  • Sources:

    and his guests discuss several important blood markers for health and longevity. They highlight their significance, desired levels, and how they are categorized. Here’s a summary divided into respective categories:

    Cardiovascular Health

    1. Apolipoprotein B (ApoB):
      • Importance: Key marker of cardiovascular health, assessing the risk of atherosclerotic disease.
      • Desired Levels: Levels should be as low as possible, generally <60 mg/dL being optimal.

      • Category: Inflammation.
      • Details: Chronic inflammation can contribute to diseases like atherosclerosis, diabetes, and neurodegenerative diseases. 2

    Genetic and Disease Predictors

    1. Genetic Markers (e.g., APOE):
      • Importance: Helps in understanding genetic predisposition to diseases like Alzheimer’s.
      • Desired Levels: Not applicable as these are genetic variants.
      • Category: Genetic Testing.
      • Details: Certain genetic profiles can help predict the risk of neurodegenerative diseases and guide personalized preventive measures. 2

    Other Metabolic Factors

    1. HbA1c:
      • Importance: Long-term marker for blood glucose levels, reflecting average blood sugar over 2-3 months.
      • Desired Levels: <5.7% is normal. 5.7%-6.4% indicates pre-diabetes, and >6.5% indicates diabetes.
