The promise of checking your blood sugar without pain, needles, or test strips sounds too good to be true. Laozik claims it can do exactly that by using just a fingertip, a laser, and some AI. But in a space where accuracy could mean life or death, does this device actually deliver what it promises, or is it another overhyped gadget cashing in on diabetic fears?
In this review, I’ll break down what Laozik is, how it supposedly works, what the science really says, red flags to watch for, and whether it’s worth trusting with your health.
Key Takeaways
- Laozik is marketed as a non-invasive, painless laser-based glucose monitor, using optical spectroscopy and AI in a finger clip to measure blood sugar, SpO₂, heart rate, etc. within 5–8 seconds, claiming “99.9% accuracy” and approvals like FDA, CE, ISO 13485, CE, TUV SÜD.
- There are zero independent clinical studies validating the device’s accuracy or reliability. All data stems from promotional websites with stock claims and anecdotal testimonials .
- Expert consensus is clear: no non-invasive glucose monitor has reliably reached medical-grade accuracy. Reddit threads call these devices “scams” with false FDA claims and misleading marketing .
- Marketing employs funnel tactics: countdown timers, free gifts, non-peer-reviewed “certifications,” and artificial urgency, all common among high-risk direct-to-consumer gimmicks.
What Is Laozik?
Launched through multiple domain funnels, Laozik devices are small finger-clip gadgets (approx. $30–$40) that claim to non-invasively measure blood glucose, heart rate, SpO₂, blood pressure, and sometimes uric acid, all via lasers and AI. They’re sold under names like “Advanced Laser Glucose Monitor” or “GlucoSense,” often backed by generic doctor endorsements and screenshots of certifications.
How It Claims to Work
- Laser/optical sensing shines through your fingertip.
- AI interprets absorbed light via hemoglobin or glucose molecules—based on unspecified algorithms.
- A silicone finger clip removes external light, supposedly improving accuracy.
- Results sync to an app via Bluetooth in seconds.
However, this tech has never been proven accurate enough for blood glucose measurement, not to diagnostic standards.
What Science Actually Says
- Non-invasive glucose monitoring remains an unsolved challenge since 1975; no commercially viable devices exist due to unreliable accuracy.
- Reddit users warn, “These are scammy and no such thing exists” or “fake FDA claims,” and stress that current CGMs rely on interstitial fluid sensors or finger pricks.
- Optical hardware like lasers and AI may read light absorption, but glucose levels can’t be accurately deduced from surface spectral data without rigorous calibration, which Laozik provides none of.
Red Flags To Consider
No Medical Validation
No peer-reviewed, independent trials or data demonstrating the device works, just marketing copy and testimonials.
Misleading Claims & Fake Certs
“FDA certified,” “clinically proven,” “German hospital tech”, these are repeated marketing terms not backed by verifiable records. Topical certifications don’t confirm medical use.
Expert & Public Skepticism
Reddit consensus: “No such accurate non-invasive device exists… Everything else is scam.”
Funnel & Scam-Like Marketing
Amazon-free, sold via gated funnels with countdown timers, referral codes, and gift giveaways, classic signs of questionable sales operations.
Does It Actually Work?
No, don’t rely on it.
- For reliable glucose data, finger-prick meters or CGMs like Dexcom and Libre are only clinically proven at-home options.
- Laozik’s “99.9% accuracy” claim is unsubstantiated and likely false.
- Users depend on actual blood readings; trusting this could lead to mismanagement of blood sugar and risked health.
Alternatives
- Finger-prick glucometer
- Continuous Glucose Monitors (CGMs)
- Early-stage non-invasive R&D
Conclusion
Laozik is a non-invasive glucose monitor with flashy claims but zero credible evidence. It promises breakthrough tech, non-invasive, accurate, smartphone syncing, but all signs point to marketing hype and pseudoscience. If monitoring glucose matters, stick to proven devices and disregard unverified gadgets like this.
