Special Issue Information

Dear Colleagues,

The expanding and unsupervised use of dietary supplements is being increasingly reported worldwide. The increased focus/social pressure on body image, physical appearance and physical fitness is a major driver of the use of dietary supplements, not only among athletes but also in other sectors of the population. The rise in demand for dietary supplements is generally attributed to reasons including, but not limited to, enhancing performance, improving health, preventing nutritional deficiencies and illness, increasing muscle mass, decreasing body fat, boosting immunity, increasing alertness and mental activity, improving recovery, and reducing stress. The role of dietary supplements in appetite regulation and body weight management has also been explored, and varied effects on appetite, energy expenditure, and body weight were reported. Some supplements have been promoted for suppressing appetite and supporting weight loss, whereas others have been shown to stimulate appetite and regulate metabolic abnormalities that cause the inefficient utilization of nutrients in conditions such as cachexia. However, the exact benefits of dietary supplements are still not well established.

This Special Issue aims to communicate up-to-date evidence-based knowledge on the role of dietary supplements in appetite regulation and body weight management and the underlying mechanisms of action. All forms of manuscripts, including experimental papers, narrative reviews, systematic reviews, meta-analyses, and short communications, are welcome.

We look forward to receiving your submissions.

Dr. Dalia El Khoury

Synephrine has been used to promote weight loss; however, its safety and efficacy have not been fully established. The goals of our study were to give an overview of the safety and efficacy of p-synephrine, to systematically evaluate its efficacy regarding weight loss and to assess its safety, focusing on its cardiovascular side effects in a meta-analysis. PubMed, the Cochrane Library, Web of Science and Embase were searched for relevant studies. Only placebo-controlled, human clinical trials with synephrine intervention were included in the meta-analysis. The meta-analysis was reported according to the PRISMA guidelines using the PICOS format and taking into account the CONSORT recommendations. Altogether, 18 articles were included in the meta-analysis. Both systolic and diastolic blood pressure (DBP) increased significantly after prolonged use (6.37 mmHg, 95% CI: 1.02–11.72, p = 0.02 and 4.33 mmHg, 95% CI: 0.48–8.18, p = 0.03, respectively). The weight loss in the synephrine group was non-significant after prolonged treatment, and it did not influence body composition parameters. Based on the analyzed clinical studies, synephrine tends to raise blood pressure and heart rate, and there is no evidence that synephrine can facilitate weight loss. Further studies are needed to confirm evidence of its safety and efficacy. Full article

Dietary supplements are widely used among athletes, but many may be unaware of the potential for unintentional doping, especially considering that supplements can often be contaminated with prohibited substances. The reason behind the widespread use of dietary supplements among athletes is often cited as being for the purposes of enhancing health or performance. However, many athletes turn to unreliable sources of information, and often lack knowledge of dietary supplement regulations. The aim of this narrative review is to explore the current research surrounding the psychological constructs (such as norms, attitudes, and beliefs) related to dietary supplement use among athletes that may lead to inadvertent doping. This review also covers possible programme structures that may be effective at preventing inadvertent doping. Full article
