Bifidobacteria & fibre
Bifidobacterium lactis
BB-12® is an established and incredibly well researched live culture. In fact, a count of the clinical studies on this strain reveals that it's the single most researched strain of the entire Bifidobacteria genus - a significant genus, predominantly found in the large intestine. Bifidobacterium lactis BB-12 is the most well research strain for constipation, but also has significant research in immune system modulation too.

Research on the probiotic strain in Bifidobacteria & fibre (For maintaining regularity)

A recent clinical trial, one of the largest ever to investigate a probiotic, provides more evidence in support of the use of Bifidobacterium lactis BB-12® in those with constipation specifically. The B. lactis BB-12 strain was put to the test in a research project that used over 1,200 participants from all over Europe, including France, the UK and Germany. The subjects were selected from a volunteer database, each of which were healthy and had never previously been diagnosed with acute digestive dysfunction, but had reported symptoms of low defecation frequency and abdominal discomfort.


The volunteers were split into 3 groups. The first received 1 billion dose of B. lactis BB-12 once daily. The second group received 10 billion dose of B. lactis BB-12 once daily, and the third group received placebo. The groups were tested for a period of 4 weeks.

Results showed that B. lactis BB-12 should certainly be considered as part of a solution to improve bowel regularity. The 1 billion B. lactis BB-12 group revealed the most statistically impressive result, improving defecation frequency from 3 days a week to 4.5 days a week.

"Once again, it is confirmed that the BB-12 probiotic strain can bring significant gastrointestinal benefits to those who experience digestive issues." Mikkel Jungersen, Scientific Advisor, HHN, Chr. Hansen

  • Subject group of 20-39 year old women.
  • BB-12® shown to signficantly increase stool frequency in those with constipation.
  • Those in the non-constipated group did not have too many bowel movements. BB-12® was able to harmonise regularity of bowel movements.
