Liver Optimizer combines herbs and other nutrients known to impact detoxification and overall liver function. It is especially directed toward Phase  2 enzymes, which assist in the processing and removal of toxic metabolites from the body. Milk thistle extract has been shown to affect glutathione levels and aid in the regeneration of liver cells. R-alpha lipoic acid (the bioactive form) and N-acetyl-L-cysteine (NAC) are also involved in the regulation of glutathione. Sulforaphane GlucoSinolate, from broccoli, is a precursor to sulforaphane, an inducer of Phase 2 detoxifying enzymes. Artichoke Extract supports glutathione levels and promotes bile production. B complex vitamins support liver enzymes and promote liver regeneration. Additionally, the nucleoside uridine supports liver detoxification, as does NAC. Suitable for vegetarians. It is recommended to take 3 tablets per day, preferably 1 with each meal or as directed by your qualified healthcare professional. If you have a medical condition (especially diabetes or being treated for glucose control), are pregnant, lactating, trying to conceive, under the age of 18, or taking medications (especially for glucose control), consult your healthcare professional before using this product. Keep out of reach of children. Store in a cool, dry place.
