Provitalize is a supplement that contains a unique blend of probiotics and natural herbs. Probiotics are live bacteria that are similar to the good bacteria that naturally live in your gut. Some people with IBS have found that taking probiotics may help to improve their symptoms. However, there is no scientific evidence to support the claim that Provitalize specifically helps with IBS. If you are considering taking Provitalize for IBS, it is important to talk to your doctor first.
