1. Promotes Liver Health: Milk Thistle contains a compound called silymarin, which has been shown to have protective and regenerative effects on the liver. It can help to prevent liver damage and improve liver function, making it a great supplement for those who have liver conditions or want to support their overall liver health.
2. Supports Detoxification: Milk Thistle has been used for centuries as a natural detoxifier, helping to rid the body of toxins and impurities. It works by stimulating the production of bile, which helps to flush out harmful substances from the liver and digestive system. Regular use of Milk Thistle can help to support the body's natural detoxification processes and keep the liver functioning properly.

The Active Ingredient Is: Milk Thistle (Silymarin)

Milk Thistle, a herb-based extract, contains the compound silymarin which acts as the main active constituent with antioxidant benefits. This form is a standardised plant extract aimed at helping normal liver function and cellular protection processes. It is shown to interact with liver cells to support normal physiology.

This extract is derived from Milk Thistle and gives the silymarin group as its primary active component. Other constituents may be present in the extract, which help support the main role of the active ingredient in keeping normal liver function and metabolic health.

What Does Milk Thistle (Silymarin) Do?

Milk Thistle helps shield cell membranes and support normal oxidative stress responses, as described in mechanistic reviews of silymarin’s actions. This lines up with its intended role in supporting liver health in line with everyday physiology and dietary guidance.

Additionally, silymarin is known for antioxidant and anti-inflammatory properties that contribute to maintaining normal liver cell integrity and function in various contexts of metabolic health.
