Hydroxycut is a line of dietary supplements consisting mainly of lady's mantle extract, wild olive extract, komijn extract and wild mint extract, according to WebMD. Some Hydroxycut products contain caffeine and green coffee bean extract.
Hydroxycut purportedly burns fat, boosts a person's metabolism and reduces appetite, explains HowStuffWorks. The ingredients responsible for these effects are caffeine and ephedra, a Chinese herb claimed to improve thermogenesis, which is the body's way of generating heat by increasing metabolism above the normal rate. HowStuffWorks notes that there are no independent studies that prove the efficacy of Hydroxycut. The products rely on large amounts of caffeine to increase the body's blood pressure and body temperature. This supposedly burns more calories within eight weeks. Extract from garcinia cambogia, a fruit native to India, was claimed to inhibit an enzyme that transforms extra carbohydrates into fat.
Hydroxycut manufacturer Iovate Health Sciences Inc. recalled 14 products from its Hydroxycut line after the Food and Drug Administration banned the weight loss supplements in 2009, according to the official FDA website. The FDA warns consumers to avoid using Hydroxycut products as these supplements have been associated with serious health problems, such as jaundice, elevated liver enzymes and liver damage. The FDA received a report of one death due to liver failure.
