What monk fruit sweetener is
The FDA lists monk fruit extract, also called luo han guo or Siraitia grosvenorii Swingle fruit extract (SGFE), among plant and fruit-based sweeteners with GRAS notices it has not questioned under the intended conditions of use. It says SGFE, depending on its mogroside content, is reported to be 100 to 250 times sweeter than sugar, and that an acceptable daily intake has not been specified for monk fruit.
Based on the available scientific evidence, the FDA says sweeteners it has authorized are safe for the general population under certain conditions of use.
Pure extract vs blends
| Product type | What's in it | What to know |
|---|---|---|
| Monk fruit and erythritol blend | Monk fruit extract plus erythritol, a sugar alcohol | Widely sold granulated blends; check how much of the bag is erythritol |
| Monk fruit and allulose blend | Monk fruit extract plus allulose | Lakanto says its Classic with Allulose has zero calories and dissolves like sugar |
| Liquid drops | Monk fruit extract in liquid form | Lakanto says its liquid drops have no erythritol; made for drinks |
Blend details are from Lakanto's product pages. Granulated products are blended so they measure more like sugar, since pure extract is far sweeter than sugar.
The erythritol question
Many monk fruit blends use erythritol as the bulk ingredient. A 2023 study in Nature Medicine found that in patients undergoing cardiac risk assessment, higher blood erythritol levels were associated with a higher 3 year risk of major adverse cardiovascular events, in a discovery group of 1,157 people and validation groups of 2,149 and 833. In lab and animal work, erythritol enhanced platelet reactivity and clot formation, and in 8 healthy volunteers, eating erythritol raised blood levels for more than 2 days.
This was an association study in people already at cardiac risk, not proof that erythritol causes heart attacks, and the authors called for long-term safety studies. If you have heart disease or clotting risk, or simply prefer to avoid it, choose erythritol-free drops or an allulose blend and talk with your doctor.
How to choose
- Read the ingredient list. Check whether the bulk is erythritol, allulose or another sweetener, and whether the label says pure extract.
- Match the form to the job. Liquid drops suit coffee and tea; granulated 1:1 blends suit baking and recipes.
- Check the ratio. Granulated blends and drops are not equally sweet, so follow each package's sugar-swap directions.
- Start small. Try a small amount first to check taste and how your stomach handles the blend.

Monk fruit vs other sweeteners
The FDA lists six sweeteners approved as food additives: aspartame, acesulfame potassium, sucralose, neotame, advantame and saccharin. It separately lists three plant and fruit-based sweeteners with GRAS notices it has not questioned: steviol glycosides, monk fruit extract and thaumatin. Steviol glycosides are reported to be 200 to 400 times sweeter than table sugar.
All of these are high-intensity sweeteners that add sweetness with little or no sugar. Swapping sugar for a sweetener is one choice among many; overall diet still matters most.
Using monk fruit in recipes
- Follow the maker's conversion ratio rather than swapping cup for cup unless the bag says 1:1.
- Expect differences in browning and texture in baked goods, since sugar adds bulk and moisture.
- Lakanto says its allulose blend dissolves like sugar, keeps baked goods moist and has no cooling effect.
- For drinks, start with a few drops and adjust.
