Low FODMAP sweeteners are an increasingly popular way for many people with irritable bowel syndrome (IBS) and/or small intestinal bacterial overgrowth (SIBO) to be able to have their cake and eat it too – quite literally. 😉
While the low FODMAP diet isn’t a be-all-end-all solution (since gut health is complex, and one size never fits all), it can still often serve as a great nutritional “backbone” for many who are in the early stages of navigating IBS and/or SIBO.
Whether you’ve been prescribed a low FODMAP diet and/or you’re navigating SIBO, and/or you suspect you have a fructose intolerance, I hope this guide on low FODMAP sweeteners helps to give you some clarity on your journey to IBS relief!

What are sweeteners?
In the context of this article, “sweeteners” is referring to any variation of a sugar or sugar substitute that could be added to foods/beverages, to make them taste sweeter. (Think honey, maple syrup, brown sugar, corn syrup, Splenda, stevia, monk fruit, aspartame, xylitol, etc.)
Nutritive vs non-nutritive sweeteners
- Nutritive: provides calories by getting metabolized as sugar; turns into blood glucose in the body.
- Non-nutritive: does not get broken down and absorbed as sugar; does not provide any significant calories.
What does “low FODMAP” mean?
FODMAP is an acronym which stands for “fermentable oligosaccharides, disaccharides, monosaccharides, and polyols.” (Feel free to try saying that 10x fast, if you’re feeling ambitious!)
About 3 out of every 4 IBS sufferers will likely respond well to a low FODMAP diet intervention from a symptom management standpoint, according to research at this time. (1)
In my functional nutrition practice, I’ve noticed that leaning on low FODMAP sweeteners (versus their high FODMAP counterparts) is helpful and relevant for people who have trouble digesting fructose and/or polyols, which are FODMAPs found in many types of sweeteners.
If a sweetener meets criteria for “low FODMAP”, that means it contains relatively low amounts of fructose and polyols.
- Fructose and polyols are FODMAP constituents which are notorious for triggering IBS symptoms.
List of low FODMAP sweeteners
Below is a list of sweeteners that meet criteria for “low FODMAP” – but that doesn’t necessarily mean I endorse them all from a health standpoint.
- Read more about my favorite sweeteners for IBS, here.
Some of these nutritive sweeteners may be used when cooking/baking, while others might be found exclusively on ingredient labels of certain procesed foods/drinks. You may also encounter some of these in coffee shops. Refer to this list as needed.
Note: Some sweeteners may meet criteria for low FODMAP only in small quantities, so I’ve made sure to specify the max threshold for those sweeteners to be low in fructose/polyols.
Low FODMAP nutritive sweeteners
- Table sugar (beet sugar, cane sugar, “white sugar,” Domino sugar, “sucrose”)
- Brown sugar
- Coconut sugar (less than 1 tablespoon)
- Coconut palm sugar (less than 1 tablespoon)
- Maple sugar* (less than 2 tablespoons)
- Sugar In The Raw®*

- Palm sugar*
- Tapioca syrup
- Confectioners sugar
- Dextrose (derived from corn and/or wheat)
- Maple sugar powder*
Low FODMAP non-nutritive sweeteners
Non-nutritive sweeteners are exponentially sweeter than regular sugar, so they only need to be consumed in very small quantities – even when they’re diluted with a powder (like dextrose or erythritol), or a liquid medium (like alcohol or glycerin).
These types of sweeteners are appealing for people who are trying to reduce their intake of calories/sugar, for one reason or another. However, they aren’t necessarily healthy for the gut microbiome (ecosystem of microbes in the gut) or for health in general.

So, if a sweetener is low in FODMAPs, does that mean it’s healthy? Not necessarily! But either way, it is less likely to trigger your symptoms compared to many high FODMAP alternatives.
However, in many cases, people with IBS who don’t have a fructose intolerance are actually able to tolerate certain types of high FODMAP sweeteners, especially if they’re natural and minimally processed.
