Dinitrophenol Review - 5 Things You Need to Know


The results of my research into Dinitrophenol were somewhat surprising. We at DietSpotlight conducted an in-depth review, examining the side effects, ingredients, scientific research and level of customer service. We also sorted through hundreds of user comments and remarks that are posted online. Lastly, we summed up all of the facts and feedback we found in order to give you the bottom line.

What is Dinitrophenol?

To begin with, Dinitrophenol ingredients simply include DNP or 2, 4-Dinitrophenol. This is not a supplement with several components, but rather a single substance that is sometimes used for weight-loss purposes. The claim is that it helps increase metabolism, which results in significant weight reduction. No special diet plan or fitness regimen is needed. You simply take this product daily (200-400 milligrams) and can potentially see fast results. Some serious weight lifters and bodybuilders use DNP.

We are not sure when Dinitrophenol first emerged. However, we do know this substance affects mitochondrial ATP production. This in turn increases the body’s production of heat. There is some user feedback posted online to help you gain a better understanding of DNP, but read on…

Adverse Effects – “Is It Worth It?”

The first concern we have is Dinitrophenol side effects. According to our Research Editor, “DNP can cause serious adverse reactions, such as breathing problems, irregular heartbeat, and even death. This is cited on websites like NCBI.gov.”

On the other hand, a different user commented, “Been taking this a few days. Wow, makes me really hot.”

Another posted, “Going to be honest, this stuff is dangerous. Causes insomnia too.”

Customer Warnings – “Be Careful”

There are quite a few customer warnings about Dinitrophenol. In fact, one person revealed, “My son died taking this. Don’t use it. It killed him 8/31/2015.”

Then again, a different user had this to say, “Does increase your body’s core temperature. But, you need to be prepared for some side effects.”

“A bit too intense for me. Thought it would help me cut fat, but no thanks,” mentioned another individual.

Our research has revealed that if there is some particular part of a weight-loss pill or diet program that is especially troublesome (adverse effects, customer warnings, steep price) the probability of real results for the long term is low. In other words, if Dinitrophenol does in fact cause serious side effects in a lot of people, this could be a deal breaker.

The Science – “Is There Any?”

Here at DietSpotlight, we need to see some actual research that supports the product we’re investigating. Unfortunately, though science does support claims of increased heat production and weight-loss, taking even a small amount too much can lead to death.

The Bottom Line – Does Dinitrophenol Work?

Now the moment you’ve been waiting for. This is our bottom line on Dinitrophenol. First off, we appreciate that this substance can potentially elevate metabolism. Also, we’re very leery of this ingredient because of the discouraging customer comments we found posted on the web.

If you’d like to get rid of some pounds, then we encourage you to go with a product that contains clinically tested ingredients for weight-loss, does not cause any dangerous or deadly reactions and is supported by positive user feedback.

Among the best products we’ve seen this year is one called Dietspotlight Burn. Its formula is a proprietary blend of four key ingredients, which have been shown in published clinical research to help accelerate fat loss and boost metabolism. We can’t find any discouraging user reviews online, and comments around the web indicate people are seeing great results.

The makers of Dietspotlight Burn are so confident in their product they’re offering a special trial offer, which is very encouraging.

Previous Dinitrophenol Review (Updated January 26, 2010):

The current weight loss market is loaded with supplements that contain "key active ingredients." This is where Dinitrophenol comes into the picture. It's a bit unclear whether or not this substance is only for prescription weight reduction products or not. After doing a bit of online research, it appears that Dinitrophenol, which is also commonly referred to as DNP, is used for weight loss because it aids the user's metabolism. However, there are some side effects that can occur with this ingredient. The key is consulting a real physician before ever attempting to take DNP. According to certain online sources like dnpweb.com, Dinitrophenol "accomplishes an outstanding increase in metabolic rates" by inhibiting the "F0F1 ATP Synthase Molecule," which is clarified to be located inside the mitochondrial wall. Now, you may be wondering what exactly that means for individuals who're struggling to shed excess body fat. Well, by taking Dinitrophenol and maintaining the same diet plan, you may be able to burn of up to "20-40 percent more calories" each day. This is without even adopting a regular fitness routine. Although I found two online sources that sold Dinitrophenol-based supplements, both appeared to be discontinued. It's common for DNP to be used by bodybuilders.
