Probiotic

Bifidobacterium lactis

Bifidobacterium lactis is commonly classified as Bifidobacterium animalis subsp. lactis. It is comparatively resilient during manufacturing and ferments carbohydrates through the bifid shunt.

It contributes to multi-strain probiotic blends that support normal digestive balance and gut microbial diversity.

In everyday life, Bifidobacterium lactis supports a more comfortable digestive rhythm and a balanced gut environment as part of a multi-strain probiotic routine.

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

Ingredient overview

What it is

Bifidobacterium lactis is commonly classified as Bifidobacterium animalis subspecies lactis. It is comparatively resilient during manufacturing and ferments carbohydrates through the bifid shunt.

  • Scientific identity: Bifidobacterium lactis; scientific identity: Bifidobacterium animalis subspecies lactis.
  • How it works: Active in the colon: Like all bifidobacteria it is a colon organism, fermenting carbohydrate through the genus-specific bifid shunt. Produces acetate and lactate: Those acids lower local pH, and the population is cleared over days once intake stops.
  • Primary function: It contributes to multi-strain probiotic blends that support normal digestive balance and gut microbial diversity.
  • What it supports: Bifidobacterium lactis supports a more comfortable digestive rhythm and a balanced gut environment as part of a multi-strain probiotic routine.
  • 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 lactis for a clearly defined role within a thoughtfully balanced formulation.

  • Formulation purpose: It contributes to multi-strain probiotic blends that support normal digestive balance and gut microbial diversity.
  • Used in: CARPEDIEM HappyGut 70B Probiotic and CARPEDIEM HappyGut 140B Probiotic.
  • Works alongside: Bifidobacterium lactis complements Bifidobacterium longum, Lactobacillus acidophilus and Lactobacillus rhamnosus to support everyday digestive wellness and complementary probiotic activity.
  • Meaningful contribution: Bifidobacterium lactis supports a more comfortable digestive rhythm and a balanced gut environment as part of a multi-strain probiotic routine. Contributes to a balanced intestinal environment within a multi-strain probiotic blend.
  • Quality and scientific context: Effects depend on the exact bacterial strain, viable colony-forming units and appropriate storage conditions throughout shelf life. 1 ingredient-specific study is included because the research reports a relevant benefit.

Ingredient intelligence

How it works

The bifidobacterium that copes with oxygen better than the rest of its genus.

Step 01 / 04

Tolerates oxygen.

Most bifidobacteria are damaged by air. This one is not, which is why it survives manufacturing and storage far better.

Effect of the probiotic strain Bifidobacterium animalis subsp. lactis, BB-12, on defecation frequency in healthy subjects with low defecation frequency and abdominal discomfort: a randomised, double-blind, placebo-controlled, parallel-group trial

British Journal of Nutrition

This large strain-specific trial assessed BB-12 in healthy adults with low bowel-movement frequency and abdominal discomfort. It provides direct human evidence for evaluating the strain, while outcomes should not be generalized to unidentified B. lactis cultures.

The Efficacy and Safety of Single-Strain Probiotic Formulations Containing Bifidobacterium lactis or Bacillus coagulans in Adult Patients with Irritable Bowel Syndrome: A Randomized Double-Blind Placebo-Controlled Three-Arm Interventional Trial

Nutrients

123 adults meeting Rome IV criteria were randomised across three arms comparing a single-strain Bifidobacterium lactis formulation, a single-strain Bacillus coagulans formulation and placebo over 12 weeks. Symptom severity was tracked on the IBS-SSS scale at weeks 4, 8 and 12 plus a 4-week follow-up. The two strains showed different profiles of effect, and both were well tolerated with no difference in adverse events versus placebo.

Lactobacillus acidophilus DDS-1 and Bifidobacterium lactis UABla-12 Improve Abdominal Pain Severity and Symptomology in Irritable Bowel Syndrome: Randomized Controlled Trial

Nutrients

A randomised, double-blind, placebo-controlled multi-centre study in 330 adults aged 18 to 70 with IBS by Rome IV criteria. Participants received placebo, L. acidophilus DDS-1 or B. lactis UABla-12, each at 10 billion CFU/day, for six weeks. Both probiotic groups showed improvement over placebo on the Abdominal Pain Severity numeric rating scale and on IBS Symptom Severity Scale sub-scores covering abdominal pain, distension, bowel habits and quality of life, with normalisation of stool consistency.

The effect of probiotics on functional constipation in adults: a systematic review and meta-analysis of randomized controlled trials

American Journal of Clinical Nutrition

A systematic review and meta-analysis of 14 eligible trials covering 1,182 participants, yielding 16 separate interventions including seven of Bifidobacterium lactis alone and four of Lactobacillus casei Shirota. Overall, probiotics reduced whole gut transit time by 12.4 hours and increased stool frequency by 1.3 bowel movements per week, with the effect on frequency and consistency significant for B. lactis. No serious adverse events were reported.
