Thermoxyn Review - Does This Weight-Loss Supplement Really Work? Are dangerous ingredients and user complaints deal breakers?

Editor's Review: 4.0 / 5.0
Thermoxyn Review

Thermoxyn company employees, have you ever taken your own product? There’s been plenty of discussion regarding this supplement for weight-loss, so we did an in-depth review, examining the side effects, ingredients, scientific research and overall customer care. Furthermore, we spent hours reading dozens of dieter and user comments from around the web. Lastly, we condensed all of the data we found to give you the info you actually need.

EDITOR'S TIP: Substitute Thermoxyn with a proven fat burner such as Leptigen for better results.

What You Need To Know

To start, Thermoxyn is marketed as a thermogenic weight-loss solution. The ingredients include caffeine, theacrine, citrus aurantium, rauwolfia serpentina, lemon verbena, raspberry ketones, green coffee bean extract, garcinia cambogia and olea europa leaf. This formula can be taken daily (no more than four capsules) to potentially help with energy enhancement, increased metabolism, muscle retention and fat loss.

It appears that Thermoxyn was first released in 2013 and it’s available on the official website for $39.99 (120 capsules). This supplement contains natural ingredients and may help boost energy levels, but read on…

Dangerous Ingredients – “Watch Out?”

Our first issue with Thermoxyn ingredients, was the potential for adverse reactions. “You should always be aware of the formula that makes up any supplements you take. As for this one, it contains citrus aurantium, which can lead to side effects like jitters, rapid heartbeat and increased blood pressure,” says our Research Editor.

One customer said, “Makes me a bit sick to my stomach.”

Another user stated, “This stuff is not safe. Can cause serious jitteriness and fast heartbeat.”

Customer Complaints – “Another Concern”

Some users have complained that Thermoxyn simply does not work as claimed. One dieter said, “No actual weight loss here. Felt some energy, but no weight loss.”

Another customer offered, “Not sure if this is healthy. I don’t feel well after taking.”

Our research has revealed that if a certain facet of a diet pill or weight-loss system is especially problematic (too many user complaints, dangerous ingredients, high price) the likelihood of success for the long run is slim. In other words, if Thermoxyn does result in numerous customer issues, this could be troublesome.

The Science – “Any Validity?”

Even though Thermoxyn is touted as a very potent supplement for weight-loss, there is no clinical data presented to prove this that focuses just on this product. Caffeine does have support that proves it can boost energy, but there’s also research that shows citrus aurantium can cause side effects. We at DietSpotlight really need to see published science that supports Thermoxyn to give it a thumb up.

The Bottom Line – Does Thermoxyn Work?

So now, what’s the final word on this product? We are glad to see that the ingredients used in Thermoxyn capsules are posted and explained on the official website, but we’re not sold because the key element, citrus aurantium, may not be safe. It has actually been compared to ephedra, which is a bad thing. Also, Thermoxyn relies on fads like raspberry ketones and garcinia cambogia, which have not been proven to work for weight-loss. No customer testimonials were found on the main website, either.

If you would like to lose weight faster and rock your best body, we recommend a diet supplement that contains safe ingredients, is backed by real science and is also supported by positive user feedback.

Among the best products we’ve seen in 2016 is one called Leptigen. This supplement contains a proprietary blend of four important ingredients, which have been proven in published clinical studies to help kick-start metabolism and improve fat loss. We are unable to find any complaints of harmful side effects and user reviews on the internet express people are seeing significant results.

Plus, the company behind Leptigen is quite confident in the formula so they’re offering a Special Trial Offer, which is a good sign.

What You Should Know

There is no official website for Thermoxyn, but those who sell Thermoxyn online do give us some product information about it. We are told that Thermoxyn is a revolutionary development for people concerned with maintaining muscle while, at the same time, "shredding" body fat. Thermoxyn contains a large number of ingredients. The major active ingredients in Thermoxyn such as Yerba Mate, Green Tea Extract and Citrus Aurantium can be commonly found in a whole host of other weight loss products on the market today. Those who know anything about weight loss products will know that Green Tea Extract is one of the most popular ingredients in weight loss products on the market today. Citrus Aurantium, which was at one time thought to be a safe alternative to the banned stimulant Ephedrine, is now causing controversy as many experts now believe that it may increase the risk of a stroke or heart attack.


The ingredients in Thermoxyn consist of: Guarana Extract, Citrus Aurantium, Green Tea Extract, White Willow, Angelica Dahurica Va-Pai-Chi Root, Oloong Tea Extract, Theobroma Locoa Extract, Yerba Mate, Theobromine, L-Tyrosine, L-Caritine, and Coleus Forskholii.

Product Features

We are told that you should take three capsules of Thermoxyn thirty to sixty minutes before exercise, and that you should not exceed more than twelve tables per day. The product information for Thermoxyn informs us that you should fist seek your physician's advice before taking Thermoxyn if you suffer from diabetes, thyroid irregularity, disorders, or seizure disorders. In fact there is a long list of warnings for Thermoxyn, and therefore anyone considering taking Thermoxyn should first read very carefully the listed contraindications. Thermoxyn can be ordered directly on line at a price of $28.99 for 90 tablets.

Thermoxyn is certainly marketed towards those who work out regularly and who want to lose weight at the same time. It certainly does not seem to be the most suitable product for the ordinary man or woman who would simply like to lose a few pounds. However even if you are someone who works our regularly and are tempted by the idea of taking Thermoxyn, there is little info given that allows us to compare it to rival diet aids on the market today.

    Just wanted to tell you that some of your information in your rating is wrong. I am currently using thermoxyn. They do have a website and the back of the bottle states that you shoul not take more than 4 in a 24 hr period. Also, some of the ingredients you have listed are not listed on the bottle. It makes me wonder if you have a bias. At least tell the truth about what is in it…



    Is this product an approved product for bodybuilding organizations?
