Raspberry ketone is a weight loss supplement that has become quite popular lately. The active ingredient in the product is the same which is extracted from raspberries and is used in cosmetics as well as in food products such as soft drinks and ice cream.The ketones refer to the natural chemicals which give raspberries their aroma and they are used in foods and cosmetics because of this fragrance and as a flavorant.
What Are Raspberry Ketones?
Apart from raspberries, the same chemicals are also found in fruits like cranberries, blackberries, and kiwis. Raspberry ketone became popular as a fat burning supplement since their introduction by Dr. Oz in his show back at 2012. However, it may be instructive to know that the ketones used in the supplement are not naturally extracted from raspberries or any of those other fruits mentioned above.
This is for the simple reason that extracting the chemicals naturally will be overwhelmingly expensive since it is known that a single dosage of raspberry ketone can only be extracted from 41 kg of raspberries! Therefore, these chemicals are synthtically processed in a laboratory and are not ‘natural’, as many may tend to believe.
Does Raspberry Ketone Work?
A study carried out with a small number of people who were given a daily dosage of 200 mg of ketones plus 1,200 mg of vitamin C over a period of one month showed that it worked. Most people who were part of the study lost significant amounts of body fat.
How Raspberry Ketones Work?
Researchers became interested in ketones as a potential weigh loss ingredient fater they discovered the structural similarity of its molecules with those of synephrine and capsaicin molecules. Both these ingredients were known to work as effective fat burning ingredient and it was thus conjectured that raspberry ketones will be abel to do the same, too.
According to the studies available till date, ketones aid weight loss by boosting metabolism. The ingredient makes the cells more sensitive to the effects of norepinephrine, which is a fat burning hormone found in human and other mammals. At the same time, it also boosts the production of hormone adiponectin which helps regulate metabolism and aids fat burning.
Not much scientific data are available as to whether or not raspberry ketones come with any potential side effects. They are considered safe for use in foods and cosmetics, but it is still not known whether the dosage used in the supplements can have any side effects or food or drug interaction.
