What is allulose?

Allulose is a type of sugar that resembles fructose, which is the sugar that occurs naturally in fruit.

It is available in a granulated form and looks like everyday sugar. The scientific name for sugar is sucrose. Allulose is a low calorie sweetener that has 70% of the sweetness of sucrose.

According to the Food and Drug Administration (FDA), allulose provides about 0.4 calories per gram (g)Trusted Source, which is significantly lower than the 4 calories per g in sugar. In addition, the body absorbs allulose but does not metabolize it into glucose, so it is virtually calorie free. According to the FDA, allulose has little to no effect on blood glucose or insulin levels.

Scientists can produce allulose in the laboratory, but it is also found naturally in some foods, such as dried fruits, brown sugar, and maple syrup.

Other names for allulose include psicose, d-psicose, d-allulose, or pseudo-fructose.

What is allulose made from

What is allulose made from

Allulose, a monosaccharide also known as psicose, is a rare sugar. It’s found naturally in dried fruits like jackfruit, figs and raisins, but only in small quantities which makes it difficult to extract from its original source. Allulose is about 70% as sweet as sucrose, tastes just like it and even has the same chemical formula (albeit the hydrogen and oxygen atoms are arranged differently). Gram for gram, allulose has approximately 90% fewer calories than sucrose. It’s somewhat hard to find in food products at the moment, but that may change in the future. Scientists have recently discovered ways to produce allulose on a larger scale, making it available as a food ingredient.

What is allulose sweetener

Allulose is a new sweetener on the market. It supposedly has the taste and texture of sugar, yet contains minimal calories and carbs. In addition, early studies suggest it may provide some health benefits.

However, as with any sugar substitute, there may be concerns about its safety and health effects with long-term use.

What is allulose powder

Allulose is a natural powdered sugar without the sugar spike. This keto powdered sugar replacement tastes, bakes, browns, and dissolves just like powdered sugar does. Besti natural sweetener has zero calories, zero net carbs, and zero glycemic index.

What is allulose made out of

What is allulose made out of

Allulose is one of many different sugars that exists in nature in very small quantities. It was initially identified from wheat and has since been found in certain fruits including jackfruit, figs and raisins.

Allulose is naturally present in small quantities in a variety of sweet foods like caramel sauce, maple syrup and brown sugar.

What is allulose used for

People use allulose as a sugar substitute. People with diabetes and obesity can benefit from this sugar substitute because it is low in calories and has little effect on blood sugar.

What is allulose glycemic index

Allulose has no impact on blood glucose

In conducting studies as part of the GRAS process, researchers found that the non-nutritive sweetener allulose has no impact on blood glucose and actually suppresses glycemic response of other glycemic carbohydrates when tested with carbohydrates or within a meal. When tested as a single ingredient, allulose is shown to be non-glycemic.

Three studies highlighted below used various scientific models and found the same conclusion — allulose does not impact blood sugar:

In a crossover study with 20 healthy adults after an overnight fast, 7.5 g of allulose intake did not influence blood glucose or insulin concentration; 5 and 7.5 g of allulose intake suppressed glycemic response (postprandial blood glucose) and insulinemic response (postprandial insulin) of 75 g of co-ingested maltodextrin [6].6. Iida T, Kishimoto Y, Yoshikawa Y, Hayashi N, Okuma K, Tohi M, Yagi K, Matsuo T, Izumori K. Acute D-psicose administration decreases the glycemic responses to an oral maltodextrin tolerance test in normal adults. J Nutr Sci Vitaminol (Tokyo) 2008; 54:511-514.

Another clinical study tested 5 g allulose in tea with a standard meal after an overnight fast in 15 adults diagnosed with borderline diabetes and 11 adults with normal glycemia. This treatment suppressed glycemic response (postprandial glucose) but not insulinemic response (postprandial insulin) of the standard meal in subjects with normal glycemia and in those with borderline diabetes compared to a meal without allulose [7].7.

Study on the postprandial blood glucose suppression effect of D-psicose in borderline diabetes and the safety of long-term ingestion by normal human subjects. Biosci Biotechnol Biochem 2010; 74:510-519.

In another human pilot study supported by Tate & Lyle, an allulose manufacturer, ten healthy adults were given 25 g allulose or 25 g glucose in a cross-over design after a 12 to 14 hour fast. Results showed that when subjects consumed allulose, blood glucose response did not rise above baseline for two hours following the dose. [8]8. Kendall C, Wolever T, Jenkins A et al.

What is allulose found in

What is allulose found in

Allulose was first identified in the leaves of wheat in the 1940s and has since been found in small quantities in certain fruits including figs and raisins, as well as in maple syrup.

Unlike regular sugar (sucrose), it has no impact on blood glucose or insulin levels, making it an ideal alternative for those with, or at risk of, type 2 diabetes. It is also virtually calorie free, with just 10% of the calories of sugar, making it a great tool for weight management.

allulose substitute

Allulose is a type of sugar that is found naturally in certain foods. Other sugar substitutes that people use include: stevia. aspartame.

allulose vs erythritol

It is sweeter than erythritol but still less sweet than table sugar. ... Unlike sugar alcohols, Allulose does pass through the gut wall but it's still not metabolized by your body. Allulose has 0.4 calories per gram which isn't nothing, but it is about 1/10th the amount you would get from table sugar!


Allulose side effects

According to the FDA, people may experience some abdominal discomfort from consuming large quantities of allulose, but this side effect is not toxic and usually temporary.

In one study, researchers investigated the possible side effects of consuming allulose occasionally or regularly. People reported abdominal side effects when consuming increasing doses of allulose, including:


abdominal pain


decreased appetite

passing gas

abdominal sounds

Is allulose an artificial sweetener

Is Allulose an Artificial Sweetener? No. allulose is classified as a “rare sugar,” because it's naturally found in small amounts in a few foods—including figs, raisins, molasses, and maple syrup. Like glucose and fructose—the two components that make up sucrose, or table sugar,—it's a "monosaccharide," or simple sugar.

How safe is allulose?

Allulose appears safe and is unlikely to cause health problems when consumed in moderation. However, as with any food, individual sensitivities are always a possibility. Summary: Animal studies using extremely high doses of allulose for up to 18 months found no signs of toxicity or side effects.

Is allulose the same as stevia?

Allulose is a natural sweetener that seems like it could easily substitute for sugar in food and beverage products. Unlike stevia, monk fruit and erythritol, allulose is an actual sugar that is chemically similar to table sugar. It has a similar taste and texture, as well as the same browning properties as sugar.

Is allulose a sugar alcohol?

Allulose is a natural low calorie sweetener derived from sources like dates and figs with the same taste and texture as table sugar. The FDA has labeled it a “rare sugar” so just to clarify: Allulose is NOT a sugar alcohol! It lives in a class of its own because it is actually a sugar. Cool thing: it has a unique nutritional profile as it shares a typical chemical structure of a carbohydrate but only contributes a fraction of the calories (1/10th of the calories of regular sugar) and doesn’t raise blood sugar levels.
