One factor which is probably unknown and could contribute towards the unexpected results of this study is the aluminium content of energy drinks. We measured the aluminium content of a number of energy drinks widely available in the United Kingdom and found that the concentrations ranged from 75 to 1902 µg/L). For example, we measured the aluminium content ( µg/L), mean and SD are given for n=5) of the following branded products; Rockstar – 74.5 (6.5); Monster – 96.3 (29.5); Tesco Ble Spark – 103.3 (7.1); KX Jason Plato – 116.6 (11.4); Relentless – 139.3 (13.3); Boost – 157.2 (5.9); KX – 202.4 (3.2); Red Bull – 272.2 (27.5); Black – 952.0 (41.9); Morrison’s Source – 1131.0 (42.5) and EQ8 – 1902.0 (28.8).
There is a significant body of research documenting how exposure to aluminium affects heart and vascular function (see for example, Schmidt et al. (2016) Toxicol. Appl. Pharmacol. 313, 109-118). The aluminium content of many energy drinks is several fold higher than is recommended in drinking water (50.0 µg/L)) and regular consumption of energy drinks will inevitably contribute towards the human body burden of aluminium.(http://pubs.rsc.org/en/content/articlelanding/2013/em/c3em00374d#!divAbstract)Competing Interests: None declared.
