Partnering with top universities, we’ve built the largest glycan research program in the world, discovering how these molecules reveal deep insights about health, aging, and resilience.

ANALYZING GLYCANS

We Are Unique In What We Do

GlycanAge is the only biological age test in the world that measures chronic inflammation by analyzing glycans, a powerful but often overlooked layer of biology that influences immune function, and overall health.

Backed by 30+ years of research, GlycanAge sits at the frontier of personalized, preventative health, translating cutting-edge glycoscience into real-world insights you can act on.

LANGUAGE OF THE IMMUNE SYSTEM

What Are Glycans Anyway?

Glycans are complex sugars and one of life’s four essential building blocks, alongside proteins, lipids, and nucleic acids. They coat every cell surface and are attached to over half of all human proteins, regulating immunity, cell signaling, and development.

At GlycanAge, we study a specific group of glycans on Immunoglobulin G (IgG), the main protective antibody. These glycans act like switches, turning immune activity up or down, and are closely linked to inflammation and long-term health.

Unlike standard tests that detect issues only after their onset, glycans reveal early signs of immune imbalance and chronic inflammation, well before symptoms appear. That’s what makes them the foundation of true prevention.

A WINDOW INTO INFLAMMATION

What Do Glycans Reflect?

IgG glycans are the only biomarker that accurately reflects chronic inflammation—a key hallmark of aging and an early sign of immune imbalance.

As we age, immune regulation declines, leading to persistent, low-grade inflammation, or “inflammaging.” This drives age-related diseases and is strongly influenced by lifestyle factors like stress, poor sleep, poor diet, and inactivity.

Chronic inflammation captures the combined influence of genetics, epigenetics, environment, and lifestyle—all in one measurable signal. That’s why it’s one of the most powerful indicators of biological age and future health risk.

IgG glycans are the only way to accurately measure chronic inflammation, offering a unique, early, and actionable window for prevention.

MEASURING IMMUNE RESILIENCE

How Do We Determine Biological Age?

Everyone has their unique IgG glycome—the collection of glycans attached to IgG antibodies.

While we share the same glycan types, the ratios of these glycans vary from person to person. In youth, anti-inflammatory glycans dominate, but with aging, disease, and unhealthy habits, this balance shifts toward pro-inflammatory glycans.

By measuring the balance between pro- and anti-inflammatory glycans, we can determine a person’s biological age, viewed through the lens of the immune system.

GLYCOSYLATION

Glycans Make Complex Life Possible—And Functional

Glycosylation, the addition of glycans to proteins, is a post-translational modification, meaning glycans are added after the protein is formed.

The addition of different glycans to the same protein creates diverse glycoproteins, expanding the functional diversity encoded by our genes.

BIOLOGICAL AGE

What is Biological Age?

Biological age measures how your body is aging at a molecular level—often significantly different from your chronological age. Different tests assess it by focusing on different systems:

  • Epigenetic clocks track DNA methylation
  • Telomere tests measure cellular wear and tear
  • Metabolomic and proteomic tests track circulating molecules

Among the 12 hallmarks of aging, chronic inflammation (inflammaging)—is one of the most critical and reversible drivers.

GlycanAge measures IgG glycans, the only biomarker that accurately reflects chronic inflammation, offering one of the clearest, most actionable views of how fast you’re truly aging.

OUR AGING MODEL

The Glycan Clock of Aging

The glycan clock of aging is a scientifically validated model that measures biological age by analyzing changes in the glycosylation patterns of IgG antibodies. These patterns shift predictably with age and reveal how well your body is managing chronic inflammation.

Built on over 30 years of research and validated on more than 300,000 samples across diverse populations, it’s grounded in one of the world’s largest aging biology datasets and reflects true biological mechanisms, not just correlations.

Unlike epigenetic clocks, which measure passive DNA changes, the glycan clock captures a functional, dynamic process. That means it not only tracks aging but can also be actively influenced through lifestyle changes or medical interventions.

Each chart has two lines—green for males and red for females—displaying changes in glycosylation patterns from age 20 to 80. The charts illustrate predictable shifts with age as described in the text explaining the Glycan Clock of Aging.

THE ANALYSIS PROCESS

How Your Biological Age is Calculated

We analyze your blood sample through a five-step lab process. Starting with the isolation of key antibodies, we release and label the attached sugar structures (glycans), then measure and interpret them to calculate your biological age.

1

IgG Isolation

We isolate a specific type of antibody (IgG) from the blood sample.

2

Glycan Release

We then release the glycans (sugar chains) that are attached to your IgG antibodies.

3

Fluorescent Labeling

The released glycans are labeled with a fluorescent dye, which allows them to be detected by our instruments.

4

Measuring Glycans

We separate and measure the labelled glycans to determine the quantity of each type.

5

Calculating Your Result

Finally, we compare your glycan profile to a large reference database to quantify your body's biological age.
