What is Lactobacillus casei?
Probiotics such as Lactobacillus casei (L. casei) are generally considered safe and helpful in regulating the digestive system. There have been many promising studies involving L. casei.
Researchers in a 2007 trial studied a probiotic drink containing L. casei, L. bulgaricus, and S. thermophiles. They concluded that it may reduce the incidence of antibiotic-associated diarrhea and C. difficile-associated diarrhea. No adverse events were reported.
A 2003 study showed that a probiotic drink containing Lactobacillus casei Shirota was a beneficial adjunctive therapy for people with chronic constipation. A later study looked at people with Parkinson’s disease. That one revealed that regular intake of milk fermented with Lactobacillus casei Shirota can improve bowel habits of people with the disease.
Researchers for a 2014 clinical trial found that L. casei supplements can help alleviate symptoms and improve inflammatory cytokines in women with RA.
There is a growing body of research into L. casei and other probiotics. But to date, the U.S. Food and Drug Administration (FDA) hasn’t approved L. casei or any other probiotic for the treatment of a specific health problem.
When you don’t have enough of the good bacteria, adding more L. Casei to your diet can help regulate your digestive system.
Probiotic supplements containing L. Casei are used to prevent or treat diarrhea. This includes infectious diarrhea, traveler’s diarrhea, and antibiotic-associated diarrhea.
It may also have some effect on other digestive problems, including:
✓ Crohn’s disease
✓ inflammatory bowel disease (IBD)
✓ irritable bowel syndrome (IBS)
✓ lactose intolerance
✓ ulcerative colitis
L. casei may also be useful for:
✓ acne, hives, and fever blisters
✓ allergies, eczema, and dermatitis
✓ cold, flu, and respiratory infection
✓ ear infection (otitis media)
✓ oral health problems, such as plaque, gingivitis, and canker sores
✓ Helicobacter pylori infection, which causes stomach ulcers
✓ Lyme disease
✓ necrotizing enterocolitis (NEC), a serious intestinal disease common in premature infants
✓ rheumatoid arthritis (RA)
✓ urinary tract and vaginal infections
