US supplements is a category where Meta and TikTok punish small compliance mistakes, and the brands compounding are the ones who invested in creator-driven content, granular subscription cohort analysis, and a defensible Amazon strategy. Most supplement brands live with blended cac in the $35-$100 range, and the marketing program either respects that math or burns it.
FDA structure/function claim rules limit copy in ways that disable most performance ad angles. That is the constraint every supplement brands operator hits in the first 90 days of growth.
Meta ad disapprovals on supplement creative reach 25-40%, copy and creative compliance is a daily job. The shops that compound are the ones who solve this operationally before they solve it through advertising, but most operators try the reverse and pay tuition for 18 months.
Subscription churn at 35-50% means month-over-month subscriber growth requires aggressive top-of-funnel. Inparlor's engagement for supplement brands reflects that, we run the program against the unit economics, not the vertical brand.
