“…Regarding performance supplements, caffeine and creatine monohydrate stood out as being widely used and researched in team sports, including handball [ 8 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ]. Caffeine is the most widely used psychoactive substance in the world, recognized by the International Olympic Committee for effectively improving performance in various sports disciplines [ 9 ].…”

“…Caffeine is the most widely used psychoactive substance in the world, recognized by the International Olympic Committee for effectively improving performance in various sports disciplines [ 9 ]. Numerous studies suggest an increase in performance following ingestion of 3–6 mg·kg −1 consumed ~60 min prior to exercise [ 9 , 30 , 31 , 32 ]. It is suggested that caffeine exerts its influence on the central nervous system by antagonizing adenosine receptors, resulting in increased neurotransmitter release, increased motor unit firing rates and pain suppression [ 32 ].…”

“…Protein intake contributes to the synthesis of muscle mass and the maintenance of bone health, as well as increased strength, improved post-exercise recovery, enhanced immune system response and reduced likelihood of musculoskeletal injury [ 30 , 47 , 48 ]. Although dietary protein intake may be sufficient [ 48 ], the amount of food needed to meet the requirements of a protein-rich diet must be considered.…”

“…The use of this type of questionnaires on supplement consumption by the entire technical-medical staff around the players can also provide information on aspects related to the performance and recovery of each player. In this way, teams can have protocols, based on scientific evidence, about which supplements are safe and influence the improvement of each player [ 30 ]. In turn, it has the potential to unveil risk practices associated with the use of SS in handball players, including suboptimal doses, doping substances and inadvisable SS combinations that may lead to interactions with other SS or medication, causing adverse effects.…”

(1) Background: Given the physiological characteristics of handball, players may require the use of certain sports supplements (SS). However, very few studies have investigated the consumption of SS in handball. The aims were to determine the number of handball players who consume SS, to analyze their SS consumption pattern according to gender and competitive level, and to assess whether the SS they consume are supported by scientific evidence, and to which group they belong according to the classification of the Australian Institute of Sport (AIS). (2) Methods: A descriptive-correlational study was carried out on the habitual consumption of SS in 360 federated Spanish players by using a self-administered and validated questionnaire. (3) Results: These showed 65.8% of the sample consumed SS. According to the total number of participants, the most consumed supplements were from Group A: sports drinks (30.8%) and whey protein (30.4%). When analyzing the data by gender, the men’s consumption was significantly higher for whey protein (p < 0.001), caffeine (p = 0.009), and creatine monohydrate (p < 0.001). When analyzed by competitive level, the provincial category players group showed a significantly lower consumption than the rest of the groups for protein bars (p = 0.038), whey protein (p = 0.005) and creatine monohydrate (p < 0.001), while the honor division group showed a significantly higher intake of creatine monohydrate than the remaining groups (p < 0.001). (4) Conclusions: The handball players showed a moderate consumption of SS, without using substances that were not supported by scientific evidence and opting in most cases for supplements belonging to group A from the AIS classification. Men tended to consume more SS, and SS consumption increased based on competitive level.
