Ingredients of Raspberry Ketone Formule extra forte

Raspberry Ketone Formule Extra Forte is composed of :

1. Raspberry extract (1250mg) with Raspberry Ketone (69mg):

We’ve written a full article on raspberry ketone, which can be consulted HERE.

But we’ll just summarize the main properties of this ingredient.

A priori, raspberry ketone acts on adrenalin, increasing blood levels, which boosts metabolism and fat burning.

Raspberry ketone is also said to raise levels of adiponectin, another hormone which, in sufficient quantities, inhibits fat storage.

Finally, raspberry ketone helps to activate the breakdown and elimination of fats, via lipases, the enzymes responsible for breaking down lipids.

2. Green Coffee extract 20:1 (500mg) with 20% chlorogenic acid (25mg):

Here too, we dedicated an entire article to the virtues of green coffee, to be read HERE.

But let’s talk briefly about the benefits of this ingredient.

Green coffee contains 2 active substances that play a very interesting role in weight loss: caffeine and chlorogenic acid.

Caffeine activates the metabolism, increasing thermogenesis and lipolysis. It also improves alertness, concentration and energy levels.

As for chlorogenic acid, it helps regulate blood sugar levels, which in turn helps control food intake, notably by reducing cravings for sugar.

3. Garcinia Cambogia (50mg):

Garcinia has been the subject of a great deal of research, which we’ll cover in the next chapter.

The fact remains that it is thought to have slimming virtues, thanks to its action on serotonin, a hormone involved in regulating appetite, stimulating fat breakdown and elimination, and improving carbohydrate metabolism.

4. Cayenne pepper (50mg):

Capsaicin is the active substance that gives cayenne pepper its properties.

Capsaicin acts as a stimulator of 2 important weight-loss hormones: adrenalin and noradrenalin.

Adrenalin helps control appetite through its appetite-suppressant effect, while noradrenalin helps burn sugars and fats stored in the body.

Finally, cayenne increases metabolism and energy expenditure, which in turn promotes fat loss.

5. Green Tea 22:5:1 (25mg) 95% of which are polyphenols:

Do we still need to explain the benefits of green tea for weight loss?

To summarize its benefits, we can say that green tea contains theanine and catechins, which have multiple properties, including: antioxidant, relaxing, appetite-regulating, metabolism-boosting and mood-enhancing, thermogenesis-activating, intra-visceral fat-reducing.

A versatile ingredient that has been officially recognized by science for its slimming virtues.

6. Cocoa (12.5mg):

Cocoa has multiple health benefits.

It acts as a powerful stimulant, providing the body with a healthy dose of energy.

It fights stress and gloom thanks to one of its components, theobromine, and has antioxidant properties.

It is also said to have fat-burning properties.

7. Zinc (5mg):

Zinc activates the production of leptin, a hormone that plays a role in the sensation of satiety, but also has a role in normalizing blood sugar levels.

Raspberry Ketone Extra Strength Formula and science

What do scientific studies say about the main components of Raspberry Ketone Formule extra forte?

In a study on green coffee, researchers evaluated the effects of chlorogenic acid on glucose absorption and body mass in overweight subjects.

In this study, some participants consumed 440 to 495mg of chlorogenic acid per day for 12 weeks, while others took a placebo.

The results showed a 6.9% reduction in glucose absorption in those taking chlorogenic acid, compared with the control group.

What’s more, these same people saw an average weight loss of 5.4kg, compared with just 1.7kg for the placebo group.

(Source: NCBI. ETC Research and Development, Oslo, Norway. Thom E. J Int Med Res. 2007 Nov-Dec;35(6):900-8).

As for raspberry ketone, although some studies seem to show that it represents a potential stimulator of lipolysis, research on primary adipocytes is inconclusive.

Raspberry ketone does, however, enhance norepinephrine-induced lipolysis in primary adipocytes, which is encouraging.

Further studies, this time in vivo, are needed to validate the fat-burning virtues of raspberry ketone.

Finally, a very recent meta-analysis confirms that capsaicin causes an increase in metabolism, but may also promote better appetite control and optimization of different metabolisms.
