Things You Need to Know  About NutraExtract™ Milk Thistle Extract

Is Silybin the same as Silymarin?

Silybin is the most important component of silymarin, it is a plant extract extracted from the seed of a compositae medicinal plant called milk thistle.

Silybin is yellow powder or crystalline powder with bitter taste.  The main components of silymarin are silybin, isosilybin, dehydrosilybin, silymarin, silymarin, silybin polymer and other flavonoids.  

What is milk thistle used for?

People use milk thistle as a complementary treatment for liver problems, particularly hepatitis and cirrhosis and inflammation of the bile ducts (cholangitis).

Research on silymarin suggests that it may protect the liver from inflammation. Preliminary research suggests that silymarin is an antioxidant, which helps protect the body from cell-destroying substances called free radicals.

Silymarin also may reduce inflammation and block the effects of toxins that harm the liver.
