I was having problems with lots of foods. Even theoretically low FODMAP foods like oranges were turning my stomach. Then I came across this meta-analysis which shows that supplementation with Lactobacillus (e.g. Lactobacillus Casei, i.e. Yakult) improves symptoms for people better than a FODMAP reducing diet. The bacteria gets in there and has a go at the indigestible carbs before your body freaks out.
Since having some each day I've gone from feeling uncomfortable every day (despite a restrictive diet) to feeling pretty good (but still cutting out a lot of things).
Remember if you are going to supplement with other non-supplement-style yogurts that you need to ensure it is live culture, otherwise you aren't doing anything for your gut microbiome.
Have you tried it? Did it work or not?
