The liver is one of the body's most important organs. The liver is the body's filter, and keeping that filter clean is the key to helping it operate with optimal efficiency. Whether it is prescription drugs, alcohol, or exposure to any other toxins, Liver Armor keeps the liver clean. Rather than using one or two ingredients, Liver Armor combines optimal doses of the several proven effective ingredients. Alpha Lipoic Acid, Silymarin and N-Acetyl Cysteine (NAC) are potent anti-oxidants that support healthy liver function. NAC is a precursor to glutathione, one of the liver's primary free-radical scavengers. Silymarin, the active bioflavonoid complex of the herb milk thistle, has been shown in vitro to inhibit lipid peroxidation of cell membranes. Taken properly, Liver Armor is an effective way to keep your liver clean.
