Why Zilch is the UK's number 1 monk fruit brand

Pick up almost any "monk fruit sweetener" on a UK shelf and check the ingredients: it's usually mostly erythritol with a trace of monk fruit. Zilch isn't, and that single difference is why it became the best-selling monk fruit sweetener on Amazon UK. It's a whole-fruit-derived monk fruit infusion powder from an Edinburgh-based UK brand, with no erythritol, no sugar alcohols and no artificial additives. For a lot of customers, that one line on the back of the pack is the whole reason they switched.

Why customers switch, in short

• Zilch is the best-selling monk fruit sweetener on Amazon UK, from a UK company based in Edinburgh, trading since October 2025.
• It's a whole-fruit-derived infusion powder, not a purified extract and not an erythritol blend.
• No erythritol, no sugar alcohols, no artificial additives and no added sugar; it's also high in fibre.
• Around three times sweeter than sugar, with a cleaner taste profile than the usual bulked-out blends.

What does "UK number 1" actually mean?

We think it's important to be precise about this claim, because plenty of sweetener marketing isn't. When we say number 1, we mean Zilch is the best-selling monk fruit sweetener on Amazon UK, the largest single marketplace for this kind of product in the country. It's a straightforward sales position on a single, transparent platform, not a made-up market-share figure.

That matters because Zilch is a young brand. We've only been trading since October 2025, so reaching the top spot in that category on Amazon UK in that time tells you something real: people try it, and enough of them come back and recommend it that it climbs. For a new independent brand competing against much larger names, that's the metric we're most proud of.

What makes Zilch different from other monk fruit products?

Most of what's sold as "monk fruit sweetener" in the UK is a specific formulation: a highly purified mogroside extract blended with a large amount of erythritol so it measures spoon-for-spoon like sugar. The monk fruit is often a fraction of a percent. Zilch is built differently.

1. It's whole-fruit-derived, not a purified extract

Zilch is made by infusing and decocting the monk fruit, rather than isolating one purified compound. That process keeps a broader mix of what's naturally in the fruit: mogrosides, small amounts of the fruit's own naturally occurring sugars, fibre and plant compounds. It's far less concentrated than a purified extract, which is why Zilch is around three times sweeter than sugar rather than the 100 to 250 times you see quoted for isolated extracts. You only need a little, but it behaves more like a real ingredient than a lab-tuned intensity hit. We'll be honest about the trade-off: the whole-fruit route costs us more to produce than bulking a purified extract out with cheap erythritol would, and it doesn't measure spoon-for-spoon like sugar. We took that hit on purpose, because the alternative meant putting a sugar alcohol front and centre in something called a monk fruit sweetener. If you're curious why the whole-fruit approach costs more, we cover that in our piece on why monk fruit is so expensive.

2. No erythritol and no sugar alcohols

This is the differentiator customers mention most. Erythritol is a legitimate, approved additive (E968) that's widely sold across the UK and EU, and it's the bulking agent in most supermarket monk fruit blends. It's also the ingredient dietitians tend to be most cautious about, since it can cause bloating or a laxative effect in some people in larger amounts. Zilch simply takes a different route: it contains no erythritol and no sugar alcohols at all. Instead of bulking the powder with a sugar alcohol, we use a soluble tapioca fibre carrier, which is where the fibre content comes from. If avoiding erythritol is what brought you here, that's exactly the gap Zilch was made to fill; we go deeper in our guide to Monk fruit without erythritol.

3. A cleaner, simpler label

No artificial additives, no added sugar, and a short ingredient list. Because it isn't engineered to be intensely sweet or to mimic sugar's exact volume, it tends to have a cleaner taste profile than heavily bulked-out blends. Taste is personal, so we won't promise it's identical to sugar, but the whole-fruit route is a large part of why customers describe it as rounder and less harsh.

4. High in fibre

The tapioca fibre carrier means Zilch is high in fibre, which is unusual for a sweetener. It isn't a reason on its own to buy it, but it's a small bonus rather than a filler that works against you, which is how erythritol tends to be framed. Most of us in the UK fall short of the recommended 30g of fibre a day, so the NHS guidance on getting more fibre into your diet is worth a read whatever sweetener you use.

How do people use it?

Because Zilch is around three times sweeter than sugar, you only need a small amount, so the calorie and glycaemic impact is negligible at the amounts typically used. Customers use it the way they'd use any everyday sweetener:

• Stirred into coffee, tea and matcha.
• Across smoothies, yoghurt and porridge.
• In baking and cooking, adjusting for its higher sweetness so you use less.

It's sold in 80g and 160g packs, with subscribe-and-save available for people who go through it regularly. If you're cutting back on free sugars for health reasons, Diabetes UK's advice on sugar is a sensible starting point.
