Probiotic

Bifidobacterium bifidum

Bifidobacterium bifidum uses specialised enzymes to break down certain complex carbohydrates near the intestinal lining. These breakdown products can also become available to other gut bacteria.

Its fermentation activity supports a diverse multi-strain probiotic formula and contributes to the broader gut microbial environment.

In everyday life, Bifidobacterium bifidum helps break down complex carbohydrates and contributes useful fermentation activity to a balanced gut environment.

Probiotic benefits are strain-specific. Verified strain identity, viable CFU and storage conditions are important quality considerations.

Ingredient overview

What it is

Bifidobacterium bifidum uses specialised enzymes to break down certain complex carbohydrates near the intestinal lining. These breakdown products can also become available to other gut bacteria.

  • Scientific identity: Bifidobacterium bifidum; scientific identity: Bifidobacterium bifidum, genus type species.
  • How it works: Works outside the cell: Unusually for the genus it releases enzymes that break down complex carbohydrates externally, so the freed sugars become available to neighbouring organisms as well. Ferments by the bifid shunt: The genus-specific route yields acetate and lactate; the population is cleared over days once intake stops.
  • Primary function: Its fermentation activity supports a diverse multi-strain probiotic formula and contributes to the broader gut microbial environment.
  • What it supports: Bifidobacterium bifidum helps break down complex carbohydrates and contributes useful fermentation activity to a balanced gut environment.
  • Important consideration: Effects depend on the exact bacterial strain, viable colony-forming units and appropriate storage conditions throughout shelf life.

Formulation rationale

Why we use it

CARPEDIEM selected Bifidobacterium bifidum for a clearly defined role within a thoughtfully balanced formulation.

  • Formulation purpose: Its fermentation activity supports a diverse multi-strain probiotic formula and contributes to the broader gut microbial environment.
  • Used in: CARPEDIEM HappyGut 70B Probiotic and CARPEDIEM HappyGut 140B Probiotic.
  • Works alongside: Bifidobacterium bifidum complements Bifidobacterium longum, Bifidobacterium breve and Bifidobacterium lactis to support everyday digestive wellness and complementary probiotic activity.
  • Meaningful contribution: Bifidobacterium bifidum helps break down complex carbohydrates and contributes useful fermentation activity to a balanced gut environment. Contributes compounds that may also become available to other beneficial gut bacteria.
  • Quality and scientific context: Effects depend on the exact bacterial strain, viable colony-forming units and appropriate storage conditions throughout shelf life. Research is shown only when an ingredient-specific study demonstrates a relevant benefit.

Randomised clinical trial: Bifidobacterium bifidum MIMBb75 significantly alleviates irritable bowel syndrome and improves quality of life - a double-blind, placebo-controlled study

Alimentary Pharmacology & Therapeutics

122 patients were randomised to receive either placebo or B. bifidum MIMBb75 once daily for four weeks, recording symptom severity daily on a seven-point Likert scale. The MIMBb75 group showed a significantly larger reduction in the global assessment of IBS symptoms than placebo. The strain was selected for its documented ability to adhere to human intestinal cell lines.

Heat-inactivated Bifidobacterium bifidum MIMBb75 (SYN-HI-001) in the treatment of irritable bowel syndrome: a multicentre, randomised, double-blind, placebo-controlled clinical trial

The Lancet Gastroenterology & Hepatology

443 patients with IBS were recruited across 20 German study sites and randomly assigned to placebo or non-viable heat-inactivated B. bifidum MIMBb75 at 1 billion cells once daily. The composite primary endpoint was reached by 34% of the probiotic group versus 19% of placebo (risk ratio 1.7). No serious adverse events occurred in the treatment group. This is one of the largest single-strain Bifidobacterium trials in IBS.

Impact of a probiotic product on bowel habits and microbial profile in participants with functional constipation: A randomized controlled trial

Journal of Digestive Diseases

94 otherwise healthy adults aged 18 to 65 with symptoms of functional constipation were randomised to placebo or a four-strain product at 15 billion CFU/day containing Lactobacillus acidophilus DDS-1, Bifidobacterium lactis UABla-12, Bifidobacterium longum UABl-14 and Bifidobacterium bifidum UABb-10 for four weeks. The probiotic group showed faster normalisation of stool frequency and consistency, with most participants reaching a normalised profile after one week.
