Understanding your biological age
GlycanAge measures the current state of your immune system to reveal how your lifestyle choices are reflecting in your biological age.
Rather than looking at static genetic markers, we analyze the N-glycosylation of immunoglobulin G (IgG), the most abundant antibody in your blood.
This process provides a snapshot of your body's ability to manage chronic inflammation, highlighting the gap between your chronological age and your biological health.
The most sensitive signal of inflammaging
Glycans reflect how your immune system is aging, capturing changes years before they appear in standard bloodwork.
30+ years of glycoscience
Grounded in the world's largest glycan dataset and the same methodology trusted by leading clinics and research institutions.
Done from home. Analyzed in a real lab.
Take a finger-prick sample at home, send it to our accredited lab, and track every result in your personal dashboard.

A 1:1 consultation helps you understand what your biological age reflects, and the lifestyle levers that can improve it.
