Think of Calcium Gluconate Anhydrous as the intravenous and oral calcium of choice - a gentle, soluble, and well-tolerated calcium salt widely used in both clinical and nutritional settings. It provides calcium in a form that is easy on the stomach and suitable for patients of all ages.
We produce Calcium Gluconate Anhydrous through the controlled reaction of high-purity gluconic acid with a calcium source, followed by crystallization and drying to remove water of hydration. The result is a fine, white crystalline powder with excellent solubility and consistent quality. Designed for dietary supplements, functional foods, and medical nutrition, our Calcium Gluconate Anhydrous bulk powder delivers a reliable source of calcium without the chalky texture or digestive issues associated with other forms.
