What You Need To Know About Activeman Thermolean

Overall, we are not hugely impressed by Activeman Thermolean. The product appears to rely upon caffeine and green tea as its most effective ingredients, and yet these are generally thought to have only a small effect compared to some other diet pill ingredients. The main active ingredient, green coffee bean, has no clinical evidence to support it since the main study promoting it was fraudulent; however, the manufacturers still claim that Activeman Thermolean combines ‘a selection of the best and most researched weight loss ingredients to assist with reducing body fat levels, whilst maintaining lean muscle mass for optimum performance and endurance’.

What Are The Side Effects Of Activeman Thermolean?

There are several ingredients used in Activeman Thermolean that could potentially cause a range of side effects. For a full list, please see the Side Effects tab below.

How Much Does Activeman Thermolean Cost?

Activeman Thermolean is available from the official Bio Synergy website, with a single bottle of 90 capsules costing £29.99 plus delivery.

Our Verdict On Activeman Thermolean

There is no money back guarantee on offer for this product. Despite the product supposedly being manufactured for athletes, it is available for purchase primarily through numerous British Catalogue sellers, and is only featured on one website that actually targets a body building and athletic market.

We do not recommend Activeman Thermolean to our readers. We believe that it is nowhere near as strong or effective at fat burning as the manufacturers would have customers believe.

Activeman Thermolean Review

Activeman Thermolean, and the rest of the Activeman range, are manufactured by Bio Synergy. They are designed specifically for use by men. Consumers are encouraged to follow an ActiVeman or Bio Synergy nutrition plan and workout regime, in order to maximise their results. The product is described as a thermogenic fat burner designed with athletes in mind, making it an ‘ideal sports supplement for endurance and performance athletes’.

How to Take Activeman Thermolean

Take 2 capsules per day with water before food.

The only strong evidence that showed a link between green coffee bean and weight loss was retracted in October 2014. Green Coffee Bean extract is unlikely to contribute to significant weight loss, as there is a lack of relevant and legitimate clinical support. It is a source of caffeine, which will have a mild impact upon weight loss through increasing the body’s metabolic rate for a few hours after consumption. There are several other sources of caffeine in this product as well, such as green tea, and caffeine as a separate ingredient. Green tea also contains catechins, a sub-group of polyphenols that are thought to increase thermogenesis in the body, potentially helping the body to burn a few additional calories per day.

Chromium lowers and stabilises blood sugar levels, which can help to reduce cravings for food.

Activeman Thermolean Concerns:

  • No money back guarantee
  • Main ingredient unproven and ineffective

What Does Activeman Thermolean Claim To Do?

The manufacturers of Activeman Thermolean have provided the following list of the supposed benefits of the product:

  • Powerful thermogenic fat burner designed to get athletes race ready
  • Unique blend of metabolic boosting, fat burning ingredients
  • Noticeable results within one month
  • Ideal sports supplement for endurance and performance athletes
  • Supported by extensive research on fat burning

Does Activeman Thermolean Work?

Customer reviews for this product are mixed, and limited. Consumers have not noted any side effects, but some feel that the product made no difference to their weight loss or energy levels.

The ingredients list includes lots of ingredients that feature naturally occurring caffeine. There is no information on the total caffeine dosage per serving.

The main ingredient is green coffee bean, despite this ingredient having the least clinical support of all of the ingredients used. It is also unclear how a mere 20 mg of green tea can provide more than five times that dose of polyphenols, leading us to suspect that there could be a typo in the supplement information.

Potentially, this diet pill could aid a small amount of weight loss by increasing the metabolism slightly (thanks to the caffeine content) and the green tea content increasing thermogenesis in the body. However, we do not believe that this product is very strong at all, and it is certainly not as strong as advertised by the manufacturers.

What Are The Ingredients of Activeman Thermolean?

The ingredients used in Activeman Thermolean are listed below. The ingredient quantities listed are per serving of 2 capsules.

  • Calcium 125 mg 16% NRV
  • Zinc 10 mg 100 mg NRV
  • Copper 1 mg 100% NRV
  • Chromium 200 mcg 500% RDA: 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.
  • Green Coffee Bean Exract 250 mg(providing chlorogenic acid 125 mg): 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:
  • Green Tea Extract 20 mg (providing polyphenols 108mg): 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.
  • Cinnamon 100 mg: Several studies have found a link between cinnamon and the regulation of blood glucose levels, and it may play a small role in improving insulin sensitivity. In terms of its effects upon weight, this area has been under researched.
  • Alpha Lipoic Acid 60 mg: Appears to suppress the appetite by inhibiting AMPK in the hypothalamus although little research has been conducted in humans at this point. This fatty acid also appears to boost fat burning slightly, although the effects are not as large as the noted suppression of appetite.
  • Choline Bitartrate 100 mg
  • Caffeine 50 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.

Does Activeman Thermolean Have Any Side Effects?

There are several ingredients used in Activeman Thermolean that could potentially cause a range of side effects.

There are two possible sources of caffeine in this product as well as the caffeine used as a separate ingredient, green tea and green coffee bean.

Consumption of caffeine can cause a variety of side effects, including headaches, increased heart rate, increased blood pressure, heart palpitations, increased urination, dehydration, jitteriness, dizziness and insomnia. Green Tea can also cause constipation.

There is an amino acid in Green Coffee Bean called homocysteine that is associated with an increased risk of heart disease.

Chromium can lower blood sugars levels and as such should not be used by diabetics without first consulting their doctor. Low blood sugar levels can lead to light headedness, dizziness and even fainting. Customers who have not eaten for several hours are more likely to experience these side effects.

Cinnamon can cause side effects such as lowered blood sugar, and when taken in large quantities has been associated with worsened liver disease, thanks to a chemical called coumarin.

Contains a source of caffeine. Not recommended for children. Not recommended for pregnant or breastfeeding women. Do not exceed recommended daily dose. Not suitable for vegetarians.

use these daily, great way to burn / strip off a bit of fat, I also find helps digestion for larger meals. really good quality product that uses a few well know natural / herbal ingredients. Great packaging too.

There are also some customer reviews for the product on the Littlewoods and Very websites. These companies are joined, and so the customer reviews are identical.

Only been using this product for 3days but so far down 2lbs. This doesn’t give the same jittery feeling similar products have done, very easy to take and seems to be doing what it says on the box… this rate I will definitely be buying more.

Bought for my husband and didn’t notice much difference.

Too soon to say if these are working however they are easy to take and I have not experienced any side effects so I’m very happy with them for now.
