D-Glyceric Acid Calcium Salt Dihydrate is utilized in the food and beverage industry as an additive to regulate pH and ensure product stability, while preventing oxidation in chemically sensitive foods such as concentrated juices or instant drink powders. It acts as a highly bioavailable calcium source in dietary supplements, supporting bone and dental health, particularly for the elderly and children. In skincare and cosmetic formulations, it provides moisturizing and humectant properties by drawing water to the skin's outer layer, enhancing hydration, improving texture, and alleviating dryness. It also serves as a mild chelating agent, binding metal ions to prevent oxidation and boost product stability. Its biocompatibility makes it ideal for sensitive skin products, and it may aid skin renewal processes due to its connection to natural metabolic intermediates.
