Zinc Citrate Dihydrate

Zinc citrate dihydrate is the trizinc salt of citric acid carrying two molecules of water of crystallisation, supplied by Nustras as a fine powder in standard and micronised grades and used as a source of the trace mineral zinc for supplements, fortification and oral-care products. Zinc is an essential trace element and a cofactor for many enzymes.

It is formulated into mineral and multimineral supplements in capsule, tablet, chewable and powder form, into vitamin-mineral premixes, fortified foods and beverages, and into toothpaste and mouthwash formulations.

The material is a fine powder, in standard and micronised grades, with CAS number 5990-32-9, molecular formula C12H14O16Zn3 and a molecular weight of 610.4. Zinc content, loss on drying, particle size and pH are standardised to specification; identity and assay are confirmed by complexometric titration or atomic absorption spectroscopy, and heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies zinc citrate dihydrate in bulk commercial quantities, in sealed packaging, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Zinc (as zinc citrate) is a permitted mineral source in major supplement and food markets; buyers confirm the elemental-zinc contribution and permitted level for their application.
