BifidoBacterium Bifidum

Bifidobacterium bifidum occurs naturally in the human gut microbiome, is commonly used as a probiotic, and may provide a variety of benefits, including aiding vitamin K and B-complex vitamins production within the intestines, which are essential to human function.

Supplementing the diet with B. bifidum has been shown to improve digestion and boost immune function. B. bifidum promotes microbiota equilibrium and optimal digestion, creating an unfavorable environment for the production of histamine, a chemical responsible for triggering allergic reactions. In addition, B. bifidum may enhance the body's natural antibody immune response. These conclusions may indicate that B. bifidum can help fight intestinal pathogens, digestive irregularities, and histamine production, ultimately improving the body's immunity and reducing risk of allergic reactions.

One study revealed short-term supplementation with B. bifidum may result in restoration of balanced gastrointestinal (GI) tract microflora. In addition, notable improvements in alcohol-induced liver injury were seen with B. bifidum when compared to standard therapy alone.

Probiotics like B. bifidum can be particularly effective in diarrheal treatment, including infectious diarrhea and antibiotic associated diarrhea. Rebalancing the GI tract microflora with probiotic supplements can result in a decrease in stool frequency, fecal weight, and abdominal cramps.
