Xtreme Thermoburn Review - 6 Things You Need to Know


It’s been a long journey but I feel I’m now qualified to advise you on whether or not to take Xtreme Thermoburn. We dug deep into the ingredients, side effects, scientific research and customer service. Furthermore, we scrutinized hundreds of consumer comments and reviews. We then refined and summarized to give you the info you need.

What You Need to Know

To begin with, Xtreme Thermoburn is a fat burner, containing ma huang, green tea extract, caffeine, garcinia cambogia, citrus aurantium, white willow bark, acetyl l-carnitine, ginger root, cayenne fruit extract and chromium. The recommended dose is two capsules per day, which is supposed to help promote weight-loss. One of the benefits is the compact size.

There is no information relating to when Century Supplements introduced the diet pill. We did notice that Xtreme Thermoburn appears to be free of synthetic ingredients, a good choice. You can buy it on the official website and through trusted retailers. We do like the product availability and that it’s easy to use, but read on…

Effectiveness – “Doesn’t Work?”

The first concern we had with Xtreme Thermoburn ingredients was lack of effectiveness. “Several fat burners on the market contain caffeine, a stimulant shown to assist with weight-loss,” said our Research Editor. “Despite the fact that this supplement contains enough, actually more than enough, there are still reports of dieters seeing no results.”

“I have been taking these for 1 week now and I have to say I am very disappointed. I have put on 2 lbs and I’m not happy, I eat healthy as I am a member of my local slimming world group and I also exercise nearly every day,” said a user.

“Had high hopes when I first took these but found them to be very disappointing. Apart from sweaty armpits no weight loss at all. I’ve being working out 5 times a week and haven’t noticed anything from the norm,” reported a customer.

Illegal Ingredients – “Bad Choice”

The FDA has removed ma huang from the market stating, “We’ve issued a rule banning ephedra-containing products and we’re sparing no effort to stop their manufacture and distribution. If any of these dietary supplements are still on the store shelves, I urge the retailers to stop selling them immediately.” The agency started telling dieters about the potential side effects years before the recall. “FDA has warned consumers against the use of dietary supplements containing ephedra since June, 1997, and banned these products after research confirmed that ephedrine alkaloids raise blood pressure and otherwise stress the circulatory system.”

Customer Service – “Poor Quality”

According to some forums, Xtreme Thermoburn representatives aren’t supportive. “Quite simply put unacceptable delivery time. Been waiting for almost a month for a small package to arrive, we do not live in the Middle Ages very quick to accept payment but very slow to deliver,” claims a customer.

“Wouldn’t use this site again to be honest it is unreliable. I placed an order 2 weeks ago and I have still not received confirmation or notifications about what stage my order is at! Not happy with the order process at all!,” offers a consumer.

“You are still billing my credit card when you said you would credit the last three billings, I have returned the products,” said a dieter.

Our research concludes that if an issue is problematic, like poor customer service, this could put a damper on long-term success. If the consumer support team at Xtreme Thermoburn is unhelpful, there’s a concern.

The Science – “Valid?”

According to the official website and other retailers, the supplement includes a formula that will burn fat, increase metabolic rate and suppress appetite. All of these claims are attributed, on some level, to the caffeine. But, we’re more concerned with the synephrine and ma huang (ephedra). Both are associated with some pretty nasty side effects.

The Bottom Line – Does Xtreme Thermoburn Work?

Well now, shall we take a final look at this supplement? There are some positives like the availability of the product and a few favorable comments, but we have doubts about recommending it because we’re concerned about the unhelpful customer service department. Plus, the formula contains a banned ingredient and a stimulant known to cause side effects.

If you’d like to slim your waistline, we recommend going with a strong customer service department and safe ingredients backed by published clinical studies that aren’t associated with side effects.

Among the best products we’ve seen this year is one called Dietspotlight Burn. The formula contains a four-ingredient proprietary blend, which has been shown in studies to help ignite fat loss and increase metabolism. We can’t find a single mention of side effects and reviews on the web say customers are noticing exceptional results.

The company behind Dietspotlight Burn is so confident in the supplement, they’re providing a Special Trial Offer, a good decision.

What You Should Know

Xtreme Thermoburn is a dietary supplement manufactured by Century Supplements. The company is based in the UK, with offices in the United States. The goal of the company is to provide a place where fitness enthusiasts, bodybuilders and the average dieters can purchase dietary supplements designed to improve overall health and wellness.

For years, dieters searched for products containing the legendary ECA stack, especially in the US. The combination of ephedrine, caffeine and aspirin did produce weight loss, but the health ramifications were severe. There were reports of strokes, heart attacks and death associated with consuming the ECA stack. Did Century recreate the “magic” diet pill or is Xtreme Thermoburn just an updated version of the same potentially dangerous diet pill?

List of Ingredients


  • Ma Huang
  • Caffeine
  • Garcenia Cambogia
  • Citrus Aurantium 4%
  • White willow bark
  • Acetyl L-Carnitine
  • Ginger Root
  • Cayenne
  • Chromium Picolinate

Product Features

Xtreme Thermoburn is dietary supplements claiming to produce increased energy, weight loss and appetite suppression. The supplement is available on the official website for £45.95. Customers in the U.S. do not have the ability to purchase the product due to the ban on ephedrine in the U.S. The website does offer a money back guarantee for any reason. The supplement is expensive compared to similar product on the market.

The ingredients are a laundry list of stimulants. Within one serving, dieters consume 500mg of caffeine, Ma Huang and Citrus Aurantium. There is the change health issues could potentially occur when taking this large amount of stimulants. There is also the concern relating to individuals with mental health issues. This product is not an ideal solution.


  • The supplement is available on the official website.
  • Dieters have the opportunity to review the ingredients on the website.


  • Xtreme Thermoburn is expensive.
  • Xtreme Thermoburn is not available to U.S. customers.
  • The supplement is not designed for individuals sensitive to caffeine.
  • The supplement contains an excessive amount of stimulants.
  • There is not guarantee the supplement will assist with weight loss.
  • The use of Xtreme Thermoburn could potentially affect heart health.


Xtreme Thermoburn is one of the most extreme fat burners on the market. Not only does the supplement contain 200mg of caffeine per serving, there is 200mg of Ma Huang (ephedrine) and 100mg of Citrus Aurantium. Just with those three ingredients, dieters consume 500mg of stimulants. We have to note this is a potentially dangerous combination of stimulants.

Xtreme Thermoburn attempts to recreate the ECA stack, just with different names for the original supplements. Although the ECA did work, there is no evidence Xtreme Thermoburn is effective with weight management. Weight loss is not an overnight process; it takes hard work and dedication, not an extreme thermogenic diet pill.

    Hi, Robert, we recommend you contact this company with the information provided in the Q&A section.

  •  Nothing More than Caffeine
    Deborah (Verified User)

    This is nothing more than caffeine. Nothing like the old metabolife 356. If it has any ephedra in it, it is so minuscule that it won’t have any effect. Reviews are screwed because negative one are filtered out of most sites as they are paid to advertise this product.
