Glucose (Fasting)

Fasting Glucose measures blood sugar levels after an overnight fast (typically 8-12 hours). It reflects baseline glucose regulation. While standard guidelines define diabetes risk based on thresholds (e.g., prediabetes 100-125 mg/dL, diabetes ≥126 mg/dL), longevity experts emphasize maintaining levels in a tighter, lower optimal range (e.g., 70-90 mg/dL) for better metabolic health, reduced glycation, and potentially lower risk of age-related diseases. Continuous Glucose Monitoring (CGM) provides much richer data on glucose variability and post-meal responses.
