Estimated Average Glucose (eAG)
Routine annualalso eag, average glucose
What it isA simple back-translation of A1c into a single average glucose number using a fixed equation. The body doesn't measure it directly — the lab calculates it from A1c.
DoesRestates the same A1c information in the same units a continuous glucose monitor would show.
GoodA low eAG mirrors a low A1c — stable, low-amplitude glucose handling and long-term metabolic health.
BadHigh eAG, like high A1c, predicts cardiovascular disease, dementia, retinopathy, neuropathy, and accelerated aging.
- Standard
- Derived from A1c — 5.7% A1c ≈ 117 mg/dL.
- Optimal
- 85–100 mg/dL (lower is good)
- Modifiers
- Same modifiers as A1c — anemia, hemoglobinopathies, red cell turnover.
How to optimize
- Lifestyle
- Resistance training, Zone 2 cardio, sleep, post-meal walking, time-restricted eating.
- Diet
- Whole-food low-glycemic eating; protein and fiber first; cut sugar and refined grains.
- Supplements
- Berberine (500mg 3×/day), magnesium glycinate (300mg/day), inositol (2g 2×/day), alpha-lipoic acid (600mg/day).
- Peptides
- GLP-1 agonists (semaglutide, tirzepatide, retatrutide), MOTS-c.
- Drugs
- Metformin, GLP-1 agonists, SGLT2 inhibitors.
