With diverticulosis there is a risk of toxic build up and it is very important to have a constant intake of beneficial microbes. It is much more difficult to effect the microbes in the large intestine than in the small intestine and larger quantities are required so I would double your dosage. Most important with diverticulitis is diet and exercise. If you are a meat eater there could be a build up of residue which would be good to detox. A gentle gut cleanse would be advisable, and then a focus on supporting the gut lining. A very plant rich varied diet is advisable but needs to be personally tailored.
