  • Milk thistle nutrition for all-natural liver nourishment

  • Effective and economical support

  • Each capsule delivers 500 mg of milk thistle

Swanson Premium Milk Thistle is the ultimate in liver health. Silymarin, a powerful antioxidant flavonoid, contains specific protective benefits for liver tissues, making milk thistle a premier liver tonic. Our convenient capsules deliver 500 mg of milk thistle nutrition that won't put a dent in your pocketbook.


Q: How much silymarin is present in each 500 mg milk thistle capsule?
A: This is a full-spectrum milk thistle product, meaning that it is not standardized to provide a set amount of any active compounds like silymarin. Silymarin naturally occurs in milk thistle, so it will be present, but the amount will vary from pill to pill.

Rated 4 out of 5 by Milk Thistle with Ease I have practiced herbcrafting for some years and I find that having milk thistle in capsule form is sometimes easier for a me, when I am doing a mild cleanse. The Swanson product allows me that ease and it is a quality herbal product February 7, 2014
