The term "probiotics" refers to dietary supplements or foods that contain beneficial, or "good," bacteria normally found in your body. Although you don't need probiotics to be healthy, these microorganisms may assist with digestion or help protect against some harmful bacteria.
There is growing public and scientific interest in probiotics. Researchers are studying whether probiotics taken as foods or supplements can help treat or prevent illness, such as:
Vaginal yeast infections
Diarrhea following treatment with certain antibiotics
In addition, recent research suggests a number of new potential uses for probiotics. One study in Sweden found that a group of employees who were given probiotics missed less work due to illness than did employees who were not given probiotics. Other studies have found probiotics to be helpful in managing the signs and symptoms of irritable bowel syndrome (IBS)...as well as IBD.
Listen to your doc, take a good quality one, one that doesn't contain a bunch of un-necessary stuff like aspertame, sugar, additives, food coloring, ect. Primadophilus Reuteri made by natures way is an excellent one that I use and highly recommend.
My bum is broken....there's a big crack down the middle of it! LOL :)
