This site's own FAQ addresses this directly: no, Quiet Nerves is a dietary supplement, not a medication, and is not intended to diagnose, treat, cure, or prevent neuropathy or any other neurological condition.
General wellness support for daily nerve comfort and calm — not a claim to treat, diagnose, or replace medical care for neuropathy or any diagnosed neurological condition.
This site is direct that neuropathy is often tied to diabetes or other serious underlying conditions — this honesty about that limit is worth taking seriously before you buy.
