PhenoAge Gap: Am I Normal?
Your phenotypic age minus your calendar age: negative means your body is younger. Get it from the Phenotypic Age Calculator.
What is a good PhenoAge gap?+
The gap is your phenotypic (blood-based biological) age minus your chronological age. Negative is good: it means your physiology looks younger than your birthday. A gap of about −5 years or lower is excellent; positive values mean your body is aging faster than the calendar and is a prompt to act on the modifiable markers (glucose, inflammation, metabolic health).
How do I get my PhenoAge gap?+
Use the Phenotypic Age Calculator (linked below), which turns nine standard blood markers into your phenotypic age via the Levine 2018 algorithm. Subtract your calendar age from that (or just read the "Δ years" the calculator shows) and submit it here to see where you sit versus the community.
Is the community comparison clinical?+
No. It is a peer comparison among health-focused readers who tend to skew younger-than-calendar, so the crowd median is not a clinical norm. The value of PhenoAge is the trend in your own gap over time, not your rank against others.
How do I improve my PhenoAge gap?+
The glucose and hs-CRP (inflammation) inputs usually move it the most: improving insulin sensitivity, losing visceral fat, regular exercise, and better sleep lower both. Re-run the same blood panel every 3–6 months and watch the gap shrink.
