Erythritol

non-nutrient/non-botanical

What is it

Erythritol is a sugar alcohol (polyol) about 70 percent as sweet as sucrose. It is naturally found in small amounts in some fruits and fermented foods, and is commercially produced by yeast fermentation of glucose. It is widely used as a low-calorie sugar substitute.

How it works

Erythritol has a unique metabolic profile among sugar alcohols. About 90 percent of ingested erythritol is absorbed in the small intestine and excreted unchanged in urine within 24 hours. Only the small unabsorbed fraction reaches the colon, where it may be modestly fermented by gut bacteria. Because most erythritol is absorbed and excreted without being metabolized, it provides essentially no calories (about 0.2 kcal/g vs. 4 kcal/g for sugar) and does not raise blood glucose or insulin. The high absorption rate also means erythritol causes less digestive upset than other sugar alcohols (xylitol, sorbitol, mannitol), which reach the colon in larger quantities and cause more gas and diarrhea. In 2023, a study reported that higher blood erythritol levels were associated with increased risk of major cardiovascular events. However, this study did not establish that dietary erythritol caused the elevated blood levels; some erythritol is also produced endogenously through the pentose phosphate pathway, and the association may reflect other metabolic factors. Further research is needed to clarify clinical implications.

AI-assisted evidence assessment — talk to your doctor before relying on any single supplement.

Sugar replacement

Grade A

Strong evidence

Erythritol effectively replaces sugar with approximately 70 percent of sucrose's sweetness, no glycemic impact, and essentially no calories. Widely used in baking and beverages.

Blood glucose control

Grade A

Strong evidence

Erythritol does not raise blood glucose or insulin. Suitable for people with diabetes and those following carbohydrate-restricted diets.

Digestive tolerance

Grade A

Strong evidence

Erythritol has the best digestive tolerance profile among sugar alcohols because most is absorbed and excreted unchanged. Less likely to cause gas and diarrhea than xylitol or sorbitol at equivalent doses.

Dental health

Grade B

Good evidence

Erythritol is not fermented by oral bacteria and may even inhibit Streptococcus mutans growth. Some studies suggest it may help reduce dental caries when replacing sugar.

3 commercial forms

Granulated erythritol

Sugar-like texture; about 70 percent the sweetness of sugar.

Crystalline form similar in appearance and texture to sugar. Can be used 1:1 with adjustment for lower sweetness. May have a cooling sensation in the mouth.

Powdered erythritol

Finer texture; dissolves more quickly.

Like powdered sugar. Useful for frostings and recipes where granular texture is undesired.

Erythritol blends (with stevia, monk fruit)

Bulks high-intensity sweeteners to match sugar volume and sweetness.

Most common consumer form. Examples include Lakanto Monkfruit Sweetener (erythritol + monk fruit) and Truvia (erythritol + stevia). Provides 1:1 sugar substitution by volume and sweetness.

Dosage

There is no required intake; erythritol is used as a sweetener to taste. Typical use ranges from a few grams per serving in beverages to 30 to 50 g daily in some baked goods or sugar replacement diets. The Joint FAO/WHO Expert Committee has not specified a numerical ADI, considering erythritol acceptably safe at typical use levels.

When and how to take it

Erythritol can be used at any time of day. It has no metabolic effects on blood glucose or insulin. It is heat-stable and works in baking. Large single doses may cause minor digestive symptoms; spreading intake across the day reduces this.

Safety

Erythritol is generally well tolerated and has the lowest gastrointestinal side effect profile of any sugar alcohol. High doses (above 50 g per serving) may still cause gas, bloating, or diarrhea in some people. The 2023 association with cardiovascular events has raised questions but no definitive causal relationship has been established.

Who should be cautious

Pregnant and breastfeeding women can use erythritol within typical sweetener amounts. People with very large daily intake or known sensitivity to sugar alcohols may experience digestive symptoms. People with cardiovascular disease or risk factors may wish to be aware of the recent observational research and discuss with their clinician, though no clear recommendation has been made by regulatory bodies. Erythritol is toxic to dogs at high doses; keep away from pets.

Interactions

Erythritol has no significant known drug interactions. It does not affect blood glucose, insulin, or hormone levels at typical sweetener doses. The potential cardiovascular signal in observational data has not translated to specific drug interactions.

Frequently asked questions

Is erythritol safe to consume?⌄

Erythritol has been recognized as safe by regulatory agencies globally. A 2023 study showed an association between blood erythritol levels and cardiovascular events, but did not establish causation from dietary erythritol. Research is ongoing.

Does erythritol cause digestive upset?⌄

Erythritol has the best tolerance of any sugar alcohol because most is absorbed in the small intestine. Some people experience gas or diarrhea with very high doses (over 50 g in a single serving).

Why does erythritol feel cool in the mouth?⌄

Erythritol has a negative heat of dissolution, meaning it absorbs heat as it dissolves on the tongue. This creates a mild cooling sensation, especially in larger amounts or in chewable products.

Can I use erythritol for baking?⌄

Yes, erythritol is heat-stable. It does not caramelize like sugar and may crystallize in some recipes. Blends with monk fruit or stevia for added sweetness are often easier to substitute 1:1 with sugar.

Is erythritol safe for pets?⌄

Erythritol is much less toxic to dogs than xylitol but should not be a routine part of pet diets. At high enough doses, sugar alcohols can cause digestive upset. Keep food sweetened with erythritol away from pets.
