Erütritool (Erythritol): What It Really Is and How Your Body Processes It
Erütritool is the Estonian name for erythritol, a four-carbon sugar alcohol that consumers encounter increasingly on health food labels. It is not artificial chemistry — erythritol occurs naturally in grapes, pears, and even in our own bodies, where it is produced in small quantities during metabolism (Munro et al., 1998).
This guide provides an honest, science-based overview: what erythritol does in the body, the real benefits, and where the limits are.
TL;DR
- Erythritol is absorbed in the small intestine (~90%) and excreted unchanged in urine
- Does not affect blood sugar, insulin, or ketosis
- Digestive tolerance is better than other sugar alcohols (Bernt et al., 1996)
- Safety confirmed by both EFSA and FDA
- The 2023 heart study raised questions but did not prove causation
- Widely available in Estonian supermarkets and online stores
How the Body Processes Erythritol
Erythritol's metabolic pathway is unique among sugar alcohols:
1. Absorption: ~90% is absorbed from the small intestine into the bloodstream
2. Circulation: Circulates in the blood unchanged — the body does not use it as an energy source
3. Excretion: Excreted within 24 hours in urine almost completely unchanged
4. Colon portion: Only ~10% reaches the colon, where it is partially fermented
This is the opposite of other sugar alcohols (xylitol, sorbitol), which are poorly absorbed and reach the colon where bacteria ferment them, producing gas and diarrhea.
Caloric value: is it really zero?
Formally, erythritol's caloric value is 0.2 kcal/g. In EU nutrition labeling, this is often listed as zero since most is excreted unused. Practically, 100g of erythritol contains ~20 kcal — insignificantly little compared to sugar's 400 kcal.
Erythritol and Blood Sugar
Clinical studies confirm that erythritol does not raise blood glucose levels or stimulate insulin secretion (Ishikawa et al., 1996). This makes erythritol one of the safest sweeteners for:
- Type 2 diabetics — does not disrupt blood sugar control
- Keto dieters — does not affect ketosis
- Insulin-resistant individuals — does not burden the pancreas

Erythritol in Estonia
Where to Buy
Erythritol is well available in Estonia:
- Prisma, Selver, Rimi — on the health foods shelf
- Biomarket — organic specialty store
- Online stores — MaxFit.ee and others
Price Range
Erythritol prices in Estonia typically fall between €8-15 per kilogram, more expensive than sugar (~€1/kg) but cheaper than stevia.
In Products
Check the ingredients of healthy sweets sold in Estonian stores — more and more use erythritol:
- Protein bars
- Zero-calorie drinks
- Healthy chocolates
- Sweetened versions of protein powders
Erythritol vs Stevia
These are the two most popular zero-calorie sweeteners. How do they differ?
| Property | Erythritol | Stevia |
|---|---|---|
| Origin | Fermented from starch | From stevia plant |
| Taste | Clean, slight cooling effect | Bitter aftertaste |
| Sweetness | 60-70% of sugar | 200-300x sweeter |
| Usage | Direct replacement | In small quantities |
| Price | Moderate | High |
| Baking | Good bulk | No bulk |
Best solution: Use them together. Erythritol provides bulk and texture, stevia adds sweetness. A 4:1 ratio (erythritol:stevia) gives the best results.
Safety and Regulation
- EFSA (European Food Safety Authority): confirmed safe
- FDA (USA): GRAS (Generally Recognized As Safe) status since 2001
- Estonian Health Board: permitted as food additive without restrictions
No ADI (Acceptable Daily Intake) has been set for erythritol because it is so well tolerated that a limit is unnecessary. However, a sensible guideline is up to 1g per kilogram of body weight per day (Munro et al., 1998).
Common Mistakes
1. Confusing with other sugar alcohols — Erythritol and xylitol are different substances. Xylitol contains 2.4 kcal/g, erythritol 0.2 kcal/g.
2. Overemphasizing the 2023 study — One correlation study with already-ill patients is not sufficient reason to avoid a safe product.
3. Expecting too much — Erythritol is not a miracle solution. It is simply a better alternative to sugar.
FAQ
Is erythritol GMO?
The raw material (corn or wheat starch) may be GMO, but the fermentation process removes all genetic material. Non-GMO erythritol can be found in organic stores.
Is erythritol safe during pregnancy?
Current evidence suggests safety, but always consult your doctor before using any supplement during pregnancy.
Is erythritol the same as xylitol?
No. Both are sugar alcohols, but they differ in caloric value, sweetness, and digestive tolerance. Erythritol has virtually zero calories; xylitol has 2.4 kcal/g.
Why does erythritol cause a cooling sensation?
It is an endothermic reaction — erythritol absorbs heat when dissolving, creating a cooling sensation. This is a physical property, not a chemical additive.
