About This Product

  • Promotes satiety
  • Provides digestive support
  • Suitable for everyday wellness seekers
  • Free of gluten, dairy, soy, nuts, sugar, salt, preservatives, and artificial colors or flavors

Derived from the konjac root, glucomannan is a water-soluble fiber often used to promote satiety, or the feeling of fullness. It's also considered a "bulking" agent, which yields bulkier stool that smoothly passes through the colon with less strain and pressure.

Taking three The Vitamin Shoppe® brand Glucomannan capsules with a tall glass of water before mealtime is a great way to get that fuller feeling while supporting digestive health.

Excellent fiber and price
Works for slowing glucose absorption. I take a few with water before a big carb meal. I keep these in my purse. Helps my digestion and elimination too. I also take psyllium husk for a double whammy.

It works!
I was skeptical when I first bought this. There are claims out there that don't deliver. My 1st dose was today. I got up this morning. Did not eat or drink anything. I took 3 capsules as the bottle instructed and I drank a bottled water within about an hour. It works! I have not been hungry all day and made myself eat something. I did go to the bathroom like 3 times (#2) today but I think it's from my stomach being full and it was pushed out. The key to this working? Drink water at least

For Weight Management = this Works well!
If you are trying to extend a fast between meals and manage your weight/health, this product fits the bill. The soluble fiber wards off tummy rumbles but does not interfere with your next meal. Best "snack substitution" out there!

Capsule not dissolving
I just bought these and have been taking them with no noticeable effects. I found out why...sorry to say but they are coming out like they go in. For some reason these capsules are not breaking down at all. I tried them from two different bottles. Yesterday at 4pm I put one in a glass of water. 17 hours later it is still in one piece. I don't have this issue with any other Vitamin Shoppe product...and we usually go for the store brand for quality.

Not worth it
That is the worse quality of a product does not really expand I put two capsules in a half cup of water it didn't even thinking the water. So if you are buying this product thinking that it will expand so you can feel full before meal save your money please thank you.

Why did you choose this?

Maintains my weight using healthy fiber.

Helps me with digestion.

Keep me full, and not over eat

need fiber

Do you take 3 pills before each meal (ex. 3 pills before breakfast, 3 pills before lunch and 3 pills before dinner, daily total of 9 pills) or 1 pill before each meal (daily total of 3 pills)?

  My Husband takes one in the morning and two in the evening, otherwise it is too much.

  3 before each meal

Does this supplement conflict with High Blood pressure / thyroid medication Also has anyone been on Hormone replacement therapy and had any success with this supplement?
I was taking 1 capsule before each meal. I just read the directions again and it says 3 capsules before meals. So you take 3 capsules before every meal, so 9 capsules a day? That seems a bit excessive.

  I have been using these in my smoothies by breaking the capsules and blending it...Its important to drink the smoothie immediately, otherwise, it turns into pudding...These capsules are suppose to make you feel full. I do not eat 3 times a day so use these if you want to eat less and feel full.

  I was taking 1 capsule per meal

  I am not a medical professional but I feel that 6/day is excessive. But then 3/day sounds excessive. The goal is a happy balance where you feel good.

How old do you have to be to buy this product?

  I really don't know that. But because it's an herb and not regulated by fda I would think there is no age requirement. Hope that helps

  any age with money

  I think 18

I need to lose 35 lbs and I figured if this was on Dr. Oz it must be good and work. Will this really help me lose those pounds? I have started an exercise program 3 days a week.

  If you tend to over eat, this may be the answer. The konjac root is a natural fiber that expands, so there is less room in your belly. Meaning if your stomach is already full, you should eat less. If overeating is your issue AND you can remember to take it 30 minutes before you eat, this will probably help. Although I never lost more than a couple of pounds using this product alone. I can tell you, it does help with eliminating some of that "belly pooch" that women tend to get. I expect that is the "fiber" aspect. You will become very regular. Also, please remember to drink lots of water with this product. You need it to ensure this passes through your body. I have read reviews of people becoming ill and having a difficult time with it. I think because they were not drinking enough water. I never had any difficulty. Good luck with your weight loss efforts!

  This product will assist with a normal healthy diet and exercise. It does help curve the appetite a little so you don't eat as big of a meal. Weight Watchers plus program is a great way to teach a person to eat properly and maintain that proper eating. I used this product to help with my eating, so I didn't eat a big a meal as I use to and has helped with weight loss.

  i lost a few pounds taking it, while doing little else. i think you are wiseto throw in the exercise. i did try to watch what i ate a bit, but can't say i actually dieted. if you curtailed calories and exercised, i think it would speed up your loss. it also makes you nice and regular; always a benefit.best of luck,h :)

Do you have to take the pills a half hour before a meal or can you take the pills right away before you eat?

  30-60 minutes before is definitely better, however, I have found that even if I take it right before a meal, as long as I have a nice full glass of water (at least 12 oz or so) right afterwards, it still definitely helps... just make sure to eat your meal a little more slowly so you don't overstuff yourself!

  If the reason you take this is to lose weight, then you should try to take them a half hour or one hour before you eat to fill you up so you won't eat as much. If you are taking this to increase your fiber, then taking them with meals works the same for me.

Thanks for the tip.

  You should take it a half hour before a meal with water for it to expand; giving you a feeling of fullness.

Thank you for the tip. I wish it said that on the bottle.

Why can't I take it before bedtime?

  My Husband takes one in the morning and two in the evening.

  Because it gives you energy, so it is more suitable to take it at lunch time!

  Can this be taken with Garinia Cambogia?

Vote for the best answer above!

My biggest problem is in my stomach area, has anyone had amazing results?

  Not amazing, but consistent if I follow a sensible diet. I have IBS, and the fiber also helps control that. Good luck!

  I found no results from this product so I never bought a 2nd bottle.

  Works well for my Husband and it does not contain soy.

Vote for the best answer above!

To those who suffer with IBS-constipation, does this product cause trapped gas & bloating?

  I do not know the answer to that. You may want to ask a doctor or just google that question and see what you can come up with. But my experience is that it fills you up. I break open a capsule or two in my smoothie and use it as a filler. But hurry and drink because it practically turns to gelatin if it sits too long.

  Helps move things along.

Do you know how many mg's this product is? I can't find it anywhere..

  My bottle says 1.99 g per serving. 3 pills make up one serving.

  Hi, The product is labelled indicating there is 1.99 G per 3 capsules, that comes out to 666mg per capsule. It may seem like alot but we're talking about fiber here, not mg amounts as related to vitamins or medications. So taking 3 caps before each meal adds 6 grams of fiber daily. Fiber that slows the absorption of carbohydrates and helps you to feel full.Hope that helps

  The amount of Glucomannan in 3 capsules is 1.99 grams which is equivalent to 1,999 mg. Hope this answers your question.
