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 fibers 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 fibers not only provide sweetening and structure, they also offer a number of health benefits and prebiotic effects. After all, eating more fiber 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.

    Zusto is amazing. I was diagnosed with Type 2 Diabetes in February 2019 and just by cutting out sugar and using Zusto instead I am now in remission. It tastes just as sweet as sugar!

    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

    There is no difference between this and actual sugar other than it has a fraction of the calories. amazing product. As for the price you get one kilo of zusto for £975 and no bitter aftertaste as opposed to stevia at £4 for 150 grams

    Tastes like sugar and has no aftertaste. It does need thorough mixing with dry ingredients before adding melted butter or small flecks of it will appear. I have not yet tried baking with it.

    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.

    Taste was good however cake tended to collapse more easily than when used regular sugar. Not good as icing. But like I said taste was good. 😊

    Excellent replacement for sugar and other sweetners, however, it would benefit being in a small cube form or tablet of some kind.

    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.

    At last a sweetener that doesn’t leave a horrible taste in your mouth. Ordering and delivery easy. Product delivered on time and well packaged.

    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.

    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!

    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.

  63. Rated 5 out of 5


    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!
