Description

Calcium Citrate is a highly bioavailable, water-soluble calcium salt of citric acid, widely recognized for its superior absorption and neutral taste. This compound is essential for providing a concentrated and easily assimilated source of calcium, a critical mineral for structural integrity and metabolic function. It serves as a vital ingredient for manufacturers in the nutraceutical, food & beverage, and pharmaceutical industries, where consistent quality and regulatory compliance are paramount.

Application

• Dietary Supplements & Fortified Foods: As a primary calcium source in tablets, capsules, powders, and beverages like juices and plant-based milks.
• Pharmaceutical Preparations: Used in antacid formulations and as a calcium supplement in OTC and prescription medications.
• Food Additive (E333): Functions as a firming agent, buffer, and preservative in various processed foods, including dairy products, canned vegetables, and baked goods.
• Animal Nutrition: Incorporated into feed premixes for livestock, poultry, and pets to support bone health and eggshell quality.
• Technical & Industrial Uses: Acts as a sequestrant in water treatment and as a component in some ceramic and cement formulations.

Quality Control

We supply Calcium Citrate that meets stringent quality standards, including FCC (Food Chemicals Codex) and USP (United States Pharmacopeia) grades, ensuring suitability for food, nutraceutical, and pharmaceutical applications. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent caking and degradation.
