Erythritol Got a New EU Intake Limit in 2023. The US Still Has None.

Published October 3, 2026

In December 2023, European food regulators did something for erythritol that American regulators never have. They put a precise number on how much of the sweetener a person can eat in a day. The number is 0.5 grams per kilogram of body weight. By the European Food Safety Authority's own math, nearly everyone who eats erythritol-sweetened food already goes over it.

What Just Happened

On December 20, 2023, the European Food Safety Authority (EFSA), the EU's scientific food-evaluation body, published its re-evaluation of erythritol, the sugar alcohol sold under names like Zerose and listed on ingredient panels as E 968 (EFSA Journal 2023;21(12):8430). For the first time, the opinion set an acceptable daily intake, or ADI, for erythritol: 0.5 grams per kilogram of body weight per day. EFSA based that figure on the lowest dose, in human studies, at which nobody developed diarrhea, the sugar alcohol's defining digestive effect. EFSA was blunt about what the number means in practice. Its plain-language summary states that "both acute and chronic exposure to erythritol is above the newly set ADI" across every population group it examined, and that people who eat a lot of erythritol-sweetened food may notice the laxative effect after a single serving or with repeated use. The panel also reviewed erythritol's manufacturing process, found no evidence that the additive is genotoxic, identified lead as the only impurity of concern, and recommended lowering the current maximum lead limit from 0.5 milligrams per kilogram. On the question of heart health, EFSA did not find a cause-and-effect link in the evidence it reviewed, while saying further research could help settle open questions. The file isn't closed. EFSA opened a formal call in 2026 for new analytical and use-level data on erythritol, with submissions due by June 30, 2026, and a refreshed exposure assessment scheduled to start in early 2027.

How We Got Here

Erythritol's path through U.S. regulation has run almost entirely outside formal rulemaking. In March 1997, three manufacturers, Cerestar Holding, Mitsubishi Chemical, and Nikken Chemicals, filed a petition asking the FDA to formally affirm erythritol as Generally Recognized as Safe, the legal designation known as GRAS (62 Fed. Reg. 10285, Docket No. 97G-0063). That petition never became a final regulation. The FDA soon moved away from the GRAS affirmation petition process in favor of a newer GRAS notification system, and erythritol has only ever reached U.S. shelves through that newer route: a company notifies the FDA of its own conclusion that an ingredient is GRAS, and the agency responds that it has "no questions at this time." Cargill received such a letter in 2019 for erythritol made by fermenting glucose with the yeast Moniliella pollinis (FDA GRN 000789). A separate manufacturer, Shandong Starlight So True Biological Technology, received a similar letter as recently as April 7, 2026, for erythritol fermented with a different organism, Yarrowia lipolytica, cleared for use levels as high as 100 percent in sugar substitutes (FDA GRN 001296). Erythritol has no entry of its own in 21 CFR Part 184, the FDA's list of additives formally affirmed GRAS by regulation; it has simply never gone through that process. The scientific scrutiny sharpened in February 2023, before EFSA's opinion was finalized, when a Cleveland Clinic team led by Dr. Stanley Hazen published a study in Nature Medicine. Tracking more than 1,000 people and then replicating the finding in two additional groups totaling nearly 3,000 people, the researchers reported that participants in the top quarter of blood erythritol levels had roughly twice the rate of major adverse cardiovascular events, meaning death, heart attack, or stroke, over three years, compared with those in the bottom quarter. Laboratory work on human platelets and mice, plus a small trial giving eight volunteers an erythritol-sweetened drink, pointed to a possible mechanism: erythritol encouraging clot formation. The researchers and the National Institutes of Health, which later summarized the work, were careful to frame it as an association rather than proof; NIH's own write-up states the connection "hasn't yet been proven" and calls for further study. EFSA's subsequent opinion considered this literature and reached no cause-and-effect conclusion on it, even as it tightened its own number on separate, digestive grounds.

Where Regulators Diverge

The regulatory picture runs in more than one direction, which is the useful part. The Codex Alimentarius system, through the Joint FAO/WHO Expert Committee on Food Additives, evaluated erythritol back in 1999 and listed its ADI as "not specified," the designation JECFA uses when a substance's intake at normal use levels doesn't warrant a numeric cap. EFSA's 2023 opinion effectively reversed that posture for the European market, replacing "not specified" with an actual gram-per-kilogram figure, specifically because of digestive tolerance data, not a new finding about the substance's underlying chemistry. The United States has matched neither position with a number of its own. FDA regulation does require a laxative-warning statement for some other sugar alcohols once intake crosses a defined threshold, such as 50 grams of sorbitol per day under 21 CFR 184.1835(e), but no equivalent numeric trigger exists for erythritol. Health Canada's List of Permitted Sweeteners authorizes erythritol with maximum use levels set category by category, but, like the U.S., states no daily-intake ceiling on that list. None of this means erythritol is banned anywhere. It remains on sale, unrestricted by dose, in the EU, Canada, and the U.S. alike. What changed is that one regulator, the EU's, is now the only one in this group to have published a specific number, and by its own estimate, ordinary eating already runs past it.

What the Label Actually Says

On a U.S. ingredient list, erythritol appears by its own name, sometimes alongside a brand name like Zerose or Sukrin. Federal law doesn't require it to carry a laxative-effect statement or a grams-per-serving disclosure the way sorbitol and mannitol do. It can, however, appear next to a specific FDA-authorized claim: since a December 1997 final rule added it to the sugar alcohols eligible for the tooth-decay health claim (62 Fed. Reg. 63653, Docket No. 97P-0206; 21 CFR 101.80), a package can state that erythritol, unlike sugar, does not promote dental cavities. There is no U.S. label requirement tied to EFSA's 0.5-gram-per-kilogram figure, and no American product will show it. A shopper who wants to check their own intake against it has to do the arithmetic themselves: for a 70-kilogram (154-pound) adult, the EFSA threshold works out to about 35 grams of erythritol a day. Packages don't give a per-gram erythritol count the way they do for added sugar, so there is currently no label-based way for a U.S. shopper to run that comparison product by product.

Where PurityIQ Fits

This is the kind of gap PurityIQ exists to close at the shelf: a number one regulator has published, a number international and U.S. authorities have declined to adopt, and a label that gives shoppers no way to check a product against either one. The app puts that record in front of you while you're holding the product, cited to EFSA's own opinion and the FDA's own GRAS letters, with no score and no verdict attached. You see the record.
