Reduslim: Does it Work? An Honest Review (+Side Effects)

Are you looking for reliable information about Reduslim, a product often suggested for fat and weight loss?

Is it dangerous? Does it really help in losing weight?

I conducted my investigation, attempting to trace back to the most reliable sources of information.

Happy reading 🙂! Feel free to drop a comment for any questions or sharing experiences.

Summary: Reduslim is probably not harmful to your health. However, it is highly likely that it does not contribute to weight or fat loss.

In what form does Reduslim exist?

Reduslim is most commonly found in the form of capsules or pills.

Sometimes these capsules are also sold with a “sweatshirt” offered, but it has nothing to do with Reduslim.

It is presented as a dietary supplement.

It is not a medication: it does not have marketing authorization in Europe, United-States, Switzerland, Canada, or any other country.

What is the official Reduslim website?

There is no official Reduslim website.

The website reduslim.com does not exist.

The website reduslim.fr exists, but it does not contain specific information in legal notices: it is not clear who owns it. It redirects to a page “Official Reduslim Website,” but again, this page does not contain any legally required information regarding the editorial responsibility of the site and its official owner.

Many sites refer to a so-called official website of Revitive, whose address is fr1.landvnr.com/. But this is a site without the required legal notices, very non-transparent.

Here is what this site indicates:

Several sites also pay Google to appear first in Google results for the keyword Reduslim, such as the site Slimminglabs.com. The latter sells various products and is not the apparent owner of the Reduslim brand.

Is Reduslim effective for weight or fat loss?

On some websites, you can read that taking Reduslim every day is enough to lose 10 to 15kg per month without doing anything else.

This promise is in total contradiction with what we know about how the human body functions and the need to address both complete nutrition and physical activity to lose weight.

However, you might be thinking, “Okay, that’s a bit exaggerated, but maybe it can still help me lose 1 or 2 kg?”

To determine if Reduslim can be effective or not, one must first understand its composition.

Here is its composition as presented on the number 1 site on Google in paid advertising for Reduslim:

On Amazon, the same composition can be found:

What do we know about these substances regarding fat or weight loss?

That’s what I will detail now.

Glucomannan and Weight Loss

Glucomannan is a soluble dietary fiber that theoretically promotes satiety, leading to reduced calorie intake (and potential weight loss). However, this assumes a significant reduction in calorie consumption while maintaining the same level of physical activity!

The latest synthesis of studies on the effectiveness of glucomannan for weight loss in cases of overweight or obesity concludes:

The evidence from available randomized clinical trials does not show that glucomannan intake leads to a statistically significant weight loss.

Onakpoya 2014

For example, here are details from one of these studies (Keithley 2013):

53 obese or overweight individuals were divided into two groups, taking 1.33 grams of glucomannan per day or a placebo for two months—twice the amount found in Reduslim.

Two months later, neither group had lost more weight than the other, and there was no significant difference between the two groups in other factors considered (including side effects).

Cocoa Extract and Weight Loss

In theory, cocoa extract, especially the catechin it contains, may promote weight loss by increasing fat metabolism. However, studies are currently primarily conducted on animals.

The only study conducted on humans shows no superior effect on weight loss or waist circumference with cocoa intake in addition to nutritional advice and physical activity compared to individuals receiving only advice without cocoa intake.

Vitamin B1 (Thiamine), Vitamin B6 (Pyridoxine), and Weight Loss

There is even less data on the effects of vitamins B1 and B6 on weight loss.

Some studies show that individuals with obesity or overweight may be deficient in thiamine (Maguire 2018). However, they do not suggest that taking supplements of this vitamin leads to weight loss!

Here is the only human study assessing the effect of vitamin B6 on weight loss. 42 obese or overweight women for four weeks:

• Consumed 500 kcal per day less than usual;
• Additionally consumed 40 mg/day of vitamin B6 (plus another supplement) for half of them, while the other half took a placebo.

Result? The women taking vitamin B6 did not lose more weight after one month!

Conclusion: Is it reasonable to think that Reduslim helps lose fat or weight?

