Metabolic Plus Amazon Reviews 1

Metabolic Plus Amazon Reviews 2You can find some reviews on the company’s website, but strangely all are dated the 21st of August 2015. No more recent reviews are available and none of these come with pictures to show the results achieved.

We haven’t found any customer reviews on Youtube and there is no activity around Metabolic Plus on social media either.

Dosage – How to take this product

A bottle of Metabolic Plus contains 60 capsules. The recommended dosage of 1 or 2 capsules a day is easy to stick to. However, the label doesn’t state when the doses should be taken. It would be helpful if there were clear instructions to take it before, during or after meal times.


Metabolic Plus is lower priced than other competitor fat burners. Buying the product through the company’s website costs about £16 per bottle, but this seems to be a sale price. The original price is around £33 and it isn’t clear how long the sale is on for.

The company offers free UK delivery when you order through their website.

When you buy the product through other websites, the price may vary.

Where can I buy it?

Metabolic Plus is available through the company’s website as well as on Amazon and Ebay.

Top 3 recommended fat burners


Metabolic Plus fat burner clearly shows the ingredients on the label. The product contains three main ingredients and a couple of supporting ingredients. The main ingredients are Capsicum (800 mg per capsule), Caffeine (120 mg per capsule) and Green Tea Extract (500 mg per capsule).

Metabolic Plus contains a high dose of capsicum, the active ingredient in cayenne pepper extract. Capsicum is thought to act in two ways in our body.

There is research evidence showing its beneficial properties as a natural thermogenic. It increases the body’s metabolism allowing it to burn more fat. It is also thought to be an appetite suppressant. However, there is less research evidence out there proving capsicum’s beneficial property as an appetite suppressant.

Green tea extract and caffeine, the other two main ingredients are also natural thermogenics. They work by increasing the speed at which our body burns fat. There is plenty of evidence out there backing both green tea’s and caffeine’s ability as natural thermogenic fat burners. Due to this, both are common ingredients of a number of fat burner products on the market.

The amount of green tea extract in the product is sufficiently high for this fat burner to be effective. However, the caffeine content is a bit on the low side.

The formula also contains smaller doses of supporting ingredients such as Acetyl-L-carnitine (50 mg per capsule), Vitamin B3 (20 mg per capsule), Black Pepper Extract (5 mg per capsule) and Chromium (100 mcg per capsule).

Potential side effects

No product can claim that it is 100% side effect free and Metabolic Plus is no different.

The main side effects of this product can be caused by the caffeine and capsicum in the formula. If you are sensitive or allergic to any of these ingredients this product may not be for you.

Our Verdict

After reviewing the different aspects of Metabolic Plus, we gave it an above average 4 out of 5 stars.

The ingredients and their quantities are clearly shown on the label and the 3 main ingredients are proven and natural thermogenics. The caffeine content is a bit on the low side, but the green tea extract and the capsicum content is decent. This will limit the results you can achieve with this product.

In addition to this, there are no harmful ingredients in the product like bitter orange peel or synephrine. So there is a lower risk of side effects.

Glucomannan is missing from this product, but it still claims to suppress appetite. It claims to achieve this with the capsicum found in the formula. In research, capsicum has been shown to have some ability to control cravings, but it is not as effective as glucomannan.

The dosage is easy to stick to. However, the instructions on when to take it could be clearer on the label. The low daily dosage also means that you won’t get the constant supply of ingredients throughout the day.

This is a lower priced fat burner when we compare it to other products on the market. However, the mixed reviews on Amazon and the lack of activity on social media and Youtube leave questions about how effective this product really is in achieving fat loss. The daily dosing and the ingredients list could also be improved.
