Assessment of Heavy Metals in Mexican Dietary Supplements Using Total X-Ray Fluorescence Spectrometry and Health Risk Evaluation.

ABSTRACT: This study used Total X-ray Fluorescence Spectrometry (TXRF) to analyze toxic heavy metals, specifically lead (Pb), arsenic (As), and chromium (Cr), in 45 dietary supplement samples consumed by the Mexican population. A health risk assessment was performed using the Target Hazard Quotient (THQ), Hazard Index (HI), and Cumulative Cancer Risk (CCR). The mean concentrations of Pb, Cr, and As were found to be 1.99 ± 0.13, 26.88 ± 0.23, and 2.39 ± 0.11 mg/kg, respectively. For Pb, 80% of dietary supplements showed low EDIs compared to the reference value of 1.08 × 10^-4 mg/Kg bw/day set by the FDA. For Cr, 100% of the analyzed products had EDIs below the limit of 0.3 mg/Kg bw/day established by EFSA. Additionally, some dietary supplements of animal origin had EDIs exceeding the refere
