Comparison
Dextrose vs Maltodextrin
The short answer
Dextrose is glucose, so it tastes sweet. Maltodextrin is the same kind of starch broken only partway, so it barely tastes sweet and mostly adds bulk. Both are gluten-free, and neither fits a keto diet.| Side by side | Dextrose (Glucose) | Maltodextrin |
|---|---|---|
| Safety score | 60/100 Use in moderation | 62/100 Use in moderation |
| What it is | One glucose sugar | Short chains of glucose |
| Taste | Sweet | Almost no sweetness |
| Usual job | Sweetener | Filler and carrier |
| Keto | No | No |
| Gluten-free | Yes | Yes |
Swapping one for the other
Use dextrose when the recipe needs sweetness. Use maltodextrin when a powder needs body without much taste. They are not a one-for-one sugar swap.
Common questions
Is dextrose better than maltodextrin?
Neither one is a health upgrade. Both come from starch and both are glucose your body can use. Dextrose is just the fully broken-down, sweet kind.
