Our method
How we review a device
Every device page covers the same points, so you can compare devices on equal terms.
- Regulatory status: what a regulator has authorized, for which use, and what is sold only as a general wellness product.
- Evidence: the studies behind it, with their design (randomized, sham or placebo controlled), size and length.
- Results both ways: trials that found no benefit or mixed results are reported alongside positive ones.
- Funding: whether the maker ran or paid for the study.
- Safety and who it is for: who should talk to a clinician first.
Each device works differently, so each page explains its own mechanism. For background on light-based devices, read The Accidental Discovery of Redlight Therapy. For the energy story behind cell aging, see NAD+ and our longevity supplements.
Vanu Health does not sell these devices. Links to makers are for information. General information, not medical advice.
Questions
What does a device’s regulatory status mean?
It tells you what a regulator has authorized, and for which use. A general wellness device can be sold without a claim to treat any disease, so its status alone does not show that it works.
Does Vanu Health sell these devices?
No. These pages are independent education from the Vanu Health Research Team, with links to each maker’s official website.
Are these devices safe?
Each device page has a safety section, and precautions differ by device. Talk to a clinician before using any device if you have epilepsy, are pregnant, or have a condition the device is not designed for.
