The probiotics Bifidobacterium animalis subsp. lactis BLa80 and Lacticaseibacillus rhamnosus LRa05 have potential to enhance infant health and development based on previous research conducted on human infants.
Bifidobacterium animalis subsp. lactis BLa80 was isolated from healthy breast milk samples.
Ten clinical studies have been conducted using this strain, including randomized, double-blind, placebo-controlled trials, involving over 700 clinical subjects, adults and children. Based on the results from these studies, functional benefits associated with ingestion of this probiotic include relief of diarrhea, relief of constipation, improved sleep quality, resistance to H. pylori infection, modulation of gut microbiota, promotion of infant growth and development, gestational diabetes management and emotional management.
Lacticaseibacillus rhamnosus LRa05 was isolated from healthy baby faeces. Six clinical studies have been conducted, involving randomized, double-blind, placebo-controlled studies using this strain, involving over 500 clinical subjects. Based on the results from these studies, functional benefits associated with ingestion of this probiotic include relief of diarrhea, relief of eczema, resistance to H. pylori infection, modulation of gut microbiota, promotion of infant growth and development, and gestational diabetes management.
This proposal describes a three-year collaboration with APC Microbiome Ireland, INFANT Research Centre and WeCare to conduct clinical studies to investigate the effects of probiotics (Bifidobacterium animalis subsp. lactis BLa80 and Lacticaseibacillus rhamnosus LRa050), compared to a placebo, on the growth of infants and toddlers and the development of their gut microbiota. The focus of this study is on infant growth and gut microbiota development in infants up to 6 months old.

Parallel
Placebo (maltodextrin)
Dietary supplementThis study will investigate the effects of probiotics (Bifidobacterium animalis subsp. lactis BLa80 or Lacticaseibacillus rhamnosus LRa05), versus a placebo (maltodextrin), on the growth of infants and the development of their gut microbiota. The primary focus is on infant growth and gut microbiota development in infants aged 0-6 months. Maltodextrin is white, powdery, almost flavourless starch that is used to mimic the probiotic powder.
Probiotic
Dietary supplementThis study will investigate the effects of probiotics Bifidobacterium animalis subsp. lactis BLa80, versus a placebo (maltodextrin), on the growth of infants and the development of their gut microbiota. The primary focus is on infant growth and gut microbiota development in infants aged 0-6 months.
Probiotic
Dietary supplementThis study will investigate the effects of probiotic Lacticaseibacillus rhamnosus LRa05, versus a placebo (maltodextrin), on the growth of infants and the development of their gut microbiota. The primary focus is on infant growth and gut microbiota development in infants aged 0-6 months.
Primary Objective
The primary aim is to describe the impact of supplementation with the probiotics LRa05 and BLa80 on the developing gut microbiota in infants aged 0-6 months. Gut microbiota structure will be analyzed following shotgun sequencing, including strain presence and persistence in the infant's gut during 0-6 months of age.
Secondary Outcome Measure - Infant length
To evaluate the impact of supplementation infant length. Length will be monitored by recording infant length (in cm) following the probiotic intervention.
Secondary Outcome Measure - Infant Weight
To evaluate the impact of supplementation infant weight. Weight will be monitored by recording infant weight (in kg) following the probiotic intervention.
Secondary Outcome Measure - Head circumference
To evaluate the impact of supplementation infant head circumference. Head circumference will be monitored by recording infant head circumference (in cm) following the probiotic intervention.
Secondary Outcome Measure - SCFA Analysis
To detect the levels of short-chain fatty acids (SCFAs) in the faecal samples following the probiotic intervention.
