The Acidophilus and Suprema dopilius are probiotics that aid in establishing a healthy microflora in the gut. Probiotics are very safe and rarely create any unwanted side effects or bad reactions.

Taking both together will ensure that you get plenty of live cultures to support the health of your gastrointestinal system.
