DEX C20™ Fat Burner Reviewed: The Indian Appetite Suppressant?

According to the advertising literature, DEX-C20™ can help you burn additional calories, increase your energy, and decrease your appetite dramatically.

And this, all thanks to a miraculous plant from India called “Caralluma fimbriata.”

The product’s web site claims that “DEX-C20™ is backed by four (4) human clinical trials, multiple safety studies, and University reviews…” (of course they don’t happen to reference any of this “credible scientific validation” by name).

Funny thing though, when I went to PubMed to check out these studies, I wasn’t able to find anything under “DEX-C20™.”

I did, however, find one positive study on Caralluma (see Appetite. 2007 May;48(3):338-44. Epub 2006 Nov 13). It concluded…

“While there was a trend towards a greater decrease in body weight, body mass index, hip circumference, body fat and energy intake between assessment time points in the experimental group, these were not significantly different between experimental and placebo groups. Caralluma extract appears to suppress appetite, and reduce waist circumference when compared to placebo over a 2 month period.”

While positive, I would hardly describe the results of this study as a rip-roaring endorsement of Caralluma’s amazing fat burning and appetite suppressing powers.

Incidentally, it also appears to be the only published, peer-reviewed study on Caralluma’s possible benefits for dieters. I couldn’t find any of the other “human clinical trials” referenced by retailers. If these studies do exist, it is likely they are “in house” studies; studies done by the manufacturer or retailer of the product.

If there is a positive side to this, it’s that a daily dosage of DEX-C20™ contains 1 gram of Caralluma — the exact amount the participants in the study referenced above received.

DEX-C20™ also contains a blend of 10 ingredients, a…

“…breakthrough herbal blend that increases calorie burning and is stimulant-free.”

Problem is, this proprietary blend only contains 60 mg of ingredients. And that means that none of these ingredients are present in anywhere near the dosage necessary to elicit any sort of effect. It’s marketing and label decoration, pure and simple.

Originally I believed DEX-C20™ contained Citrus aurantium, a known stimulant. It does not. It actually contains Citri aurantii (orange blossom), which is not a stimulant.

The foundation of the DEX-C20™ weight loss product, therefore, is its Caralluma fimbriata content. Is this an amazing natural appetite suppressant? Will it help you to lose weight?

As of now, there is only a single, published, positive peer reviewed study for Caralluma. And single small studies can scarcely be considered “irrefutable proof” — it is not uncommon, for instance, for follow up studies to demonstrate completely contrary results.

At the same time, I have been contacted several times by Nate Bernstein, VP of Sales and Marketing of DelMar Labs, the company who makes DEX-C20™. Mr. Bernstein has indicated to me that his company has seen to undertake a large scale, double-blind clinical trial on their DEX-C20™ product , and this study will be published next year (Mr. Bernstein assures me additional positive studies will also be published on Slimaluma, the patented version of Caralluma fimbriata).

Mr. Bernstein has asked me to share the results of these studies with our visitors, and I welcome the opportunity to do so.

In the meantime, if you’re curious about Slimaluma, you can purchase it very inexpensively from (this product also contains green tea and yerba mate, which provides it with 20 mg of caffeine).

Summary of Dex-C20
  • Backed by some research.
  • Relatively simple formula.
  • Additional herbal blend is strictly “label dressing”
  • Don’t expect miracles.

  1. I just wanted to add I purchased this a couple of weeks ago and it does work to control my appetite.

    I have used hoodia and it does not work for me at all. In order to eat I have to take the pill right before I take my first bite of food. Because if I wait an hour, I have no desire to eat. I have to force myself to eat.

    I purchased this because it was cheap (15 bucks) and I have tried almost everything. This stuff works great!

  2. I have taken this supplement on and off for the last couple months. I find that it completely wipes out your desire to eat as well. You do have to force yourself if you don’t eat right away.

    I feel it has also made me a bit more scatterbrained. I also experience more vivid dreams while taking this supplement.

    I did lose weight because I didn’t snack, but it was also hard for me to even eat a full meal. As soon as I stopped taking the pills, some of the pounds came back because my metabolism was so out of whack.

    I think in small doses it is beneficial to prevent excessive snacking but it is important to eat right before or right after you take it.

  3. I took this for about three weeks. It does dramatically reduce appetite. But, like Natasha, I discovered that as soon as I stopped I gained tons of weight because my metabolism was so low from not eating. I also experienced unexplained infections (two ear infections in three weeks, when I hadn’t had one since I was a small child, an inexplicably swollen eye, wounds not healing). I can’t say or sure that these were caused by Dex-C20, but they started when I started taking it and stopped when I stopped.

  4. It seemed to help me initially with maintaining my weight but now, not so much. Like most supressants it seems to stop working after about 1 or 2 months. I’ve been using it for about 5 months but I think it’s run it’s coarse for me.

  5. I’ve been taking Dex for about 3 weeks now and it completely takes away your appetite. I have lost 3 lbs. It also makes your stool very soft. It works very well but sometimes it sucks because sometimes there is something you really want to eat and you can’t even if you dont take it that day – it seems it is still in your system. I say buy this product and its so cheap.

  6. This product does not do anything so I stopped using it. Without it, I have lost 15lbs and counting. I will give it another try. Short of throwing it in the trash there is nothing else to do with it. I saw no decrease in appetite other than overcoming my urges mentally.

  7. This works great! I bought it a month ago and I have lost 15 pounds with no exercise at all because I have a broken leg. Buy this its amazing. ALL these comments that say it doesn’t work are completely untrue! It works amazingly well – I bought 6 bottles of it!

    Editor’s comments: Melissa, we’re glad you like this product, but your positive experience does not the negate the negative experiences of others. It’s not uncommon for people to have different experiences with different products, so don’t dismiss them outright if they don’t align with yours.

      • Maribel, I’m glad you found this product helpful but that doesn’t mean that those who don’t experience similar results have a hidden agenda. This isn’t a drug after all, and there’s very little clinical evidence to support the claims being made for it.

  8. It worked for me… in 3 months I lost almost 20 pounds! However, there was some light exercise involved – like walking at the park at least 3x per week and on average I didn’t go over 1200-1250 calories per day.

    It worked for me! If you wanna lose the weight and not spend too much money, a box runs about $20… I say go for it!

  9. DEX-C20 was the start of my life after my 2nd child. This product worked for me. I wasn’t as hungry, I had energy to work out more and I always felt motivated because I was losing 8-14 pds a month.

    Every month was like a challenge. Uou have to give it try. You have to use it for one month before you start seeing any results. Good luck. I went from 158 to 102.

    I’m very happy with my figure.
