Description

Zinc Lactate Trihydrate is a high-purity, bioavailable zinc salt of lactic acid, widely recognized for its superior stability and solubility profile. This compound serves as a critical source of essential zinc in applications where bioavailability, neutral taste, and compatibility are paramount. It is a key ingredient for manufacturers in the nutraceutical, food fortification, and personal care industries seeking a reliable and effective zinc supplement.

Application

• Dietary Supplements & Nutraceuticals: Used as a bioavailable zinc source in capsules, tablets, and liquid formulations to support immune function, metabolism, and overall wellness.
• Food & Beverage Fortification: An ideal fortificant for cereals, nutritional bars, dairy products, and beverages due to its good solubility and minimal impact on flavor and color.
• Pharmaceutical Preparations: Employed in lozenges, syrups, and other medicinal products as a therapeutic agent for zinc deficiency.
• Personal Care & Cosmetics: Incorporated into toothpaste, mouthwash, and skincare products for its astringent, anti-odor, and skin-conditioning properties.
• Animal Nutrition (Feed Premixes): Serves as a nutritional zinc supplement in feed for livestock, poultry, and aquaculture to promote growth and health.
