Milk thistle powder comes from the Silybum marianum plant and supplies silymarin compounds. People stir it into water, juice, or smoothies and often take it alongside meals to improve absorption. They use it for liver support and digestive comfort, though the evidence behind these uses is not consistent.
This powder can cause mild stomach upset. Because it may shift how the liver processes certain drugs, it can interact with some statins, antifungal medications, and blood thinners. Anyone who has a liver condition or takes prescription medicines should talk to a healthcare professional before using milk thistle.
