It’s one of zinc salts. 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.
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.
