Contaminants in Dietary Supplements: Toxicity, Doping Risk, and Current Regulation
Int J Sport Nutr Exerc Metab. 2024 Apr 23:1-10. doi: 10.1123/ijsnem.2023-0263. Online ahead of print.ABSTRACTAthletes, both amateur and professional, often resort to the consumption of nutritional supplements without professional supervision and without being aware of the risks they may entail. We conducted an exhaustive literature search to determine the most common substances found as contaminants in dietary supplements. For each substance, we analyzed its mechanism of action, clinical indication, health risk, and putative use as doping agent. In addition, we evaluated the current regulation of these supplements. Contami...

Effect of Menstrual Cycle Phase and Hormonal Contraceptives on Resting Metabolic Rate and Body Composition
Int J Sport Nutr Exerc Metab. 2024 Apr 23:1-11. doi: 10.1123/ijsnem.2023-0193. Online ahead of print.ABSTRACTThe cyclical changes in sex hormones across the menstrual cycle (MC) are associated with various biological changes that may alter resting metabolic rate (RMR) and body composition estimates. Hormonal contraceptive (HC) use must also be considered given their impact on endogenous sex hormone concentrations and synchronous exogenous profiles. The purpose of this study was to determine if RMR and dual-energy X-ray absorptiometry body composition estimates change across the MC and differ compared with HC users. This wa...
