GAA has been used as a dietary supplement many years before its well-known complement creatine, yet it still remains far less described in terms of effectiveness and safety, with only two dozen studies evaluating GAA applicability in humans, some actually conducted in our lab. In a chapter of just-published book Dietary Supplementation in Sport and Exercise (Routledge, 2019) edited by Jay R. Hoffman, Dr Ostojic provides an update on GAA pharmacology, efficacy and safety in medicine, sport and exercise and an overview of possible advanced formulas that contain GAA.

Besides GAA, this excellent title covers a variety of supplements, including micro-nutrients and macronutrients, beta-alanine, creatine, caffeine and probiotics, as well as innovative ergogenic aids, perhaps a perfect resource for both undergraduate and graduate students, and all professionals working in the field of sport nutrition.
