摘要

Sodium L-ascorbate (C6H7NaO6, CAS registry No. 134-03-2, Fig. 1) is one of a number of mineral salts of ascorbic acid (vitamin C). [1] The human body does not produce its own vitamin C; it gets it from food and other sources. Ascorbic acid is highly reactive, and the most powerful and fastest acting form of vitamin C. However, it is too acidic to safely use intravenously. While ascorbic acid is more powerful fighting infections and perhaps even heart disease, some people find as the age that ascorbic acid becomes harder to take by mouth. Cells in the stomach are used to a highly acidic environment, but sometimes lesions form at the bottom of the esophagus, as tissues leading to the stomach are not acid protected. For people who are experiencing discomfort while swallowing, and are not fighting the cold or the flu, sodium ascorbate powder can be an excellent choice. Moreover, the degradation of Ascorbic acid is inevitable. [2-4] As a form of vitamin C, the basic properties and health benefits of sodium ascorbate are virtually identical with ascorbic acid, but the mineral salt buffers, thus lowers the acidity of ascorbic acid. [5] The buffered sodium ascorbate may enter the blood stream more slowly than ascorbic acid when taken orally. Sodium ascorbate is used for intravenous infusions, intramuscular injections, and is used orally to avoid the acidity of ascorbic acid by sensitive persons. Moreover, as a food additive, it has the E number E301 and used as antioxidant and an acidity regulator. It is approved for use as a food additive in the EU, USA, Australia and New Zealand. [6-8]
