The Claim

The DunedinPACE biomarker exhibits high test-retest reliability and can detect small but sustained changes in the pace of biological aging over a two-year period in healthy adults.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Description
1 study reviewed
In plain English

The DunedinPACE biomarker consistently measures biological aging rate in healthy adults and detects small but lasting changes in that rate over two years.

See the scientific wording

The DunedinPACE biomarker demonstrates high test-retest reliability and is capable of detecting small but sustained changes in biological aging pace over a two-year period in healthy adults.

Why this might work

Changes in the chemical tags on DNA in blood cells track how quickly the body's systems decline over time. These tags shift in response to long-term metabolic and inflammatory conditions, and their pattern allows scientists to measure the exact speed of aging. The pattern is stable enough to detect tiny changes even over two years.

  1. Study: Effect of long-term caloric restriction on DNA methylation measures of biological aging in healthy adults from the CALERIE trial

    This study showed that DunedinPACE could detect when people aged more slowly due to eating fewer calories — meaning it’s sensitive enough to notice tiny, real changes in aging over two years, even in healthy people.
