This site cites a specific NIH/NINDS overview page on peripheral neuropathy among its six research sources — worth understanding exactly what that source covers.
The National Institute of Neurological Disorders and Stroke (NINDS), part of the NIH, publishes this general overview of peripheral neuropathy as a medical condition — a government health resource distinct from the ingredient-specific PMC and NIH-ODS citations also listed.
This source describes the medical condition itself, not this formula's effect on it — worth reading it as background on what peripheral neuropathy is, alongside this site's own direct statement that Quiet Nerves is not a treatment for neuropathy.