On some websites, you may read this:

Even if ketosis is a real process where the body burns fat for energy, it does not automatically mean significant weight loss.

Weight loss always depends on the balance between calories consumed and calories expended. Ketosis alone does not guarantee that you will lose weight without making other adjustments to your diet or level of physical activity.

Moreover, there is no evidence that Reduslim significantly activates this state of ketosis.

Conclusion: It is highly likely that Reduslim has no interest in losing weight or fat.

Another point: while many dietary supplements are evaluated in clinical studies, this is not the case for Reduslim as of October 2023. That’s why I went molecule by molecule.

Is There a Danger in Taking Reduslim?

To determine if Reduslim can be dangerous or not, you need to know its composition.

Good news, we just saw it 🙂

Even though there aren’t many studies conducted on people taking these substances, it is reasonable to think that there are no serious and frequent side effects associated with the consumption of these substances by people without particular health problems. This is because such events are not mentioned in the studies.

Here are the conclusions of a research team that looked into the dangers associated with consuming weight management dietary supplements, including those containing cocoa extract or glucomannan:

Weight management supplements containing caffeine, green tea extract, green coffee bean extract, choline, glucomannan, capsaicinoids, and capsinoids are generally safe when taken as directed.

Mah 2022

Are there still contraindications when you have certain diseases or treatments? (Beyond the existing risks of allergies, as with any substance.)

Side Effects and Contraindications of Vitamin B1 (Thiamine) and Vitamin B6 (Pyridoxine)

There are not really any contraindications to taking these vitamins as they are found in everyday food.

There is doubt about whether vitamin B6, when taken in very large quantities, can cause neuropathies (pain and nerve disorders). (Muhamad 2023)

Side Effects and Contraindications of Cocoa Extract

There are no specific contraindications.

Cocoa extract may contain small amounts of caffeine, which can lead to caffeine-related side effects such as nervousness, insomnia, palpitations, etc.

Side Effects and Contraindications of Glucomannan

It is recommended not to take glucomannan if you have a history of swallowing problems or gastrointestinal obstruction.

If glucomannan is not taken with enough water, it can cause bloating, constipation, or other gastrointestinal disorders.

Esophageal or intestinal obstructions can occur if glucomannan is ingested incorrectly.

Where to Find Medical Review on Reduslim?

If I wrote this article, it is precisely because it is very difficult (impossible?) to find a serious and reasoned medical opinion on Reduslim. At least not in the first search engine results.

Some sites like vulgaris-medical.com write articles about Reduslim. While the name of this site may seem serious at first glance, it is not actually run by healthcare professionals.

A retired general practitioner is mentioned on the about page, but there is no last name. It is reasonable to doubt their real existence.

On other sites, you might come across things like this:

If you are looking for a medical opinion on Reduslim, the best option, in my opinion, is to consult your general practitioner. They know your personal situation, medical history, and can provide a more personalized and rigorous response.

Can You Find Reviews on Reduslim on Forums?

Yes, you can find reviews on Amazon, on social media using the hashtag #reduslim, on forums like Doctissimo, in comments on blogs like mine…

The issue with reviews, in my opinion, is that you’ll find just as many negative ones as positive ones. It’s challenging to sort through and determine which ones come from real people.

Additionally, it’s unclear what other actions people took alongside using Reduslim.

Is Reduslim Sold in Pharmacies or Drugstores?

To my knowledge, Reduslim is not sold in regular pharmacies.

However, you can find it on numerous websites labeled as “parapharmacy,” though the term can be ambiguous.

For example, it may be available on the Docmorris/Doctipharma website, one of the main health product sites in the United States.

Is Reduslim a Scam?

My goal with this article is not to conclude that Reduslim is a scam. I believe it’s up to each person to form their own opinion on this matter.

I can share my perspective and how I arrive at it:

1. I observe that sites selling Reduslim make very significant claims about its effectiveness.
2. When I analyze these claims, they do not align with our current knowledge. However, Reduslim does not seem to be harmful to individuals without specific issues, provided it is consumed with enough water.
3. I would not recommend anyone take Reduslim, and I would not choose to take it myself, even for testing, if I were looking to lose weight.
