New low calorie sweeteners appear on the market at a rate almost too fast to keep up with.

One of the newer types is Swerve Sweetener, a calorie-free sugar replacement made from natural ingredients.

This article discusses what Swerve is and some of its potential benefits and drawbacks.

What is Swerve sweetener?

Swerve is advertised as “the ultimate sugar replacement” (1).

It doesn’t have any calories or net carbs. Plus, it is certified non-GMO and doesn’t raise your blood sugar levels.

Swerve bakes, tastes, and measures cup-for-cup like regular sugar. It comes in granular and confectioners’ sugar forms, as well as in individual packets.

Unlike artificial sweeteners, such as aspartame, saccharin, and sucralose, Swerve Sweetener is made from natural ingredients, and all ingredients are sourced from the United States and France.

Furthermore, unlike natural sweeteners such as stevia and monk fruit, Swerve is ideal for baking, as it caramelizes and holds its shape like sugar.

Swerve Sweetener is a sugar substitute that has zero calories and does not raise your blood sugar. It’s made from natural ingredients and can be used for baking.

What is it made from?

Swerve Sweetener is made from three ingredients: erythritol, oligosaccharides, and natural flavor.

First, erythritol is made by fermenting glucose with a microorganism in brewery tanks, similarly to how beer and wine are made.

Then, enzymes are added to starchy root vegetables to break down their starch, resulting in oligosaccharides.

Finally, natural flavors are added to replicate the taste of table sugar.

Here’s a closer look at these ingredients.

Erythritol

Erythritol is a type of sugar alcohol like xylitol, mannitol, and sorbitol.

It’s found naturally in small amounts in some fruits and vegetables. However, the erythritol in Swerve Sweetener is created by fermenting glucose from non-GMO corn with Moniliella pollinis, a yeast-like fungus (1).

Erythritol has 60–80% of the sweetness of sugar, with only 0.2 calories per gram compared with 4 calories per gram in table sugar (2).

Oligosaccharides

Oligosaccharides are sweet-tasting carbohydrates composed of short chains of sugars. They’re found naturally in fruits and starchy vegetables (3).

The oligosaccharides in Swerve Sweetener are made by adding enzymes to starchy root vegetables. The company that makes Swerve does not reveal which vegetables or enzymes are used in this process (1).

Oligosaccharides can comprise the simple sugars fructose or galactose, but it’s unknown which of these types Swerve contains.

Because oligosaccharides are prebiotic fibers that cannot be broken down by the human digestive tract, they’re considered calorie-free (3).

Instead, they pass intact through your digestive system into your colon, where they support the growth of healthy bacteria (3).

Natural flavors

Natural flavors are substances that manufacturers add to products to improve their taste.

However, the term “natural” can be misleading.

The Food and Drug Administration (FDA) defines natural flavors as substances extracted from edible plant and animal parts, as well as those produced using yeast or enzymes (4).

Many natural flavors are created in laboratories by food chemists using natural sources.

According to the Swerve website, the sweetener is made using “a little natural flavor from citrus,” and it contains no animal products (1).

Swerve Sweetener is made from erythritol, oligosaccharides, and natural flavors. According to the company, it contains erythritol sourced from non-GMO corn, oligosaccharides from root vegetables, and citrus-based natural flavors.

Benefits of Swerve sweetener

Because the human body cannot digest the ingredients in Swerve, the sweetener contains zero calories and does not raise blood sugar or insulin levels.

As explained above, erythritol cannot be broken down by your body. Therefore, though it contains 0.2 calories per gram, Swerve can be labeled as a calorie-free food (2).

Studies have shown that erythritol does not raise blood sugar or insulin levels (5, 6).

Oligosaccharides contribute 4 grams of carbs per teaspoon of Swerve. However, because they cannot be digested by the human body, these carbs don’t contribute to the total calories.

Studies have also shown that oligosaccharides don’t cause an increase in blood sugar or insulin levels (7).

Because your body cannot digest the carbs in Swerve Sweetener, it’s calorie-free and does not raise blood sugar or insulin levels.

Potential drawbacks

Erythritol and oligosaccharides, the two main ingredients in Swerve, have been associated with digestive upset.

Erythritol is a sugar alcohol, and both erythritol and oligosaccharides are high in Fermentable Oligo-, Di-, Mono-saccharides and Polyols (FODMAPS), which are short-chain carbs that are fermented by bacteria in your gut.

Sugar alcohols may cause digestive issues

Because your body cannot digest sugar alcohols, they travel through your digestive tract unchanged until they reach your colon.

There, they’re fermented by bacteria, which can lead to gas, bloating, and diarrhea.

However, studies have suggested that erythritol may have less of an effect on your digestion than other sugar alcohols.

Unlike other sugar alcohols, about 90% of erythritol is absorbed into your bloodstream. Thus, only 10% makes it to your colon to be fermented (8).

Additionally, erythritol seems to be more resistant to fermentation, compared with other sugar alcohols (8).

In fact, studies have shown that erythritol in doses up to 0.45 grams per pound (1 gram per kg) of body weight is well tolerated (9, 10).

Yet, other studies have shown that a single dose of 50 grams of erythritol was linked to nausea, and 75 grams of erythritol was associated with bloating and diarrhea in 60% of people (11, 12).

High in FODMAPs

Oligosaccharides are considered high FODMAP foods. FODMAPs are short-chain carbs that can cause digestive issues for some people when fermented by gut bacteria.

A diet high in FODMAPs has been shown to cause abdominal pain and bloating in people with irritable bowel syndrome (IBS) (13).

However, it’s debated whether erythritol should be considered high FODMAP. Monash University, the creators of the low FODMAP diet, state that erythritol may not have the same effect as other sugar alcohols because it’s more difficult for digestive bacteria to break down (14).

More research is needed to determine whether erythritol is problematic for people with IBS.

May increase fructose malabsorption

Some studies suggest that erythritol, when combined with fructose, interferes with the absorption of fructose in the digestive system (15).

Malabsorption of fructose is linked to irritable bowel syndrome (16).

All things considered, you may want to steer clear of Swerve and other natural sweeteners if you’re prone to digestive symptoms.

However, as long as you don’t eat high amounts of Swerve at a time, it’s unlikely to cause symptoms. Individual tolerance to the ingredients in Swerve may vary.

Swerve contains erythritol and oligosaccharides, both of which are high in FODMAPS, which can cause digestive issues. When consumed in small amounts, Swerve is unlikely to cause these problems.

The bottom line

Swerve Sweetener is a sugar replacement made from the natural ingredients erythritol, oligosaccharides, and natural flavors. Although, it’s unknown what exact sources the manufacturer uses to make the latter.

It’s calorie-free and doesn’t raise blood sugar or insulin levels, but high amounts may cause digestive upset.

If you like the taste and don’t experience digestive symptoms when consuming Swerve, it appears to be safe in low to moderate amounts.
