Sugar alternatives in powder, granules, tablets and drops: stevia, erythritol, xylitol and monk fruit. We explain which sweetener suits baking, which one suits coffee, and how much sweetness you actually need.Read more →

Sugar alternatives: which sweetener fits which use
Sweeteners give food and drink a sweet taste without the sugar. Two groups do the work. High-intensity sweeteners such as steviol glycosides, taken from the stevia leaf, and monk fruit extract are many times sweeter than sugar, so a pinch replaces a spoonful. Polyols, also called sugar alcohols, such as erythritol and xylitol, sit closer to sugar in sweetness and in volume. That is why they are sold in bags, while stevia arrives in small bottles and sachets.
- Steviol glycosides (stevia): no calories, easy in drinks, slightly bitter if you use too much
- Erythritol: granulated, mild, leaves a cool sensation on the tongue
- Xylitol: tastes closest to sugar, never safe around dogs
- Monk fruit: fruity note, usually blended with erythritol for volume
Form decides how a sweetener behaves in your kitchen
The form is not a detail, it changes the result. Granulated erythritol and xylitol measure spoon for spoon, so they hold up in cakes, custards and anything where bulk matters. Pure stevia or monk fruit powder is so concentrated that a scoop the size of a match head sweetens a mug. Overshoot and you get a bitter, liquorice-like edge. Drops dose neatly into coffee, yoghurt or a shake. Tablets suit tea and travel. Blends pair erythritol with a little stevia to keep the sugar-like volume while softening the cooling taste. For a low-carb, keto approach, granulated blends are the usual baking choice.
How we choose the sweeteners we stock
We look at three things: the form, the amount of sweetness per serving, and whether a combination has a purpose. We prefer granulated erythritol for baking because it measures like sugar, and concentrated stevia drops for drinks because a few drops are enough. We stock blends only when the second ingredient does a job, for example stevia lifting the sweetness of erythritol without adding bulk. We buy directly from the brands, our compliance team checks every label before it goes live, and independent labs spot-check batches. Read how we select brands and products.
Who these products suit, and what to expect
Sweeteners fit people cutting sugar in tea, coffee, baking or breakfast, and people who still want dessert. Two claims are approved for this group in Great Britain. Foods and drinks made with sugar replacers instead of sugar cause a lower blood glucose rise than the sugar-containing version. Sugar replacers also contribute to the maintenance of tooth mineralisation by reducing demineralisation. Both depend on actually replacing sugar, not adding extra sweetness on top. If cutting sugar is part of wider weight management goals, that distinction is the practical one.
Be realistic about two points. Larger amounts of polyols can cause bloating or a laxative effect, and tolerance differs per person, so start small and build up. Taste also needs adjusting, roughly one to two weeks, before a stevia-sweetened yoghurt stops tasting unusual. Some people decide they would rather train their palate down and pick products without added sweeteners instead. Both routes work; a sweetener is a tool for using less sugar, not a health food in itself.
Frequently asked questions
What are natural sweeteners and how do they differ from sugar?
They are ingredients that add a sweet taste with little or no energy. Two families exist. High-intensity sweeteners such as steviol glycosides from the stevia leaf and monk fruit extract are used in tiny amounts. Polyols, or sugar alcohols, such as erythritol and xylitol, are only partly absorbed and give bulk as well as sweetness. Unlike sugar, they are not fermented into acid by mouth bacteria, which is why the approved dental claim exists for sugar replacers.
Which sweetener suits baking, drinks or protein shakes?
Match the form to the job rather than looking for one product that does everything.
| Use | Best suited | Why |
|---|---|---|
| Cakes and biscuits | Granulated erythritol or blends | Measures like sugar, gives bulk |
| Tea and coffee | Stevia drops or tablets | Dissolves fast, easy dosing |
| Shakes and yoghurt | Stevia or monk fruit powder | No grit, no extra volume |
| Chewing gum, mints | Xylitol | Closest taste to sugar |
For a plain shake, a few drops in an unflavoured protein powder often beats buying a sweetened version.
How much sweetener replaces a spoonful of sugar?
It depends entirely on the type. Erythritol is slightly less sweet than sugar, so most people use a little more than a spoon for a spoon. Xylitol is roughly equal in sweetness and volume. Pure stevia and monk fruit extracts are far sweeter, so a level micro-scoop or a couple of drops replaces a teaspoon. Always start below what you think you need. Too much high-intensity sweetener creates a bitter aftertaste you cannot cook out.
Can sweeteners upset your stomach?
Polyols can, in larger amounts. Erythritol, xylitol, sorbitol and maltitol are not fully absorbed, so part reaches the large intestine and may cause gas, bloating or looser stools. Erythritol is usually the gentlest of the group, sorbitol and maltitol the least gentle. Tolerance is personal, so build up over a week instead of baking a whole cake on day one. High-intensity sweeteners such as stevia are used in such small amounts that this rarely applies.
What can sweeteners genuinely do compared with sugar?
Two effects are approved, and both are modest and conditional. Foods and drinks made with sugar replacers instead of sugar cause a lower rise in blood glucose than the sugar-containing version. Sugar replacers also contribute to the maintenance of tooth mineralisation by reducing tooth demineralisation. Note the wording: the sweetener has to replace sugar, not sit alongside it. UK advice remains to reduce free sugars overall rather than simply swapping every sweet item for a sweetened one.
Are there official daily limits for sweeteners?
Yes, for the additive sweeteners. Regulators set an acceptable daily intake, or ADI: the amount that can be consumed every day over a lifetime without appreciable risk. For table-top use the ADI is hard to reach, because the amounts in a cup of coffee are small. Polyols such as erythritol and xylitol are limited in practice by digestive comfort rather than by a numeric table-top figure.
| Sweetener | ADI (mg per kg body weight per day) |
|---|---|
| Steviol glycosides (E 960) | 4 |
| Acesulfame K (E 950) | 15 |
| Aspartame (E 951) | 40 |
Which sweeteners hold up to heat and to yeast baking?
Erythritol, xylitol and steviol glycosides stay stable at normal oven temperatures, so they work in cakes, crumbles and custards. Aspartame loses sweetness with prolonged heat, which is why it belongs in cold drinks. Two practical limits remain. Sweeteners do not caramelise, so you lose browning and that toffee note. And yeast cannot ferment them, so bread dough needs a little real sugar or honey to rise. Expect a different texture, not a copy of the sugar version.
Why is xylitol a serious risk around dogs?
Xylitol triggers a strong insulin release in dogs, which can drop their blood sugar dangerously fast, and larger amounts are linked to liver damage. Humans do not react this way. Very small quantities can affect a small dog, so keep bags, baked goods and sugar-free gum out of reach and never share a home-baked treat. If your household includes a dog, erythritol or stevia is the easier choice. Contact a vet immediately if a dog eats xylitol.
