I got SIBO from me not able to digest dairy foods. With the enzymes the smell went away. I am not ever going to eat w/o my diary enzymes again. I am going to do a lot of research on enzymes and lactose intolerance because like u said, enzymes are very important to our digestive systems. I had lots of gas to from SIBO and even though I tried to hold it in at work, it smelt like a was farting.
