The method & evidence

CAge correlation / limited outcomes

Provisional method assessment: the cited primary study links IgG glycan patterns with age and physiological measures. This entry does not establish independently replicated outcome validation of the current commercial score.

Our grade evaluates the measurement method. It does not grade customer service, personal results or whether buying the product improves health. Read the framework.

Potential strengths

  • Explores a different biological layer from methylation tests.

Useful to explore for

  • Understanding glycan-based measurements

Important limitations

  • Immune-related glycan patterns do not describe every dimension of aging.

Not ideal for

  • People expecting a DNA-methylation age or a disease diagnosis

Strengths, limitations and use cases are editorial interpretations of the cited information.
