Raspberry Ketones Raspberry Ketone Benefits Raspberry ketones are major aromatic compounds in red raspberries and are responsible for the fruit's characteristic aroma. Ketones are present in all berries such as blackberries, cranberries, and other fruits, and have attracted a lot of attention for their potential ability to aid weight loss. Interestingly, the structure of raspberry ketones is quite similar to that of capsaicin (found in hot peppers), ephedrine (a stimulant), and synephrine (an alkaloid, occurring naturally in some plants and animals), three compounds that are known to possess anti-obesity properties and alter lipid metabolism inside the body. https://www.nationalnutrition.ca/fruit-supplements/raspberry-ketones.html #RaspberryKetones
