They do a decent job. Chitin is what mushrooms produce to make their cell membrane. Helps to protect Candida against the immune system. The protection of Chitin's immune system against Candida is not complete as they would like you to think, but by disrupting Candida's ability to produce chitin, the Candida membrane is deteriorating and it is easier to kill. As with other herbal formulas and medications, the ingredient that disrupts the synthesis of chitin does not reach Candida that lurks outside the circulatory system. And they do not do anything to deal with Candida spores.
