    Glucomannan (Konjac) is a form of water soluble fibre, which has been shown in research to contribute to weight loss in the context of an energy restricted diet, at a dose of 3g per day. Glucomannan is sourced from the rhizomes of the Amorphophalli Konjac plant, generally found in South-East Asia.

    Glucomannan (Konjac) increases the feeling of fullness (satiety). Glucomannan (Konjac) Powder has also been shown to contribute to the maintenance of normal blood cholesterol levels, at a dose of 4g per day.

    Gave me stomach cramps Review by Rinkidink
    Another reviewer found it helpful for IBS and that it's better than laxatives, but it made my digestive issues worse. It blocked me up and gave me cramps every time I had a stool, which also took a lot longer to accomplish. Pity, I like Konjac for its usefulness otherwise.

    Beware if you have a sensitive gut, it seems it may help or make things worse. I found other people online saying it gives them stomach cramps too. It must be an individual thing. (Posted on 28/12/2017)
    Slightly gritty Review by Linzfp84
    This has a slightly gritty texture but nothing unbearable, I add a splash of cordial to it to help it go down. I do find that this stops me over eating and appears to help with watching my weight. (Posted on 06/12/2017)
    Great thickener Review by MS
    Great for adding to a whey shake to make a thicker mousse like dessert. Works really well and versatile as can be added to anything liquidy. Very good value in the larger bags (Posted on 03/12/2017)
    Middle of the road Review by Rny12
    Ive tried Glucomannan now in two forms. As far as supplements go i dont think its benefit or impact weighs up well with cost. I find the effects minimal, but others may be different. (Posted on 01/12/2017)
    Full for longer Review by Kim
    Add this powder to my shake and to say it works i sometimes have to waste just less than quarter as i get full. Perfect for me when im hungry alot this solves the problem. (Posted on 15/03/2017)
    Changed my life! Review by DianaB
    I know that sounds extreme but as someone who has suffered with IBS for 15years and has taken every kind of fibre and other abrasive concoctions like laxatives & muscle relaxants, I'm so happy to have found this product. I mix it in with my shakes in the mornings, not only does it thicken it and make it creamier tasting (to me) it also keeps me fuller for longer and has really helped with my IBS symptoms and weight management. Cannot recommend enough. (Posted on 08/01/2017)
    I like it Review by Witzend
    Great to add to smoothies and will try as a thickener.

    Mainly bought for the fibre to help counteract medication side I have IBS/biliary issues I find this works well without upsetting my tum at all. Most commercial laxatives give me crippling pain and need to be taken in large amounts .. this is the best thing I have tried in years.

    Make sure you use sparingly and add a little at a time whilst keeping your fluids up.

    Brilliant service as always from bulk powders (Posted on 07/10/2016)
    Just add little by little Review by FionaFaytv
    The mixing of Konjac flour can go horribly wrong if too much is dumped into the blender or soup!!! Only add a tiny bit by bit gradually. It really does magically thicken up shockingly quickly when you least expect it lol!
    Good stuff though! Great for vegan jelly, zero carbs jelly, bulking fibre. As long as your water constant is sorted. NEVER ever use this powder dry!! (Posted on 31/12/2015)
    Gritty bits :/ Review by Luce
    As I haven't had it before this may just be the general, average texture of this product but it is inconsistantly gritty like there are tiny weeny bits of grit in it :( and I'm not sure if that's normal. It would be expected as it's a root but it's not pleasant so I doubt it's just what the powder feels like. I'm guna stick with it (and hope it's not grit I suppose it could be minute parts of the roots skin?) and add it to different things in different amounts and see if there's any change. All in all so far it seems to help fill you up so you eat less of other stuff and doesn't have an unpleasant taste so it's not all bad :) . (Posted on 19/12/2015)
    Good, however read the instructions! Review by Matt
    Recently had a bad experience with this product. It's great for keeping you full, but as soon as you mess up the ratios it's really dangerous.

    Accidentally putting in 2 scoops into a shake has led to my throat becoming blocked by this incredibly fibrous powder and it's a horrible sensation that is leading to a doctor's appointment today in an attempt to remove this 'glue' from my throat!

