LiverCare assists normally functioning liver cells; it has antioxidant properties that support liver cell integrity and is a formula which assists in preserving existing liver strength when dealing with occasional overwhelming challenges. Keep in mind, the liver is the largest internal organ and it is important the liver is functioning on a normal level when performing more then 500 different functions. Silymarin, the active component of Milk Thistle, acts by maintaining healthy liver cell function. LiverCare does the same thing. LiverCare also supports the livers function when challenged by toxins not just in our food, water and air, but also increased consumption of protein and prohormones. A benefit LiverCare has over Milk Thistle is it does not interfere with medication when taken together.
