Foods that cause bloating/Protein powder

Food + bloating

Does protein powder cause bloating?

Short answer

The ingredient list matters more than the protein countProtein powders often combine whey concentrate, inulin and sugar alcohols. Any one of those can upset a sensitive gut.
FODMAP readVaries

The FODMAP load depends on the protein source, sweetener and fiber blend.

01

Two ways it can happen

  1. 01

    Whey concentrate can retain lactose, while plant blends may use whole legumes or large amounts of gums.

  2. 02

    Inulin and polyol sweeteners add fermentable carbohydrate to a drink people consume fast.

02

Portion changes the test

A double scoop with milk and fruit tests four ingredients at once.

03

Run a clean meal test

Mix one scoop with water and keep the rest of breakfast unchanged. If symptoms settle, add the usual ingredients back one at a time.
