Zusto is a unique and innovative sugar substitute which is made from naturally derived substances, namely dietary fibres of corn and chicory. These fibres deliver the sweet taste and structure of traditional sugar.

Zusto can replace sugar on a 1 to 1 weight basis, so this means that the structure, texture and taste of the original product does not alter. Also, it does not have an after taste sensation.

Zusto has 75% less calories than normal sugar. 100g sugar = 400 kcal vs 100g Zusto = 98 kcal.

Zusto is ideal for diabetic patients as it has a low glycaemic index of 22. The fibres in Zusto naturally lower blood sugar levels.
The corn and chicory fibres in Zusto have an additional prebiotic effect on the human intestinal flora. This can lead to a healthier digestive system.

    This is a great substitute for sugar and tastes lovely in baked goods. The cupcakes that I made tastes as good as those made with real sugar and their is no aftertaste either.

    I’ve been experimenting using Zusto in my Jams. As it’s so expensive I’ve just concentrated on strong flavour jams that don’t require so much per pot. Blackcurrant, Damson and Seville Marmalade. I did have a little trouble getting it all to dissolve, but I’m sure its a learning experience.

  23. Robert Davis (verified owner)

    Excellent product that is helping my wife and myself to help our ongoing health issues. Great on cereals…

  26. Karen O. (verified owner)

    Best tasting sugar substitute I’ve tried. I requested a sample which was quickly posted to me since I didn’t want to commit to the expense if it had an unpleasant after taste. Very happy with my purchase. How ever it’s worth reading the advice on the packet about mixing it with butter

  27. Pam E. (verified owner)

    I haven’t tried it yet as still using up another brand. It was recommended and when I read about it I decided to give it a go.

  28. Ray C. (verified owner)

    Fast delivery. Great product, I use it as I was diagnosed pre diabetic. By changing my diet and including Zusto, I now have a lower blood glucose level.

  33. Carole Venner (verified owner)

    Zusto is a perfect alternative to sugar, if rather expensive

  34. Deborah Nealis (verified owner)

    Best sweetener found yet. Bit pricey but no after taste so worth it

  36. Ezabel S. (verified owner)

    LOVE ZUSTO ALWAYS! Been buying since Oct 2020 and never stopped. The best for my keto diet.

  37. Claire Ruddock (verified owner)

    best sugar substitute Ive tried and I have tried many.

  38. Ezabel Siek (verified owner)

    Been using Zusto since Oct 2020 and the longer I use it, the more I know how to work with it. Zusto is excellent for baked goods that require moisture like cakes and muffins. It doesn’t make cookies crisp but it makes it chewy if you like. I have learnt to mix Zusto with other sugars or sweeteners for best results. Being on a low carb/keto diet, I mix erythritol and Zusto to have a perfect sugar-like neutral taste with a roughly 3:1 ratio of 3 parts erythritol and 1 part Zusto when I attempt crispy cookies. For savoury, Zusto is amazing without flaw. I usually add a few teaspoons to stews, sauces, glazes, and especially to caramelise. It is an excellent substitute for allulose (which is hard to come by in the UK) and Zusto makes perfect caramel, butterscotch and toffee sauces. I am a huge supporter and will continue to be! Thanks for the love, Zusto!

  39. Michael B. (verified owner)

    The best sugar substitute I have found by a country mile. All the family have changed over to Zusto without knowing and haven’t noticed it’s not sugar. Excellent

Its even better to bake with than regular sugar and I haven’t put any weight on and can feel the difference as its completely natural! 100% recommend people to try it!

  67. Ezabel (verified owner)

    Happy that this replaces allulose well in terms of making caramel or caramel products. It doesn’t do great with cookies or biscuits as it puffs up instead of crisps. Would be ok with cakes or soft baked products. But I’m happy it caramelises perfectly. Absolutely zero aftertaste. But lots of flatulence!

