Serum metabolomic signatures associated with frailty-related phenotypes in a cohort of older people

Key Points

• Frailty-related phenotypes are linked to specific serum metabolomic signatures, indicating potential biomarkers.
• In older adults, metabolomic analysis revealed significant differences in 10 identified metabolites between frail and non-frail individuals.
• Observational analysis of serum samples from older adults highlighted the relationship between frailty and metabolic changes.
• These findings suggest that identifying metabolomic signatures may help in understanding aging and related health risks.
