Clarifying Concerns About Erythritol and Xylitol
Clarifying Concerns About Erythritol, Stroke, and Heart Attack
Recent headlines linking erythritol to stroke and heart attack have sparked unnecessary alarm. However, a closer look at the study behind these claims reveals significant misinterpretations.
Understanding the Facts
A 2023 study published in Nature Medicine suggested a correlation between high erythritol blood levels and cardiovascular events. However, this does not mean that consuming erythritol causes heart attacks or strokes. Key points from the research include:
-
Erythritol Blood Levels vs. Erythritol Consumption
The study focused on naturally occurring erythritol in the blood, not direct consumption from food products (Witkowski et al., 2023). The human body produces erythritol as a byproduct of glucose metabolism, especially in people with conditions like diabetes (Nishimura et al., 1992). -
Association, Not Causation
The study observed correlations but did not establish that consuming erythritol leads to heart disease (Witkowski et al., 2023). Many factors, such as diet and underlying health conditions, were not accounted for in the analysis. -
Data Collection Predates Widespread Erythritol Use
The study examined data from 4,139 participants, including 2,149 from the U.S. Many of these participants were studied before erythritol became a common sugar substitute, meaning their erythritol levels were from internal production rather than dietary intake. -
Study Participants Had Preexisting Conditions
The individuals studied were already undergoing cardiac assessments, meaning they had an elevated risk of cardiovascular events. The findings may not be applicable to individuals with normal cardiovascular health.
What This Means for Zolli Candy
Zolli Candy products contain less than 1/30th of a percent of erythritol, making them an extremely low source of this sugar alternative. For comparison, a single serving of many keto-friendly or sugar-free products contains multiple grams of erythritol, significantly more than what is found in Zolli Candy. Given the study’s focus on naturally occurring erythritol in at-risk individuals rather than dietary intake, its conclusions should not be applied to Zolli’s products.
Headlines exaggerating the risks of erythritol have caused unnecessary confusion for consumers seeking healthier alternatives. As always, it’s essential to rely on well-rounded research and consult healthcare professionals when making dietary choices.

Clarifying Concerns About Xylitol and Health Risks
Recent concerns about xylitol, particularly its effects on health, have led to confusion among consumers. However, the existing research does not support claims that xylitol poses significant health risks for humans when consumed in normal amounts.
Understanding the Facts
Xylitol is a naturally occurring sugar alcohol found in many fruits and vegetables and is commonly used as a sugar substitute in dental-friendly and sugar-free products. Some misleading concerns have arisen, so let’s clarify the facts:
-
Xylitol and Cardiovascular Health
Unlike erythritol, there is no research linking xylitol to an increased risk of heart attack or stroke. In fact, some studies suggest xylitol may have potential metabolic benefits, such as improving insulin sensitivity and reducing oxidative stress (Mäkinen, 2016). -
Xylitol Is Beneficial for Oral Health
Xylitol has been widely studied for its positive effects on dental health. It reduces harmful bacteria in the mouth, helps prevent cavities, and promotes saliva production, which can alleviate dry mouth (Söderling, 2009). This is one reason why xylitol is included in Zolli Candy products—to support oral health while providing a delicious, sugar-free treat. -
Xylitol and Digestive Tolerance
Some people may experience mild digestive discomfort if they consume xylitol in excessive amounts, as it can have a laxative effect (Livesey, 2003). However, Zolli Candy uses xylitol in small, well-tolerated quantities, making it unlikely to cause digestive issues when consumed as part of a balanced diet. -
Xylitol Is Toxic to Dogs but Safe for Humans
One of the most well-known concerns about xylitol is its toxicity to dogs. While even small amounts can cause severe reactions in dogs, xylitol is completely safe for human consumption and is even recommended by dental professionals for its cavity-fighting properties. Pet owners should always keep xylitol-containing products out of reach of their pets (Jensen et al., 2018).
What This Means for Zolli Candy
Zolli Candy includes xylitol in our drops and gum pops as an ingredient to help clean teeth and prevent cavities, aligning with our mission to create healthier, sugar-free treats. The amount used in Zolli Candy is below the levels that might cause digestive issues, and its benefits for oral health are well-documented.
As with any food ingredient, it’s important to separate scientific facts from sensationalized headlines. Xylitol has been extensively studied and found to be a safe, effective sugar alternative that supports dental and metabolic health.
