What is Thermo Fusion and How Does It Work? Thermo Fusion is based on the science of Thermogenesis, the process of utilizing fat for heat and energy. It’s formula activates Brown Adipose Tissue (B.A.T), an organ that specializes in turning excess fat into heat energy... burning more calories. Many thermogenic products incorporate Ephedrine, which has been known to accelerate the heart rate or increase blood pressure, but fail to address the support of adrenal, cardiac and vascular issues. Thermo Fusion attacked this issue by formulating a proprietary blend of herbs, nutrients and supportive ingredients which can reduce the negative side effects encountered be other thermogenic products.
