No. Insomnia is a named sleep disorder, so treating it is a drug claim; a dietary supplement may say it “supports restful sleep” or “helps you fall asleep faster”.
Named sleep disorder.
We file this under named condition and rate it critical. It is enforced by FDA, FTC, Amazon, Meta, which matters because a single phrase can fail in more than one place at once: a listing suppression, an ad-account review and a warning letter are three different consequences of the same sentence.
This is the rewrite an audit ships for this phrase, in the words we would hand you.
'Supports restful sleep' / 'helps you fall asleep faster'
Sleep is a normal function.
Acceptable if supported by ingredient evidence.
Every structure/function claim on this page still needs the FDA disclaimer wherever it appears. That requirement has its own ruling.
