What is Calcium Gluconate?
Calcium Gluconate is the calcium salt of gluconic acid, widely valued as a source of supplemental calcium due to its gentle action on the digestive system and good bioavailability compared to some other calcium salts. It is a white, odourless crystalline powder or granular material that is moderately soluble in water, making it suitable for both oral supplement formulations and, in pharmaceutical grade, for intravenous calcium replacement therapy.
Polychem Industries supplies Calcium Gluconate in food grade and pharmaceutical grade to nutritional supplement manufacturers, pharmaceutical companies, and food fortification companies across India and internationally. Its excellent tolerability, established safety profile, and effectiveness as a calcium source make it one of the most widely used calcium compounds in both food and medical applications.
