Sugar-free vegan protein can contain sweeteners. A protein powder without sweeteners can also contain sugars naturally present in its ingredients. To choose between products, check both the nutrition information and the ingredient list.
If you prefer a shake that is not very sweet or want a base for recipes, the absence of sweeteners may matter to you. If you enjoy vanilla or chocolate, you might prefer a different formula. The useful question is what each product contains and how you plan to use it.
What does sugar-free mean for vegan protein?
In the European Union, a sugar-free claim requires no more than 0.5 g of sugars per 100 g or 100 ml, as applicable. That includes sugars naturally present in the ingredients. The European Commission explains the conditions for these nutrition claims.
When comparing two protein powders, use the same basis in the nutrition information, such as the values per 100 g. Then check how much your intended serving provides. A small serving containing less than one gram of sugar does not, on its own, establish that a product meets the sugar-free condition.
If the values refer to a prepared shake, check the amount of powder and the liquid used. Plant-based drinks, milk or fruit can change the composition of the drink you actually consume.
No added sugar and no sweeteners: different questions
No added sugar describes how a product is formulated. It excludes added monosaccharides and disaccharides, as well as foods used to sweeten the product, such as honey or syrups. Ingredients can still contain their own sugars; in that case, the label must also state that it contains naturally occurring sugars.
No sweeteners answers a separate question: whether additives with that function have been used. A formula can contain very little sugar and use a sweetener to give it a sweet taste. Sugar-free and no sweeteners therefore do not mean the same thing.
A protein powder with stevia still contains a sweetener
Steviol glycosides from stevia, identified as E960a, are sweeteners. EFSA lists them alongside other sweeteners, including sucralose (E955) and acesulfame K (E950). Their plant origin does not change that function.
A phrase such as “no artificial sweeteners” therefore does not confirm that a product contains no sweeteners at all. If you prefer to avoid all of them, check the ingredient list for steviol glycosides too.
You can choose a powder without sweeteners because of its taste or how you want to cook with it. That preference does not require a claim that a formula is healthier simply because of where its ingredients come from.
What to check in the ingredients and nutrition information
Look for sugars, foods used for sweetening and any sweeteners in the ingredient list. Sweeteners can be identified by their name or E number. The “of which sugars” line in the nutrition information tells you the amount of sugars, rather than listing every ingredient that gives a sweet taste.
Also compare the protein per serving and the size of that serving. This helps you assess the amount you will actually use. Unflavoured, no added flavourings and no sweeteners describe different characteristics: check each one for the specific product.
What Glorioso Neutra Bio offers
Glorioso Neutra Bio, in a 600 g pack, combines organic pea, rice, pumpkin and sunflower proteins. Its ingredient list includes guar gum and the DigeZyme® multi-enzyme complex, with no sweeteners or added flavourings.
The published nutrition information declares 0.3 g of sugars per 100 g. These sugars are naturally occurring. This figure applies to Neutra Bio; check the individual composition when choosing another flavour in the range.
Its practical appeal is that you can add it to food without introducing a vanilla, chocolate or strawberry flavour. The plant proteins retain their own taste: unflavoured does not mean tasteless.
Using unflavoured protein without a fixed sweet taste
To make a shake, follow the pack instructions and choose your liquid to suit your preferences. If you use a plant-based drink, check its label too: no added sugar does not guarantee that it contains no sugars.
For porridge or plant-based yoghurt, stir the powder in and adjust the liquid to get the texture you enjoy. You can add cocoa or fruit to suit your recipe, remembering that the finished dish contains the nutrients from all its ingredients.
An unflavoured powder may also suit savoury preparations where a dessert flavour would be out of place. For ideas, explore our vegan protein recipes and choose the variety indicated for each preparation.
Choosing a Glorioso protein
If you want vegan protein with no sweeteners or added flavourings, Neutra Bio matches those criteria. It is a practical option when you prefer to decide the flavour as you make your shake or use the same protein in different recipes.
If you enjoy a defined flavour, compare the options in our vegan protein collection. Check each product's ingredients and nutrition information before choosing, rather than assuming that all varieties share the same attributes.

Questions before buying
Can sugar-free protein contain sucralose?
Yes. The claim refers to sugar content. To check for sucralose, read the ingredient list, where it may appear by name or as E955.
Does sugar-free mean carbohydrate-free?
No. Sugars are part of the carbohydrate figure in the nutrition information. Check both values rather than inferring the total carbohydrate content from a sugar-free claim.
Does unflavoured mean tasteless?
For Neutra Bio, it means that no flavourings have been added. Pea, rice and seed proteins retain their own taste, which you may notice when mixing the powder with water.
Will the shake still be sugar-free if I add fruit?
You cannot establish that from the protein powder alone. You need to consider the sugars and amounts of every ingredient in the preparation, including the fruit and the drink you use.
