^In a randomized, double-blind, placebo-controlled study of 112 healthy volunteers, subjects taking the GNC vitamin and mineral blend in this product for six weeks experienced statistically significant improvements in markers of B vitamins and antioxidant status, as well as improvements in SF-36 Vitality and Mental health scores compared to those taking a placebo. In a randomized, double blind, placebo controlled study, 50 healthy untrained male volunteers were given Energy Enhancer N.O. or a placebo. Each subject exercised on a cycle ergometer prior to receiving the supplement or placebo and again after the treatment period was finished. Those subjects supplemented with Energy Enhancer N.O. had a 20% increase in PWCFT (physical working capacity at the fatigue threshold) after four weeks of supplementation relative to the placebo group. In a double blind, randomized, placebo controlled cross-over study, 25 subjects exercised on a treadmill on two occasions. On one occasion the subjects took Thermo Igniter 12x and on the second occasion, they took a placebo. When the subjects took Thermo Igniter 12x, they burned three times more calories before, 3% more calories during and 12 times more calories for up to one hour after exercise compared to when they took the placebo.
