Zinc Lactate Trihydrate is the zinc salt of lactic acid, crystallized with three molecules of water, combining an essential dietary mineral (zinc) with a naturally occurring, well-tolerated organic acid (lactic acid). This pairing gives the compound notably high bioavailability compared to less soluble inorganic zinc salts, since the lactate counterion helps keep zinc ions in a readily absorbable form in aqueous and biological systems. Supplied by Sarchem Labs as a white-to-off-white crystalline powder, it dissolves readily in water, which makes it straightforward to incorporate into liquid, semi-solid, and solid formulations alike.
Because of its high bioavailability and mild chemistry, Zinc Lactate Trihydrate is widely used as a zinc-fortification ingredient in pharmaceutical and nutraceutical supplements, including tablets and syrups, where efficient zinc absorption matters. It also plays a role in food preservation and as a food-grade additive, in oral care products such as toothpaste and mouthwash (where zinc salts are valued for their effect on oral bacteria and odor), and in cosmetics and personal care formulations. Beyond consumer products, it is also used in general industrial and laboratory applications wherever a soluble, mild zinc source is required.
