What Is Glucomannan Powder And How Does It Influence Your Body?

Glucomannan powder is a naturally occurring nutritional fiber that comes from the konjac plant. For years, it has been used as a thickener and emulsifier with countless cooking applications.

Surprisingly, there are many claims of significant health benefits.

Some studies support its ability to help lower your blood pressure and fight obesity. However, its ability to help reduce cholesterol levels is still up for debate.

Luckily, there is no doubt that if you mix this powder with water and drink it before each meal, you are not going to be able to eat as much as you normally would.

The Way This Substance Works

With no starch or sugar content, this substance is basically a calorie-free carbohydrate in the form of fiber. If you have ever taken such supplement, you already know that it can drastically reduce your appetite.

The fibrous content is soluble, so it tends to attract water (this is where the “magic” lies). When it comes in the contact with water, it forms a gel, helping to slow down your digestion. Therefore, filling up your stomach with glucomannan powder before a meal will help you to eat much less and still feel full!

Therefore, filling up your belly with glucomannan powder before a meal will help you to eat much less and still feel full! Because it quickly gels up, you need to dissolve this powder in your glass of water and drink it as soon as possible.

Pay attention: This substance, like any fiber, doesn’t get broken down and absorbed into your bloodstream; it remains intact and only passes through your digestive system.

You Can Easily Add It to Your Meals

Another beneficial property is the fact that it is without any odor as well as without almost any taste so you can add it to just about any recipe that would normally include cornstarch.

If you do not like to use supplements to meet your daily need of dietary fiber, then there are many fiber-rich foods you can eat, such as bran, beans, seeds, nuts, and dried spices.

The key to using glucomannan powder in your cooking is to remember to add it to cold or tepid water only. If you add it to the hot water, it will thicken and turn into gel almost instantly.

Pay attention: By adding glucomannan powder to your daily meals you are taking in the fiber that you need without the chalky taste.

Great Benefits for Your Body

Except being a useful thickening agent for your meals, the extract from Konjac root has many applications and benefits for your body as well. You are now probably thinking:

“Why would I want a big glob of gel going through my system?”

Well, the answer is easy as it comes with many benefits:

  1. This substance induces satiation or the feeling of being full. This is especially important if you are trying to lose weight and minimize your sugar cravings.
  2. It helps to cleanse your body of toxins and to prevent constipation.
  3. Glucomannan helps your body to manage blood sugar levels and reduces the insulin spike your body often experience after a meal rich in carbohydrates.
  4. This substance reduces the absorption of cholesterol from your diet and inflammatory patterns in your body.

Pay attention: Modern science has not entirely proved the weight loss aspects of this substance, but if you think about its basic physical and chemical properties, the potential advantages are quite clear. Just check out the section below dealing with various scientific studies on this substance.

Only a few studies have been performed on glucomannan as a dietary supplement, but its benefits have been known for centuries in other parts of the world.

Of several studies that have examined it, the results look quite promising. The powder has been shown to induce satiation, lower cholesterol levels, provide food for good bacteria in your intestines, and cleanse the digestive system.

Comment from Nick

It is neat how you can lower your cholesterol, blood pressure and lose weight with it. I have seen many news reports of dieting pills and powders being hazardous to a person’s health.

For example, I read that in 2009, the FDA found 69 brands of diet pills that were already on the shelves of grocery and health stores, and pharmacies that had hidden ingredients that could cause seizures, liver damage, heart attacks, stroke, and high blood pressure.

So, I personally believe you are better off taking this powder than gambling with your health by listening to TV commercials about all those dietary pills.

Comment from Kelly

I’ve been taking the Nature’s Way Glucomannan Konjac Root capsules for two days now. You take one 30 mins before each meal (so 3 a day) with a full glass of water. I am an overeater. I can sit down and devour a whole pizza by myself no problem. I’ve been looking to lose weight but I have such a hard time because I get so nauseous and light headed when I don’t eat enough.

Because of these pills I eat literally 4 times less than I normally would. Although it’s only been two days, I can tell this is going to work. I would totally recommend them to anyone. An amazing product! I also love how its completely natural. No chemicals or dangerous ingredients to worry about. I’m in love!!

Comment from Anna Adams

This is really interesting because my doctor actually prescribed me a fibre drink to help with an unrelated medical issue I was experiencing. The lemon flavoured powder was mixed with lemon and stirred well until it was dissolved. I had to drink it all right away because if not it would turn in to a thick gel substance.

After drinking it I experienced a real decline in my appetite, I wasn’t eating as much as I normally would. Until now I had never made the connection but that must have been what it was.

I couldn’t tell you for sure if it contained glucomannan but it was certainly pleasantly tasty and helped my other medical problem.
