What Exactly Does Milk Thistle Extract Do?

Milk thistle extract helps keep normal liver function by backing detox pathways and by acting as an antioxidant, aiding cellular protection against oxidative stress.

Dr. Saller of the University of Munich found that silymarin supports hepatic health and the body’s natural detoxification system, aligning with EFSA-style mechanisms for liver support.
