Consumer Advice ​

Sodium ascorbate is the sodium salt of vitamin C. It is more water-soluble and less acidic than ascorbic acid, and is used as an antioxidant in drinks, meat products and fruit products to prevent oxidation and preserve colour. It provides vitamin C in the body, has a high safety margin, and poses no health risk at authorised levels. People on low-sodium diets should simply count its sodium content toward their daily intake.
