MHP TakeOff Hi-Energy Fat Burner is a supplement that claims to help you lose weight by increasing energy levels and boosting metabolism. It claims that its formula maximizes thermogenic fat burning, improves concentration and physical performance, and dramatically increases energy.

The principal ingredients are guarana seed extract and green tea leaf extract, two substitutes for the now banned amphetamine-like compound Ephedrine. Guarana contains a form of caffeine called guaranine that is 2.5 times stronger than the caffeine found in coffee and soft drinks. These ingredients may work like ephedrine and speed up calorie burning slightly.

TakeOff also contains the amino acid tyrosine, converts to thyroid hormone and to adrenalin, as well as a variety of herbs commonly found in Chinese medicine including ginseng, licorice, astragalus, schizandra berry, and ginko biloba.

There is no research showing that TakeOff leads to long-term weight loss, or that it is safe. Like most supplements, it has not been evaluated by the FDA for either effectiveness or safety.
