Precision probiotics supplement strategy in aging population based on gut microbiome composition.

Area of Science:

• Gerontology
• Microbiology
• Immunology

Background:

• Age-related chronic diseases necessitate novel management strategies.
• The gut microbiota's composition and function change significantly with aging.
• These aging-related alterations in gut microbiota can impact health and disease progression.

Purpose of the Study:

• To investigate the potential of personalized probiotic supplements in older adults.
• To analyze gut microbiota composition and its association with health parameters in aging individuals.
• To identify specific microbial signatures that could be targeted by probiotics.

Main Methods:

• Metagenomic sequencing was employed to analyze the gut microbiota of 297 older adults.
• Microbial signatures, including Lactobacillus and Bifidobacterium, were identified.
• Associations between microbial profiles and population characteristics, cognitive function, and neuroimaging were explored.

Main Results:

• Distinctive Lactobacillus and Bifidobacterium patterns were observed in the gut microbiota of older adults.
• Probiotic patterns correlated with demographic factors, microbial diversity, cognitive status, and neuroimaging findings.
• These findings suggest a basis for personalized probiotic interventions.

Conclusions:

• Tailored probiotic supplements, matched to individual gut microbiota profiles, represent a potential strategy for addressing age-related decline.
• The study provides evidence supporting the use of probiotics in older populations for targeted health benefits.
• Further longitudinal research with larger cohorts is needed to confirm the efficacy of precision probiotics in aging individuals.
