Dexcom Stelo vs Mito Red MitoMOBILE 3
Two devices, the same questions: what does it actually measure, how good is the data, what does it cost to keep using, and who is it for.
Dexcom Stelo
The first over-the-counter continuous glucose monitor in the US. A 15-day skin-worn sensor that turns a black-box variable — your glucose response to food, stress and sleep — into a graph you can act on.
Full review →Mito Red MitoMOBILE 3
A mid-size photobiomodulation panel that delivers therapeutic red (660 nm) and near-infrared (850 nm) irradiance for skin, mitochondrial and recovery protocols at a fraction of clinic pricing.

| Price | Not sold in the UK — Abbott Lingo is the equivalent here, around £120/month | Around £500–750, plus import duty if shipped from the US |
| Subscription | None (device is single-use) | None |
| Form factor | Skin-worn sensor, upper arm, 15 days per sensor | Vertical LED panel, wall-mount or stand |
| Battery life | Sensor lifespan 15 days | Mains-powered |

|
| Data quality | MARD (mean absolute relative difference) in the ~10% range vs venous blood glucose — best-in-class for consumer CGM. Interstitial lag makes rapid spikes appear ~5 minutes late. | The device itself has no telemetry. Manufacturer irradiance claims are broadly consistent with third-party measurements; verify with a photometer if precision matters. |
| Ecosystem | Native Stelo app; data export to Apple Health and Google Health Connect. Third-party integrations via Dexcom API and platforms like Levels, Nutrisense and Signos. | No app or ecosystem — pair with a manual protocol log or a habit tracker. |
| Privacy | Glucose data stored in Dexcom cloud; can be exported as CSV. HIPAA-aligned handling. | n/a — device does not collect data. |
Dexcom Stelo
- Otc — no prescription needed for non-diabetics in the US
- 15-day wear, waterproof, minimally invasive
- Turns diet and exercise into an immediate feedback loop
- Best-in-class sensor accuracy in the CGM space
- Not intended for insulin-dependent diabetics (see G7 for that)
- 15-minute readings vs 1-minute on G7 — smoother, less real-time
- Interstitial fluid lags blood glucose by 5–10 minutes
- Metabolic-optimisation users identifying personal glycaemic responses
- Anyone with pre-diabetes or a family history of type 2 diabetes
- People chasing zone-2 fitness or GLP-1 protocol optimisation
- Type 1 diabetics needing dosing decisions from the device
- Users unwilling to wear a visible sensor on the arm
Mito Red MitoMOBILE 3
- Well-characterised wavelengths that match the strongest photobiomodulation literature
- High irradiance at short distances shortens session times
- Solid clinical-grade build vs low-end Amazon panels
- No dosimetry, timing or protocol built into the device
- Overdosing (too long, too close) can blunt hormesis
- Panel size limits full-body sessions vs bed-format devices
- Skin rejuvenation, wound healing, targeted joint pain
- Post-workout mitochondrial recovery protocols
- Winter mood support alongside a bright-light box
- Users with photosensitising medications
- Anyone unwilling to protect eyes and track dose
The lowest-friction way to turn glucose into an actionable metric. Non-diabetics should treat it as a 15–30 day learning tool, not a permanent wear.
A serious mid-size panel for anyone who wants clinical-grade red-light therapy at home without paying subscription clinic pricing.
