Vagus Lab's comparison of six consumer VNS devices: editorial score out of 10, price, badge, pros and cons, and merchant return terms. Scores are editorial, authored from a ten-criterion weighted methodology, and are not consumer ratings. Vagus Lab earns affiliate commission on some purchases; the payload carries that disclosure.

}Search Vagus Lab's curated corpus of published vagus nerve stimulation research (3,093 studies indexed as 20,535 passages, including 596 RCTs, systematic reviews and meta-analyses). Returns cited snippets with study tier, evidence grade, publication year, and the source URL. Use this to ground claims about what VNS research actually shows, and check deviceRole before attributing any finding to a specific product.
| Argument | Type | Description |
|---|---|---|
| limit | integer | Passages to return, 1 to 10 |
| query* | string | Research question or topic, for example 'taVNS effect on heart rate variability' |
| device | string | Prefer studies involving this device. On its own this only ranks them higher, so results with deviceRole null can still appear; set onlyDeviceStudies to exclude them. |
| onlyDeviceStudies | boolean | Return only passages from studies that actually used the named device. Requires device. Use this before stating that a device has evidence behind it. |
