Zinc lactate is the zinc salt of lactic acid, an organic compound that combines one zinc ion with two lactate molecules. It appears as a white to off-white crystalline powder that dissolves readily in water, offering a highly bioavailable source of zinc for pharmaceutical and nutritional applications. The compound is typically produced by reacting lactic acid with a zinc source such as zinc oxide or zinc carbonate, followed by purification and crystallization.
As a zinc supplement, zinc lactate is valued for its superior absorption compared to inorganic zinc salts like zinc oxide or zinc sulfate. It is widely used in oral rehydration solutions, dietary supplements, and functional foods, where its mild taste and high solubility enhance patient compliance. The ingredient also finds use in personal care formulations and as a catalyst in chemical synthesis.
