How to Take Thermo-Extreme

Because the product contains caffeine and other stimulants, we would recommend making sure the last dose is not taken late in the evening, as it could affect sleeping patterns. The instructions provided above are open to interpretation, so we would suggest taking a dose before breakfast, before lunch and then only taking a third dose in the late afternoon or before the evening meal if they feel it is necessary. Consumers could also start with a smaller dose, working up to three or four capsules per day as they assess their tolerance to the product.

So What Is Thermo-Extreme and What Are The Ingredients For Thermo-Extreme?
Thermo-Extreme has a huge list of ingredients, but unfortunately no ingredient quantities are provided.
- Citrus Aurantium Herb Powder: Also known as Bitter Orange extract, 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.
- Green Tea Extract (95% Polyphenols):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.
- White Kidney Bean Extract (4:1): One study in humans showed that participants who consumed white kidney bean extract, in addition to being on a multi-component weight loss programs (diet, exercise and behavioural intervention) lost more weight when compared to those who just followed the multi-component diet. However, a large amount of white kidney bean was consumed per day in the study, with participants consuming 2000 mg over the course of each day. It is unclear how much is in each capsule of Thermo Extreme, but it is unlikely to match this amount, considering the number of other ingredients.
- L Tyrosine: An amino acid that is a building block of protein, this ingredient is found naturally in many foods including meat and dairy products. Some people use it as an appetite suppressant, but there is little 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.
- Caffeine: 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.
- Siberian Ginseng (25:1): The Natural Medicine Journal has stated that ‘there is currently little clinical evidence on the use of Siberian ginseng… …to treat any medical condition in humans’, with mixed results from clinical trials and any beneficial effects declining after 8 weeks of use. Claims made about Siberian Ginseng include that it improves athletic performance, can treat insomnia, and is an adaptogen, supposedly strengthening the body and increasing resistance to stress and illnesses.
- Chocamine:Chocamine is a patented cocoa based ingredient for improving ‘cognitive function, mood and energy’. Some people believe that cocoa extracts can help to boost the metabolism, but there is little clinical evidence to suggest it can make a significant impact to weight loss.
- Bladderwrack (4:1):This sea vegetable is a concentrated source of minerals, including iodine, potassium, magnesium, calcium, and iron. It is well known that iodine assists in the production of thyroid hormones, which are necessary for maintaining healthy metabolism in all cells of the body. If a person has no thyroid problems and does not have an iodine deficiency, this ingredient will do little to boost weight loss attempts.
- L Theanine: This amino acid is found in green tea, and may play a small role in weight loss, as well as increasing feelings of relaxation. It may also reduce the negative side effects of caffeine, although there is seemingly no clinical evidence to support this claim.
- Raspberry Ketones: Raspberry ketone is the part of a raspberry (and other fruits) that provides the distinctive smell of raspberries. In general, the raspberry ketone used in diet pills is lab- synthesized. Whilst there is a small amount of evidence that raspberry ketone can cause weight loss in rats, there have never been any human trials on the potential weight loss effects of raspberry ketone. The safety of using such large quantities of raspberry ketone has also never been fully researched.
- Cayenne Powder: Capsaicin is found in Cayenne pepper and 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.
- Pyridoxine HCl: This is a form of vitamin B6. Vitamin B6 has several important functions in the body, including ‘allowing the body to use and store energy from protein and carbohydrates in food’. Whilst taking excess amounts of vitamin B6 will not infinitely improve this ability, a deficiency could make it more difficult to lose weight.
- Black Pepper Extract (95% Piperine): Black pepper extract is used for increasing the bioavailability of nutritional compounds. In other words, it increases the amounts of nutrients that are absorbed into the body in the digestive tract. It may also increase the absorption of various drugs, which may lead to potential side effects. Bioperine is the most common brand of this extract.
- Chromium Picolinate: This is used primarily to lower fasting blood sugar levels and to lower insulin levels in people who have type 2 diabetes. In terms of its potential effect upon weight loss, it is possible that taking chromium picolinate by mouth for 2 to 3 months might produce a small weight loss of about 1.1 kg. Obviously this is an incredibly small amount of weight loss, but studies are still inconclusive.
- Vitamin B12: Vitamin B12 is naturally present in many foods, primarily meat, fish and dairy products. It has several roles, including aiding in releasing energy from consumed food, and keeping the nervous system healthy. It may be that a deficiency hinders weight loss, but taking excess amounts could be, according to the NHS, potentially harmful.
So What Does All This Mean?
With a huge variety of ingredients in Thermo-Extreme, it appears that this diet pill attempts to boost weight loss in a variety of ways. However, without knowing any ingredient quantities, it is not possible to establish how strong this product is, or to compare it to any relevant clinical trials of the individual ingredients.
