Human exposure assessment of fluoride from tea (Camellia sinensis L.): A UK based issue?

► Fluoride concentrations were determined in UK tea infusions and products. ► UK economy tea contained elevated fluoride, comparable to Chinese brick tea. ► Fluoride concentration significantly varies depending upon the type of tea. ► We report a risk of high exposure to fluoride if consuming 1L/day of Economy tea. ► Tea consumption alone can exceed the dietary reference intake of fluoride.
