Clostridium butyricum is the best bacterium to the intestinal tract, butyric acid is the best acid to the intestinal tract.

Butyric acid is the most important substance for colon’s energy metabolism, reparation and balance immunologic. When the Clostridium butyricum was lacked, the butyric acid will excrete insufficiently, on one hand, it will block the colon’s energy metabolism and reparation; on the other hand, it will lead the colon’s balance immunologic disorderedand the abnormal expressing of TNF-α、IL-1 and IL-8, all of this will cause inflammation and ulcer of intestinal mucosa，and then people will contract colonitis, IBS or chronic diarrhea.

The oral clostridium butyricum praeparatum, Live (Clostridium butyricum CGMCC0313-1) can satisfy the butyric acid request of the colon.However, Bacillus bifidus and Bacillus acidi lactici could not excrete butyric acid, the excreta of them is short-chain fatty acid that can only used when they have been converted into butyric acid. Therefore, Clostridium butyricum is the best bacterium to the intestinal, butyric acid is the best acid to the intestinal tract .
