Use of raspberry ketones has been proven to be effective when it comes to weight loss, but people are now wondering why it was not noticed before, and the answer is that the raspberries are usually eaten in small quantities, which is insufficient to provide you beneficial effects.
Raspberry ketone is a naturally occurring compound present in raspberries and other dark colored berries such as blueberries and cranberries. If you do not have extensive chemical knowledge the word ketone word means nothing to you. This compound is in fact phenolic substance that gives the familiar taste of raspberries. Since this fruit contains very little of this substance, supplements are the only way to take it in a larger, sufficient amount.
To experience weight loss benefits, Dr. Oz recommended at least the dose of 100mg per day. To get the same effects from the fruit, you’d have to eat 90 pounds of raspberries every day, which is impossible. Because of that, this compound is extracted from fruit by a variety of procedures and packed in a capsule form.
