What is Florastor Kids?

Florastor Kids is a special type of yeast that is also known as Brewer's Yeast, Hansen CBS 5926, Levure de Boulangerie, and Probiotic.

Florastor Kids has been used as a probiotic, or "friendly bacteria," to help stop harmful bacteria from growing in the stomach and intestines.

Florastor Kids is likely effective in alternative medicine as a way to help prevent diarrhea caused by taking antibiotics or using a feeding tube. This medicine is also likely effective in treating diarrhea in babies and children.

Florastor Kids has been used as a possibly effective aid in preventing the return of diarrhea caused by Clostridium difficile (C. difficile). However, this product may not be effective in treating the first episodes of this type of diarrhea. This medicine is also possibly effective in treating "traveler's diarrhea," diarrhea in people with HIV, and stomach ulcers caused by Helicobacter pylori.

Other uses that have not been proven with research include irritable bowel disease, Crohn's disease, ulcerative colitis, cystic fibrosis, urinary tract infections, yeast infections, lactose intolerance, and other conditions.
