Thermo Spice Facts

  • Manufactured by Powerman
  • 90 capsules per serving
  • Fat burner and energy booster

Powerman Thermo Spice is a fat burning weight loss supplement manufactured by Powerman. Originally a German company, Powerman has expanded into several other countries, and has dedicated websites for Germany and the UK, amongst others.

The recommended usage is up to three capsules per day, although there are no recommendations of how to take these three capsules. Because the product contains stimulants, we would recommend avoiding use in the evening. Try a smaller dose to start with, taking a capsule before breakfast and perhaps another before lunch or exercise, working up to a higher dose if the consumer feels the need and does not experience side effects.

For customers who have questions for Powerman, clicking on the contact us page on the website takes the customer to a FAQ section. If the customers question cannot be answered in this section, there is a link to contact the company through.

However, customers need to log in or create an account before they can contact Powerman. This makes the entire experience much longer and more complicated than it should be, and puts the customer on the Powerman mailing list, even if they do not order anything from the website.

Powerman Thermo Spice Concerns:

  • Incomplete list of ingredient quantities
  • Only a few reviews available
  • May cause numerous side effects

What Does Powerman Thermo Spice Claim To Do?

According to the official website, Powerman Thermo Spice has the following key benefits:

  • Can support in burning fat during and after exercise
  • Can increase energy levels in preparation for a high intense workout
  • Can support weight loss
  • So What Is Powerman Thermo Spice and What Are The Ingredients?

    There are no ingredient quantities provided on the official website for this product. However, the front of the bottle does state “45 mg caffeine, 50 mg guarana extract, 150 mg citrus aurantium extract” per capsule.

    No information is given on the strength of any extract, such as how much of any key ingredient there is. For example, many companies would state the percentage of catechins or EGCG found in the Green Tea Extract used.

    • Green Tea Extract Powder (17%): Green tea is high in a group of antioxidants called catechins. Studies have suggested that catechins and caffeine both increase energy expenditure by boosting the metabolism temporarily. However, the metabolic increase caused by green tea is limited. One study found that the use of green tea was not enough to counteract weight gain following a very low calorie diet.
    • Bitter Orange Extract (17%): Also known as citrus aurantium, this ingredient contains synephrine. A review of numerous studies concluded that use of synephrine resulted in an increase to the participants resting metabolic rate and energy expenditure, and moderate weight loss was seen in studies lasting over 6 weeks. However, there are some concerns about its safety being under-researched and the numerous side effects that have been associated with it.
    • Magnesium Oxide (14%): Magnesium Oxide can be used to treat heart burn and indigestion, or it can be used as a laxative. However, these treatments usually require much larger doses than are likely used here. Magnesium is also an important electrolyte that is used by the body during exercise, and needs to be replenished for maintaining general health.
    • L-Carnitine Tartrate (16%): Supplementation of this ingredient has been found to improve fat oxidation.Source:
    • Guarana Extract (5.6%): A berry that is naturally high in caffeine, it is often an ingredient in energy drinks and diet pills.
    • Grape Seed Extract (5.6%): Grape seed extract may help to lower cholesterol levels and improve poor circulation. It is also high in anti-oxidants, which may benefit health in general.
    • Caffeine (3.3%): Numerous studies have shown that caffeine boosts energy levels and alertness, as well as mildly boosting the metabolism, causing a small increase in the number of calories used by the body. The effects shown in studies are small, and some studies are inconclusive.
    • L-Ascorbic Acid (3%): More commonly known as Vitamin C.
    • Cayenne Pepper (1.7%): Capsaicin, which is found in Cayenne pepper, is thought by some to play a role in weight loss. Some studies suggest it could suppress the appetite mildly, whilst others suggest that the heat causes a thermogenic reaction in the body, burning more calories for a period of time. However, there are also studies that show cayenne has little or no effect upon weight loss attempts.
    • Taurine (1.1%):Used often in energy drinks, some studies suggest that this amino acid may play a role in athletic performance, meaning that it is only useful for dieters who exercise. There is no link between Taurine and weight loss known at this time.
    • Coenzyme Q10 (0.3%):This coenzyme is found naturally in some foods and can be synthesised in the liver. Cells in the body ‘use it to produce energy your body needs for cell growth and maintenance. It also functions as an antioxidant, which protects the body from damage caused by harmful molecules.’It is also thought to boost energy levels and speed up recovery from exercise.
    • Zinc oxide (0.27%): Zinc is a mineral and electrolyte used by the body. Electrolytes levels are severely lowered during exercise, and so replenishing them is important for general health.

    So What Does All This Mean?

    There are some metabolism boosting and fat burning ingredients in this diet pill, including green tea extract, several sources of caffeine, bitter orange extract, cayenne pepper and L-Carnitine Tartrate. The presence of Magnesium and Zinc make this a good pre-workout supplement choice, as these are two of the electrolytes that are seriously depleted through exercise, needing to be replenished quickly. The ingredients also seem to focus on boosting energy levels, as well as focusing upon fat burning.

