Begin with the formula
Ask which fibres are present and in what amounts. Inulin, FOS, PHGG and acacia are distinct materials with different properties. An ingredient list alone does not show that the finished serving matches the conditions used in a study.
Separate texture from digestive tolerance
A powder can mix into a light drink and still cause discomfort for some people. Low viscosity is a texture property, not proof that a blend will be well tolerated. The amount consumed and individual response also matter.
Review the finished product
Check fibre per serving, preparation directions, suitability and the basis for each claim. Follow the directions for a released product rather than using general formulation information as serving advice.
