Think of Calcium Glycerophosphate as a two-in-one mineral donor with a clever twist: it delivers both calcium and phosphorus in a highly absorbable, glycerol-bound form. Your body already knows it well-this compound naturally plays key roles in building bones, supporting cell membranes, and keeping your energy metabolism humming along.
We make it by carefully reacting glycerophosphoric acid with a high-purity calcium source, then crystallizing and drying the result. The final product? A fine white powder that dissolves nicely and maintains consistent quality. Whether you're formulating dietary supplements, oral care products, functional foods, or clinical nutrition, our bulk Calcium Glycerophosphate powder offers a balanced, convenient source of two essential minerals in one ingredient.
Calcium Glycerophosphate: A Dual Mineral Source for Bone Health
One of the first questions buyers ask is simple: what is calcium glycerophosphate? It is a calcium and phosphorus source used across supplements, food and oral care products. Chemically, it is the calcium salt of glycerophosphoric acid - a white, odorless crystalline powder with the CAS number 27214-00-2 and the food additive designation E383. What makes it useful in formulations is that it supplies both calcium and phosphorus in a single, well-tolerated compound, with solubility in water that suits liquid and semi-solid systems. That dual mineral profile also explains why it is so often discussed in the context of bone health - and the question "is calcium glycerophosphate good for bones" deserves a measured answer: calcium contributes to the maintenance of normal bones as part of an adequate diet, and a balanced calcium-to-phosphorus intake is part of healthy mineral nutrition. Products using this ingredient typically position it in bone-support or general mineral supplement lines rather than making outcome-specific promises. For formulators, the practical starting point is grade selection - food grade, pharmaceutical grade or FCC grade, each with a different regulatory path - followed by confirming elemental calcium content per serving and how the ingredient behaves alongside other minerals in a multi-mineral formula. Measured, nutrition-fact-based claims keep the product credible and regulatory-safe.
