What is lactobacillus, and what is it used for?
Lactobacillus refers to some of the species of bacteria that live within human digestive and genitourinary tracts and are essential for maintaining good health of these systems. The “good” bacteria including Lactobacillus species help the digestive system break down food and absorb nutrients and prevent the proliferation of infection-causing organisms in the digestive and genitourinary tracts.
Lactobacillus acidophilus is one of the most common species of bacteria used as a probiotic supplement. Lactobacillus supplements help restore normal bowel flora, inhibit the growth of disease-causing pathogens and improve local immunity. Lactobacillus controls diarrhea and facilitates proper stool formation by promoting water reabsorption in the colon.
Different formulations of lactobacillus supplements are available over the counter (OTC) and are taken orally to improve gut health, particularly after antibiotic use for infections. Antibiotics destroy the good bacteria along with the disease causing pathogens and the loss of gut flora can lead to impaired digestion and diarrhea. Lactobacillus suppositories and vaginal tablets are used to reduce bacterial overgrowth in the vagina. Yogurt is a natural source of lactobacillus.
The suggested uses of lactobacillus include:
- Do not use lactobacillus in immunocompromised patients. Supplements with live bacteria may be associated with invasive fungal infection.
- Do not use lactobacillus in patients with gastrointestinal perforation, the bacteria can get out of the bowel and may cause systemic infection.
- Do not use lactobacillus if you are sensitive to soy or milk protein.
- Use lactobacillus with caution if you are lactose intolerant.
- Lactobacillus formulations differ in composition and biologic activity. Do not use different products interchangeably.
