There are certain natural ingredients that are particularly helpful for weight loss. Glucomannan supplements have been getting a lot of attention lately because glucomannan appears to be one of those ingredients that accelerates weight loss for most people.

But because glucomannan supplements are getting more and more popular, that means that more and more manufacturers are producing them. As a result, it can be hard to tell which supplements are worthwhile and which ones should be left on the shelf.

So in the following article, we will be telling you the important facts about glucomannan as an ingredient, highlighting the supplements that have the most benefit and answering important questions about weight loss supplements.

What is Glucomannan?

also known as konjac. While this ingredient is fairly common in Asian cuisine, it is not featured prominently in western foods.

However, it has been shown to be effective for weight loss because it is a dietary, water-soluble fiber. And as a dietary fiber, it can help slow down the emptying of the stomach.^[1]

This not only allows your body to extract more nutrients from the foods you eat; but also increases satiety time. In essence, taking a glucomannan supplement will help you feel less hungry in-between meals.

How Effective are Glucomannan Supplements for Weight Loss?

Glucomannan has been proven to be effective for weight loss in both animal and human tests. For example, the National Institutes of Health concluded a study that showed that people taking glucomannan lost an average of 5.5 pounds over the course of just eight weeks.^[2]

One of the reasons that glucomannan is so effective for weight loss is because it helps draw more water to the stomach. This means you feel fuller when you eat even though you may have eaten less than you normally do.

There have also been studies that suggest that glucomannan supplementation also has a beneficial impact on your digestive system.^[3] Because it can draw more water to your stomach, it can also improve bowel movement regularity, comfort and help reduce indigestion symptoms like bloating and excess gas.