  68. Henry James (verified owner)

    I have to make sure not to leave packet open too long otherwise no other comments

    Although very powdery it does not have any after taste like other sweeteners or sugars that aren’t the really thing. I have never been able to enjoy a cup of tea without real sugar so when I tried it in tea was a little unsure what to expect so am very happy that I can’t taste the difference. Now using in baking as well. A shame its not cheaper though but if more people catch on, who knows it could drive the prices down hopefully

  138. Nicola Kirk (store manager)

    Now I have to say I am absolutely blown away by this product. I can honestly say I have tried all the other sugar alternatives and have been longing for a product like this. 75% less kcal! I take 2 sugars in my coffee and I must admit I probably have more coffees than I should in a day 🙈 this is the first time I have drank a coffee with an alternative sugar and enjoyed every sip without pouring it down the sink and making a fresh cup with sugar! I have no aftertastes in my mouth what you usually get with sugar alternatives and sweeteners. I most certainly will be recommending this product to all of my friends family and colleagues.

  139. Lorraine T. (verified owner)

    Tastes great, only wish it was a little cheaper! other than that i would totally recommend it to anyone that hates the after taste of sweetenter. being a diabetic its nice to have someone that isnt horrible to use in a cuppa tea/coffee.

    Having recently been diagnosed as prediabetic, I thought it prudent to source a decent sugar replacement. I had always been a ‘white with two sugars’ coffee drinker, ever since my folks introduced me to real coffee…
    Anyway, Zùsto fulfils its claim as a 1:1 sugar replacement. I have not had the opportunity to use it in baking, or confectionary, but I can’t imagine it would be a problem.
    I have ceased sugary, carbonated drinks, and sweets and chocolate, and have stuck to plain or sparkling water. Hopefully my coffee habit at least, can continue thanks to Zùsto.

    What a fantastic product! Not only did it arrive quickly but was packaged well and came with detailed instructions on its use when cooking. I have already used Zusto to make sugar-free vegan brownies and rocky road, both of which were a huge success – could not recommend this product more 🙂

    Found Zusto sugar substitute after being diagnosed with Type 2 Diabetes. Very happy with its taste when used in hot drinks, but seems to set hard when put on cereals. It doesn’t leave any aftertaste like other sweeteners seem to do.

  157. rosalind shaw (verified owner)

    I am very happy with this product already have done some baking and don’t feel guilty eating it , I also made some icing sugar that turned out really good . I would recommend zusto but think it is a bit on the expensive side .

  159. Katie Murdoch (verified owner)

    I purchased this for my grandparents who are both diabetic. They are very pleased with the product and find it much better than other artificial sweeteners they have tried. It’s even made a difference to their sugar levels, so the doctors were pleased too!

  160. Penny (verified owner)

    Love this, have made a cherry and choc chip Bundt cake and added it to yoghurt and double cream which is divine. No funny aftertaste or cooling effects. Doesn’t seem to go crunchy when cold either. Can’t wait to try it in jam. Great product and about to order more. So glad I tried it after seeing it on Facebook.

  161. tonifarrington (verified owner)

    Really pleased with the taste of Zusto. I’m using it in my tea and coffee and there is no weird after taste that you get with some artificial sweeteners. I love the fact that this is a natural alternative with no nasty chemicals. Great product thank you!

Zusto® contains a combination of specific dietary fibers that have been specially selected because of their health value and their excellent qualities as a sugar substitute in all kinds of applications. Moreover, they reinforce each other’s work.

Zusto®, like sugar, gives sweetening power and structure to the products in which it is used. Zusto® owes its sweet taste for the most part to the fibres used. For an identical taste experience, including the characteristic peak that causes sugar, we add an intensive sweetener. Usually it is sucralose, a substance made from sugar with a strongly comparable sweet profile.

The fibres not only provide sweetening and structure, they also offer a number of health benefits and prebiotic effects. After all, eating more fibre is healthy: they form a food source for good bacteria and thus promote healthy intestinal flora. In addition, they allow a substantial reduction in calories. For example, strawberry jam prepared with Zusto contains almost 70% fewer calories. Diabetics can also safely use the product. Zusto is also gluten-free.


For best results, ensure that you keep Zùsto sealed once opened – all our bags have a resealable tag on for this purpose.