There are lots of ingredients in Thermo-Extreme that have been associated with boosting the metabolism and increasing the speed of weight loss, including caffeine, cayenne and green tea extracts. White Kidney Bean Extract is thought to block the absorption of carbohydrates, stabilising blood sugar levels and reducing the number of calories absorbed from meals.
Chromium has some evidence to suggest it minimally affects weight loss in the long term. B vitamins are usually found in adequate quantities in a balanced daily diet, but many companies include them anyway in their products, as a deficiency can hinder weight loss attempts. There is little or no evidence to suggest that over-supplementing these vitamins will boost weight loss attempts.
There are several ingredients that may affect weight loss in theory, but there is a lack of clinical evidence to prove these claims. Raspberry ketone is a popular ingredient but the clinical evidence in humans is somewhat lacking. Bladderwack contains iodine, and so could boost weight loss for those who have an iodine deficiency. However there is no evidence it causes weight loss in the general population.
Does Thermo-Extreme Have Any Side Effects?
The official website does not make any mention of potential side effects that could occur from the use of Thermo-Extreme. However, this does not mean that the product is necessarily side effect free.
Thermo-Extreme contains both caffeine and citrus aurantium, which are stimulants that can cause a range of side effects. Side effects of caffeine include headaches, jitteriness and shaking, increased blood pressure, increased heart rate, heart palpitations, increased urination, dehydration and insomnia.
Caffeine can also boost the effects of citrus aurantium, another ingredient in this diet pill. Citrus aurantium has been known to cause 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 stomach aches, indigestion, heart burn and changes in bowel movements, although the tolerance for this ingredient varies hugely between individuals. It can also cause excess sweating, a physical sign that the body is experiencing an increased thermogenic output.
Not suitable for anyone under 18, pregnant or breastfeeding women, anyone with hypertension (high blood pressure), heart disease, or people who have sleep problems.
Any Thermo-Extreme Reviews From Customers?
There are numerous customer reviews of Thermo-Extreme on the official website. The way the review system is set up means that only a few of the most recent reviews can be read, but the ratings of all the reviews can be seen. Of the 119 reviews on the website, the majority are 4 and 5 star reviews, with only nine being 2 or 3 stars, and no ratings of 1 star.
Customers are in general very happy with the product, reporting noticeable results after only a few weeks, increased energy levels whilst exercising, and minimal side effects. Side effects reported include increased sweating, increased heart rate during exercise and occasional nausea when taking the product on an empty stomach. Some customers complain about the taste of the pill, and unpleasant ‘pill flavoured burps’.
I’ve used Thermo Extreme a couple of times when doing cardio and it does help, but the base should be hard training and clean eating of course. I cannot say if it provides you extra energy, I did seen a slightly definition after start using it, but would need more time to have a clear opinion on its usefulness. It does worth a try if you’re trying to have more definition and only dieting it’s not enough.
I have been using these now for just over a week. I have been taking them pre-workout and I have definitely noticed a difference! My stubborn stomach fat seems to be disappearing! … These tablets have given me that extra kick I need! Increased energy levels and overall boost in endurance. I am managing to use weights I never used to be able to and work at such a high intensity. They make you sweat a lot and I did notice I was very talkative on them! No nasty side effects at all and would 110% recommend for those who are looking for that extra boost in the gym to aid weight loss!
So Does Thermo-Extreme Work?
It appears that when used as a pre-workout supplement on training days, and spaced throughout the day for the rest of the week, this product does aid weight loss. The ingredients list is filled with various ingredients that boost the metabolism, along with some other ingredients with more contested properties and less clinical evidence.
Customer reviews support the idea that this product does help to boost weight loss, with consumers reporting increased weight loss, reduced waist measurements and a clear thermogenic effect, felt through increased sweating and energy.
Where Can I Buy Thermo-Extreme?
Thermo-Extreme can be purchased from myprotein, which is the official website of the manufacturer. Each bottle of 120 capsules costs £15.10, reduced from £20.99. Considering that this number of capsules will last the user for 30-40 days, depending upon the dose used, this is a rather low price for a diet pill.
What About A Guarantee
There is no money back guarantee on Thermo-Extreme but there is a 14 day returns period that starts on the date the item is received. Returned items must be in their original condition, sealed and unused.
Whilst many of the customers who have used this product are happy with Thermo-Extreme, we have still found numerous problems with the product. Often when consumers rate products, side effects are ignored if they lost weight. Customers have reported various side effects, and the ingredients profile suggests that more serious side effects could occur in some cases.
There is no money back guarantee for the product, and no ingredient quantities are provided. The company even fails to describe to the customer how the product works, what can be expected from the pills, and any potential side effects. With this lack of clarity from the manufacturer, we cannot approve this product, even though it is affordable and well-received by customers.
We reject Thermo-Extreme.
