Do Raspberry Ketones Really Work?

Many people, if not most take supplements when they are trying to lose weight. One of the most popular weight loss supplements available are Raspberry Ketones.

The claim is that the Raspberry Ketones help to break down the fat within the cells more effectively. This helps the body to burn fat faster. An additional effect is that the hormone level for adiponectin, which helps to regulate the metabolism, is increased.

What exactly are Raspberry Ketones?

At first glance everybody would stop reading at the word ‘raspberry’ and instantly assume that this must be a natural ingredient. That is unfortunately not the case. Raspberry ketone found in supplements is artificially created.

However, it does occur in Raspberries naturally. Unfortunately in such low quantities that you’d need to eat around 90 pounds of raspberries to get the dosage of one pill. In the raspberries the ketones are responsible for the powerful aroma of the fruit.

You can also find the raspberry ketones being used as a flavor enhancer in soft drinks and ice creams. They also have been used in cosmetics for many years.

How do Raspberry Ketones work?

The molecular structure of raspberry ketones is what made researchers interested in them. They have a similarity to capsaicin which is found in chili peppers and synephrine which is a stimulant.

Studies with these two compounds have shown that they can boost the metabolism. The hope was that raspberry ketones would work similar due to their similarities.

Studies were performed with rats to research the impact of raspberry ketones on the metabolism and the absorption of fat in the body. The results were promising enough to know that they can help with breaking down fat in the body. They also do increase the levels of a hormone called adiponectin which is believed to help regulate the metabolism and levels of blood sugar.

Adiponectin is found in higher levels in people that are not overweight. Similarly it is found in lower levels in people that are overweight. The hormone is not only increased by being thin or using raspberry ketones. Exercising dose increase the levels in a very short period of time. Consuming coffee can also increase the levels in your body.

Do Raspberry Ketones Work?

Many people have used raspberry ketones and reported that they helped them lose weight. Yet, there are no studies that can scientifically prove those results.

Theoretically, they should help to lose weight. The best chances to work are if you combine them with an overall healthier diet. This will be like a one-two punch to your high weight.

Using raspberry ketones certainly will not allow you to start eating anything you want. You will have to be mindful of what you eat and how much you eat. Combining these factors with a weight loss supplement like raspberry ketones will definitely help you to lose weight and get healthier.

Side Effects

There are no serious side effects known to come from raspberry ketones. Very few people mention increased heart rate and jitteriness. Some even mentioned an increase in blood pressure.

It’s hard to point those very few instances back to the usage of the supplement. However, to be safe, you want to always discuss using any supplements with your doctor before you start using them!


There is no generally recommended dosage. This is due to not having any scientific studies that evaluate the levels consumed by humans. In the formerly mentioned studies with rats, the dosage was extremely high.

There were no side effects on those rats so it is to assume that even higher dosage will not have any health impact on humans. The different providers of raspberry ketones suggest recommended dosages of up to 400mg taken twice a day. You should in any case make sure to follow the recommendations from the supplement provider in the directions.

Is it worth trying Raspberry Ketones?

There doesn’t seem to be a lot of evidence that would suggest that you should try them when you want to lose weight. However, there’s also not much evidence to suggest that you shouldn’t.

Overall, people have reported that they lost weight when using them. In many cases not a lot but sometimes losing a little steadily is better than a lot at once which then comes back.

So, don’t expect wonders from taking this supplement. You can expect some weight loss. It’s not the magic wonder supplement that will help you lose 20 pounds in your sleep. On the other hand, there’s no such supplement anywhere…
