Silybum marianum
Free herbal dosage calculator — adult & child doses by weight.
Milk thistle has been used for over 2,000 years as a natural remedy for liver and gallbladder disorders. Its active compound complex, silymarin, has been extensively studied for hepatoprotective effects. It is one of the few herbs with strong clinical evidence for liver support and protection.
Milk Thistle (Silybum marianum) is the most researched hepatoprotective herb, with silymarin extract showing Level A evidence for liver protection against toxins.
Silymarin stabilizes hepatocyte membranes, stimulates protein synthesis and hepatocyte regeneration, and inhibits NF-κB inflammatory pathway. Phosphatidylcholine complexes (silipide) improve bioavailability 3-5x.

Milk thistle works primarily through silymarin, a flavonoid complex that stabilizes cell membranes and prevents toxins from entering liver cells. It acts as a potent antioxidant, reducing oxidative stress and inflammation while stimulating protein synthesis for liver cell regeneration. Evidence Level A supports its mechanism of blocking toxin binding sites on hepatocytes.
Yes, milk thistle may interact with medications metabolized by the liver's cytochrome P450 enzyme system. While it generally has a low potential for interactions, it can affect how the body processes certain drugs, such as statins and blood thinners. It may also enhance the effects of antidiabetic medications, potentially causing hypoglycemia.
The standard adult dosage for liver support is 200-400mg of silymarin (standardized to 70-80% potency) taken two to three times daily. This dosing range is supported by Level A evidence for hepatoprotective effects. Because silymarin has low bioavailability, divided doses throughout the day are recommended to maintain steady blood levels.
Milk thistle is considered unsafe during pregnancy due to insufficient safety data and potential uterine effects. While it has been traditionally used to increase breast milk supply, clinical evidence is lacking. Women who are pregnant, nursing, or trying to conceive should avoid this supplement unless specifically directed by a qualified healthcare provider.
Milk thistle is primarily used for liver protection and treating conditions like cirrhosis, hepatitis, and fatty liver disease (Evidence Level A). It also supports gallbladder health and helps regulate blood sugar levels. Historically, intravenous silibinin has been used as an emergency antidote for death cap mushroom poisoning due to its potent hepatoprotective properties.
Individuals with allergies to plants in the Asteraceae family (ragweed, daisies, marigolds) should avoid milk thistle due to cross-reactivity. Those with hormone-sensitive conditions should exercise caution as silymarin may have weak estrogenic effects. People taking antidiabetic medications should monitor blood sugar closely to avoid hypoglycemia.
