Fast Burn Extreme Fast Burn Extreme is presented by its manufacturer as a multi-ingredient fat burner, designed for athletes, modern physically active men and women. It is also designed for athletes of all levels. But it could also be used by all kinds of people struggling with excessive fat.

Usually, all fat burners for dryness have formulas designed to limit storage and reduce fat mass. Does Fast Burn Extreme follow the same logic? That’s what we intend to find out with you via our survey. We’ll take a look at the product’s advantages and disadvantages compared with the other fat burners we’ve already examined.

Fast Burn Extreme, a fast fat burner?

Fast Burn Extreme is a multi-component fat burner of natural origin, as confirmed by its manufacturer. Thanks to its content of extracts of Indian nettle, bitter orange, green tea and many other products we’ll discover later, this product is said to promote weight control and stimulate the reduction of fat reserves.

Key Player Limited, based in the United Arab Emirates, is the name of the manufacturer of the product we are currently testing.

  • Weight control and reduction;
  • Blocking of fat storage.

Such promises certainly call for a similarly packed ingredient list, to honor the commitments made by the manufacturer of Fast Burn Extreme.

The ingredients Fast Burn Extreme ingredients and their mechanism of action

Fast Burn Extreme features ingredients which promote weight loss in athletes and users who maintain a relatively active lifestyle. A total of 8 ingredients are available:

Indian nettle extract:

Also known as Coleus forskohlii , nettle is a wild herb traditionally used in India for the treatment of heart failure, hypertension and urinary inflammation, as well as for weight loss.

Mechanism of action in brief: Nettle increases the production of cAMP, an organic compound whose role is to accelerate fat combustion, thus inducing weight loss.

Bitter orange extract:

Scientific name Citrus aurantium, a tree native to southeast Asia, also found in Egypt, Syria and other parts of Arabia.
Composed of flavonoids, synephrine, pectin, healing and antibacterial essential oils, limonenes and coumarins, vitamin C, carotenes and tyramines.

Mechanism of action in brief: This ingredient supports the functions of your digestive system by suppressing your appetite. This is achieved by increasing fat metabolism and stabilizing blood glucose levels.

Green tea extract:

Scientifically known as Camelia Sinensis, green tea is a well-known plant whose name is associated with many benefits. It’s a source of over 400 chemical compounds, vitamins and minerals. But where green tea really shines is in its vast array of antioxidants, including Epigallocatechin gallate.

Mechanism of action in brief: Green tea extract is a powerful antioxidant essential for protecting the body from free radicals, stimulating fatty acid oxidation and promoting body thermogenesis. Several researchers have demonstrated its action in natural fat loss.

Paprika extract:

Capsicum annuum is the Latin name for all varieties of pepper except black pepper. All peppers contain a certain amount of capsaicin. Researchers found that taking 2.5 milligrams of capsaicinoids reduced the total number of calories consumed in a meal. As a result, scientists concluded that including capsaicin in your diet could help with weight management, as it would reduce overall calorie intake.

Mechanism of action in brief: Paprika extract supports digestive system functions by activating the process of burning fat reserves and protecting your stomach.

Garcinia cambogia extract:

A subtropical plant found in Southeast Asia, India and Africa. Its role in weight control is well known, as it is both a fat burner and an appetite suppressant. Its main ingredient, HCA (Hydroxycitric Acid), is believed to be the source of these virtues.

Mechanism of action in brief: it’s highly effective at suppressing appetite, blocking fat storage and stabilizing blood sugar levels.


Classified as a central nervous system stimulant by acting on neurotransmitters, caffeine is a very popular substance worldwide. It occurs naturally in over 60 substances, including coffee, tea, guarana, yerba maté, cola nuts and cocoa.
This substance increases alertness and cognition, general tone and physical performance, and boosts resting metabolism.

Mechanism of action in brief: Thanks to its appetite-suppressant, diuretic and fat-burning properties, caffeine is present in many slimming products. Regular caffeine consumption will enable you to exercise for longer while achieving the best possible results.


A component already present in the human body in minute traces. The commercialized form of chromium is chromium picolinate. Chromium plays a vital role in the metabolism of sugars, as it helps insulin to regulate blood glucose, thus preventing fat storage. It is recommended for weight loss and muscle gain in athletes.

Mechanism of action in brief : Chromium is said to help solve the snacking problem. When sugar has been stabilized, it can also suppress your appetite. It also supports macronutrient metabolism.

Vitamin B6:

This is a water-soluble vitamin known as “essential”. Our bodies can neither manufacture nor store it, so we must draw it daily from food in the form of pyridoxine, pyridoxal and pyridoxamine. Vitamin B6 is found in offal, fish, brewer’s yeast, meat, wheat germ, whole grains and legumes, bananas and beans. Used to prevent cardiovascular disease, the recommended daily intake for adults is 100 mg.

Mechanism of action in brief: Vitamin B6 ensures that the body has an adequate energy metabolism process capable of maintaining internal balance, while regulating the functioning of the endocrine system.
