# Reuteri Reference > An overview of L. reuteri, where it is studied, and how a chewable oral probiotic like ProDentim describes it, with caveats on strain-level evidence. ## Guides - [What Lozenge Studies on L. reuteri Do and Do Not Cover](https://lactobacillus-reuteri-overview.basavugu.workers.dev/lactobacillus-reuteri-lozenge-studies/): Lactobacillus reuteri lozenge studies test particular products, often alongside normal dental care, so they cannot be read as proof about any other probiotic. - [Not All L. reuteri Strains Behave Alike](https://lactobacillus-reuteri-overview.basavugu.workers.dev/reuteri-strains-differ/): A species name groups many different strains, and strains of the same species can behave differently, so reuteri strains differ in ways a label should spell. - [L. reuteri in Food and Supplements](https://lactobacillus-reuteri-overview.basavugu.workers.dev/reuteri-in-food-and-supplements/): Reuteri in food and supplements is not the same thing: some foods may contain lactobacilli but the strain and amount are rarely stated, while a supplement. - [How to Judge the Quality of Probiotic Research](https://lactobacillus-reuteri-overview.basavugu.workers.dev/oral-probiotic-research-quality/): When you read oral probiotic research quality claims, look at the design, the named strain, the people who took part and what was actually measured. - [Why Studies Test Probiotics as an Add-On to Dental Care](https://lactobacillus-reuteri-overview.basavugu.workers.dev/probiotics-as-add-on-to-dental-care/): Researchers usually test oral probiotics as an add-on to dental care because brushing, cleaning between teeth and professional visits are the established. ## About - [About Reuteri Reference](https://lactobacillus-reuteri-overview.basavugu.workers.dev/about/): not medical advice, how the site is funded and how guides are made ## Optional - [RSS feed](https://lactobacillus-reuteri-overview.basavugu.workers.dev/feed.xml)
