Razberi-K, also known as 4-(4-hydroxyphenyl) butan-2-one, is a ketone unique to red raspberry. Raspberries contain many bioactive constituents beneficial for health. One particular constituent, 4-(4-hydroxyphenyl) butan-2-one appears to have the potential to decrease body fat.

A recent study in Sarasota, Florida of this year adds to existing clinical research in which raspberry ketone has been shown to have anti-obesity effects by altering lipid metabolism, specifically by increasing norepinephrine-induced lipolysis, an effect which may enhance thermogenesis and oxidation of body fat.

The chemical structure of raspberry ketone is similar to that of capsaicin and synephrine. Both of which are well documented for their ability to produce thermogenesis through the release of norepinephrine. However, there are health risks with these two ingredients – synephrine has been shown to have dangerous cardiovascular side effects, while capsaicin has been shown to cause gastrointestinal distress in many users. There are no documented side effects related to raspberry ketone consumption.

This revolutionary ingredient is part of the Beyond Ripped Complex™ found exclusively in SUB•Q.
