    Overview

    Dosage information

    Milk thistle supplements are sold in the form of capsules, tablets, and tinctures and also exist as intravenous solutions (only available in hospital settings).

    The recommended daily dosage of any given milk thistle supplement depends on both the treatment purpose and the supplement’s silymarin content.

    When silymarin is used for hepatoprotection, the recommended daily dosage typically falls in the range of 420 mg to 600 mg of silymarin per day, usually taken in three split doses.[1][2]
