Kafein dünya genelinde en yaygın olarak kullanılan besin maddeleri ve besin takviyelerinden biridir. Kafein tüketiminin büyük oranı kahve yoluyla olmakla birlikte birçok başka gıda, ilaç ve içecekte de kafein bulunmaktadır. Kafein son dönemde kullanımı yaygınlaşan enerji içeceklerinin de etken maddesi olarak işlev görmekte ve fizyolojik etkileriyle psikoaktif bir ajan olarak da kullanılmaktadır. Kafeinin faydaları ve riskleri ile ilgili birçok teori ortaya atılmakla birlikte, sağlıklı yetişkinler için günlük 400 mg’a kadar (75 kg. ağırlığında bir birey için yaklaşık 5.5 mg/kg) olan dozların güvenli olduğu ve herhangi bir sağlık riskine yol açmadığı bildirilmiştir. Kafeinin ergojenik bir yardımcı olarak kullanımı ile ilgili pratik ve uygulamaya dönük bilgilendirme antrenörler ve sporcuların performanslarını destekleme açısından önemlidir, bu derleme bu konuda detaylı bilgiler vermek üzere hazırlanmıştır

Caffeine is one of the most widely used nutritional supplements and nutrients. While a substantial part of caffeine consumption occurred through coffee, some other foods, pills and drinks contain caffeine as well. Caffeine also functions as the active ingredient of the recently popularized energy drinks and acts as psychoactive agent with its physiological effects. Though there are different theories that proposed about the benefits and risks of caffeine, it was reported that caffeine doses up to 400 mg a day for adults can be deemed as safe and do not result in any health risk. Practical and application-oriented briefing related to caffeine usage as an ergogenic supplement is important in order to support the performance of athletes and trainers. This review was prepared to give detailed information on this topic
