What it is

Sodium benzoate is the sodium salt of benzoic acid. It is a white, crystalline powder that is soluble in water. It can be produced synthetically or found naturally in small amounts in fruits like cranberries and plums.

Health notes

In the US, sodium benzoate is generally recognized as safe (GRAS) by the FDA when used according to good manufacturing practices. It has been evaluated by international bodies like JECFA and EFSA. Some studies have explored its potential effects on hyperactivity in children, with mixed results and ongoing scientific discussion.
