Zinc citrate  is a chemical compound, inorganic salt of citric acid (α and β-hydroxytricarboxylic acid). 

The industrial production of citric acid takes place by mycological fermentation of raw sugar from Aspergillus niger and subsequent crystallisation with alkaline solutions.

It appears as white powder.

Zinc in the human body constitutes an important immunological barrier and its deficiency can lead to diseases of the skin, bones and sight.
