Milk Thistle-

Numerous scientific studies have explored Milk Thistle and a group of its constituents called silymarins. Many of these clinical studies have demonstrated that this herb supports healthy liver function and provides powerful antioxidant protection.*

Alpha Lipoic Acid-
Alpha-lipoic acid is an antioxidant made by the body. It is found in every cell, where it helps turn glucose into energy. Antioxidants attack "free radicals," waste products created when the body turns food into energy.
Other antioxidants work only in water (such as vitamin C) or fatty tissues (such as vitamin E). But alpha-lipoic acid is both fat and water soluble. That means it can work throughout the body. Antioxidants in the body are used up as they attack free radicals, but evidence suggests alpha-lipoic acid may help regenerate these other antioxidants and make them active again.*

Artichoke extract-
Ongoing research seems to indicate that artichoke indeed have medicinal qualities. Most significant appears to be its beneficial effect on the liver. In animal studies, liquid extracts of the roots and leaves of artichoke have demonstrated an ability to protect the liver, with possibly even to help liver cells regenerate. Although research is not yet conclusive, scientists were optimistic that its long-standing use in humans for digestive and bowel problems was indeed justified.*
