So What Is Nutrabolics Thermal XTC and What Are The Ingredients?

The ingredients used in Nutrabolics Thermal XTC are listed below. The ingredient quantities provided are per serving of three capsules.

  • L-Tyrosine 1140 mg: Some people use Tyrosine as an appetite suppressant, but there is little clinical evidence that it is effective for this use. Large doses of tyrosine may be useful for increasing alertness, especially in people who are sleep deprived.
  • Green Coffee Bean Extract (Coffee Arabica seed) 300 mg (standardised to 5% caffeine and 50% chlorogenic acids): Contains caffeine. Whilst it was thought that this ingredient was a significant aid in weight loss, the relevant research has been discredited as it was fraudulent. Currently there is no evidence that it aids with weight loss more than any other source of caffeine. See our article for more details:
  • Caffeine Anhydrous 135 mg: Numerous studies have shown that caffeine boosts energy levels and alertness, as well as mildly boosting the metabolism. The effects shown in studies are small, and some studies are inconclusive.
  • Malabar Tamarind (Garcinia gummi-gutta, fruit peel) 100 mg (50% Hydroxycitric acid): The Malabar Tamarind is more commonly known as Garcinia Cambogia. Garcinia Cambogia: Test tube and animal research suggests that HCA, the active compound in Garcinia Cambogia, may be helpful in weight loss because of its effects on metabolism. However, numerous studies in humans have found it has no effect upon either appetite or metabolic rate.
  • African Wild Mango (Irvingiagabonensis, seed) 100 mg: Whilst many of the studies of African Mango have been funded by supplement manufacturers (which makes them automatically biased), there are promising preliminary results that suggest IGOB131, a substance extracted from African Mango seeds, supresses the appetite and leads to weight loss. It is unclear whether that precise extract is used here.
  • Green Tea Extract (Camellia Sinensis, leaf) 100 mg: Green tea is high in a group of antioxidants called catechins. Studies have suggested that catechins increase thermogenesis in the body, whilst caffeine increases energy expenditure by boosting the metabolism slightly for few hours.
  • Evodia (Tetradiumretucarpum, fruit) 1% evodiamine 100 mg: Evodia is a plant that is thought by some to be a thermogenic weight loss aid; the main ‘active’ compound is evodiamine. Clinical evidence is sparse, and no research has been conducted in humans. Studies in rats also show that it reduces the effectiveness of caffeine, and causes caffeine to break down much quicker.
  • Chundan (Salacia reticulate, leaf) 100 mg: when taken in high doses (240mg-1gram), this plant appears to act as a carbohydrate blocker. In lower doses it appears to lower blood sugar levels.
  • Nutmeg (Myristicafragrans, seed) 50 mg: May act as an aphrodisiac, based upon studies in rats and has been used in herbal medicine to soothe an upset stomach.
  • Guggulsterone (Commiphorawightii- gum oleoresin) 25 mg: Guggul extract is taken from the sap of a tree native to India. Currently, evidence that Guggul is useful for weight loss is preliminary, with mixed results from the few trials already conducted upon it, with some suggesting that Guggul has no effect upon weight loss, whilst others suggest its effect is moderate.
  • Gamma-Butyrobetaine 25 mg: an enzyme used in the production of L-carnitine in the body.

So What Does All This Mean?

Garcinia Cambogia is seemingly a fairly unpredictable weight loss aid. In one study that is often misquoted, the participants who took garcinia cambogia did lose weight whilst on the trial, but the placebo-taking group actually lost significantly more weight than the garcinia cambogia-taking group. There are also studies that show no changes in metabolism, appetite or weight loss whilst using garcinia cambogia. At best, Garcinia Cambogia could aid weight loss in some people, but its mechanisms are not well understood, and it seems to be highly unpredictable at best.

Green tea contains a range of polyphenols, including a sub-group called catechins, which clinical trials have focused upon. One study found that participants who drank beverages high in catechins extracted from green tea (690 mg/d) lost significantly more weight and body fat than those who drank beverages low in catechins (22 mg/d).

Green tea also contains naturally occurring caffeine. Caffeine is also present as a separate ingredient; it will increase energy levels and potentially cause a slight increase to the body’s metabolic rate for a few hours after consumption.

However, Evodia reduces the effectiveness of caffeine; whilst this lowers the chances of side effects from the caffeine content, it also reduces the effectiveness of the product.

Green coffee bean is another source of caffeine, but has no current strong clinical research linking it with significant weight loss. The main supporting study was found to be fraudulent and was retracted in 2014.

Tyrosine is an amino acid and so could be useful for consumers who are trying to maximise their muscle gains through muscle-building exercises, as amino acids are the building blocks that form protein. It may also reduce fatigue, but it does not appear to act as an appetite suppressant, as often claimed.

Does Nutrabolics Thermal XTC Have Any Side Effects?

There are numerous ingredients in this supplement that could cause a range of side effects.

Consuming caffeine can cause side effects such as headaches, increased heart rate, increased blood pressure, heart palpitations, increased urination, dehydration, jitteriness, dizziness and insomnia. Green tea can also cause constipation.

