Ripped Fuel® is a dietary supplement that promises fat burning effects, 'ripped' abs, and weight loss. Ripped Fuel Ephedra Free® and Ripped Fuel Extreme® includes nutrients derived from herbs and botanicals that may help promote weight loss and enhance thermogenesis (calorie expenditure). Ripped Fuel Ephedra Free® contains bitter orange fruit extract (synephrine), guarana, phenylalanine, and a 'fat loss blend' of coleus forskolii, green tea, citrus bioflavonoids, ginger root, and cayenne. Ripped Fuel Extreme® contains calcium, chromium, cocoa, green tea leaf, caffeine, l-carnitine, cayenne and a proprietary herbal extract of flavonoids, skullcap root, and black catechu bark.
The manufacturer, Twin Labs, has not conducted clinical studies of Ripped Fuel® supplements. However, research suggests that synephrine and caffeine found in guarana and green tea may work synergistically to increase thermogenic effects and promote weight loss. Coleus forskolii and flavonoids have antihistamine properties similar to synephrine. In addition, carnitine has been shown to improve the utilization of fat.
Ripped Fuel's® ingredients don't necessarily target the abdominal muscles to create lean muscle mass. Ripped Fuel's® claim to be the only product that guarantees 'ripped abs' is accompanied by a disclaimer. "These statements have not been evaluated by the Food and Drug Administration," states the disclaimer. "This is not intended to diagnose, treat, cure or prevent any disease."
Ripped Fuel® recommends consulting a health care practitioner prior to use. Ripped Fuel® should not be used by women who are pregnant or nursing, by individuals who have a chronic disease of the gastrointestinal tract, or by those who eliminate caffeine from their diet.
