Description

Calcium Citrate is a highly bioavailable organic calcium salt, essential for numerous industrial and nutritional applications. Its superior solubility profile compared to other calcium sources makes it a critical ingredient for effective fortification and supplementation. This compound is primarily sought by manufacturers in the food & beverage, pharmaceutical, and dietary supplement industries for its role as a calcium fortifier, antacid, and buffering agent.

Application

• Dietary Supplements & Nutraceuticals: A key source of bioavailable calcium in tablets, capsules, and powder formulations to support bone and dental health.
• Food & Beverage Fortification: Used to enrich products like juices, plant-based milk alternatives, cereal, and flour with essential calcium without significantly affecting flavor.
• Pharmaceuticals: Serves as an active ingredient in antacid preparations and as a calcium supplement in various medicinal products.
• Functional Food Additive: Acts as a firming agent, buffer, and sequestrant to improve texture and stability in processed foods.
• Animal Feed & Pet Nutrition: Incorporated into feed premixes to ensure adequate calcium intake for livestock, poultry, and pets.
• Technical & Industrial Uses: Employed in certain chemical synthesis processes and as a starting material for other citrate salts.
