Sodium ascorbate is one of a number of mineral salts of
bioavailable than any other form of vitamin C supplement.[2]
Sodium ascorbate normally provides 131 mg of sodium per 1,000 mg of ascorbic acid (1,000 mg of sodium ascorbate contains 889 mg of ascorbic acid and 111 mg of sodium).
As a food additive, it has the E number E301 and is used as an antioxidant and an acidity regulator. It is approved for use as a food additive in the EU,[3] USA,[4] Australia, and New Zealand.[5]
In
Production
Sodium ascorbate is produced by dissolving
isopropanol
.
