The FDA's Official Position: Generally Recognized as Safe (GRAS)
For decades, the U.S. Food and Drug Administration (FDA) has classified erythritol as a substance "Generally Recognized as Safe," or GRAS. This designation indicates that food experts have reviewed available data and concluded that erythritol is safe for its intended use. The FDA doesn't formally approve a substance as GRAS; companies submit a GRAS notification, and the FDA responds with a "no questions" letter if it has no concerns. Multiple GRAS notices for erythritol have received such a response since 2001. This classification allows manufacturers to use erythritol in various foods without the extensive testing required for new food additives.
Key aspects of the FDA's GRAS status for erythritol:
- Long History: The GRAS status relies on a history of safe use or scientific evidence.
- Excretion: Erythritol is mostly absorbed and excreted unchanged, minimizing metabolic impact.
- Oral Health: The FDA acknowledges erythritol's benefit for oral health, as it doesn't cause tooth decay.
The Heart of the Controversy: Recent Cardiovascular Concerns
In early 2023, a study published in Nature Medicine by the Cleveland Clinic raised concerns about erythritol. The study, involving over 4,000 participants, found that those with higher blood erythritol levels had a greater likelihood of experiencing a major adverse cardiovascular event over three years. Further studies suggested erythritol could increase blood platelet reactivity, potentially promoting blood clot formation.
Critical points from the Cleveland Clinic study:
- Patient Demographics: Many participants already had existing cardiovascular risk factors.
- Exaggerated Levels: Consuming 30 grams of erythritol led to significantly elevated blood levels for days in healthy volunteers.
- Association vs. Causation: The study found a correlation, emphasizing the need for further research to confirm direct causation.
The FDA's Response and Ongoing Monitoring
Following the 2023 study, the FDA responded but did not change erythritol's GRAS status. The agency's position is that the observational studies did not establish a causal relationship. The FDA has stated it will continue to monitor new evidence.
The GRAS designation isn't permanent and can be reconsidered if new safety concerns arise. As of late 2024 and early 2025, the FDA has not altered erythritol's classification, though the controversy has increased scrutiny. This highlights the difference between regulatory status and emerging science.
FDA Regulations vs. Industry Practices
How the FDA and Industry Handle GRAS Substances
| Aspect | FDA Role | Industry Role |
|---|---|---|
| Initiation | Evaluates GRAS notices. | Conducts safety assessments and submits notices. |
| Oversight | Responds with "no questions" letters, doesn't formally approve. | Self-affirms GRAS based on expert review. |
| Labeling | Doesn't always require specific labeling, though often listed as sugar alcohol. | Often includes erythritol on labels. |
| Re-evaluation | Can reconsider GRAS status based on new science. | May face pressure based on new studies. |
| Volume Discrepancy | Based initial GRAS on typical consumption. | Uses higher quantities in modern products. |
The distinction is crucial because the FDA's initial assessment of typical intake may not align with the high doses in modern processed foods. This is a key point in the ongoing debate.
Conclusion: Navigating the FDA's Stance and Your Health
The FDA maintains that erythritol is Generally Recognized as Safe (GRAS) based on current evidence. However, the agency acknowledges the need for further research, particularly concerning recent studies linking high blood erythritol levels to potential cardiovascular risk. This situation underscores the difference between regulatory status and evolving scientific understanding.
While erythritol is a low-calorie sugar alternative that doesn't spike blood sugar, individuals with pre-existing cardiovascular risk factors, diabetes, or those consuming large amounts from processed foods may want to be cautious. Consulting a healthcare provider and being aware of total consumption from products like keto ice creams and sugar-free snacks is advisable. The healthiest sources of sweetness remain whole fruits and vegetables, and a whole-foods-based diet is generally recommended.

Understanding the FDA's position on erythritol
- GRAS Designation: The FDA considers erythritol "Generally Recognized as Safe" (GRAS), a status based on a history of safe use or scientific evidence.
- Monitoring New Evidence: Despite the GRAS status, the FDA has stated it will continue to monitor and evaluate new research regarding erythritol's safety.
- Controversial Research: A 2023 Cleveland Clinic study found a correlation between high erythritol blood levels and increased cardiovascular events, raising questions about long-term risks.
- Dosage Discrepancy: The high quantities of erythritol found in modern processed foods often far exceed the levels that the FDA originally evaluated for its GRAS status.
- No Causal Link Confirmed: As of now, the FDA and many researchers emphasize that the recent studies showed a correlation, not conclusive proof of causation, between erythritol and heart problems.
- For High-Risk Individuals: Experts suggest caution for individuals with pre-existing cardiovascular conditions, diabetes, or obesity, who may be more vulnerable to potential risks.
FAQs about the FDA and erythritol
Question: Has the FDA banned erythritol? Answer: No, the FDA has not banned erythritol. The agency still classifies it as "Generally Recognized as Safe" (GRAS) and has continued to issue "no questions" letters regarding manufacturers' safety conclusions.
Question: How did erythritol get its GRAS status from the FDA? Answer: Erythritol was granted GRAS status based on industry submissions dating back to 2001. Food manufacturers and experts concluded it was safe for its intended use, and the FDA has not raised objections to these assessments over time.
Question: Does the FDA require erythritol to be listed on food labels? Answer: As a sugar alcohol, erythritol is often listed under the "Total Carbohydrate" section on a product's nutrition label. However, because it is a GRAS substance, there is no strict requirement for it to be specifically identified as an ingredient in all cases, though many manufacturers do so voluntarily.
Question: What is the FDA's reaction to the cardiovascular risk studies? Answer: The FDA has acknowledged the studies, including the 2023 Cleveland Clinic research, but stated that the observational nature of the studies did not prove a causal relationship. The agency has committed to monitoring new evidence as it becomes available.
Question: Is the FDA likely to change erythritol's GRAS status? Answer: The GRAS status can be re-evaluated at any time if new, compelling scientific evidence emerges. While the FDA is monitoring the situation, no official action has been taken to change its classification based on recent findings, which have shown correlation but not direct causation.
Question: Can I rely on the FDA's GRAS status for erythritol? Answer: The FDA's GRAS status means experts have found erythritol safe for typical consumption based on available evidence. However, recent studies suggest potential risks at very high intake levels, especially for at-risk individuals. It is wise to consider this emerging data and consult a doctor if you have health concerns.
Question: What should high-risk individuals do about erythritol? Answer: The Cleveland Clinic study authors recommend that individuals with pre-existing cardiovascular disease, diabetes, or obesity should consider avoiding or significantly limiting their intake of erythritol until more definitive long-term studies are conducted. Consultation with a healthcare provider is also advised.
