Zinc Citrate
Zinc Citrate is a nutritional supplement containing the zinc salt form of citric acid for the purpose of providing zinc. As an essential trace element, zinc is of key importance in many biological processes, acts as an antioxidant and strengthens the immune system.
Overview
Zinc citrate is available as dihydrate and trihydrate and is produced by complete neutralisation of citric acid with a high purity zinc source, subsequent precipitation and dehydration. Zinc citrate is mainly used in dental care products such as toothpastes, mouthwashes and chewing gums due to its antimicrobial and anti-inflammatory effects and its ability to reduce or inhibit the formation of dental plaque and tartar.
In pharmaceuticals, zinc citrate fights common colds. Zinc is increasingly used in food supplements, functional foods and beverages. As an organic mineral source it is preferred in many applications over inorganic sources because of its superior bioavailability, physiological compatibility and nearly neutral taste compared to other zinc salts. Among the organic zinc salts zinc citrate has one of the highest zinc content (31%).
Zinc citrate is supplied as a white to almost white powder. It is practically odourless, slightly soluble in water, soluble in diluted acid and practically insoluble in ethanol (96%). Zinc citrate has an inverse solubility.
