Clinical Profile

Bifidobacterium bifidum is one of the most common probiotic bacteria found in the mammalian gut. It plays a critical role in maintaining the mucosal barrier of the intestine, digesting complex carbohydrates, and modulating the local immune system to prevent pathogenic overgrowth.

Clinical Summary

Clinically supported for aiding in the management of irritable bowel syndrome (IBS), supporting immune response, and improving overall digestive regularity when used alongside other Lactobacillus and Bifidobacterium strains.

Dosage Guidelines

Typically dosed between 1 billion and 10 billion CFUs daily, often within a multi-strain functional formula.

Safety & Side Effects

Extremely well tolerated. May cause temporary mild bloating or gas during the first few days of supplementation as the gut microbiome adjusts.

Known Interactions

Antibiotics will drastically reduce the efficacy and survival of this strain; oral doses must be separated by at least 2 to 4 hours.