    Powerman Thermo Spice does contain Bitter orange extract, which is a stimulant that has been clinically proven to boost the metabolism, but is also linked with a wide range of side effects, as detailed below. The Mayo Clinic recommends avoiding this product due to safety concerns.

    Does Powerman Thermo Spice Have Any Side Effects?

    Powerman Thermo Spice contains both bitter orange extracts and several sources of caffeine.

    Side effects associated with caffeine include headaches, increased urination, jitteriness, dehydration, increased blood pressure, heart palpitations and problems sleeping. Caffeine in turn enhances the effects of Bitter orange extract, which carries its own set of side effects, including increased heart rate and increased blood pressure, heart palpitations, fainting, and even heart attack and stroke in healthy patients. The Mayo clinic advises against the use of Bitter orange extract because of these risks.

    Cayenne Pepper can cause indigestion and stomach ache. Magnesium can be used to treat heartburn, and so this may be counteracted by the magnesium content in Powerman Thermo Spice. However, without knowing the quantities of each ingredient, this is just speculation, and side effects may still occur.


    Caution: Avoid if you are pregnant or breast-feeding. Not suitable for those aged under 18 years.

    Any Powerman Thermo Spice Reviews From Customers?

    There are very few customer reviews for this product, and they are spread over numerous different websites. There is one review on the official website:

    Definitely lost weight using Thermo Spice! I feel like i have more energy when i work out due to the caffeine within the product and now take it every workout. Really good product.

    Back in September 2014, a website called offered 10 free bottles of Powerman Thermo Spice in exchange for honest reviews of the product. The same offer was also promoted on

    Whilst these reviews are intended to be honest, we do feel the need to point out that the people who have written these reviews have not paid for the product, and it is unclear whether they would have chosen Powerman Thermo Spice if they had to pay the full price for the product. Reviewers also do not have to state in their review that they received the product for free.

    From the lack of customer reviews at the time of writing this review, it seems that these reviews in exchange for free products have not been posted yet.

    So Does Powerman Thermo Spice Work?

    No ingredient quantities are provided, which makes establishing how strong this diet pill is incredibly difficult. The official website does provide the percentage value of each ingredient out of the total product, but this is not very helpful at all, considering we do not know the total quantity of the formula in each pill.

    The customer reviews are helpful; although there are very few of them, they are generally very positive, indicating that this product is best used as a pre-workout weight loss capsule that boosts energy levels. Considering that several of the ingredients are electrolytes that are naturally depleted quickly during exercise, the product is even more beneficial when used just before exercise.

    The ingredients list suggests that it does have some weight loss potential, boosting energy levels and the body’s metabolic rate, thanks to several stimulant ingredients. However, some of these ingredients can cause serious side effects, especially bitter orange extract. The Mayo Clinic has advised that dieters avoid the use of Bitter orange extract, because the risk of experiencing these side effects outweighs any potential weight loss benefits.

    Where Can I Buy Powerman Thermo Spice?

    Powerman Thermo Spice can be purchased from a number of different online retailers.

    The official Powerman website sells one bottle of 90 capsules for £19.90, and comes with a free mystery gift. Every week the mystery gift changes, and we were unable to locate any information about what type of items the mystery gift could be. This mystery gift could be a limited time offer.

    Powerman offer next day delivery options if ordering by 9pm, and standard delivery is free on orders over £10.

    Another website, called, also sell Powerman Thermo Spice, with each bottle costing £19.99. The Hut appears to be connected with the Powerman brand, as is mentioned on the about us page of the Powerman website.

    What About A Guarantee

    There is no money back guarantee on this product, but Powerman do give the customer a 14 day returns period. This starts from the day that the goods are received. To obtain a refund, customers need to contact Powerman, cancel their order and arrange to return the product within this period. It appears that returns that arrive with the company after the 14 day period is ok, provided the return was arranged within the initial returns period. Products need to be unopened and unused.

    Watchdog Verdict

    With a lack of in depth reviews of this product, it is difficult to establish what customers in general actually think about Powerman Thermo Spice. It is also difficult to work out the likelihood of potential side effects actually occurring, both due to a lack of information on ingredient quantities and the lack of customer reviews.

    The ingredients list does contain a number of clinically proven weight loss boosting ingredients, but also includes Bitter orange extract, a stimulant which has been the source of numerous side effects. This product is therefore unsuitable for anyone with heart related health problems, including high blood pressure. People in general should also consider avoiding diet pills containing bitter orange extract.

    With ingredients that can cause serious side effects as well as weight loss, and no money back guarantee, we cannot recommend this product to our readers.

    We reject Powerman Thermo Spice as a diet pill.
