Introduction

Animal experiments have revealed that LRa05 has significant improvements in high-fat diet mice.

Inhibition of weight, blood lipid levels and lipid accumulation in liver cells and epididymal fat tissue of the high-fat diet group.

Remodeling of the gut microbiota, reducing the abundance of potentially pathogenic Streptococcus.

Lowering of blood and liver glucose levels, and promoting liver carbohydrate and energy metabolism.

LRa05 has the potential to lower blood lipid levels and promote fat metabolism

LRa05 intervention resulted in distinct separation in meta-bolic analysis, with increased levels of certain metabolites and decreased levels of others compared to the high-fat diet group.

Regulate intestinal flora

Regulates the transformation value of spleen lymphocytes, inflammatory factors, and intestinal short-chain fatty acids.

LRa05 inhibits the Streptococcus mutant bacteriostatic zone

Inhibit Pathogens

Use of LRa05 in the preparation of products inhibiting Helicobacter pylori and / or Streptococcus mutans

Use of a LRa05 in the preparation of formulations for improving irritable bowel syndrome

Reduce serum endotoxin and increase levels of anti-inflammatory factors, relieve oxidative stress

LRa05 may have potential as a therapeutic intervention for managing T2DM

LRa05 treatment efectively reduced FBG levels, improved alucose tolerance, decreased insulin levels. reduced insulin resistance, and increased hepatic glycogen levels in T2DM mice.

Weight Management

A probiotic that regulates the level of intestinal hormone GLP-1 and its application

Reduce the levels of serum ALT and AST in obese people

It significantly increases the expression of GLP-1 in small intestinal endocrine cells and the expression of GLP.1 in intestinal tissues of obese people

Reduce weight in obese people

Regulates the transformation value of spleen lymphocytes, inflammatory factors, and intestinal short-chain fatty acids in mice

Diarrhea in children is a digestive tract syndrome caused by multiple pathogens and factors, which is characterized by increased stool frequency and changes in stool consistency. lt is a commonly and frequently occurring disease in children and is easy to cause malnutrition and restricted growth and development in children. The present study showed that when compared with the children in control group, the use of ready to eat probiotic powder (LRa05)for one week can significantly improve the therapeutic efficacy of children with diarrhea, reduce the frequency of stools, improve the stool consistency and observe no obvious adverse reactions which indicating its safety and reliability.

Subjects

Dosage:Lactobacillus rhamnosus LRa05, 5 x 10⁹ CFU/ sachet, 2g/sachet

Effect of probiotic intervention on daily stool consistency

The total Bristol stool consistent score of daily stool of children in both groups decreased significantly with the extension of treatment time. There were also significant diferences in the total Bristol stool consistent score of daily stool between two groups, and the children in intervention group was significantly lower than that of children the control group.

Effect of probiotic intervention on the average Bristol consistency score of daily stool of children

This study showed that with the extension of treatment time, the average Bristol stool consistent score of daily stool of children in both groups decreased significantly. The Bristol stool consistency score of daily stool between two groups, that of children in intervention group was significantly lower than that of children the control group. There was also an interaction between treatment time and intervention mode.

Effect of probiotic intervention on daily stool frequency

With the extension of treatment time, the number of daily defecation decreased significantly in both groups. There was also a significant difference in the frequency of stools between intervention group and control group and the frequency of stools in the intervention group was signifi-cantly less than those of children in the control group. At the same time, there was an interaction between treat-ment time and intervention mode.
