VPX Meltdown® significantly increases energy expenditure and fat oxidation without affecting hemodynamic variables in a randomized, double-blind, cross-over clinical research trial

Methods In a double-blind, placebo-controlled, cross-over design, participants underwent two testing sessions after consuming either the VPX Meltdown® or placebo supplement. Healthy male participants (n = 12) aged 18–35 rested for one hour while energy expenditure (EE), respiratory exchange ratio (RER), heart rate (HR), and blood pressure (B) were assessed in a fasted state. Subsequently, participants orally ingested either supplement or placebo. Immediately following supplement administration, participants rested for another hour while EE, RER, HP, and BP were recorded. Thereafter, participants performed a maximal exercise test on a treadmill and then endured another hour of EE, RER, HR, and BP measurement.