Evodia is under-researched, but appears to slow down blood clotting, and so should not be taken in the two weeks before surgery, or whilst recovering from surgery.

Garcinia Cambogia can cause some side effects including nausea, digestive tract discomfort, and headache. Its long term safety is unknown, as clinical studies typically focus upon short term use of up to 12 weeks.

Not suitable for pregnant or breastfeeding women.Not suitable for those under the age of 18. Consult a doctor if you are unsure about the suitability of this or any other diet supplement before purchase. Consult your physician prior to use if you have high blood pressure or heart problems or are taking prescription drugs. Do not consume in the two weeks before any scheduled surgery.

Any Nutrabolics Thermal XTC Reviews From Customers?

There are several customer reviews on, where the product is sold. The positive reviews from have been published on the official Nutrabolics website.

Thermal XTC help me to get in the shape I want and also to maintain it. I recommend This Quality fat burner. It gave me more energy while helping to burn more fat without heart palpitations that you could have with other fat burner products.

Really good product! Great energy throughout the day, no jitters, no tingle, no flush, no heart palpitations – just plain energy and fat burning!

So I got a free sample of these Thermal XTC tablets with one of my orders. I don’t take fat burners on a regular basis, so I can’t really compare these to other similar type products but I was intrigued by the “euphoric energy” tagline on the packaging. Not knowing exactly how these may (or may not) affect me, I opted to take them on a day that I worked from home. I took my first pill with breakfast, as stated on the directions, and then proceeded to head to my computer for my work day. Within about 15-20 minutes, I put my head on my desk for a moment and proceeded to nap HARD for about an hour!! So much for “euphoric energy”! For a supposed thermogenic, I noticed no warming sensation or anything of the sorts in my body. Since I only had a two pill sample, I can’t say how these may do long term… but seeing as how I slept really well after taking one, maybe I would consider them as a night time sleep aide. :\

This is a good clean product. Gives a boost of energy and focus without being jittery or overwhelming.Helps me keep my appetite down a bit, but not a miracle weight loss product. I have tried the tablets twice and the powder form once. I like the tablets much better as the powder if full of aspartame, which I think is unhealthy, and kind of tastes like battery acid. However, the powder form is a bit more potent and packs a bigger punch, but you can always just take two tablets.

Somewhat helpful with keeping up body temperature for workouts, not helpful for weightloss or toning down. Waste of money!!!

So Does Nutrabolics Thermal XTC Work?

Customer reviews for Nutrabolics Thermal XTC tablets are mixed; some love the product, but other consumers found no effects at all. One consumer fell asleep within an hour of taking the product, suggesting that the product is not a very strong stimulant. Customers also report that the powder form of the product is more potent, although it tastes bad. No consumers mention feeling a suppressed appetite.

Garcinia Cambogia has been hugely hyped as a weight loss aid, with various studies looking into many potential benefits including an increased metabolism and appetite suppression. However, many studies in humans show small effects at best, and in one study the placebo was more effective than Garcinia Cambogia at aiding weight loss. Tyrosine is also sometimes promoted as an appetite suppressant, but there is no clinical evidence to support this.

Green tea and caffeine may aid weight loss slightly by increasing thermogenesis and causing a slight increase to the body’s metabolic rate, but their effects are small. Green coffee bean has no current clinical evidence supporting its use as a weight loss aid, other than being another source of caffeine. Evodia appears to reduce the effectiveness of caffeine by breaking it down faster in the body, and the only evidence to suggest that Evodia will increase the metabolism comes from studies in rats.

The part of African mango that is thought to suppress the appetite is a very specific extract, which is not named on the ingredients list, suggesting to us that this African Mango extract is not the most potent extract available for suppressing the appetite.

From looking at the ingredients profile and the customer reviews, we believe that Nutrabolics Thermal XTC is not a strong appetite suppressant. Several of the ingredients used, such as green coffee bean and garcinia cambogia appear to be included because they are popular and over-hyped, rather than actually being effective metabolism boosters or appetite suppressants. The product contains a relatively small amount of caffeine (the amount in three capsules is less than two cups of coffee), and so although it could provide a small boost to the metabolism, we doubt that it will make a huge difference to weight loss.

What About A Guarantee

There is seemingly no money back guarantee for this product. Nutrabolics do not specify what their returns policy is anywhere on their official website; customers should contact the company to find out if they are eligible for returns.

The returns policies of third party distributers may vary.

Watchdog Verdict

The manufacturers of Nutrabolics Thermal XTC make a lot of claims about how their product can aid significant weight loss in numerous different ways. However, we have found that several of the ingredients used in the product have little or no clinical evidence to suggest that the claims made about the product are true. The product will apparently crush the consumer’s appetite, but the appetite suppressing ingredients have very little support. There is slightly more support for the metabolism boosting ingredients used in Nutrabolics Thermal XTC, but some reviewers report feeling very little effect.

The product is not covered by a money back guarantee. The manufacturers fail to even state what their returns policy is on their website, an irresponsible and unprofessional decision that makes it difficult to trust the company.

There are also numerous potential side effects that could be caused by the product.

Overall, we do not recommend Nutrabolics Thermal XTC to our readers.
