Thorne's ascorbic acid (Vitamin C) is NSF Certified for Sport®. Most people are aware that vitamin C promotes healthy immune function.* But vitamin C also has several additional mechanisms of action. For example, it's an essential nutrient for promoting wound healing and supporting injury repair.* Vitamin C also plays a role in liver detoxification and helps protect against the toxic effects of heavy metals such as lead, aluminum, and cadmium.* Thorne's Ascorbic Acid contains only crystalline vitamin C – with no added corn starch, magnesium stearate, or other lubricants and diluents – to ensure optimal absorption and efficacy.* The combined positive effects of vitamin C on collagen synthesis, antioxidant status, and immune function make it an important nutrient for surgery patients and for supporting wound healing.* Vitamin C is necessary for the proper action of those enzymes involved in phase I liver detoxification.* In addition, as an antioxidant, vitamin C helps quench the free-radical intermediates that are created during this first phase of the detoxification of harmful substances in the liver.* Furthermore, vitamin C helps increase the level of the important antioxidant glutathione by increasing glutathione's rate of synthesis, which enhances the liver's phase II detoxification.*
