Can insoluble fiber supplements help control blood sugar?

    Last Updated:

    The most commonly used insoluble fiber supplement is wheat fiber. However, it hasn’t been studied enough under well-controlled conditions for researchers to have a full understanding of its effects, and the existing body of research does not clearly support its use for blood sugar management.[1][2][3] The same goes for studies on isolated arabinoxylan, the dominant form of fiber in wheat.[4][5]
