Objective: The presence of toxic metals in foods poses a significant risk to human health. Even low-level exposure to these metals can cause various health problems over a long period of time. In this study, we investigated the levels of toxic metals (Li, Al, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Sr, Cd, Sb, Ba, Pb and Bi) in 34 food supplement samples purchased from pharmacies in Edirne. Material and Method: The samples were digested using HNO3 in a microwave system and the metal content was analyzed using ICP-MS. Result and Discussion: Our results showed that none of the food supplements exceeded Turkish authority limits. Only Cd levels of two food supplements (0.431 μg/g and 0.316 μg/g) exceeded WHO guideline limits. We discussed the potential health effects of these metals and their compounds. Our findings suggest the need for increased regulation and monitoring of food supplements to ensure their safety and quality.
