Raspberry Ketones Review- Does This Natural Extract Work?
The results of my research into raspberry ketones were somewhat surprising. We took a closer look at the side effects, ingredients and clinical studies. Additionally, we sorted through hundreds of user responses and comments from around the web. At this point, we condensed and summarized to give you the info you need.
What are Raspberry Ketones?
To start with, raspberry ketones are derived from red raspberries. This is a chemical that is sometimes used to manufacture fragrances, foods and cosmetics. It has a potent flavor and aroma. Furthermore, this substance is used in a number of over-the-counter weight-loss supplements. This ingredient may help elevate adiponectin (a hormone) levels, which in turn aids with fat reduction. It is also a natural component that provides some antioxidants. This ingredient is often combined with other natural herbs as well.
We are not sure when the first raspberry ketones weight-loss supplements were released. However, this ingredient gained a lot of popularity after being discussed on television programs in 2012. As a product, you can purchase it at local retailers and through online stores. We like that it’s natural and that we found some positive customer comments, but read on…
Fad Ingredient – “Concerned?”
One concern we have is with raspberry ketones ingredients. “There is no solid clinical evidence that supports this fruit extract as an effective weight-loss aid,” said our Research Editor. “WebMD even states that this substance has not been proven to help treat obesity.”
One user stated, “These did absolutely nothing for me. No change in how I felt. No extra energy. Nothing.”
Then again, a different customer said, “Hoping for some weight-loss. Been taking this for a few days and eating well, but I don’t feel a difference yet. No raspberry ketones side effects either.”
Another posted, “These are fairly easy to take. Not sure if they are working though.”
Minimal Results – “Losing Weight with Raspberry Ketones?”
According to raspberry ketone reviews, dieters aren’t exactly noticing results. One person revealed, “Waste of money. I did not notice a difference in my appetite or weight.”
“Still not sure about this one. Been taking a month and have dropped a pound,” commented another.
However, a different customer said, “Didn’t work much for me, but my wife said she liked it.”
“I have noticed some results from these raspberry ketones pills,” posted another.
The research we’ve done has shown if there’s a specific part of a diet product that’s concerning, like being ineffective, the chances of long-term success are limited. If raspberry ketones fail to produce real results, this could be a dilemma.
The Science – “Solid?”
Although some research has been conducted with raspberry ketones, it is inconclusive at this point. There are no clinical studies that truly support this ingredient as an effective weight-loss aid. We at DietSpotlight look for solid science that backs any claims. With this one, there’s nothing available.
The Bottom Line – Does Raspberry Ketones Work?
Now the moment you’ve been waiting for. Here is our bottom line on raspberry ketones. We like that it’s readiliy available and that we found some positive customer comments. On the other hand, we have some concerns because it’s not backed by any solid science. Moreover, we’re also skpeitcal about this one due to discouraging customer comments and that it’s considered a fad ingredient.
If you’d like to drop more weight, we suggest going with a product that is backed by solid clinical research, supported by encouraging user reviews and gives you a lot of bang for your buck.
Among the best products we’ve seen this year is one called Dietspotlight Burn. Its formula contains four clinicially-tested ingredients, which have been shown to help speed up fat loss and boost metabolism. There’s no talk of harmful side efffects and the comments around the web indicate people are seeing great results.
The makers of Dietspotlight Burn are so confident in their supplement, that they’re offering a Special Trial Offer.

What You Should Know about Raspberry Ketones
Raspberry Ketones are one hot ingredient in the weight loss world right now. The push behind this ingredient is a series of clinical studies claiming raspberry ketones will increase fat loss, naturally, without stimulation. The studies have been completed on animals so the effect on humans may not be as prevalent, but that does not take away from the buzz. The power of raspberry ketones rests with adiponcetin. The more adiponcetin available in the body, the less body fat.
List of Ingredients
- Raspberry Ketones
Product Features of Raspberry Ketones
The inner workings of raspberry ketones are rather simple. According to animal research, raspberry ketones increase adiponcetin. When there is more adiponcetin is the body, fat loss tends to occur rapidly. Many of the clinical studies involve feeding rats a high fat diet before giving them injections of raspberry ketones. This raises a red flag. If the clinical studies are based on injections, does the dieter have to take the supplement via injection to promote fat loss?
