'''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 web |title=Development and commercialisation of Fonterra's probiotic strains - ProQuest |url=https://www.proquest.com/openview/579abb839dcd5dd35e596821a0b6f2e9/1?pq-origsite=gscholar&cbl=36914 |access-date=2023-12-26 |website=www.proquest.com |language=en}}</ref><ref>{{Cite web |title=Google Scholar |url=https://scholar.google.com.pk/scholar?q=Development+and+commercialisation+of+Fonterra%E2%80%99s+probiotic+strains%E2%80%9D.+Aust+J+Dairy+Technol.+60,+173-182&hl=en&as_sdt=0&as_vis=1&oi=scholart |access-date=2023-12-26 |website=scholar.google.com.pk}}</ref> Probio DR10^TM~ 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.

Line 10:

Studies on Probio DR10^TM~ 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 Probio DR10^TM~ along with a prebiotic, in comparison to those who were administered a placebo.<ref name="Sazawal e12164">{{Cite journal |last=Sazawal |first=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. |date=2010-08-13 |editor-last=Belizan |editor-first=Jose M. |title=Prebiotic and Probiotic Fortified Milk in Prevention of Morbidities among Children: Community-Based, Randomized, Double-Blind, Controlled Trial |url=https://dx.plos.org/10.1371/journal.pone.0012164 |journal=PLoS ONEOne |language=en |volume=5 |issue=8 |pages=e12164 |doi=10.1371/journal.pone.0012164 |issn=1932-6203 |pmc=PMC29214052921405 |pmid=20730056}}</ref>

A separate RCT also showed that the supplementation of Probio DR10^TM~  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 |last=Hemalatha |first=R. |date=2014-01-10 |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 |url=https://journalejnfs.com/index.php/EJNFS/article/view/144 |journal=European Journal of Nutrition & Food Safety |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 |last=Gopal |first=Pramod K |last2=Prasad |first2=Jaya |last3=Gill |first3=Harsharnjit S |date= |title=Effects of the consumption of Bifidobacterium lactis HN019 (DR10TM) and galacto-oligosaccharides on the microflora of the gastrointestinal tract in human subjects |url=https://linkinghub.elsevier.com/retrieve/pii/S0271531703001349 |journal=Nutrition Research |language=en |volume=23 |issue=10 |pages=1313–1328 |doi=10.1016/S0271-5317(03)00134-9}}</ref><ref>{{Cite journal |last=Ahmed |first=M. |last2=Prasad |first2=J. |last3=Gill |first3=H. |last4=Stevenson |first4=L. |last5=Gopal |first5=P. |date=2007 |title=Impact of consumption of different levels of Bifidobacterium lactis HN019 on the intestinal microflora of elderly human subjects |url=https://pubmed.ncbi.nlm.nih.gov/17315077 |journal=The Journal of Nutrition, Health & Aging |volume=11 |issue=1 |pages=26–31 |issn=1279-7707 |pmid=17315077}}</ref><ref name=":3" />

Line 22:

Probio DR10^TM~ 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~ also helps regulate the host immune defence against pathogens.<ref name=":3" />

Line 28:

A 2010 study also found that combining Probio DR10^TM~ 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 Probio DR10^TM~ for 2 weeks alleviated constipation by reducing the gut transit time.<ref name=":1">{{Cite journal |last=Waller |first=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. |date= |title=Dose-response effect of Bifidobacterium lactis HN019 on whole gut transit time and functional gastrointestinal symptoms in adults |url=http://www.tandfonline.com/doi/full/10.3109/00365521.2011.584895 |journal=Scandinavian Journal of Gastroenterology |language=en |volume=46 |issue=9 |pages=1057–1064 |doi=10.3109/00365521.2011.584895 |issn=0036-5521 |pmc=PMC31717073171707 |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" />

Line 36:

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

Studies have shown that not all probiotics are equally effective.<ref name=":2">{{Cite journal |last=McFarland |first=Lynne V. |last2=Evans |first2=Charlesnika T. |last3=Goldstein |first3=Ellie J.

== Mechanism of action ==

Line 49:

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" />

These junctions are vital for controlling the permeability of the epithelium.<ref name=":0" /> Any changes in their function can lead to increased inflammation, and subsequently, the development of diseases.<ref name=":0" /><ref>{{Cite journal |last=EFSA Panel on Nutrition, Novel foods and Food Allergens (NDA) |last2=Turck |first2=Dominique |last3=Castenmiller |first3=Jacqueline |last4=De Henauw |first4=Stefaan |last5=Hirsch‐Ernst |first5=Karen Ildico |last6=Kearney |first6=John |last7=Knutsen |first7=Helle Katrine |last8=Maciuk |first8=Alexandre |last9=Mangelsdorf |first9=Inge |last10=McArdle |first10=Harry J |last11=Naska |first11=Androniki |date= |title=Bifidobacterium animalis subsp. lactis Bi‐07 contributes to increasing lactose digestion: evaluation of a health claim pursuant to Article 13(5) of Regulation (EC) No 1924/2006 |url=http://doi.wiley.com/10.2903/j.efsa.2020.6198 |journal=EFSA Journal |volume=18 |issue=7 |doi=10.2903/j.efsa.2020.6198 |pmc=PMC73881457388145 |pmid=32742434}}</ref>
