Dexcom G7 Continuous Glucose Monitor
The Dexcom G7 is the most accurate wearable for real-time metabolic testing. It moves beyond proxy metrics (like heart rate) to measure actual blood glucose levels, providing immediate feedback on nutrition and metabolic health.
Quality & Materials
Medical-grade wearable with a glucose-oxidase based electrochemical sensor. Features a much smaller footprint than the G6 and a fully disposable all-in-one applicator.
Evidence & Testing
Brand Transparency
FDA-regulated medical device with full public disclosure of clinical performance data and manufacturing standards.
Value Assessment
Expensive without insurance, but for users tracking metabolic health or pre-diabetes, the actionable data is far more valuable than standard fitness metrics.
Why Not Alternatives?
Superior accuracy (lower MARD score) compared to the Abbott FreeStyle Libre 3. It features a faster warm-up time and a more integrated app experience for data analysis.

Omron
3 Series BP7150
Only device on US Blood Pressure Validated Device Listing. 79% of upper-arm monitors sold online are NOT validated for accuracy.
Oura
Ring Gen 3
99.9% accuracy for resting heart rate. Best sleep tracking among wearables. Ring form factor is more comfortable than wrist bands for sleep.
Labcorp OnDemand
Men's Health Test
Labcorp is the gold standard for clinical accuracy because it utilizes venous blood draws at professional centers rather than finger-prick samples, which are prone to hemolysis and contamination. This test provides a comprehensive metabolic panel, lipid panel, and testosterone check with hospital-grade precision.
Thorne
Vitamin D Test
Thorne is a leader in clinical-grade diagnostics, offering a dried blood spot test that has been validated against traditional venous draws. Their reporting is exceptionally detailed, providing actionable insights beyond just a numerical value.