There is another problem with the ingredient. We found reference to a human study that was not published officially. The study showed minimal differences in humans taking raspberry ketones and those taking a placebo. Much of the information online about the ingredient comes in the form of personal accounts from dieters having taken the supplement. While this information is important, without clinical studies supporting raspberry ketones specifically, there could be a number of reasons why these dieters lost weight taking the ingredient or a supplement containing the ingredient.
The placebo effect is strong and can be enough to promote weight loss. Dr. Oz, a celebrity doctor and weight loss expert, claims raspberry ketones work to reduce body fat. This support may be more than enough to promote the placebo effect in dieters.
Advantages of Rapsberry Ketones
- Animal studies show fat loss after taking the supplement.
- Supported by Dr. Oz.
Disadvantages of Raspberry Ketones
- No clinical studies on humans are available.
- One human study showed no significant weight loss (not published.)
There are plenty of clinically proven weight loss ingredients, including chromium, caffeine and green tea. If a supplement contains raspberry ketones along with these ingredients, we are all for trying the supplement, but only if the proven ingredients are included in proven amounts. Too many supplement companies will list clinical data supporting a supplement, only to list ingredients in a proprietary blend.
Dieters need to increase exercise and decrease food intake to lose weight. The effect of raspberry ketones is not strong enough to help a dieter lose weight without strong life changes. With future human studies, we may support raspberry ketones, but as of now, there are no studies to support any effect on humans.
Raspberry Ketones Side Effects:
We have completed a thorough look into raspberry ketones, but we felt the need to take things even further, so we dissected it to find raspberry ketones side effects. Ingredients and clinical research were taken to heart. Customer comments and experiences by the hundreds took a strong role in the outcome. Then, we summarized the info to give you the bottom line.
What You Need to Know
To begin with, raspberry ketones is a weight-loss ingredient extracted from the fruit. When it was promoted on the Dr. Oz show it gained instant stardom. You take the supplement multiple times daily, with detailed instructions available on the label of the product you choose. Claims range from decreased appetite to increased metabolism. There’s no issue taking this one with you on the go.
The product, first widely introduced to the world in 2002 by Dr. Mehmet Oz, is all natural, a good sign. There is no shortage of options if you want to buy it online or offline. We do like that the price is low and that some dieters are happy with the results, but read on…
Weight Gain – “Up and up!”
Our first concern with raspberry ketones side effects is weight gain. “This supplement is supposed to help the dieter lose more,” says our Research Editor. “This idea that you could come away heavier is not one users want to consider.”
“I did not loose any weight and in fact gained a pound and a half,” a user explains.
“The next morning, I gained weight and so did my boyfriend. We gained weight for a few days,” offers another disappointed buyer.
Moving the scale up is a common complaint, “Trust me, I didn’t lose any weight and actually gained a couple of pounds.”
Stomach Discomfort – “Ouch!”
There’s also the issue of stomach discomfort as one of the raspberry ketones side effects. “Twisted my stomach one day of just taking two pills for the day, got me constipated, my head was throbing so much, I threw up,” a dieter reveals.
“I experienced some cramping and stomach upset, along with a headache,” divulges another.
Sometimes it took a short time to feel the effects, “I only used this once (one pill) and started having bad stomach cramps and the runs.”
It’s based on our research that we’ve found a connection between small issues, like weight gain, and reduced chances of long-term success. If raspberry ketones makes the dieter’s scale go up, that’s not what they want to see.
You will find companies selling raspberry ketones offering links to clinical studies proving some effect on weight-loss, but look closely. We found one from Planta Medica that involved male mice. Another from the journal Life Sciences was also completed on rodents. There is no research supporting claims that you’ll lose more weight based on human results. At DietSpotlight we want to see people reporting great outcomes. If the only data involves animals, why would a human take that into consideration?
The Bottom Line
It was with great interest that we looked at the details about raspberry ketones side effects. We do like that you can find it just about anywhere and that some dieters like their results, but we can’t recommend it because there’s no clinical proof from human trials. We’re also concerned the rise in popularity was associated more with celebrity endorsement than efficacy.
If you’re in the mood to make those pounds disappear, we suggest going with a supplement that doesn’t have dieters worrying about side effects and that’s formulated with clinically proven ingredients.
Among the best of all supplements we’ve found in 2015 is one called Dietspotlight Burn. There are four ingredients in the proprietary blend, all clinically proven to help crank up metabolism and fat loss. There are no reports of harmful side effects of any kind and dieters report being happy with the good results they’re seeing.
Also, the people behind Dietspotlight Burn are so confident in the formula that they’re offering a Special Trial Offer, good sign.
