If you’re following a low-sugar or keto lifestyle, you’ve probably seen erythritol on the label of everything from protein bars to flavored drinks. It’s one of the most common sugar substitutes in “zero sugar” and low-carb foods — but recent studies suggest it might be time to take a closer look.
What the Research Says
Erythritol is a sugar alcohol that occurs naturally in small amounts in some fruits and fermented foods. It’s widely used as a low-calorie sweetener because it doesn’t raise blood sugar or insulin levels.
But new research published in Nature Medicine and PNAS Nexus has raised potential concerns:
- Elevated erythritol levels in the blood were linked to a higher risk of cardiovascular events like stroke and heart attack.
- Erythritol may make blood platelets more likely to stick together, increasing the chance of clots.
- Animal models suggest it could affect the blood-brain barrier, though human data is still limited.
These findings are associations, not proof of harm. Still, they suggest the need for caution — especially in people with cardiovascular risk factors.
Where Is Erythritol Found?
You’ll find erythritol in a wide range of products marketed as sugar-free or keto-friendly:
- Baked goods and snack bars
- Sugar-free candy and gum
- Electrolyte mixes and flavored waters
- “Zero sugar” sodas
- Some oral care products (like toothpaste or mouthwash)
Because it’s less sweet than table sugar, manufacturers often use large quantities to achieve the desired flavor — making it easy to consume more than you realize.
How to Use Erythritol Safely
You don’t have to eliminate erythritol completely. But moderation matters — especially if you’re using several sugar-free products daily. Here’s what to consider:
- Read ingredient labels carefully on low-carb and keto foods.
- Limit total daily intake by rotating in unsweetened or naturally sweet alternatives.
- Choose whole foods like fruit, cinnamon, or a small amount of honey when possible.
- If you have heart disease, clotting disorders, or metabolic concerns, talk with a qualified provider.

FAQ: Erythritol and Health
Is erythritol safe in small amounts? Yes, occasional use appears safe for most people. However, large daily doses may not be ideal for those with heart or clotting risks.
Does erythritol spike blood sugar? No. It’s known for having a zero glycemic index and doesn’t raise insulin levels.
Is erythritol natural or artificial? It occurs naturally in small amounts, but most erythritol used in food products is manufactured from corn or sugar.
What’s a better alternative to erythritol? Depending on your needs, options include fruit, honey, stevia, or monk fruit in moderation.
Should I avoid all sugar substitutes? Not necessarily. But if you’re using multiple products with sugar alcohols daily, it’s smart to discuss with your provider.
