The raspberry ketone used in the supplements marketed today is the same compound used in the food and cosmetics industry since the 1960’s. It is used as an additive to give certain products a fruity odor or flavor. Naturally extracted raspberry ketone is one of the most expensive additives in the market but its synthesized version is rather easy on the pocket and just as effective. The FDA has given it a GRAS or Generally Recognized as Safe status.
Several studies have shown that raspberry ketones have fat-burning properties. It is actually similar to Capsaicin, a compound found in hot peppers that increase metabolism. It is also similar to synephrine ( a form of the stimulant ephedrine)which is an alkaloid found in bitter orange extracts. Where the two are bitter and “hot”, raspberry on the other hand is sweet.
All three ingredients are used in fat-burning supplements but raspberry ketones works differently and none of the irritating effects. The mice studies done in 2005 shows that despite a high fat diet given them for 10 weeks, those that were given varying doses of raspberry ketone lost body weight and a decreased fat build up in their liver. Another mice study also shows that raspberry ketone increases the level of adiponectin in our body. Adiponectin is a protein responsible for regulating glucose levels and fatty acid breakdown. Apparently, as we gain weight, our adiponectin level decreases. So then it makes sense that if we increase the levels of this protein, we also increase our body’s ability to breakdown fats and regulate blood glucose levels.
Another way to increase adiponectin is to exercise, and lots of it. But then the majority of people who need to increase adiponectin levels are already overweight, which means exercise is not easy. Raspberry Ketone is the right supplement to help them along. To help them lose weight so working out will not be as grueling as it should be.
Acceptance of the raspberry ketone as a fat burning supplement is split in two. There are doctors who agree and even endorse the theory and the effectivity of raspberry ketone. They think that the study us enough and so far, raspberry ketone use has not produced any unpleasant side effects. The mice study has also shown that raspberry ketone has no adverse side effects.
On the other side, some doctors and health professionals believe that we should wait for human studies and the proof of its effectivity in humans and its possible negative side effects. The choice is yours, either to wait and gain weight for the meantime or try the raspberry ketone supplements now and see if it works on you like others who have successfully reached their weight goals.
