'''Probiotic Probio DR10''', is the consumer brand name for a probiotic strain developed by Fonterra Research Development Centre (FRDC), patented and commercialised in the 1990s following the screening of over 2,000 strains.<ref>{{cite journal |last1=Gopal |first1=Pramod |last2=Dekker |first2=James |last3=Prasad |first3=Jaya |last4=Pillidge |first4=Christopher |last5=Delabre |first5=Marie-Laure |last6=Collett |first6=Michael |title=Development and commercialisation of Fonterra's probiotic strains |journal=Australian Journal of Dairy Technology |date=2005 |volume=60 |issue=2 |pages=173–182 |id={{INIST|17047956}} {{ProQuest|199361400}} }}</ref> Probio DR10^TM~It is also known under the name of the ingredient trade mark HN019*.

The Probio DR10^TM~ strain is available in a range of finished formats, providing it with great potential to be applied across the food and beverage, dietary supplement, and pharmaceutical industries.<ref name=":3" />''Bifidobacterium lactis'' is found in Anmum^TM Materna and Anmum^TM Essential Gold in the Malaysian market.

== Benefits of Probio DR10^TM~ ==

Studies on Probiothe DR10^TM~strain indicate positive effects on various aspects of the digestive system.<ref name=":3" /> These include:

===Immune system support===

Probio DR10^TM~ demonstrated extensive immune-stimulating effects in animal models as well as healthy adult and elderly clinical studies. In a randomised controlled trial (RCT) conducted with children aged 1 to 3 years, it was found that the incidence of high fever and severe acute lower respiratory infections was reduced by 5% and 35% respectively, in children who received Probiothe DR10^TM~strain along with a prebiotic, in comparison to those who were administered a placebo.<ref name="Sazawal e12164">{{cite journal |last1=Sazawal |first1=Sunil |last2=Dhingra |first2=Usha |last3=Hiremath |first3=Girish |last4=Sarkar |first4=Archana |last5=Dhingra |first5=Pratibha |last6=Dutta |first6=Arup |last7=Verma |first7=Priti |last8=Menon |first8=Venugopal P. |last9=Black |first9=Robert E. |title=Prebiotic and Probiotic Fortified Milk in Prevention of Morbidities among Children: Community-Based, Randomized, Double-Blind, Controlled Trial |journal=PLOS ONE |date=13 August 2010 |volume=5 |issue=8 |pages=e12164 |doi=10.1371/journal.pone.0012164 |doi-access=free |pmc=2921405 |pmid=20730056 |bibcode=2010PLoSO...512164S }}</ref>

A separate RCT also showed that the supplementation of Probio DR10^TM~the strain in children aged 2 to 5 years reduced the incidence of diarrhoea and fever by 16.1% and 12.7% respectively during the rainy season.<ref>{{cite journal |last1=Hemalatha |first1=R. |title=A Community-based Randomized Double Blind Controlled Trial of Lactobacillus paracasei and Bifidobacterium lactis on Reducing Risk for Diarrhea and Fever in Preschool Children in an Urban Slum in India |journal=European Journal of Nutrition & Food Safety |date=10 January 2014 |volume=4 |issue=4 |pages=325–341 |doi=10.9734/EJNFS/2014/8280 }}</ref>

===Modulation of intestinal microbiota===

Probio DR10^TM~ may increase the population of beneficial gut microflora of ''Bifidobacterium'' and ''Lactobacillus''.<ref>{{cite journal |last1=Gopal |first1=Pramod K |last2=Prasad |first2=Jaya |last3=Gill |first3=Harsharnjit S |title=Effects of the consumption of Bifidobacterium lactis HN019 (DR10TM) and galacto-oligosaccharides on the microflora of the gastrointestinal tract in human subjects |journal=Nutrition Research |date=October 2003 |volume=23 |issue=10 |pages=1313–1328 |doi=10.1016/S0271-5317(03)00134-9 }}</ref><ref>{{cite journal |last1=Ahmed |first1=M. |last2=Prasad |first2=J. |last3=Gill |first3=H. |last4=Stevenson |first4=L. |last5=Gopal |first5=P. |title=Impact of consumption of different levels of Bifidobacterium lactis HN019 on the intestinal microflora of elderly human subjects |journal=The Journal of Nutrition, Health & Aging |date=2007 |volume=11 |issue=1 |pages=26–31 |id={{INIST|18554996}} {{ProQuest|222242470}} |pmid=17315077 }}</ref><ref name=":3" />

