Copy That Sells Without Crossing the Line
Supplement copywriting is the hardest kind of DTC copy: the market rewards specific, benefit-driven claims, but the FDA (US) and EU regulations punish disease claims. AI tools are excellent at generating the volume - product descriptions, email sequences, ad variations - but the compliance filter is still a human job. The workflow that works: AI drafts, compliance checks, marketer approves.

FAQ
Can AI write compliant supplement claims? It can draft within guardrails, but you must verify: no disease claims, substantiated structure-function claims only. Have a regulatory reviewer check everything before publishing.
Which is best for email sequences? Jasper - its workflow templates are built for email flows, and brand voice training keeps sequences consistent.
Do these tools know supplement regulations? They know the general rules and can be prompted with your compliance guidelines, but they are not regulatory software - the human check is non-negotiable.
