Ripped Fuel is a thermogenic dietary supplement produced by Twinlab, a subsidiary of Ideasphere. Thermogenic dietary supplements, more commonly known as weight-loss supplements, were classically made up of ephedrine, caffeine and aspirin, known as the ECA stack (ephedrine, caffeine and aspirin). However, in 2005 the Food and Drug Administration (FDA) banned all dietary supplements containing ephedrine. Since then, Twinlab has released several evolutions of the original Ripped Fuel. One such evolution is made up of a replacement for the ephedrine, plenty of caffeine and a blend of feel-good herbs, antioxidants and phytochemicals.

In the classic ECA stack, ephedrine stimulates the hormones responsible for increased metabolism and body temperature. The caffeine and aspirin extend this thermogenic effect by shunting the body's attempt to normalize metabolism and body temperature. Ephedrine also promotes satiety and curbs hunger, although the mechanisms for these effects are not known.
Ripped Fuel contains the E and C components of the classic ECA stack with the addition of several ingredients to help dieters stick to their plan. Ephedrine is replaced by bitter orange fruit extract that contains synephrine, a similar metabolism stimulating and appetite suppressing compound. Green tea and guarana seed extracts contribute the caffeine portion of this weight-loss stack. Caffeine prolongs the thermic effect of synephrine while expressing its own thermogenic qualities. Green tea is also a powerful antioxidant thought to help regulate blood glucose levels. L-phenylalanine, St. John's Wort extract, ginger root and cayenne fruit are mood enhancers--some with anti-inflammatory properties--thought to curb hunger and promote satiety. Cayenne fruit also aids in digestion and promotes metabolism. Ripped fuel does not contain aspirin in the form of willow bark, like other thermogenic dietary supplements. However, it does contain other ingredients with similar inhibiting effects that may produce the same result.
Thermogenic dietary supplements are weight-loss aids designed for healthy adults seeking to complement or enhance an effective diet and exercise program. There is a risk of developing caffeine addiction from dietary supplements. This risk can be minimized by cycling on and off caffeinated supplements while maintaining a healthy lifestyle. Because Ripped Fuel doesn't contain aspirin, it may be a safe alternative for those with aspirin restrictions.
The FDA regulates thermogenic dietary supplements as foods, not drugs. This means the safety and effectiveness of Ripped Fuel and similar products is not tested and proven before becoming commercially available. Ask your physician and nutritionist if a thermogenic dietary supplement such as Ripped Fuel is right for you. Always purchase dietary supplements from trusted brands.
