Combining Bismuth granule with probiotics for improved digestion

Bismuth granule (Bi) is a rare metal material that combines low toxicity, stability, and special physical properties. The surface of the product is smooth and clean after processing, with a crystal structure of trigonal crystal system. The texture is brittle but not hard, easy to process and cut, and has stable chemical properties at room temperature. It is not easily oxidized in air and is only soluble in strong oxidizing acids such as nitric acid and concentrated sulfuric acid. It is insoluble in water and dilute hydrochloric acid, and has good thermal and electrical conductivity.
