Product Description

Glucomannan is a soluble, bulk-forming fiber derived from konjac root (Amorphophallus konjac) that can help to maintain intestinal regularity.* Glucomannan may also help to maintain serum lipid levels already within the healthy range.* In addition, by promoting satiety (feeling of fullness), Glucomannan can be a convenient addition to a weight management plan that includes a healthy diet and exercise program.

5.0 out of 5 stars When it comes to fiber, quality is the key.
Reviewed in the United States on April 4, 2018
Size: 114 Servings (Pack of 1)Verified Purchase
Glucomannan is recommended by medical authorities as top quality fiber to feed the probiotics in your gut and, ahem, it's easy to see why. To be honest, not much comes out the other end. I'm trying to take it regularly twice a day. It does make a big difference if you take it once versus two or three times a day . And the difference in quality between something like Metamucil and glucomannan is pretty extreme .

Mixed with water, you need to stir vigorously or it will form an incredibly thick jelly that needs to be spooned into your mouth. You can chug it as fast as possible before it has a chance to set.

The powder has just the faintest hint of a fishy taste/smell. However, it's trivially easy to hide. Honestly, I still have some Metamucil left, so I mix a cocktail to get that delicious Metamucil flavor. But chicken stock works so much better.

Will it fix your diarrhea or constipation? Eventually. Glucomannan is soluble fiber. Insoluble fiber is better for regularity. However, it will feed the helpful probiotics in your gut and hopefully, they will destroy any bad bugs. THAT will fix your diarrhea/constipation.

And did you know Shirataki noodles are also made of glucomannan? Nothing but glucomannan. It has no carbs, no calories, no gluten, just fiber. Also sold on Amazon : )

(and your local Asian grocery store)

Update: Recently I saw a doctor of functional medicine to find out what the heck is going on with my gut. We'll find out when the tests come back.

Meanwhile she straightened out my supplement regime. She threw out my junk fiber Metamucil but I was allowed to keep glucomannan. However she recommended PGX instead. PGX is a form of glucomannan which has been processed to preserve the fiber to the max. She also dumped my favorite probiotics, but kept Jarrow's Saccharomyces boulardii . S boulardii is a probiotic that fights inflammation of the gut.

I was stunned , didn't she want more probiotic diversity to help strengthen the microbiome? Wasn't it better to have lots and lots and lots of fiber?

Apparently not . Taking too many probiotics isn't helpful because the probiotics must fight it out in the gut with your already established probiotics so she eliminated the competition to favor S. boulardii which will heal the gut.

What's wrong with taking all kinds fiber? Lots of different fiber? Unfortunately, poorly processed fiber such as Metamucil, sure it supports your probiotics but it also feeds some seriously bad denizens of the gut.

And that was it . Throwing out the junk did the trick . Three weeks after I took her advice my gut pain , cramping, gas, bloating, diarrhea, GERD is under control.

So quality is the key. Buy the best fiber that you can afford. PGX if you can afford it or glucomannan. Get the right probiotic for the job. If you want to control inflammation Saccharomyces boulardii is the right probiotic and you won't need any other probiotic.

Healing the gut is a big story and here are some other helpful elements.

Glutamine . 2 to 3 g daily is the therapeutic dose to heal the gut glutamine feeds the gut directly.

Resistant starch : resistant starches are longchain starches that resist digestion. They are usually broken down by the probiotics in your gut . Some of the byproducts of resistant starch digestion are used to feed the gut directly and they reduce inflammation . Bob's Red Mill unmodified potato starch is resistant starch. The therapeutic dose is 1 tablespoon taking up to three times daily.

Collagen: collagen is required to heal the gut. You can find collagen either in bone broth or collagen powder.

If your digestion is broken : gas, bloating, stomach aches, heartburn, cramps, diarrhea, GERD. You may need to support your digestion. You want to check with a physician before starting this because if you don't need this stuff you could burn a hole in your stomach. HCL betaine and digestive enzymes .

