What is allulose?
Allulose is a naturally occurring rare sugar derived from plants. It is different from traditional sugar (sucrose) because it is metabolized differently by the body and has little to no effect on blood glucose or insulin levels. That means you get the sweet taste you love without the usual spikes and crashes.
Learn more about what makes allulose different in our informative blog post, Allulose 101: Everything You Need to Know.
Where does just better.® allulose come from?
Allulose is a rare sugar that occurs naturally in some plants, but only in trace amounts. Because it is not widely available in nature, food scientists use a natural enzymatic process to produce allulose from plant-based ingredients. The result is the same rare sugar found in select plants, now available in a consistent form for everyday use.
How is allulose different from sugar?
Allulose differs from traditional sugar in two important ways:
How your body processes it: Traditional sugar (sucrose) is fully absorbed and metabolized, which means it contributes calories and raises blood glucose. Allulose is absorbed but not metabolized for energy, making it nearly calorie-free and having little to no effect on blood sugar or insulin levels.
Sweetness level: Allulose tastes very similar to sugar but is about 70% as sweet.
Learn more about what makes allulose different in our informative blog post, Allulose 101: Everything You Need to Know.
Does allulose taste like sugar?
Yes! Allulose has a clean, sweet taste very close to table sugar, without the bitterness or aftertaste that can come with some alternative sweeteners.
Allulose is about 70% as sweet as regular sugar.
Does just better.® allulose have calories?
Allulose is considered a zero-calorie sweetener. While it technically has a tiny amount of calories per gram, the body doesn’t metabolize it for energy, so it’s counted as zero.
Is just better.® allulose keto-friendly?
Yes. Because it has little to no impact on blood glucose or insulin, allulose is often used in low-carb and keto lifestyles.
Do I count the carbs in allulose?
No. Allulose is not digested like traditional carbohydrates, so it doesn’t count toward net carbs. That’s why you’ll often see it excluded on “net carb” calculations for low-carb or keto eating.
How do you use allulose?
It’s simple—you can use allulose anywhere you’d normally use sugar.
Stir it into coffee or tea, add it to smoothies, sprinkle it over fruit, or use it in your favorite recipes for cookies, cakes, sauces, and more.
Get more insights in our blog: Allulose 101: Everything You Need to Know.
Can I use just better.® allulose in my coffee and tea? In my smoothie? How about on fresh fruit?
Yes! Yes! Yes! It’s a favorite in our mugs, our blenders, and our bowls too! Stir and blend it right in, or sprinkle on top of fruit, and enjoy the sweetness you’ve been craving!
Can I use just better.® allulose and just better.® fiber at the same time?
Yes! You can use just better.® allulose and just better.® fiber together in the same foods and recipes. Allulose provides all the sweetness, while prebiotic fiber supports your gut and helps close the fiber gap in your daily routine.
Sweetness + Fiber = just better.® BFFs. Allulose adds the sweet, and fiber makes it complete.
Is allulose safe for people with diabetes?
Yes. Research shows that allulose has little to no effect on blood glucose or insulin levels, making it suitable for people who need to manage their blood sugar.
[Learn more! Pub Med: Impact of allulose on blood glucose in type 2 diabetes]
If you have diabetes, it’s always best to discuss new foods with your healthcare provider(s) to determine how they fit into your plan.
Does allulose affect blood sugar or insulin levels?
Allulose is absorbed by the body but not metabolized for energy. That means it has little to no impact on blood sugar, does not cause glucose spikes, and does not raise A1C.
How does allulose support balanced blood sugar?
By providing sweetness without the metabolic effects of traditional sugar, allulose helps keep blood sugar steady rather than causing the spikes and crashes that come with traditional table sugar (sucrose). This makes it a smart choice for individuals seeking to manage their carbohydrate intake.
Does allulose improve insulin sensitivity?
Some early research suggests that allulose may have a positive effect on insulin sensitivity; however, further studies are needed to fully understand this benefit.
For now, it’s best to view allulose as a sweetener with little to no effect on blood sugar, while keeping an eye on emerging research.

Does allulose help with weight loss?
Allulose isn’t a weight-loss product, but it can support people who are working toward healthy weight management. Because it provides sweetness with virtually no calories and little to no impact on blood sugar, many people find it a helpful option when they’re looking to reduce sugar and make balanced choices as part of a weight loss journey.
Some small studies have been published suggesting that allulose could be an important part of a weight-loss journey. We're following this research and encourage you to as well. Learn more here: Read more here: The Metabolic and Endocrine Effects of a 12-Week Allulose-Rich Diet.
Is allulose ok for intermittent fasting?
Generally, yes. Allulose does not significantly raise blood glucose or insulin levels, making it an option for many people who practice intermittent fasting.
Will allulose break a fast?
This depends on how strict your fasting routine is. For most people, allulose won’t break a fast in the traditional sense because it’s not metabolized for energy. But if you’re following a very strict, water-only fast, you may prefer to skip it.
Are there any side effects of allulose?
Most people tolerate allulose well. If you do notice digestive changes like bloating or loose stools, it’s often due to the “stacking effect.” That happens when allulose is combined with other alternative sweeteners such as stevia, monk fruit, or sugar alcohols throughout the day. People sometimes mistakenly blame the allulose when it’s actually the stack of sweeteners that adds up.
Does allulose cause bloating or gas?
Not typically. About 70% of the allulose you consume is absorbed in the small intestine but is not metabolized for energy—it simply passes through the body and is excreted in urine. The remaining amount passes through the large intestine and is naturally eliminated. Because allulose moves through the body this way, it doesn’t usually have time to ferment in the gut, making it less likely to cause bloating or gas on its own.
If you do notice digestive discomfort, we’re so glad you’re listening to your body. We encourage everyone to pay attention to how many different sweeteners may be adding up throughout the day. Many people who experience digestive upset also consume other natural or artificial sweeteners across multiple products.
Can I use allulose with other sweeteners?
We do not recommend it. Allulose works best on its own.
When combined with other alternative sweeteners, such as stevia, monk fruit, or sugar alcohols, the “stacking effect” can occur — when multiple sweeteners add up, causing digestive discomfort. To get the best experience, enjoy just better.® allulose without stacking it with other sweeteners.
How much is too much allulose?
Research shows most people tolerate allulose very well in everyday amounts. A single serving of up to about 25–30 grams (roughly 2 tablespoons) is comfortable for most adults, and spread across the day, up to 60 grams is generally well tolerated [Han et al., 2018].
💡 Example: If you bake cookies with just better.® allulose, one cookie may contain about 8 grams. Enjoying a few cookies at once is perfectly fine for most people, but eating a big stack in one sitting could cause mild stomach discomfort, like gas or loose stools.
What makes just better.® allulose different from other sweeteners?
Most sweeteners fall into two camps: either sugar alcohols (which can cause digestive issues) or high-intensity sweeteners (which can have an aftertaste and long-term adverse effects due to their detrimental effects on the gut microbiome).
Allulose stands apart because it is a natural, rare sugar — providing sweetness that’s closer to sugar in taste, with fewer side effects (when used alone) and no lingering flavors.
