Milk Thistle Time-Release [Immune] provides a consistent supply of silymarin (a constituent of Milk thistle) to the liver, giving it nourishment and protection against ingested toxins. The liver performs 500-plus functions, including filtering and destroying toxins in the body. Providing it with proper nutrients allows this essential organ to function at top capacity.Silymarin has shown remarkable ability to help liver cells regenerate and stabilize liver cell membranes. Research shows that it actually changes the structure of the outer liver cell membrane, preventing toxins and poisons from entering the interior of the cell. It also stimulates protein synthesis in liver cells, which generates DNA and RNA. This helps regenerate damaged liver cells. Silymarin does not stimulate growth of malignant liver tissue. As an antioxidant, silymarin is at least 10 times more powerful than vitamin E.One tablet of NSP Time-Release Milk Thistle contains 350 mg milk thistle herb extract, providing 80 percent (280 mg) silymarin.
