Looking to lose that last bit of weight or thinking about a lifestyle change to shift the number on the scale? Thermogenic supplements (or fat burners) are one way to help reduce excess weight. Thermogenics work by enhancing thermogenesis, the process by which the body produces more heat and burns more calories. Capsicum, Green Tea and Caffeine are three natural ingredients that are known for their weight loss-inducing properties. Vitamin B6 is also essential for the metabolism of glycogen and protein, enhancing fat oxidation to burn calories.
