content matches what a product actually contains, and this varies between manufacturers. Compare products using independent, lab-tested data rather than marketing claims. Unbox Health buys milk thistle supplements from the open market, tests them at NABL-accredited labs, and rates brands on label accuracy to show which ones deliver their claimed silymarin content.
