Monk Fruit Sweetener: Mostly Erythritol?

Monk fruit extract is intensely sweet, so packs use very little of it. Most granulated monk fruit sweeteners are about 99% erythritol, which matters for FODMAPs.

Monk fruit, or luo han guo, is a small round melon from southern China. Its sweet compounds, called mogrosides, are so strong that a sweetener needs only a trace of the extract.

So the bag labelled "monk fruit" is usually mostly erythritol, and sometimes allulose. That matters if you avoid polyols or follow a low FODMAP diet. Pure extract drops are the exception.

What to look for when buying monk fruit

How much monk fruit is in it? Consumer NZ could not find a spoon-for-spoon monk fruit sweetener with more than 1% monk fruit. Erythritol was the main ingredient in each case. In Open Food Facts listings we checked:

If you avoid erythritol, choose drops or an allulose blend.

Side effects and who should be careful

Monk fruit extract has been through several US GRAS notices, and the FDA has not questioned them. No acceptable daily intake has been set for it. Because most products are mainly erythritol, also read the erythritol page.

Questions about monk fruit

Does monk fruit raise blood sugar?

The extract is used in tiny amounts and is not counted as sugar. Check blends: one liquid product we found lists agave nectar first.

Can monk fruit sweetener cause diarrhoea?

The monk fruit is unlikely to. Most granulated blends are mostly erythritol, and large amounts of polyols can upset the gut.

Is monk fruit better than stevia?

They are used the same way, and both are usually mixed with erythritol. Taste is the main difference, so try both.
