Continuous glucose monitoring
A small wearable sensor tracking real-world glucose patterns over one to two weeks, revealing responses a single blood draw cannot capture.
What it is & how it works
A small wearable sensor tracks interstitial glucose levels continuously over one to two weeks, revealing real-world glucose patterns and responses to specific meals and activity that a single fasting blood draw cannot capture.
How it's done
A sensor patch is applied to the arm or abdomen, typically worn for 10–14 days, syncing glucose data to a smartphone app. Data is then reviewed with a clinician or nutritionist to individualize dietary and activity recommendations.
Conditions it treats
Why Unfold Longevity
Used to individualize nutrition guidance based on a patient's own real-world glucose response rather than generic dietary advice, in keeping with Unfold Longevity's individualized-outcomes model.
Evidence & safety
Individualizes nutrition guidance based on real-world response; an increasingly used tool outside diabetes management specifically.

Insertion involves a brief pinch as the sensor's small filament is placed under the skin; most people find the sensor comfortable to wear for the following 10–14 days once it's in place.
Because it tracks interstitial glucose continuously rather than at a single moment, a CGM can reveal how your glucose responds to specific meals, activity, and sleep over one to two weeks — patterns a single fasting blood draw can't capture. Evidence for its benefit in people without diabetes is still emerging, and it's currently used mainly as a lifestyle-education tool rather than a diagnostic test.
