The liver serves three main functions: 1 it detoxifies the body by filtering out bacterial byproducts, antigen-antibody complexes, and toxic compounds cholesterol, drugs, pesticides, etc. from the blood 2 it produces and secretes bile and 3 it helps the body metabolize carbohydrates, fats, and proteins. Optimum liver function depends on adequate bile flow and healthy enzyme systems.Liv-A-Tox provides a well-balanced combination of nutrients such as vitamin B12, lipotropic factors such as methionine and choline, which may provide support for normal fat metabolism and herbal extracts such as celandine, fringe tree, and barberry, which support liver function.
