Bifidobacteria Bifidum


B. Bifidum

Supplement Class

Lactic acid- and acetic acid-producing bacteria

Immune support

Your gut is home to about 80% of your immune system. Imbalanced amounts of good vs bad bacteria can cause a major dysfunction in how your immune system responds to viruses and bacteria. B. Bifidum is the most prevalent species in breastfed infants and plays an important role in the immune system by immunomodulating the intestinal barrier in the colon 

Other uses

This species is naturally occurring in the mouth and in the small intestine. It is used for milk fermentation, breaks down carbohydrates and inhibits the growth of pathogenic and putrefactive bacteria in the small intestine. It is resistant to both gastric acid and bile. It contains enzymes that facilitate the breakdown of milk proteins and polypeptides as well as gluten. It is helpful in treating diarrhea caused by antibiotics and viruses. It inhibits growth of E. coli, as well as being effective against urinary tract infections.

How it works

Bifidobacteria belong to a group of bacteria called lactic acid bacteria. Lactic acid bacteria are found in fermented foods like yogurt and cheese. Bifidobacteria are used in treatment as so-called "probiotics," the opposite of antibiotics. They are considered "friendly" bacteria and are taken to grow and multiply in areas of the body where they normally would occur. The human body counts on its normal bacteria to perform several jobs, including breaking down foods, helping the body take in nutrients, and preventing the take-over of "bad" bacteria. Probiotics such as bifidobacteria are typically used in cases when a disease occurs or might occur due to a kill-off of normal bacteria. For example, treatment with antibiotics can destroy disease-causing bacteria, but also normal bacteria in the GI (gastrointestinal) and urinary tracts. The theory is that taking Bifidobacterium probiotics during antibiotic treatment can prevent or minimize the death of good bacteria and the take-over by bad bacteria.


When taken by mouth: Bifidobacteria are LIKELY SAFE for healthy adults when taken by mouth appropriately. In some people, treatment with bifidobacteria might upset the stomach and intestine, causing diarrhea, bloating and gas.

Special Precautions & Warnings:

Pregnancy and breast-feeding: A specific strain of bifidobacteria, Bifidobacterium bifidum, is POSSIBLY SAFE when taken by mouth appropriately for 6 weeks while pregnant. There is not enough reliable information about the safety of taking other bifidobacteria strains if you are pregnant or breast-feeding. Stay on the safe side and avoid use.

Children: Bifidobacteria are LIKELY SAFE for heathy children when taken by mouth appropriately. Although there have been cases of blood infection with bifidobacteria in critically ill infants, these cases are rare.

Weakened immune system: There is some concern that "probiotics" might grow too well in people with a weak immune system and cause infections. Although this has not occurred specifically with bifidobacteria, there have been rare cases involving other probiotic species such as Lactobacillus. If you have a weakened immune system (e.g., you have HIV/AIDS or are undergoing cancer treatment), check with your healthcare provider before using bifidobacteria.

Blockage in the intestines: Two cases of blood infections have been reported for infants given bifidobacteria probiotics. In both cases, the infants had had stomach surgery. It's thought that the blood infections resulted from intestinal blockage caused by the stomach surgeries, which allowed the bifidobacteria to cross into the bloodstream. In one case, taking bifidobacteria after the intestinal blockage was corrected did not cause another blood infection. Therefore the risk of blood infections is not a concern for most infants taking bifidobacteria. But bifidobacteria should be used cautiously or avoided in infants with stomach or intestinal blockages.

Interactions with medications

Antibiotic drugs

Interaction Rating = Moderate Be cautious with this combination.

Talk to your health provider.

Antibiotics are used to reduce harmful bacteria in the body. Antibiotics can also reduce friendly bacteria in the body. Bifidobacteria are a type of friendly bacteria. Taking antibiotics along with bifidobacteria might reduce the effectiveness of bifidobacteria. To avoid this interaction, take bifidobacteria products at least two hours before or after antibiotics.
