Product Overview


  • One Gram
  • Dietary Supplement
  • Hypoallergenic

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.

Love Thorne but not GMOs

Posted by Jodi-Hummingbird on Sep 22, 2012

Thorne is one of the main go-to brands for supplements without many added nasties. It is disappointing their vitamin C is not GMO free. If this product beocmes GMO free I will start buying it again but for now this one is off my shopping list. The large capsule count on this product is great. Please make a GMO free version Thorne!

Great Vitamin C supplement

Posted by MrJellybean on Jun 27, 2012

Thorne Research is probably my favorite supplement company. Always high quality with no fillers like magnesium stearate. Good sized pill that you can take several times a day if megadosing C.
