Sodium ascorbate

Sodium ascorbate is a form of vitamin C that has been bound to the mineral salt sodium. It is a white or slightly yellow crystalline powder with a slight acidic taste. Sodium ascorbate is more bioavailable than the pure vitamin C, ascorbic acid, and is therefore often preferred in dietary supplements.

Chemical properties

Sodium ascorbate is a reducing agent and can therefore donate electrons to other molecules. This property is utilized in its role as an antioxidant, where it can neutralize harmful free radicals in the body. Sodium ascorbate is also a buffering agent, which means it can help maintain a stable pH in a solution.

Health benefits

Sodium ascorbate has all the health benefits of vitamin C, but is better absorbed by the body and less likely to cause digestive problems. It can support immune system function, aid in the production of collagen, and help the body absorb iron. It is also used in the treatment of scurvy, a disease caused by vitamin C deficiency.

Safety and side effects

While generally safe, high doses of sodium ascorbate can cause diarrhea, nausea, and stomach cramps. People with kidney disease or high blood pressure should be cautious with sodium ascorbate, as it contains sodium.

Production

Sodium ascorbate is produced by dissolving ascorbic acid in water and adding an equivalent amount of sodium bicarbonate. The mixture is then evaporated to yield the sodium ascorbate crystals.
