10 Things to Consider When Buying Sweetener Sorbitol Crystal 20 60 wholesale

Sugar alcohols, also known as polyols, are neither sugars nor alcohols — they're actually sugar-free.

Like table sugar, polyols are carbohydrates, but they provide fewer calories because they resist digestion to varying degrees. Some are slowly absorbed, others only partially metabolized, and one passes through the body mostly intact.​​

​

From chemistry class, polyol means "containing many -OH groups" (hydroxyl or alcohol group). This explains why polyols' names end in -ol, such as in sorbitol, xylitol, mannitol, maltitol, and isomaltitol.   

Sugar alcohols are ideal for reducing sugar while maintaining a sugar-like texture in your recipes. As bulk sweeteners, they do more than just add sweetness—they also contribute weight and volume, much like sugar.  This sets them apart from bulk-free sweeteners, which are highly concentrated and used solely for sweetness.

The most widely used polyols in sugar substitutes include:
 

1. Erythritol

2. Xylitol

3. Sorbitol

4. Mannitol

5. Isomalt

​​​​

How sweet are polyols?

Except for xylitol, which matches sugar in sweetness, most polyols are only mildly sweet. So, manufacturers often blend them with high-intensity sweeteners such as stevia, monk fruit, or sucralose.​ 

​

Are polyols natural or artificial sweeteners?

The FDA defines natural ingredients as those that exist in nature AND are derived from natural materials. However, it acknowledges that some ingredients that exist in very small amounts in nature must be "manufactured artificially" to be produced in large scale. The FDA still considers these “natural”, but for clarity, here at WhatSugar we refer to them as synthetic.

​

To explain this, the FDA uses vitamin C (ascorbic acid) as an example. It can be derived from an orange or artificially produced via fermentation, but the final ingredient is identical. The same applies to some polyols like erythritol, which naturally occurs in some foods but only in minuscule amounts. So, it's commercially produced through fermentation from corn.

​

Note that synthetic is not the same as artificial. Vitamin C made via fermentation would not be considered artificial as it’s indistinguishable from the vitamin C found naturally in fruits. Learn more about natural vs synthetic vs artificial HERE and HERE.

​

Not all polyols are found in nature, but all are synthetically made from sugars:

• Natural polyols (per FDA definition) include erythritol, sorbitol, xylitol, and mannitol because they're found in nature AND derived from a natural source. These can legally be labeled as “natural,” though at WhatSugar, we categorize them as synthetic due to their manufacturing process.

• Artificial polyols include isomalt and maltitol because even though they're made from natural materials, they're not found in nature.

Most polyols are derived from glucose or glucose syrups (from starch), while others come from sucrose (sugarcane or sugarbeet), lactose (milk), or xylose (wood).  

How do polyols behave in our bodies?

Polyols provide fewer calories than sugar because they resist digestion—some to a greater extent than others. Here's how our bodies process them:

​

• Absorption in the small intestine:
  They're partially absorbed in the small intestine, but to different degrees. For example, erythritol has a fast and partial aborption (60 to 90 % of ingested erythritol), while xylitol is absorbed slowly and in smaller amounts (only 1/4 of the ingested amount).
   

• Metabolism:
  Some of these sweeteners are slowly digested, while others undergo only partial metabolism. For instance, erythritol isn't metabolized — though a small portion passes intact into the large intestine. Since erythritol isn't converted into glucose, it have no effect on blood sugar levels.
  
  On the other hand, xylitol is slowly absorbed and converted into glucose, so it does not cause a sudden increase in blood sugar.

• Fermentation in the large intestine:
  The portion that is not digested by gut enzymes reaches the large intestine, where they may be fermented by the microbiota (healthy bacteria in the gut) or excreted in feces.
  
  This fermentation has both drawbacks and benefits. It can cause digestive issues such as bloating, flatulence, and diarrhea. However, they may act as prebiotics, by stimulating the growth and activity of gut microbes. 
  
  If too much polyol reaches the large intestine, it may act osmotically by drawing water from the body, resulting in loose stools.
   

• How come erythritol is not digested and still have calories?
  Even though we cannot metabolize erythritol, bacteria in the lower digestive tract can. The low caloric value attributed to eryhtritol is because microbes metabolize them, and we obtain their energy indirectly. This is why erythritol is the only polyol that can be labeled as "zero-calories".

​

What are polyols' calories?

Erythritol is the polyol with the lowest caloric value — 0.2 to 0.4 calories per gram. Since its caloric value per gram is very low, the Food and Drug Administration (FDA) regulations for nutrition labels rounded it to zero. To compare with other polyols: Isomalt—2.0, xylitol—2.4, maltitol—2.1, sorbitol—2.6, mannitol—1.6. ​​

​

Are all polyols sugar-free?

Yes. While all polyols are sugar-free sweeteners, they're not calorie-free and can have different effects on blood sugar levels. For example, maltitol has a higher glycemic index than other polyols, meaning it can cause a more significant increase in blood glucose. On the other hand, erythritol is an exception — it's calorie-free and has zero glycemic impact.

How do I track sugar alcohols? 

Read the Nutrition Facts label if you want to monitor erythritol or any other polyol in your diet: 
 

1. Start by checking the list of ingredients
   If erythritol is present, confirm if it contains other sugar alcohols, such as xylitol, mannitol, sorbitol, isomalt, or maltitol. Currently, erythritol is way more popular than all the other sugar alcohols, so a much more common ingredient.
    

2. Move on to the nutrition facts label
   Under “Total Carbohydrates”, look for "Sugar Alcohols." If no other sugar alcohol is present, the amount listed is the total amount of erythritol PER SERVING. Note that by law, food manufacturers are not required to list the amount of sugar alcohols. However, they must include it if they make claims like sugar-free and no-added-sugar, which are common in zero-calorie, low-carb, and keto foods. 

What is considered an excessive amount of sugar alcohol?​

Among polyols, sorbitol and mannitol are the most likely to lead to adverse digestive issues, while erythritol tends to cause the least. By law, products with sorbitol and mannitol must include a warning on their label stating "excess consumption may have a laxative effect".  

For sorbitol, the FDA suggests that over 50 grams of sorbitol per day is considered excessive, in terms of potential digestive side effects. For mannitol, the limit is 20 grams.

Erythritol is generally better tolerated, with a 150-lb person able to consume up to 68 grams (or 5.5 tablespoons) without gastric discomfort. However, the same and lower doses consumed by simply dissolving it in water or in dry form after fasting might result in laxation and other digestive issues.

Individual tolerance varies – some people are more sensitive to these sweeteners than others.
