What Is Allulose?

Quick Answer

Allulose is a naturally occurring “rare sugar” that tastes like sugar but has minimal impact on blood glucose levels. Unlike regular sugar, allulose is absorbed by the body but is not significantly metabolized for energy, resulting in little to no increase in blood sugar or insulin.


Definition: Allulose

Allulose is a low-calorie sugar found in small amounts in foods like figs and raisins. It provides the taste and texture of sugar but contributes almost no usable energy to the body and has a near-zero glycemic impact.


How Allulose Affects Blood Sugar

One of the key benefits of allulose is its effect on blood glucose.

Unlike sugar:

  • it is absorbed in the small intestine
  • it is not significantly metabolized
  • it is excreted largely unchanged

Because of this, studies show that allulose produces minimal to no increase in blood glucose or insulin levels.

This makes it a popular option for people who are:

  • managing blood sugar
  • following low-carb or keto diets
  • looking to reduce sugar intake

How Allulose Compares to Sugar

Feature Sugar Allulose
Calories 4 kcal/g ~0.2–0.4 kcal/g
Glycemic Impact High Minimal
Taste Sweet ~70% as sweet as sugar
Blood Sugar Effect Raises glucose Minimal impact
Insulin Response Yes Minimal

Allulose behaves similarly to sugar in cooking and candy-making, which makes it especially useful for products that require texture, bulk, and caramelization.


Allulose vs Other Sweeteners

Many sugar alternatives exist, but they behave very differently.

Sweetener Glycemic Impact Notes
Stevia None Very sweet, can have aftertaste
Monk Fruit None Often blended with erythritol
Erythritol Minimal Cooling effect, can cause digestive issues
Maltitol Moderate Can raise blood sugar
Allulose Minimal Closest to sugar in taste and function

Allulose stands out because it combines:

  • low glycemic impact
  • sugar-like taste
  • real functionality in food

Is Allulose Safe?

Allulose is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration.

It has been studied for:

  • metabolic effects
  • digestion
  • long-term safety

Most research shows it is well tolerated when consumed in typical dietary amounts.

As with any ingredient, individuals should consider their own dietary needs and consult healthcare professionals when necessary.


Why Allulose Is Used in Candy

Most sugar alternatives struggle to replicate the texture of real candy.

Allulose is different because it:

  • browns like sugar
  • dissolves like sugar
  • provides bulk and structure

This makes it possible to create candy that:

  • tastes like traditional candy
  • avoids sugar
  • has minimal glycemic impact

Candy Made with Allulose

A growing number of products now use allulose instead of sugar.

Of course, one example is SWITCH®, a candy brand that formulates gummies, caramels, pancake syrup and other sweets using allulose rather than sugar or high-glycemic sweeteners.

Because allulose behaves similarly to sugar, it allows candy to maintain a more traditional taste and texture compared with many alternative sweeteners.

Is allulose better than sugar?

Allulose provides similar taste and functionality to sugar but with significantly fewer calories and minimal glycemic impact.


Is allulose keto-friendly?

Yes, allulose is commonly used in keto-friendly products because it does not significantly affect blood glucose or insulin levels.


Why isn’t allulose used everywhere?

Allulose is more expensive than sugar and is still gaining adoption in large-scale food manufacturing.
