Clinical Devices vs Wellness Gadgets
How US regulators separate medical devices from low-risk wellness products, what FDA's general wellness policy does and does not mean, and how to read a device's claims.

What FDA's general wellness policy says
FDA issued a guidance document called "General Wellness: Policy for Low Risk Devices". The version read for this page is dated January 2026. It describes the agency's compliance approach and is a set of nonbinding recommendations. [2]Under the policy, a general wellness product has two features: it is intended only for general wellness use, and it presents a low risk to users. [2] Wellness claims the guidance lists include weight management, physical fitness, relaxation or stress management, mental acuity and sleep management. [2]
Two points that are easy to miss:
- Being covered by the policy "does not establish" that a product has been shown to be safe or effective for its intended use. [2]
- The policy is about whether FDA intends to examine a product. It is not a seal of approval.
Where the line is drawn
The guidance says a product is not a general wellness product if its labeling, advertising, screen or function includes things such as references to specific diseases or diagnostic thresholds, alerts that tell a person to take clinical action, or claims of clinical equivalence or "medical or clinical grade". [2]For wearables that estimate things like blood pressure, oxygen saturation, blood glucose or heart rate variability with light sensors, the January 2026 guidance describes conditions under which FDA may treat the output as general wellness. These include being non-invasive, not intended to diagnose or treat disease, not meant to replace a cleared device, and not prompting clinical action. [2] It also says that blood pressure monitors, glucose meters and continuous glucose monitors, and electrocardiogram recording and analysis devices are examples of products that are not general wellness. [2]
Why blurred lines matter
Researchers have pointed out that consumer and medical neurotechnology can make similar claims, that consumer devices may be repurposed for medical uses, and that this raises safety questions. [6] Careful wording matters: a "wellness" label does not tell you whether the sensor is accurate, and accurate measurement does not prove that using the device improves health.A quick check before trusting a claim
| Question | Why it matters |
|---|---|
| Which exact model and function is described? | Clearance applies to named functions. |
| Does the maker name a disease? | That usually points to medical-device rules. |
| Is there an independent validation study of this model? | Specifications from the maker are not evidence of accuracy. |
| Does the claim go beyond the stated intended use? | FDA expects labeling to be consistent with the intended use. [2] |

Does "FDA general wellness" mean a device is FDA approved?
No. The policy describes products FDA does not intend to examine as devices, and it does not establish that a product is safe or effective. [2]
Can a wellness gadget replace a medical device?
Under the guidance, products that claim to substitute for a cleared or approved device, or claim "medical or clinical grade", are not general wellness products. [2]
Is "cleared" the same as "approved"?
No. Clearance (510(k)) rests on equivalence to an existing device. Approval (PMA) requires clinical evidence of safety and effectiveness. [3]
Does a supplement need FDA approval before sale?
FDA says it does not approve dietary supplements or their labeling, though some claim types need premarket review. [5]
Do these rules apply outside the United States?
Not necessarily. This page describes the US only; other regulators have their own rules, which were not read for this page.

Higher-risk technology stays out
How a device becomes "cleared" or "approved"
One example of how this works in practice: FDA's 2016 proposed order on cranial electrotherapy stimulators described them as prescription devices for psychiatric conditions, proposed a lower-risk class for devices intended for insomnia or anxiety, and proposed that those intended for depression need premarket approval. [4] That was a proposal; the final order was not read for this page, so the current classification is not verified here.
Supplements are a separate system. FDA does not approve dietary supplements, and a product sold as a supplement but marketed to treat or cure a specific disease meets the definition of a drug. [5]
