“…High percentage of athletes consuming more than four supplements (14.7%), which was found in this study, can be compared with 15.1% reported by Nabuco et al [12], raising the awareness about possible health implications among youth. Dascombe et al [8] found that kayakers and swimmers use considerably higher number of supplements compared to other investigated sports, which is in agreement with this study exploring the possibility that athletes in individual sports rely more on supplementation than athletes in team sports.…”

“…Furthermore, similar prevalence can be observed in 87.5% of Australian athletes [8], 77.0% of Singaporean athletes [13], and 71.2% of USA adolescents [20], while more than half of the British athletes (62.0%) and 45.0% of Iranian athletes [6] take some type of a sports supplement [21]. On the contrary, Nabuco et al [12] reported that only 47.3% of Brazilian athletes use sport supplements. Scofield and Unruh [22] reported that only 22.3% of young USA athletes consume supplements.…”

“…The use of dietary supplements is also a risk factor for illicit substance use and may cause so-called inadvertent doping due to the contamination of their ingredients [11]. Another aspect worth considering is their effectiveness which is controversial [11, 12].…”

“…There are only a few studies published each year targeting the dietary supplementation in adolescents leading to insufficient resources and subsequent misjudgment of emerging trends in this field. Considering the participation of young athletes in the major sports events, it is important to know the patterns of sports supplements use among them in order to develop education programs towards avoiding unnecessary and indiscriminate supplements use [12].…”

Background The aim of this international study was to investigate the prevalence of the use of sports supplements among young athletes, as well as their knowledge and attitudes towards sports supplementation. Methods Organized survey study testing the level of knowledge, attitudes, beliefs and practices concerning the use of sports supplements was administered to 348 athletes, 15–18 year olds from 4 countries competing in 18 sports at the international level. Results The prevalence rate of the intake of sports supplements was 82.2%, with the protein supplements being predominant (54.5%). Coaches were identified as the primary source of information regarding supplementation (41.4%). The enhancement of athletic performance (35.4%) was the major motivation for the supplements intake. The majority of athletes (72.1%) were aware of associated health risks. The young athletes possess varying levels of knowledge regarding their own supplementation. The obtained data about the level of knowledge were statistically analyzed using the correspondence analysis. Less than 40% of athletes had the knowledge about the proper and intended use of protein, creatine, amino acids, beta alanine and glutamine, while they had greater understanding about vitamins and minerals, sports drinks and caffeine. The athletes in developed countries had greater access and utilization of professional resources such as dieticians. Young athletes are still unfamiliar with WADA regulations (55.5%), and the misuse of sports supplements represents an ethical dilemma for some. Conclusion These findings indicate the necessity of a comprehensive education of all team members about sports supplements and careful supervision of the athletic development of young athletes.

Purpose This cross-sectional study aimed to provide estimates of dietary supplements (DS) use and to examine the relationship between sports dietary supplements (SDS) use and sociodemographic and lifestyle characteristic, body mass index and total daily physical activity (PA) in the adult population of Brasília, Brazil. Methods DS use was collected from 506 adults via a Food Frequency Questionnaire. DS were divided into multivitamin-minerals, electrolyte drinks, energy, protein, partial meal replacements, creatine, caffeine, and others. Electrolyte drinks, energy, and protein supplements were considered as SDS. PA was estimated from a 24-h PA recall, and total MET (metabolic equivalents)/day and MET-h/day were calculated. Participants were categorized as physically inactive or active according to MET-h/day. Results DS were used by 68% of adults; multivitamin-minerals (38%) and protein supplements (29%) were the most commonly used products. SDS use was associated with the highest socioeconomic level, younger age, and male gender, but not with PA. Also, most SDS users were physically inactive. Conclusion These findings indicate that SDS may be used unnecessarily by adults in Brasília. Specific recommendations and control procedures for the use of SDS are warranted.
