Kieselsäure (Silicic Acid)

Kieselsäure, or silicic acid, is a form of silicon oxide commonly used as an anti-caking agent in food products and dietary supplements. It is generally recognized as safe (GRAS) by FDA for use as a food additive. Silicic acid is also naturally present in various plant foods and contributes to dietary silicon intake, which may support bone and connective tissue health. In non-food contexts, it is used in industrial and cosmetic applications.
