WHAT IS D-ASCORBIC ACID USED FOR?
Dietary supplement
D-Ascorbic Acid is a water-soluble vitamin.
Unlike most mammals and other animals, humans do not have the ability to synthesize D-Ascorbic Acid and must obtain it from the diet.

D-Ascorbic Acid is an essential cofactor in numerous enzymatic reactions, e.g., in the biosynthesis of collagen, carnitine, and neuropeptides, and in the regulation of gene expression.
D-Ascorbic Acid is also a potent antioxidant.

Prospective cohort studies indicate that higher D-Ascorbic Acid status, assessed by measuring circulating D-Ascorbic Acid, is associated with lower risks of hypertension, coronary heart disease, and stroke.
Some studies suggest that D-Ascorbic Acid may be a useful adjunct therapy to mitigate myocardial injury and arrhythmias following cardiac procedures in patients with cardiovascular disease.

There are insufficient data to suggest a link between D-Ascorbic Acid status and the risk of developing a given type of cancer.
Most observational studies examining D-Ascorbic Acid intake in relation to cancer incidence have either found no association or a modest, protective association.
Randomized controlled trials have reported no effect of D-Ascorbic Acid supplementation on cancer risk.
Current evidence on the efficacy of intravenous D-Ascorbic Acid in cancer patients is mainly limited to observational studies, uncontrolled interventions, and case reports.

There is a need for large, longer-duration phase II clinical trials that test the efficacy of intravenous D-Ascorbic Acid in cancer progression and overall survival, especially following the recent report of a significant benefit in pancreatic cancer.
Overall, regular use of D-Ascorbic Acid supplements does not decrease the risk of coming down with the common cold but does decrease symptom severity and shorten the duration of the illness.

Taking supplements once cold symptoms have already begun has limited benefits.
D-Ascorbic Acid supplements are available in many forms.
Several small studies indicate that liposomal-encapsulated D-Ascorbic Acid might have superior plasma bioavailability compared to other formulations.

There is no scientific evidence that large amounts of D-Ascorbic Acid (up to 10 grams [g]/day in adults) exert any adverse or toxic effects.
An upper intake level of 2 g/day was set to avoid diarrhea and gastrointestinal disturbances with high supplemental intakes.
Supplemental D-Ascorbic Acid increases urinary oxalate concentrations, but whether an increase in urinary oxalate elevates the risk for kidney stones is not yet known.
Those predisposed to kidney stone formation may consider avoiding high-dose (≥1 g/day) D-Ascorbic Acid supplementation.