ProbioThe DR10^TM~strain has also been shown to help maintain a healthy/normal gut microbiota against the ageing process by competing with and excluding harmful pathogens, operating at both taxonomical and functional levels.<ref name=":3" />

===Maintenance of intestinal barrier functions===

Probio DR10^TM~ helps maintain the integrity of the gut epithelium, which is a layer of cells lining the inner surface of the intestine.<ref name=":3" /> Probio DR10^TM~It also helps regulate the host immune defence against pathogens.<ref name=":3" />

A 2010 study also found that combining Probiothe DR10^TM~strain with an oligosaccharide prebiotics results in a decrease in the incidence of dysentery.<ref name="Sazawal e12164"/>

===Regulation of gut motility and improvement of gastrointestinal symptoms===

Probio DR10^TM~ has demonstrated a positive effect on individuals suffering from constipation.<ref name=":3" /> A New Zealand study involving 100 adults with functional gastrointestinal symptoms showed that the supplementation of Probiothe DR10^TM~strain for 2 weeks alleviated constipation by reducing the gut transit time.<ref name=":1">{{cite journal |last1=Waller |first1=Philip A |last2=Gopal |first2=Pramod K. |last3=Leyer |first3=Gregory J |last4=Ouwehand |first4=Arthur C. |last5=Reifer |first5=Cheryl |last6=Stewart |first6=Morgan E. |last7=Miller |first7=Larry E. |title=Dose-response effect of Bifidobacterium lactis HN019 on whole gut transit time and functional gastrointestinal symptoms in adults |journal=Scandinavian Journal of Gastroenterology |date=September 2011 |volume=46 |issue=9 |pages=1057–1064 |doi=10.3109/00365521.2011.584895 |pmc=3171707 |pmid=21663486 }}</ref>

Reductions in the frequency of other functional gastrointestinal symptoms, including vomiting, regurgitation, abdominal pain, nausea, gurgling, irregular bowel movements, diarrhoea and flatulence were also observed in the same study.<ref name=":1" />

Probio DR10^TM~ may potentially divert colon fermentation towards the production of non-gaseous end products.<ref name=":3" /> This characteristic of Probiothe DR10^TM~strain may support tolerance for the fermentation of oligosaccharides within the body, which aligns with clinical findings that Probio DR10^TM~it reduces the occurrence of flatulence.<ref name=":3" />

===Support for digestion===

The fermentation of Probio DR10^TM~ produces lactate and short-chain fatty acids (SCFAs) such as acetate, indicating their potential involvement in the digestion of dietary elements, without distinguishing between their source, whether it be carbohydrates or proteins.<ref name=":3" />

===Not all probiotics are the same===

== Mechanism of action ==

Probio DR10^TM~ demonstrates an excellent ability to adhere to epithelial cells, a strong capacity to endure and survive in a low pH environment, resistance to bile salts as well as the ability to modulate the immune response.<ref name=":0" />

Studies indicate that this strain acts on intercellular junctions, especially tight junctions.<ref name=":0" /> Tight junctions are situated in the most apical part of the cell and consist of two key proteins, claudin and occludin.<ref name=":0" /> These proteins play a crucial role in establishing the epithelial barrier, which acts as a safeguard against the entry of macromolecules, including lipids and proteins.<ref name=":0" />

The China National Center for Food Safety Risk Assessment (CFSA) has also approved the use of ''B. lactis'' in food for the general and paediatric population.<ref>{{Cite web |title=China National Center for Food Safety Risk Assessment |url=http://www.cfsa.net.cn:8033/UpLoadFiles/news/upload/2021/2021-10/23c78b5e-5a92-43a5-927b-ef15ada6bda9.pdf }}</ref>
