Limosilactobacillus reuteri LR08 (formerly classified as Lactobacillus reuteri) Evidence & Research

What It Is

Lactobacillus reuteri LR08 is a probiotic strain of beneficial bacteria. In simple terms, it’s a friendly microbe studied for supporting immune balance and helping maintain a healthy microbial environment in the body.

LR08 is included in oral probiotic formulations to help support a balanced oral environment as part of a microbiome-friendly daily routine.

Designed to:

Support microbial balance and immune-related wellness pathways.

What Research Suggests

A randomized, double-blind, placebo-controlled clinical trial found that LR08 was safe for human use and significantly increased salivary IgA and IgM levels — markers associated with immune support — while also influencing gut microbiota diversity.

Laboratory studies evaluating LR08 show that the strain demonstrates probiotic characteristics such as adhesion ability and interaction with other microbes, which are important for microbial balance.

What This Means

The research suggests LR08 is a well-tolerated probiotic strain that may support immune balance and healthy microbial ecosystems. While its strongest evidence currently relates to immune and microbiome support rather than direct oral endpoints, maintaining microbial balance is foundational to whole-body health.

Evena's Use of Lactobacillus reuteri LR08

Evena includes LR08 to complement oral-targeted strains with broader microbiome and immune support, reinforcing the concept that oral health connects to whole-body wellness.
