Bifidus Actiregularis is a brand name used in some parts of the world to market a specific strain of Bifidobacterium Lactis.
The name Bifidus Actiregularis is the trademark of Danone (Dannon in the USA) Company’s strain of bifidobacterium animalis used to enrich their Activia line of products in places like Belgium, Chile, France, Greece and the Netherlands.
Dannon’s yogurt products are used by the consumer to improve digestive health and bowel regularity.
The full classification for Dannon’s bacterial strain is B. animalis subsp. lactis strain DN-173010. Dannon markets their probiotic bacteria under various names, depending on the part of the world in which it is found.
For example, in the USA and Mexico, it is labeled as Bifidus Regularis; in Canada the name is B. L. Regularis; in Brazil it is called Danregularis; and in the UK it is marketed as Bifidus Digestivum.
These are all the same bacterial microorganism.

Probiotic strains of bifidobacterium lactis, also referred to as B. lactis, have multiple probiotic properties, all of which are shared by Dannon’s strain, Bifidus Actiregularis.
B. lactis is a hardy microbe which is able to withstand the extreme environment of the early gastrointestinal system, allowing it to reach and effectively colonize the gut and colon.
When foods like yogurt are ingested, they are broken down in a myriad of ways, beginning with the enzymes within our mouths.
As they pass through the digestive tract, they get broken down in smaller and smaller compounds, providing the appropriate microorganisms, acids and enzymes are available. These bioactive molecules are absorbed by our body to be used for processes necessary to sustain health and wellbeing.
Bifidus Actiregularis, and other probiotic B. lactis bacteria, if introduced in adequate quantities to the human gastrointestinal system, participate in colonizing the gut and colon to such extent that unfriendly bacteria are unable to gain a foothold.
In addition, in the colon, B. lactis bacteria work to break down some substances which were unable to be broken down in the earlier passages of the GI tract.
Bifidus Actiregularis works to improve slower digestive transit, meaning the time it takes for food to pass from the time it enters the mouth until the time it leaves the body.
Dannon shows that by eating at least three servings of their probiotic Activia yogurt products each day, a significant number of people are able to see an improvement in digestive transit times.
Benefits of Bifidus Actiregularis Yogurt
The average adult human body has over three pounds of microorganisms within it’s systems at any point in time. Probiotic microorganisms are those which confer a beneficial effect on their human host.
Many probiotics work symbiotically to produce the heath-conferring effects like those seen with Danone’s Bifidus Actiregularis.
Many people report bowel frequency changes after just four weeks of eating Activia yogurt products. In many cases, both constipation and diarrhea can be mitigated and modulated through the proper administration of probiotic supplements.
This is accomplished by restoring a healthy balance to the microflora throughout the microbiome. Pathogenic bacteria are killed or downgraded to minority status, while helpful bacteria take over and re-populate the intestinal lumen, stomach and colon.
Bifidus Actiregularis has also been shown to relieve some symptoms experienced with Irritable Bowel Syndrome (IBS). In particular, bloating and abdominal distention were noticeably decreased in a good number of women participating in a 2009 study.
Using Probiotic Yogurt vs. Supplements
Daily supplementation of Bifidus Actiregularis, or other probiotic strain of B. lactis, can be done through milk-based products like Activia yogurt, or by taking B. lactis supplements which are available in pill, capsule or tablet form.
Activia Yogurt contains somewhere between 100 million CFUs (colony forming units) to over 6 billion CFUs. Dannon Company doesn’t offer a breakdown of the various bacteria included in their products.
This is a point of concern for many consumers as this information is necessary to determine whether side effects may occur and the specific benefits of the strains included. Probiotic supplements may offer more control by allowing users to select the strains known to provide the health-boosting benefits they require.
Bifidus Actiregularis Side Effects
Bifidus Actiregularis is considered safe and beneficial for most individuals. Questions or concerns should be addressed to a personal healthcare provider.
B. lactis strains are found naturally in foods we eat. For health conscious people, this is another advantage which probiotics have over pharmaceutical drugs, most of which come with a long list of side effects.
Individuals whose immune system has been weakened should talk with their doctor before taking probiotics. Also, those with short bowel syndrome are cautioned to speak with their doctor before starting a probiotic regimen.
Bifidus Actiregularis is thought to be safe for healthy pregnant women and nursing mothers, but as with all supplements or medications, talk with your doctor to ascertain its safety.
Conclusion
Bifidus Actiregularis is the name which Danone Company has given its proprietary strain of B. lactis bacteria. It is the strain of probiotic bacteria used to enrich their line of Activia food products.
Bifidus Actiregularis can be beneficial if at least three servings of Activia yogurt are eaten regularly each day.
For those who are lactose intolerance, using a Bifidobacterium Lactis capsule or pill can confer the same benefits without requiring the consumption of yogurt.
