Theramedix CDX does not contain chitinase. They are using cellulase. Is there any evidence cellulase breaks down chitin? IMO this is wishful thinking.
"The cell contains some fungal cellulose or a compound called chitin. Chitin is a polysaccharide, or carbohydrate, which is structurally very similar to cellulose. For the same reasons cellulase may help remove undigested fiber in the colon, it has been used in breaking down this "cellulose-like" chitin.*"
