Swanson Milk Thistle Phytosome is our most effective milk thistle supplement for effective liver support! Nature's premier liver tonic, milk thistle delivers a flavonoid complex known as silymarin, which has unique protective benefits for liver tissues. Recently, researchers have identified one constituent of silymarin, silibin, as the most biologically active. The problem is, silibin is not readily absorbed by the body. That's where Siliphos® comes in. This advanced milk thistle supplement uses Phytosome technology to bind silibin to phospholipids for enhanced bioavailability.

  1. What is milk thistle?
    Milk thistle (Silybum marianum) is a flowering herb that has been used for centuries to support liver health. Its seeds contain naturally occurring compounds called flavonolignans, collectively known as silymarin, which have been studied for their antioxidant properties.
  2. What is Siliphos®?
    Siliphos®—as found in Swanson Milk Thistle Advanced Enhanced Absorption—is a patented complex of milk thistle extract (silybin) and phosphatidylcholine. Unlike standard milk thistle extracts, Siliphos binds silybin—the primary active component of silymarin—to phosphatidylcholine, a phospholipid found in cell membranes. This phytosome® delivery technology has been shown to improve the absorption and bioavailability of silybin compared with conventional milk thistle extracts. Siliphos has been studied for its ability to provide antioxidant support and support healthy liver function and the body's natural detoxification processes.
  3. What's the difference between silybin and silymarin?
    Silymarin is the natural extract obtained from milk thistle seeds and contains a group of antioxidant compounds called flavonolignans. Silybin is the primary and most biologically active component of silymarin and has been the focus of much of the clinical research on milk thistle.
  4. How does milk thistle support liver health and detoxification?
    The liver naturally processes and eliminates metabolic byproducts through its normal detoxification pathways. Milk thistle provides antioxidant support that helps protect liver cells from oxidative stress while supporting healthy liver function and the body's natural detoxification processes.
  5. Can I take milk thistle every day?
    Yes. Milk thistle is commonly used as part of a daily wellness routine to support liver health. Follow the recommended serving size on the product label and consult your healthcare provider if you have questions about long-term use.
  6. Is Swanson Swanson Milk Thistle Advanced Enhanced Absorption suitable for special diets?
    Yes. Swanson Swanson Milk Thistle Advanced Enhanced Absorption is non-GMO, gluten free, and dairy free. However, it is not suitable for vegan or vegetarian diets because the capsule contains gelatin.
