Lucy Heat “unflavoured” oral nicotine pouches robustly activated hTRPV1, with nonivamide at ~675 microgram/pouch, indicating potent capsaicinoid “heat” despite “unflavoured” marketing.
- Why it matters: Flavor bans may push manufacturers to use alternative sensory additives, so it is important to verify whether “unflavoured” products still deliver characterizing heat effects.
- What they did: Online merchants were searched for “unflavored” ONP sold in U.S. jurisdictions with flavor restrictions; aqueous extracts from “heat,” “spicy,” and “unflavoured” products were tested in HEK293 cells expressing hTRPV1 using Ca2+ microfluorimetry, and capsaicinoids/sweeteners were measured by LC/MS.
- The result: Extracts from all identified “heat”/“spicy” ONP robustly activated TRPV1, and chemical profiling showed capsaicinoid mixtures (5–25 microgram/pouch) plus other flavors in some products, with sweeteners present in all tested ONP.
