What other people say about this product

I’ve looked for customer reviews of Thermakor on the various websites to see what most people say about it. I’ve found mixed reviews on different supplement review websites most of them giving it an average rating. Recent reviews from customers who purchased this product on Amazon were a lot less favourable. Some reviewers saw no change in weight loss and some experienced side effects with the most recent reviewer only giving it 1 out of 5 possible stars. Amazon Thermakor review I haven’t found any customer testimonials on Youtube and there’s not a lot of activity on social media either around this product which raises some questions as I would have expected to find some with a product that has been around for more than 2 years.

Dosage – How to take Thermakor fat burner

The dosage of this fat burner is pretty easy to stick to. One bottle of Thermakor fat burner contains 60 capsules. As per the manufacturer, the recommended dosage is 2 capsules per day. One in the morning before breakfast and one later in the day before the evening meal.


Thermakor fat burner is a premium priced product. The cost of Thermakor will vary depending on where you’re buying it from. On the Kor Nutrition website, there are different deals. 1 month supply / 1 bottle – $59 (roughly £40) plus shipping 2 months supply / 2 bottles – $198 (roughly £70) plus shipping 3 months supply / 3 bottles – $117 (roughly £80) plus shipping

Where can I buy it?

You can buy Thermakor through the company’s website as well as other online supplement retailer sites and even from Amazon. Reading the shipping options on their website, it sounds like that they only ship from the USA. In the FAQ section of their website, they advise an up to 2-3 week delivery time for orders outside of the USA. In addition to this, you may need to pay import duty depending on the country you want to ship the product to.

Top 3 recommended fat burners


When it comes to the ingredients of Thermakor, it is not entirely clear what this product contains and in what quantities. On Kor Nutrition’s website, there are nine ingredients listed with quantities for each of them. So far so good. However, when you look at the label on the bottle there seems to be a lot of additional ingredients other than the nine on the supplement company’s website. In addition to this, there are no exact quantities displayed on the bottle either. The website shouts about the all natural ingredients in this product which is very promising, but not showing the quantities clearly on the bottle or not listing the full list of ingredients on the website gives me cause for concern. There are nine ingredients on the Kor Nutrition website. Green Tea (300mg per 2 capsules), Green Coffee Bean Extract (300mg per 2 capsules), Razberi-K (AKA Raspberry Ketone) (200mg per 2 capsules), Caffeine Anhydrous (150mg per 2 capsules), Salicin (125mg per 2 capsules), Garcinia Cambogia (100mg per 2 capsules), Synephrine (50mg per 2 capsules), Forslean (50mg per 2 capsules) and Hordenine (25mg per 2 capsules).

Green Tea

The first main ingredient based on the amount contained in the product is green tea. Thermakor fat burner contains 300mg of this natural thermogenic which is about 5 – 6 cups of tea. There is plenty of research out there backing the effectiveness of green tea as a natural fat burner. It contains polyphenols that increase the body’s metabolism and therefore increasing the rate at which the body turns food into energy.

Green Coffee Bean Extract

Green Coffee Bean Extract, the second main ingredient of Thermakor fat burner contains a chemical called chlorogenic acid that has been linked to a number of different health benefits one of which is weight loss. Some studies conducted on humans have shown reduced absorption of carbohydrates from the digestive tract and reduced weight. Studies conducted on animals suggested that chlorogenic acid can reduce body weight by reducing the amount of fat absorbed from the diet and by improving the function of the fat burning hormones.

Raspberry Ketones

Razberi-K, also known as Raspberry Ketones became increasingly popular as a fat burner ingredient in recent years. It is a natural compound that gives raspberries their distinctive aroma. Some research conducted on rats has shown promising signs of raspberry ketones helping the body break down fat. These are great initial results. However, to date, there have been no human studies conducted that could support the claims made by supplement manufacturers that raspberry ketones are the new miracle fat burners. Also, due to the lack of human research, the potential side effects of raspberry ketones in humans are still unknown.


Caffeine Anhydrous, the fourth main ingredient of this product is another natural fat burner that helps to cut fat through thermogenesis. It increases catecholamine levels in the blood that are responsible for mobilising the fat stores enabling the body to burn more fat. Caffeine also gives the body an energy boost you need before workouts so you can go harder in the gym. Caffeine is found in most fat burners out there. Thermakor contains 150mg of caffeine per serving which is on the low side compared to our top recommended products. In addition to these main ingredients, Thermakor fat burner also contains smaller doses of Salicin (125mg per 2 capsules), Garcinia Cambogia (100mg per 2 capsules), Synephrine (50mg per 2 capsules), Forslean (50mg per 2 capsules) and Hordenine (25mg per 2 capsules).


Synephrine, in particular, is a compound of bitter orange. A compound which has similar effects to that of ephedra, an ingredient previously banned by the FDA due to the related health risks. Some studies have found evidence that synephrine increases metabolic rate in individuals and can, therefore, aid weight loss. Despite some supportive research, there is a lack of evidence that synephrine is effective in maintaining weight loss. Synephrine has been linked to potentially serious side effects. However, the dose in this formula is quite low. The list of ingredients as extensive as it is doesn’t stop here. If you look at the label of this product, there are additional ingredients that are not included on the company’s website and on the label, there are no quantities displayed either. The product seems to contain ingredients such as yohimbe extract which can cause side effects like altering your blood pressure, but the actual quantity is not advised either on the label or on the company’s website.

Potential side effects of Thermakor fat burner

There are potential side effects associated with a number of ingredients in this product. Due to its aspirin-like properties salicin can cause issues for people who have an intolerance or are allergic to aspirin. Furthermore, the Yohimbe in this product can have an adverse effect on people’s blood pressure. Caffeine can also cause potential side effects for those intolerant or allergic to it. Last but not least, due to the synephrine content of this product, it has potential side effects such as increased blood pressure and elevated heart rate. These can be potentially dangerous when combining with other stimulants like caffeine or green tea, both of which are present in this product.

Final Verdict on Thermakor fat burner

Based on the above, I would give this product a lower than average rating of 1.5 out of 5 stars. It contains some proven thermogenics like green tea and caffeine. However, the dose of caffeine per daily serving is still on the low side. It also has a lot of other ingredients that have no sufficient evidence behind their effectiveness. In addition to this, it contains synephrine which may have potentially dangerous side effects. What’s more, the ingredients list on the bottle doesn’t actually state amounts which is concerning to me. The lack of recent customer testimonials and the lack of this product’s appearance on social media also raises questions around Thermakor fat burner’s effectiveness. The 30-day money back guarantee stated on the company’s website is a positive for this product. However, as they only seem to ship from the USA, if you are ordering outside of America, you may be in for a long wait. Not only that, but it may be problematic returning the product if you want to get your money back. In the terms and conditions of the company’s website, they state “In order to obtain your refund for an order you must send in the product within 30 days of your initial order date.” which means that you may not be within this window if it takes 3 weeks just to receive the initial order. For the above reasons, I would not recommend buying this product. There are better options out there for the same price.
