Turn Up the Heat & Boost Your Burn

Thermogenesis is the body’s process of burning calories to produce heat. This raises your metabolic rate and prompts your body to burn stored fat for energy. Thermogenesis happens naturally when you exercise, and is one of the reasons that exercise promotes weight loss. But the more you work out and lose weight, the more efficient your body gets at converting calories into energy, until eventually, you reach a weight loss plateau.

NatureWise ThermoSpark™ contains clinically tested plant extracts, herbs, and nutrients designed to turn up your metabolic rate and help boost your burn. It includes natural thermogenic ingredients like Green Tea, Guarana, Yerba Mate, Rhodiola, Cayenne, and Kola, plus Advantra Z, a patented bitter orange extract that’s proven to raise metabolism and reduce body fat more than diet and exercise alone.*