, you need to initiate protein synthesis. Healing is by definition the production of new proteins to replace those which are broken or missing. In order to initiate protein synthesis, you need to eat 30 g of protein in one sitting. That's a lot of protein, five large eggs contains 30 g of protein for example. I tend to do this by eating 30 g in one meal. And then for my other meals that's when I eat all my vegetables and fruit.

5.0 out of 5 stars Amazing
Reviewed in the United States on February 19, 2016
Size: 114 Servings (Pack of 1)Verified Purchase
Amazing.

A little goes a looong way. I take about about a teaspoon a day during a meal or before a meal. I haven't taken more than once a day and to be frank, after taking a tablespoon of this one time, I am quite deterred and terrified of taking more than 1 tsp a day. I'll explain why a little further down.

Now, as for effectiveness, if I take this and glutamine consistently, I have zero doubt I will lose a lot of weight over time. My problem with eating is related to bulk. If my stomach isn't satiated with volume, I cannot stop eating. And eating veggies to fill up that quota is not appealing to me. Here is where glucomannan comes in. It is pure fiber. This stuff holds fluid and sits like a gel in my stomach. When I take this in my food, it makes me feel like I ate a feast. And yes, from only 1 tsp. If I take this before a meal everyday, I definitely eat a lot less. The glutamine, in case you're wondering, helps with my sugar cravings so I don't feel the need for sugar so much. If I take these two in tandem consistently, I think my weight will drop like falling off a building.

But I don't take these two consistently. Why? Because it's hard for me to add glucomannan to food. I can only add it to soup or some sort of creamy beverage if I have it on hand. The texture of this is rather gritty and God help you if you add this to hot foods or soup. It will expand and become this viscous goop that you will definitely have trouble eating, because it's no longer about that drinking. And another thing is if I take even 1 tbsp (TMI), I will get diarrhea. Like intense diarrhea. Like if you read that epic win comment (which i highly suggest you read for entertainment) about those sugar-free alcohol haribo gummy bears and that reviewers' runs in the bathroom, this is probably not as bad. But it is awful nonetheless. So with that said, I get nervous if I take more than 1 tsp which means I dont take it often or as consistently due to texture/the runs.

But this stuff is sugar free, healthy and a great alternative to things like xanthan gum, corn starch, thickeners, etc if you're into healthy cooking. And it's great for weight loss and appetite curbing if that's your goal.

4.0 out of 5 stars Low Carb / Keto Friendly - Excellent thickener for stews/gravies/sauces
Reviewed in the United States on June 10, 2018
Size: 114 Servings (Pack of 1)Verified Purchase
I'm on a keto (ketogenic) diet and did some research on thickening agents to use in place of corn starch or flour. I ordered this to make a recipe in my slow cooker for Mongolian Beef and it worked great! My husband couldn't believe that the recipe didn't have flour in it. It has no slimy mouth feel - and no taste whatsoever... it has a much higher thickening power than corn starch (I used 2 teaspoons of this stuff for a recipe that called for 1/4 cup of corn starch). My research said this could also be used in shakes/smoothies/coffee drinks to thicken things...and I did try it for that...and it did work....but it made the smoothies I made have a weird consistency so I am not sure that I like it for that. They weren't bad...just had an odd thick but very light/airy consistency that I wasn't going for. I think very good for stews, gravies and other sauces. I would definitely buy it again.

As an added bonus this is often promoted as a nutritional supplement for weight loss and lowering cholesterol and is supposed to be good for diabetics. I am not using it for those things--but if that's an added benefit, all the better!

Delivered in good condition. It's great at keeping one full - by taking 30-45mins before a meal - really helps control the appetite and keeps you fuller for longer. But make sure you drink ALOT of
Water throughout the day because glucomanan is known to soak up to 5 times its weight in water. If you don't drink enough you will feel constipated.
But this stuff is great to add to an already healthy lifestyle or weight loss regime.
