Zinc lactate

Zinc lactate is an organic compound formed from the reaction of lactic acid and a high-purity zinc source, resulting in a white to almost white fine powder that is nearly odourless and highly soluble in water[2][8]. It serves as a highly bioavailable source of dietary zinc and is used primarily as a nutrient supplement, food fortifier (notably in infant formula), and as an ingredient in oral care products such as toothpaste and mouthwash due to its antimicrobial properties[1][2][3][5]. Zinc lactate inhibits the formation of dental plaque and tartar by neutralizing volatile sulfur compounds produced by oral bacteria, making it effective for managing halitosis (bad breath)[3]. As an essential trace element, it supports protein synthesis, wound healing, immune function, antioxidant defense mechanisms (e.g., upregulating antioxidant enzymes), muscle contractility regulation, blood stability, normal tissue function maintenance, digestion/metabolism of phosphorus[1][4][5][6]. Zinc lactate is preferred over inorganic salts for supplementation because of its superior physiological compatibility and taste profile[2].
