BIOLOGICAL AGE TESTING
What Is Biological Age Testing?
Biological age testing estimates how your body is aging based on molecular markers linked to cellular, molecular, and systemic health. It reflects the state of key biological processes such as inflammation, immune activity, and metabolism.
Biological age can differ from chronological age and may change in response to lifestyle, health, and recovery, providing insight into the pace of biological aging. How lifestyle affects biological age and how inflammation and glycans affect aging are covered in our FAQ.

Who We Do Research With
What Accuracy Means
Biological age test accuracy refers to how reliably a test reflects biological processes associated with aging, and how consistently it produces similar results under the same conditions.

Validation vs Prediction
Validated tests, such as GlycanAge, are supported by research linking their markers to aging and health outcomes at a population level. This differs from predicting individual lifespan or disease, which is inherently uncertain.

Variability Over Time
Biological age can change due to lifestyle, illness, stress, or recovery. For this reason, trends across repeated tests are generally more informative than a single result.

BIOLOGICAL AGE INSIGHTS
What Biological Age Testing Can Tell You
Understanding Biological Aging
Biological age reflects how aging processes are unfolding within the body, based on biological signals associated with long-term health. It helps explain why aging can look different from one person to another.
Who Biological Age Testing Is For
Biological age testing is used across personal health, preventive care, and research settings to better understand how aging processes vary between individuals.
BIOLOGICAL AGE EVIDENCE
Is Biological Age Testing Clinically Proven?
Research-Backed Methods
Epigenetic (DNA Methylation) Tests
Observational vs Interventional Evidence
Interventional studies, which test how biomarkers respond to specific changes or interventions, are less common and continue to evolve. Together, these approaches support the use of biological age testing as a tool for understanding and tracking biological aging over time.

Biological Age Testing with GlycanAge
GlycanAge is a biological age test that focuses on immune system aging by analysing glycans, complex sugar structures attached to proteins in the blood. These glycan patterns reflect long-term changes in inflammation and immune function, both of which are closely linked to aging.
The approach is research-led, grounded in glycoscience and peer-reviewed studies. GlycanAge is designed to provide a stable, biology-based measure of aging over time.
