OriginZinc citrate is synthesized from zinc salts and citric acid, both widely available industrial chemicals. The compound is produced through acid-base neutralization, combining zinc oxide or zinc chloride with citric acid in aqueous solution.
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. Although the mechanism of action is not completely known, zinc supplementation may be used to increase immunity against viruses or may interfere with the replication of certain viruses, such as the human papillomavirus (HPV).
