A new study adds to growing evidence for the effectiveness of the probiotic bacteria B. infantis 35624 in people suffering from irritable bowel syndrome.
April is IBS Awareness Month in the United States, making this new probiotic review timely, and providing welcome news for those with irritable bowel syndrome (IBS).
IBS is one of the most common functional bowel disorders diagnosed by primary care physicians and gastroenterologists; and 70 percent of IBS sufferers do not seek medical treatment and continue to suffer from digestive upsets. This study provides strong evidence that B. infantis 35624 may provide relief to many and is a simple and cost effective therapy.
The review was undertaken by researchers at Northwestern University (Chicago, IL.) and University of Michigan (Ann Arbor, MI). It sought to determine the effectiveness of probiotics in the treatment of Irritable Bowel Syndrome (IBS) and found that Bifidobacterium infantis 35624 was the only probiotic strain out of 13 different individual strains or preparations reviewed to significantly improve symptoms of IBS, including abdominal pain, bloating and bowel movement difficulty. Bifidobacterium infantis 35624 is marketed as Bifantis® and can be found in a daily probiotic supplement by Procter & Gamble. The researchers reviewed 16 random-controlled-studies, evaluating the efficacy, safety and tolerability of probiotics in the treatment of IBS. With the exception of the Bifidobacterium infantis 35624 studies, researchers found the other trials did not use an appropriate study design and did not adequately report adverse events. The article was published on the American Journal of Gastroenterology website in advance of appearing in the publication's April 2009 issue1.
Irritable Bowel Syndrome affects one in five Americans and treatment options are limited. Darren. M Brenner, Division of Gastroenterology and Department of Internal Medicine, at Northwestern University and lead investigator of this study, hypothesized that alterations in gut microflora may contribute to the development of IBS symptoms, and believed these symptoms could be improved by probiotics. "Probiotics are gaining popularity for the treatment of multiple gastrointestinal disorders, including IBS," said Brenner, MD. "After assessment of the methodological and statistical designs of these studies, B. infantis 35624 was the only probiotic that showed repeated efficacy."
Clinical Evidence and Support for Bifantis Continues to Grow
Bifidobacterium infantis 35624, discovered in the early 1990s by microbiologists at Alimentary Health in Cork, Ireland in partnership with P&G, has been independently tested and evaluated in several clinical trials conducted with humans. This latest review provides continued clinical evidence of Bifantis efficacy in helping to manage a range of gastrointestinal issues including abdominal pain, bloating, constipation, diarrhea, gas and urgency. Bifantis efficacy data has been published or referenced in several medical journals, including the American Journal of Gastroenterology2 , Gastroenterology3 , New England Journal of Medicine4 , Public Library of Science (PLoS)5 and Nutrition in Clinical Practice6. Bifantis is found in the number one gastroenterologist recommended probiotic supplement in the United States7 .
Susan Abeln, Principal Scientist at Procter & Gamble said, "P&G has worked with Alimentary Health to study and develop a supplement with Bifantis because we firmly believe in the benefits of this strain for the millions of Americans struggling to manage digestive upsets each day. We're excited to make Bifantis available to consumers nationwide this spring."
Further credentialing the probiotic strain, P&G recently announced that Bifantis meets the probiotic guidelines established by The International Scientific Association for Probiotics and Prebiotics (ISAPP). These guidelines include five key criteria that consumers should consider when selecting a probiotic product - strain specificity, clinical proof, packaging, and the quality and quantity of probiotics in a product. Bifantis is proven to fully meet these guidelines, making it a good option for those who want to build and maintain a natural defense against abdominal discomfort and episodic digestive upsets such as constipation, diarrhea, urgency, gas and bloating.
Bifantis (Bifidobacterium infantis 35624) is a probiotic strain that can help strengthen the body's natural defenses and play an important role in basic digestion, proper metabolism and overall well-being. Bifantis is the only natural probiotic strain found in Align. Bifantis has clinically demonstrated that, when taken regularly, it can help promote normal digestive health. Capsules containing Bifantis deliver millions of good bacteria to the digestive system to restore intestinal balance and maintain normal digestive health.
