What researchers measure

Primary outcomes

  1. daily gastrointestinal symptoms

    The following gastrointestinal were rated and reported by the study participants on a daily based. Bloating, rumbling, feeling of fullness, passage of gas, abdominal discomfort (pain and cramps). The rating was done based on a number scale. 0 not at all and 4 extremely.

    Time frame: was assessed daily during 4 week intervention

Secondary outcomes

  1. validated questionnaires

    Three validated questionnaires were used. Two of them were specially designed to evaluate gastrointestinal symptoms and quality of life of people with constipation. The third questionnaire was a validated questionnaire to report stress levels and related changes of stress levels. 1. Patient assessment of constipation symptoms (PAC SYM) 2. Patents assessment of constipation quality of life (PAC QOL) 3. Perceived stress questionnaire (PSQ20)

    Time frame: assessed at visit 1 (before) and at visit 2 (after 4 week intervention)

  2. stool consistency

    The stool consistency was rated referring to the Bristol stool scale. A scale indicated with pictures how the stool consistency can be rated.

    Time frame: reported at days with stool during 4 week intervention

  3. Adverse events

    All adverse events which might be linked to the study product were reported. As the tested study product is a food product being safe for consumption as food no specific parameter to define safety were defined.

    Time frame: assessed at visit 1 (before) and at visit 2 (after 4 week intervention)

  4. Stool frequency

    The stool frequency was reported on each day with bowel movement.

    Time frame: reported at days with stool during 4 week intervention
