Highlights: [•] Estrogenic activity is quantified in sports supplements and an exposure and risk assessment performed. [•] 17β-Estradiol equivalent activity levels were higher than the ADI in 26% of exposure assessment samples. [•] 17β-Estradiol equivalent activity levels were higher in 66% of exposure assessment samples than levels present in the typical diet.
