Vitamin C is a popular vitamin and antioxidant. The body cannot make its own, so getting enough vitamin C from the diet is essential. Vitamin C is sometimes considered the “go-to” supplement as it has a wide range of benefits in the body. It is most commonly used to strengthen immunity and prevent the cold and flu, but it also improves wound healing time, boosts immunity, and promotes healthy, youthful skin, strong bones and clear blood vessels. Interestingly, the only species that cannot produce their own vitamin C are also the only species who develop atherosclerosis, ie. hardening of the arteries. This suggests a clear role for vitamin C in cardiovascular health.

Vitamin C is a potent antioxidant, protecting the body from disease and aging and even helping recycle other antioxidants such as vitamins A and E, glutathione and lipoic acid, making them more effective. Due to its anti-inflammatory and anti-histamine effects, vitamin C is also effective for allergy relief, and at high doses it can act as a gentle laxative for occasional constipation. Vitamin C is needed for the synthesis of adrenal hormones, making it an important nutrient for combating the negative effects of stress.

AOR’s Vitamin C formula is a high dose, pure ascorbic acid and can benefit everyone, especially those who have a family history of cardiovascular disease, seasonal allergies, weak immune system or people who do not regularly consume citrus fruits or other foods rich in vitamin C.

There is a fair amount of depth to the ascorbic acid research pertaining to cancer, most of it on the preventative aspect. Such preventative effects may be accounted for, in part, by ascorbic acid’s ability to detoxify carcinogens directly, as well as blocking carcinogenic processes via its antioxidant activity. Vitamin C can prevent the formation of such carcinogens as nitrosamines in foods and in the gastrointestinal tract. It can also detoxify such chemical mutagens and carcinogens as anthracene, benzo[a]pyrene, organochlorine pesticides and heavy metals. High concentrations of ascorbic acid in gastric juice may reduce the risk of gastric cancer by inhibiting the formation of carcinogenic N-nitroso compounds. Additionally, increased oxidative stress to the gastric mucosa has been reported in H. pylori-associated gastritis, a condition that predisposes to gastric cancer. There is preliminary evidence suggesting that vitamin C can inhibit the growth of Helicobacter pylori.


For those suffering from hypertension, there is an indication that ascorbic acid may improve endothelial-dependent vasodilation. That indication is likewise evident in those with hypercholesterolemia as well, and ascorbic acid may also help restore nitric oxide-mediated flow-dependent vasodilation in those with congestive heart failure.


The well-worn association between vitamin C and the common cold may be explained by the anti-histamine effects of the vitamin. These same effects also reduce the immunosuppressive activity of histamine, thus enhancing neutrophilic chemotaxis, giving ascorbic acid an overall immunomodulatory role as well.

Respiratory Conditions

Clinical studies have demonstrated that ascorbic acid may protect against asthma and other obstructive pulmonary diseases, as well as protect the airways against the effects of allergens, viral infections and irritants in some. In one study, a dosage of 1500 mg of vitamin c per day was given for two weeks; it was found that the ascorbic acid supplementation provided a protective effect against exercise-induced airway narrowing in asthmatic subjects. Allergens, viruses and irritants, including ozone, nitrogen oxides and sulfur oxides, subject the airways to increased oxidative stress and inflammation which can lead to bronchoconstriction. While the antioxidant properties of ascorbic acid are obviously critical in dealing with such conditions, its newly re-examined anti-inflammatory role can also be accredited.

Lead & Metal Chelation

Ascorbic acid also acts as a cofactor in various biochemical reactions to reduce the transition metals, iron and copper. It also protects against the tissue-damaging effect of some toxic chemicals and heavy metals. High serum levels of ascorbic acid have been reported to co-relate with a decreased prevalence of elevated blood lead levels. The mechanism of the possible lead-lowering action of vitamin C is unclear. One study compared ascorbic acid directly to the lead-chelating agent EDTA and found them to have equivalent activity with respect to chelating lead.

Collagen Formation

Beyond its antioxidant role, scientists will more often than not regard ascorbic acid’s primary activity to be the regulation of collagen formation. Collagen is a protein that makes up the connective tissue found in skin, bones, cartilage, teeth, muscles and the walls of blood vessels. It is the most abundant of the fibers contained in connective tissue which gives our body form and supports our organs. Vitamin C’s role in collagen production begins inside the cells, where it hydroxylates (adds hydrogen and oxygen) to two amino acids: proline and lysine. This helps form a precursor molecule called procollagen that is later synthesized and modified into collagen outside the cell membranes. Without vitamin C, collagen formation is disrupted, causing a wide variety of problems throughout the body.

How Much Vitamin C Do We Need?

The officially recommended daily allowance of vitamin C, which stands at 90 milligrams per day, is an artificial figure obtained through a combination of social convention and bureaucratic convenience. Most scientifically determined optimal daily allowances range from 300 milligrams to 1.2 grams each day, with some older anti-cancer clinical trials experimenting with as much as 5 grams! It should be noted, however, that dosages on that end of the scale may be biochemically inefficient as ascorbic acid is a water-soluble compound that is easily absorbed but is not stored in the body – excess amounts are simply excreted.
