Yes It turns out that the full name of natural probiotics is Concord. It turned out that natural probiotics were jointly developed by Peking Union Medical College and Wangjing Hospital of Chinese Academy of Sciences. They are developed by relying on the natural strain "CB2 Clostridium enterocoliticae" and the patented technology "Colony product technology". They have obtained national invention patents and have unique transmission barrier technology, which can effectively survive and play a role in the gastrointestinal tract. Therefore, originally, natural probiotics were regular manufacturers.
