Description

L-Threonic Acid Calcium Salt is the calcium salt derivative of L-threonic acid, a sugar acid metabolite of vitamin C. This compound is valued for its role as a bioavailable source of calcium and a potential antioxidant synergist. It is primarily utilized in the pharmaceutical and nutraceutical industries for the formulation of dietary supplements and functional food ingredients.

Application

• Dietary Supplements: As a source of bioavailable calcium in bone health and mineral fortification formulas.
• Nutraceuticals: Incorporated into functional foods and beverages for its potential antioxidant and mineral delivery properties.
• Pharmaceutical Intermediates: Used in the synthesis of more complex pharmaceutical agents or as an active pharmaceutical ingredient (API) in certain preparations.
• Cosmetic Ingredients: Potential application in skincare formulations for its antioxidant and skin-conditioning benefits.
• Animal Nutrition: As a mineral supplement in feed premixes for livestock and poultry.
• Research & Development: Serves as a standard or reagent in biochemical and nutritional studies.
