Looking at some diet products can be painful, especially if there’s no backing for the formula. Let’s find out if glucomannan is in this group. We’ve heard a lot in the weight-loss community about this fiber supplement, so we conducted one of our detailed reviews, looking at the ingredients, negative side effects, scientific research, and the quality of their customer service team. We also read hundreds of commends and reviews from readers online. We then summarized and condensed to give you the info you need.
What You Need to Know
To begin with, glucomannan is a dietary fiber that comes from the konjac root. It is explained by manufacturers as an all-natural way to lose weight. It works to eliminate fats by bypassing the digestive process and reducing the caloric impact on your body. Glucomannan is primarily sold in tablet form, which means it can be consumed anywhere.
The product has been around for several years, but because it is produced by multiple companies it is difficult to find customer service, an official website, scientific research or data behind how well it works. The all natural ingredients, low cost, availability and convenience make this sound like an intriguing fiber supplement, but read on…
Lack of Results – “No Changes in Weight?”
One of the first things that concerns us about glucomannan ingredients is that it may not work. In a recent study, just 5 percent of obese patients taking glucomannan lost more than 5 pounds over an eight-week period. “At $9 per bottle, glucomannan seems like a steal,” said our Research Editor. “But the minimal results and harmful side effects make even that too much for this fiber supplement.
“Results were minimal, and way too slow, I guess you get what you pay for” said one user.
“I lost 2 pounds over an 8 week period, which isn’t enough to justify a monthly purchase,” explains another.

Harmful Side Effects – “A Concern”
Something else we noticed in multiple reviews and on medical websites was the potential for harmful side effects when taking glucomannan. Because it partially bypasses the digestive system, it can nullify the effects of different medications. It can also have adverse issues for diabetics by mitigating the results of insulin intake.
“At $9 a bottle, I was excited to try glucomannan, but once I looked at the side effects and health concerns, I threw my bottle away,” said one would-be user.
Another claimed “This fiber supplement rendered my heart medication useless. I had to stop taking it immediately to avoid further complications.”
Our studies of various health and diet products has shown that when there is something abnormally difficult or troublesome about a particular supplement or routine (cost, side effects, slow results, pain/difficulty of an exercise routine, etc.) users are more likely to give up and long-term success is rare. If glucomannan really does cause adverse reactions, this could be an issue for those attempting to lose weight.
If you are interested in using glucomannan to lose weight, we recommend that you do so without taking any other medications. If this is taken by itself, with no other medications, it may not cause negative side effects.
The Science – “Legitimate?”
Glucomannan has a scientific sounding name, but there’s very little data to be found. There are no studies proving the effectiveness of this fiber and although it’s significantly cheaper than comparable products, there’s no data proving that it matches up to proven formulas. At DietSpotlight, we emphasize science when it comes to weight-loss and when there is no proof for a particular supplement, we find that troublesome.
The Bottom Line – Does Glucomannan Work?
Ladies and gentlemen, what’s the final word on glucomannan? There was a lot to like about this one initially, like the affordability, convenience and availability. There were also a few positive comments online, proving that some people did find it possible to steadily lose weight. Unfortunately, there were a few major concerns for us and that means we’re hesitant recommending this as an effective weight-loss supplement. Glucomannan’s lack of results and science behind the product’s claims make this one that we cannot recommend. We also have some concern about the lack of a website or customer service center.
If you’re still interested in losing weight, we suggest you find a supplement that is affordable, but that also delivers on its weight-loss claims without the negative side effects. To do this, look for a product that has scientific research and clinical studies that back it up.
Among the best products we’ve seen in 2015 is one called Leptigen. The makers have their own proprietary formula of just four ingredients that have all been shown to help boost weight-loss by promoting fat burning and sparking your metabolism. This supplement does have significant scientific papers and clinical studies proving that it works. There are also many reviews online from satisfied users that have seen great results without unintended side effects.
The makers of Leptigen are so sure that their product will help you lose weight that they’re offering a Special Trial Offer. It’s always encouraging to see a company stand behind their supplement.
