Yes, xanthan gum is low-FODMAP in normal amounts
Low-FODMAP in the small amounts used in recipes.
The full answer
Xanthan gum is a fiber made by bacteria. Monash University, which created the FODMAP diet, lists it as low-FODMAP in the small amounts used in food.
A typical gluten-free loaf uses about a teaspoon of xanthan gum for the whole recipe, so each slice contains only a fraction of a gram.
In very large doses (over 15 g a day), xanthan gum acts as a laxative and can cause gas. That's far more than anyone eats in normal food.
If you're in the elimination phase and very sensitive, guar gum and psyllium are also generally well tolerated.
