Of interest is the potential real world application of this study considering all of the participants Go6983 mw were habitual caffeine consumers with a moderate

daily intake of caffeine (<200 mg/day) and were still responsive to the active supplement treatment. This regular intake of moderate amounts of caffeine may explain much of the lack of observed hemodynamic and ECG effects in this investigation. Tolerance to caffeine can develop within four days of consuming 150 mg/day [26] and this built-up tolerance can negate or reduce the side effects often seen when a non-caffeine user ingests a caffeine-containing beverage/supplement including increases in SBP, DBP, and changes in HR [27]. In addition to a lack of negative physiological side effects, participants also did not report any negative mood states or other side-effects. When participants were given 280 mg of caffeine in the form of coffee, Smits and associates [28] observed an increase in BP and a decrease in HR, while there were no significant changes among the control group (decaffeinated coffee). These changes in HR ABT-737 cell line and BP were assumed to be linked to the caffeine content of the regular coffee. Considering the supplement used in the present study contained 340 mg of total caffeine, habitual moderate caffeine usage seems to be the contributing factor to no significant changes in HR, BP, and ECG

data, as well as the lack of reported side-effects. Conclusion In conclusion, when taken by moderate caffeine users that are physically active and healthy, the proprietary blend of this particular thermogenic supplement can increase REE and mood states related to alertness, focus, and energy without causing unsafe acute hemodynamic side-effects or increasing selleck chemicals perceived anxiety levels. Future research Arachidonate 15-lipoxygenase should evaluate the chronic combined effects of DBX with exercise. Acknowledgements We would like to thank all of our participants for volunteering
