Ascorbic Acid One Gram, provides 1 g of pure, crystalline vitamin C in each vegetarian capsule.
High amounts of vitamin C – several grams daily – have been advocated for optimizing both immune function and antioxidant support. Evidence for the efficacy of consuming high amounts of ascorbic acid is due in large part to the groundbreaking research conducted in the 1970s and 1980s by two-time Nobel Prize winner, Linus Pauling, PhD.
Ascorbic acid (vitamin C) has several mechanisms of action that give it wide-ranging value to body structures and functions. It is a potent water-soluble antioxidant; it enhances the immune system; and it supports connective tissue formation.
Vitamin C is essential for the support of wound healing because it is a cofactor for the synthesis of collagen and other connective tissue components. The combined effects of vitamin C on collagen synthesis, antioxidant status, and immune function make it an important nutrient for surgery patients and wound healing.
Vitamin C is necessary for the action of the enzymes involved in phase I liver detoxification. In addition, as an antioxidant it helps quench the free-radical intermediates created during this first phase of detoxifying substances in the liver. Furthermore, vitamin C raises levels of the important antioxidant glutathione by increasing its rate of synthesis, thus enhancing the liver's phase II detoxification as well. Vitamin C can also protect against the toxic effects of heavy metals such as lead, aluminum, and cadmium.
The ascorbic acid products manufactured by Thorne contain only pure, crystalline vitamin C – without added corn starch, magnesium stearate, or other lubricants and diluents to ensure greater bioavailability and efficacy.
