Ripped Fuel

Is Ripped Fuel safe to use?

From the Field

Does Ripped Fuel have any banned substances in it?

HPRC's Answer

Weight loss product Ripped Fuel

Ripped Fuel is marketed as a weight-loss product, specifically a fat burner, and is used by body builders to enhance performance and “boost energy.” The original formula contained ephedra, which has been banned by the Food and Drug Administration (FDA). Since the removal of ephedra, it has included other ingredients (not currently banned by the FDA) to mimic the effects of ephedra. One ingredient found in Ripped Fuel Ephedra Free—Metabolic Enhancer—is bitter orange fruit extract. Bitter orange contains synephrine, which is similar to ephedra in that it is a stimulant that increases heart rate and blood pressure. Manufacturers have substituted synephrine in products that previously contained ephedra. Marketed as “ephedra free,” they may contain synephrine from bitter orange, sometimes plus caffeine and/or caffeine-containing supplements. Products that contain synephrine very likely have the same risks as products that contained ephedra. The FDA has submitted recommendations to have bitter orange added to the ephedra ban. Use of bitter orange (synephrine) has been banned by the National Collegiate Athletic Association (NCAA).

Other Ripped Fuel products include Ripped Fuel 5X, Ripped Fuel Xtendr, and Ripped Fuel Extreme. These products contain many combinations of ingredients, some including several forms of caffeine. Caffeine is included on the FDA list as a substance “generally recognized as safe.” However, the FDA guidelines for cola beverages have established a maximum concentration for caffeine: 32.4 mg per 6 oz or 71 mg per 12 oz portion. Other than colas, the caffeine content of food and beverages is not regulated. It is important to read the label ingredients for caffeine content as well as other ingredients. A caffeine-containing supplement found in one Ripped Fuel product is guarana seed extract; according to the product label, this extract contains 22% caffeine. Green tea extract and cocoa seed extract, both of which are listed ingredients on their products, also contain caffeine. According to the company, the following is the caffeine content (listed in mg) found in the Ripped Fuel products:

  • Ripped Fuel Ephedra Free: 176 mg/serving (two capsules)
  • Ripped Fuel Xtendr: 101 mg/serving (two tablets)
  • Ripped Fuel 5X: 99 mg/serving (one tablet)
  • Ripped Fuel Extreme: 220 mg/serving (two capsules)
