The #1 Raspberry Ketones brand on Amazon! Raspberry Ketone is a natural phenolic compound that is responsible for the heavenly aroma of red raspberries. Raspberry ketones helps increase fat breakdown and increase fat burning by a number of different mechanisms. It can lead to increased lipolysis, which helps breakdown fat, increased resting energy expenditure, which increases the rate in which calories are burned, and increased fat loss during dieting. The other main benefit is the fact that Raspberry Ketones are natural and not synthesized. To actually get the common dose of Raspberry Ketone, you would have to consume 90 pounds of raspberries.
