Special Issue Information

Dear Colleagues

The consumption of food supplements, also known as dietary supplements, has been rising in recent years, driven by consumers’ increasing interest in health and wellness, among other factors. In parallel to this growth, concerns regarding food supplement composition, adulteration, and their health benefits and potential side effects have also become increasingly prominent. Among those, the most common concern is regarding adulterations, i.e., the insufficient amount of functional ingredients and the presence of contaminants such as pesticides, mycotoxins, and heavy metals. Adulterations mainly comprise the botanical adulteration of plant food supplements and the illegal addition of drugs to boost the effect of the product.

In addition, there is still a lack of information on consumption and consumers’ awareness regarding these products, as well as on several other aspects such as their nutritional properties, bioavailability, potential health benefits, and possible side effects.

This Special Issue aims to address these critical aspects by inviting original research articles, reviews, and perspectives that contribute to our understanding of food supplements and their impact on human health.

In recent years, the consumption of dietary supplements has grown worldwide, particularly in developed regions. However, this growing market has also become a prime target for adulteration practices, with some manufacturers illegally adding pharmaceuticals into plant-based food supplements (PFS) to enhance their effects. While extensive research has focused on detecting adulterant drugs in PFS tailored for improving sexual performance, weight loss, and muscle building, less attention has been given to supplements intended for mood enhancement, sleep aid, and cognitive function (nootropics). Nonetheless, recent reports indicate an increasing level of adulteration within this group of PFS. Therefore, this review aims at providing a comprehensive overview on the adulteration of PFS tailored for brain health, with a focus on the analytical techniques utilized for detection while also presenting data on consumption patterns and the prevalence of reported adulterants. Considering that the detection of such fraudulent practices primarily relies on chromatographic techniques coupled with mass spectrometry (MS), the developments in this field comprising either targeted or untargeted analysis of pharmaceutical adulterants are discussed.
