Liver PF combines herbs and other nutrients known to support the liver’s detoxification functions. It is especially directed toward the Phase 2 enzymes, which remove toxins in the liver. Artichoke and milk thistle extracts have been shown to protect liver glutathione levels and to enhance the synthesis and release of bile, an action important for the elimination of toxins from the body. PicroMax™ contains the compound kutkin that, like silymarin flavonoids in milk thistle, supports the liver’s natural regenerative ability, most likely through a stimulation of protein and nucleic acid synthesis. Pantethine activates alcohol metabolizing enzymes and is a co-factor in carbohydrate and lipid metabolism. Alpha lipoic acid is an important antioxidant in its own right that also helps the liver regenerate glutathione. N-acetyl-L-cysteine (NAC) serves as a precursor to glutathione. Uridine is important in the biosynthesis of DNA and in the preservation and transfer of genetic information.
