In this episode of the Optispan Podcast, Dr. George Sutphin delves into biological age testing, with a focus on epigenetic and glycan-based assessments. The discussion covers the accuracy, significance, and implications of these tests in distinguishing biological age from chronological age. Key points include the limitations of current biomarkers, the influence of lifestyle on ageing measures, and the complexities of interpreting results.

This episode, featuring Dr. George Sutphin, dives into biological age testing. Key points include the limitations of current biomarkers, the influence of lifestyle on ageing measures, and the complexities of interpreting results. Dr. Sutphin highlights the importance of scientific validation and cautions against overstated marketing claims in the field of biological age testing. The discussion covers the scientific, practical, and emotional aspects of using these tests to explore ageing and health metrics.

• Biological Age Tests Overview: Dr. George Sutphin and the host discuss epigenetic and glycan age tests, examining how these tests aim to measure biological ageing versus chronological ageing.
• Epigenetic Clocks: The conversation explores how epigenetic markers are used to predict biological age, their potential limitations, and the scientific debate over their accuracy and relevance.
• Glycan Age and Inflammation: Glycan-based tests are highlighted as tools to evaluate inflammation ("inflammaging"), though baseline glycan levels may be more influenced by genetics than lifestyle.
• Challenges in Interpretation: The episode emphasizes the variability in test results, the lack of validated biomarkers, and the challenge of determining actionable insights from these assessments.
• Psychological Impact: The discussion addresses how receiving unexpected results, such as a high biological age score, can affect emotions and decisions despite test limitations.
• Future of Biological Age Testing: The podcast underscores the need for scientific validation, mechanistic connections to health outcomes, and integration of multiple biomarkers to refine biological age assessments.
