What is BD Lactinex?

Lactobacillus is a bacteria that exists naturally in the body, primarily in the intestines and the vagina. Lactobacillus helps maintain an acidic environment in the body, which can prevent the growth of harmful bacteria. Lactobacillus has been used as a probiotic, or "friendly bacteria."

Acidophilus and bulgaricus (helveticus) are two different types of lactobacillus that are combined in this product.

BD Lactinex has been used as a probiotic to aid in digestion, to prevent diarrhea, and to relieve symptoms of irritable bowel syndrome. This medicine may work by helping the body maintain normal consistency of bacteria in the stomach and intestines.

BD Lactinex has not been approved by the FDA to treat any disease, and it should not be substituted for prescription medications.

BD Lactinex is often sold as an herbal supplement. There are no regulated manufacturing standards in place for many herbal compounds and some marketed supplements have been found to be contaminated with toxic metals or other drugs.
