For business customers, please contact us for commercial pricing and any other information relating to Zusto.



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.

    I wanted to make jam for a relative who is diabetic and Zusto was recommended. It has worked perfectly- the jam has set beautifully and the taste is very good.

    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

    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.

    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.

    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.

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.
