How is GlycanAge different from other biological age tests?

Many biological age tests aim to estimate how old a person is biologically, but they differ significantly in what they measure and how useful they are in practice. Some tests, such as telomere length testing, reflect only a narrow aspect of aging and may offer limited value when it comes to guiding interventions. DNA methylation clocks can provide a strong overall estimate of biological age, but they often function as a “black box,” giving a number without clearly showing what may be driving the result or how to act on it.

GlycanAge focuses on the functional state of the immune system, which plays a central role in aging and chronic disease risk. Rather than acting only as a static estimate, it can behave as a dynamic health signal that may shift over time in response to meaningful interventions such as weight loss, hormonal optimization, or reducing chronic inflammation. This makes GlycanAge a more actionable tool for tracking change and supporting more informed decisions over time.
