MTCC 5856 was tested at 2 billion spores daily for four weeks. This describes the trial, not a personal dose recommendation. 1

The studies used named strains in different conditions; they do not establish interchangeability. 1 2

Does fewer bowel movements mean all IBS symptoms improve?

No. The pilot could not usefully assess severity or quality of life because baseline scores varied greatly. 2

Is a probiotic supplement suitable during a stomach bug?
