A “revolutionary” product working without ephedra, Firelean EF instead focuses on the use of citrus aurantium, a popular ephedra alternative. They claim that along with green tea, it will suppress appetite and increase your metabolism to increase the amount of calories your body burns throughout the day. Usually, products promote citrus aurantium as the fat burner as well as an appetite suppressant, essentially a 2 in 1 deal. But the fact is, they don’t really use enough of any of the proven ingredients they do have, while using quite a bit of ingredients that aren’t proven to do anything for weight loss, such as guarana for example. They use an astounding 900mg as opposed to only 250mg of the proven green tea. They even call one ingredient a “bio thermo-potentiator” instead of actually naming the ingredient. They claim this product was developed by a doctor, but we would hope no doctor would be so misinformed or just greedy to create this.
