I just found out that people who has an intolerance to lactose can take lactase pills if they want to consume dairy. I was wondering if there is anything like this for gluten? Or onions and garlic? The fodmap diet has worked for me and I believe onion, garlic and wheat/gluten are the main culprits so a pill like this would make eating out so much easier as nearly all foods contain one of the above.
Also, is it possible to not be lactose intolerant (blood test was fine) but still be affected by it?
