Biocyte Blockeur Forte, the fat killer

boite-biocyte-blockeur-forteWhen we’re on a diet, we sometimes break down and eat a meal rich in fats and sugars. And when we’re not on a diet, well, we also sometimes have a good meal, at a restaurant with friends or with family on a special occasion.

To help us compensate for these deviations, which can either slow down our weight loss or cause us to gain weight, fat catchers are the ideal supplements. We’ve put BIOCYTE BLOCKEUR FORTE to the test to see how well it captures the fat from our excesses.

Presentation and promises of Biocyte Blockeur Forte

As we’ve said, Biocyte Blockeur Forte is a fat catcher. It is designed for people who want to lose a few kilos, but also for those who want to compensate for an overly rich diet or better control their appetite.

Biocyte Blockeur Forte acts in 3 ways:

  • Capture fat from the diet and encourage its elimination;
  • Accelerate weight loss;
  • Refining the waistline.

This supplement is ideal for meals eaten on the run, which are often unbalanced, or meals that are too rich.

The manufacturer recommends taking 2 to 3 capsules, twice a day, if your BMI is 25 or above.

For weight maintenance, 1 to 2 capsules twice a day will suffice.

The manufacturer of Biocyte Blockeur Forte

We are dealing with a laboratory specialized in nutricosmetics and cosmetics, namely Biocyte, created in 2006.

Biocyte is currently run by 2 experts in the field of dietary supplements, namely the former founder of Forte Pharma laboratories, and a pharmaceutical industry expert who worked for Forte Pharma and Arkopharma.

All products comply with current regulations on manufacturing processes, ingredient selection and quality control.

In short, a manufacturer you can trust!

Biocyte Blockeur Forte, ingredients

Each Biocyte Blockeur Forte capsule contains 500mg of vegetable chitosan extracted from the mycelium of aspergillus niger.

We have already published an article on chitosan, HERE.

Nevertheless, we’re going to talk a little about this ingredient.

Chitosan is composed of D-glucosamine and N-acetyl-D-glucosamine, and is produced, at least in the case of plant chitosan, from chitin found in the walls of certain fungi.

Once in the stomach, chitosan forms a kind of gel, which has an essential advantage:
In the stomach, chitosan gel binds with lipids. In fact, it has the capacity to retain approximately 15 times its weight in fat! This chitosan/fat substance cannot be metabolized, i.e. assimilated, by the body.

It is therefore simply eliminated through natural channels, thereby reducing the amount of fat absorbed by the body.

But in reality, things aren’t quite so simple. As chitosan is only soluble in a medium with a pH below 2, it is only effective in certain, very limited, parts of the digestive system.

It is for this reason that this ingredient acts on fats brought in by meals, and not on fats already stored by the body.

Chitosan therefore limits fat intake, rather than promoting the combustion of stored fat. This is in line with the promise made by Biocyte Blockeur Forte.

It also reduces cholesterol levels, promotes intestinal transit and detoxifies the body of heavy metals.

On the other hand, and for the sake of completeness, we feel it would be useful to talk about this ingredient’s limitations.

In fact, chitosan’s absorption capacity depends on the type of fat ingested. To illustrate this limitation, we refer to a study which compared the absorption of olive oil to ghee (Indian butter).

The second limitation is that chitosan is not soluble in a medium with a pH below 2.

What science has to say about Biocyte Blockeur Forte

Let’s take a closer look at the scientific data on chitosan.

A 2007 meta-analysis attempted to determine the role of chitosan on overweight and obesity.

Having reviewed 15 trials and no fewer than 1219 participants, the group of researchers behind this study concluded that chitosan is more effective than placebo in the short-term treatment of overweight and obesity.

These same researchers questioned the majority of trials carried out to date.

They also argued that, in view of the results obtained from high-quality trials, chitosan’s effect on body weight is minimal and unlikely to be of clinical significance. To be continued!

(Source : NCBI. Clinical Trials Research Unit, University of Auckland, Private Bag 92019, Auckland, New Zealand. Jull AB, Ni Mhurchu C, Bennett DA, Dunshea-Mooij CA, Rodgers A. Cochrane Database Syst Rev. 2008 Jul 16;(3):CD003892. doi: 10.1002/14651858. CD003892. pub3).

Of particular note is a study carried out on an experimental model which attempted to determine the interaction between chitosan and oil in the stomach and under duodenal digestive chemical conditions.

The researchers started from the widespread idea that chitosan has an effect on the absorption of dietary lipids, but that scientific knowledge of this mechanism remains insufficient.

This study showed that chitosan interacts well with oil. Its absorption in the duodenum would thus be reduced, and its elimination improved.

Side effects and contraindications

In the first few days of use, chitosan may cause gas, bloating, diarrhea or constipation in the most sensitive individuals.

However, these effects are not systematic, and mainly occur when there is an overdose.

On the other hand, many warnings have been issued about the risk of choking associated with the use of chitosan in its raw state. With the advent of pill and capsule packaging, this risk is no longer an issue.

Testimonials from Biocyte Blockeur Forte users

Of all the people who have tested Biocyte Blockeur Forte, the vast majority are satisfied with the results.

Consumers judged this fat catcher to be effective, delivering results from the very first week of use.

A close look at these testimonials shows that Biocyte Blockeur Forte is a very positive product.

    Good evening,
    I first ordered a box of Phen 375 capsules and considering the promotions the site was sending me, especially for “me black friday”, I ordered more and I’m disappointed. It’s true that I had “set out” in the spirit of following a diet at the same time (I was really motivated!!) and in fact I’m very disappointed; many customers spoke of a “booster, energizing” effect; for my part I felt absolutely nothing. On the other hand, the appetite suppressant effect that many customers were talking about (often as a priority); as far as I’m concerned, I felt absolutely nothing.

    I’m very disappointed, not with your site, which I find remarkable, but with the results I’d hoped for. Maybe I’m “not made” like everyone else!!!!!!!!!!!!!

    Could you please answer me? Thank you very much.

      Hi Yveline,
      I’m sorry to hear that this product didn’t work for you. Alas, it sometimes happens that a product, even a priori effective, does not work as expected with certain people. But that in no way means that the problem lies with you. On the contrary, it’s the product that hasn’t worked. So don’t give up! If you’ve come to the conclusion that slimming products won’t work for you, too bad! Try physical activity or a dietary adjustment. Otherwise, if you’ve only tried this product, try another, but as we advise our readers, always start with one bottle, continue if it works and stop if it doesn’t. Good luck Yveline!