    Still given 4 stars as it does what it says it does, keeps you full and will 100% aid in cutting. (Posted on 10/08/2015)
    Brilliant in almost anything Review by Amy
    Folks, if you're new to the wonders of glucomannan, here's a tip to avoid lumps: add a scoop or two to a small amount of cold water while stirring and then add it to hot food (thickens broths and sauces), yogurts (thickens and increases volume for no calories), porridge (same deal), and tons of other tasty treats. Wait for 10 - 15 minutes with cold food and it will thicken evenly. I water down my greek yogurt a lot and add this stuff and it thickens right back up so I get to eat way more - I am defying physics and loving it! (Posted on 23/04/2015)
    Not as expensive as it may seem Review by Lo-carb baker
    I've used this product to thicken all sorts of things and it works really well, provided you stir or whisk it thoroughly to avoid lumps. It's tasteless and has a good consistency. You only need a small amount (the scoop provided is tiny) so the bag lasts a long time. (Posted on 12/03/2015)
    Works well, but needs better Instructions Review by Dil
    I put the stated dose into a pint of water and it turned to lumpy wallpaper paste.

    Luckily I had a blender which smoothed it out. Taste with just water is a bit odd so add half a lemon/lime juice or sugar free cordial and some ice cubes.

    Overall, happy. (Posted on 26/01/2015)
    Interesting Review by Goran
    I've only used it twice so far, but the results were good. Mix it together with whey protein, blend in water, leave it to set and turn solid and you get a very low carb protein pudding. Much better than xanthan. Solid but not slimey.

    Good stuff. (Posted on 25/11/2014)
    Fantastic Review by Zoe
    Absolutely fantastic. I have been using Xanthan Gum which is very good at thickening and is more instant than the Konjac but it does have that jelly like texture. Konjac on the other hand does need to be left to set but then it sets solid (unlike the Xanthan gum) and it turns a protein shake or Juice plus etc into the most yummy pud which fills me up more than drinking a shake. It is a lot more expensive but if you add 75% Konjac and 25% Xanthan Gum then it keeps the costs down. Really good stuff, and no taste and hardly any calories. Just about to order another bigger bag :) (Posted on 24/08/2014)
    Great Stuff Review by Claire
    Just started to use this and already notice I'm not feeling hungry. Will see how I progress. (Posted on 26/06/2014)
    Amazing Review by Emma
    This stuff is incredible, it thickens soups, desserts, protein shakes, porridge, just blend with water or milk etc......... and has no carbs or calories what more could you ask for well done Bulk Powders! (Posted on 28/12/2013)
    This really works... Review by Mike J
    Was a little dubious about this stuff as almost seemed to good to be true. If you're the same then all I can say is "give it a go". It removes my hunger pains and stops me from snacking on things that I shouldn't when at work. This alone is helping me lose weight. Using with Complete Thermogenic and the weight is dropping off. Of course I'm hitting the gym hard too :) (Posted on 10/11/2013)
    Excellent stuff Review by Dia
    Well recommended to anyone, like me, who has a very sweet tooth and un-does all their good work in the gym by indulging!

    This comes as a slightly granulated white powder and has a very subtle odour to it - think krill oil capsules mixed with....sherbet!! I mix slightly less than 1/4 teaspoon with 200ml water and gulp it down about half an hour before meals. It has a slight chemically aftertaste (when taken like this), not entirely pleasant but certainly nothing to make you gag. When mixed with water, the mixture become thickened, but nowhere near gunge-y or slimy like other products.

    I tried mixing it with my protein shake but the resultant texture was not to my liking. however, the results of taking this were! It really does make you feel 'satisfied' and inclined to eat less.....without making you lose your appetite (like hoodia does, to me anyway) or making you bloated/experiencing 'digestive issues'.

    A good way to regulate your calorie intake and stop you snacking at work!! (Posted on 12/08/2013)
    Better than Xanthan gum Review by Helen
    Brilliant ingrediant for making low carb protein puddings and it has all the diet benefits of fibre as well! This is what they make zero-calorie noodles out of.

    I mixed a couple of grams in with my protein, blended and it made a protein pudding with the same consistency of those chocolate/vanilla puddings ou can buy in the chilled isle of the supermarket. It does not have the slimy texture that Xanthan gum can have.

    Powder was odourless, tasteless and mixed well. (Posted on 08/08/2013)
