The Secret to Living Past 100 May Be Hidden in Your Blood

Boston University researchers found centenarians have distinctive blood metabolite patterns, including higher bile acids and preserved steroids.

The study compared centenarians, their offspring, and controls, suggesting links between these profiles and healthier aging.

Researchers also built a metabolomic clock to examine biological age and survival risk.

The findings may help identify biomarkers and pathways relevant to exceptional longevity, but they do not prove cause and effect.
