Naringin is a flavonoid compound found in grapefruit. Naringin gives grapefruit its characteristic bitter flavor. It is thought that naringin enhances our perception of taste by stimulating the taste buds. Studies have shown that naringin interferes with enzymatic activity in the intestines, and thus the break down of certain drugs. A number of drugs that are known to be affected by the naringin in grapefruit include calcium channel blockers, estrogen, sedatives, medications for high blood pressure, allergies, and cholesterol-lowering drugs. The interference cna lead to too much of these drugs in the body.
However, naringin has other interesting properties. It is on the list of ingredients in many fat burners. Naringin is thought to help extend effects and levels of caffeine. Caffeine exhibits thermogenic, or fat burning, properties. Naringin has demonstrated cholesterol lowering abilities as well as aldose reductase inhibitor abilities. It is also being studied for anti-cancer agents although no conclusions have been made.
