Dexcom G7
The Dexcom G7 is the gold standard for ecosystem integration, allowing users to see their glucose data on Apple Watch, Garmin, and various longevity platforms simultaneously. It features a 30-minute warm-up time, the fastest in the industry.
Ingredients & Purity
Features a redesigned sensor wire and an improved adhesive patch that includes an integrated overpatch for better retention during exercise and swimming.
Scientific Evidence
Supported by extensive clinical data showing high reliability across various age groups and activity levels, with a MARD of 8.2%.
Brand Transparency
Dexcom provides the most robust API for third-party developers, meaning your data is truly yours to use in longevity-tracking apps like Nutrisense or Levels.
Value Assessment
While the most expensive option (often $170+ per month without insurance), the value lies in the 'Direct to Watch' feature and the superior software ecosystem.
Why Not Alternatives?
The G7 outperforms the Medtronic Guardian by eliminating the need for fingerstick calibrations. It is superior to the older G6 by integrating the transmitter and sensor into a single, smaller disposable unit.
