What is the Longevity Research Library?

The Longevity China Research Library curates recent peer-reviewed studies on longevity, nutrition, exercise, sleep, and supplements. Each study is rated by evidence strength: Strong, Moderate, or Preliminary.

How are evidence levels determined?

Evidence levels are based on study type (meta-analysis, RCT, cohort study), sample size, journal impact factor, and reproducibility of findings.

56 studies

Frailty Markers Predict 20-Year Death Risk in Older Chinese Adults

In about 4,000 older Hong Kong adults tracked for nearly two decades, frailty measures strongly predicted who would die and from what cause. Being frail was linked to a 66% higher risk of death compared to being fit. Adding blood-based markers like inflammation and kidney function to frailty scores slightly improved predictions. One surprise: none of the biological aging markers predicted cancer deaths specifically.

New Aging Clocks Built From Histone Marks Work Across Species

Researchers built 36 new biological aging clocks using histone modifications (chemical tags on the proteins that package DNA) instead of the usual DNA methylation approach. These clocks worked well across six tissue types and could detect accelerated aging in leukemia samples and age reversal after treatments. One surprising finding: many aging-related changes peak at midlife rather than climbing steadily. The approach even worked in fruit flies, which lack DNA methylation entirely.

Red Blood Cell Proteins Can Track Biological Aging and Predict Health a Decade Later

Researchers built a protein-based aging clock from the red blood cells of over 13,000 blood donors. People with conditions like G6PD deficiency and sickle cell trait showed accelerated molecular aging. Iron supplementation appeared to reverse some of that acceleration. The molecular age scores predicted real-world outcomes like hemolysis and donor activity over a 12-year follow-up.
