Raspberry ketone for weight loss?— published: 01-17-2017
Some dietary supplements marketed for weight loss contain “raspberry ketone.” This ingredient is one of several naturally occurring chemicals found in red raspberries that contribute to their aroma; it also occurs in other fruits such as cranberries and blackberries. Raspberry ketone is used in some foods as a flavoring agent and in other products such as cosmetics. Because the amount of raspberry ketone found naturally is so low, it is produced synthetically in a laboratory for use in commercial products.
The limited number of studies done on cells, mice, rats, and other small animals indicate that raspberry ketone might improve fat metabolism. However, the same effect has yet to be established in humans, and currently there is insufficient scientific evidence that supplemental raspberry ketone is effective for weight loss.
