Monk fruit (luo han guo, *Siraitia grosvenorii*) is a small Asian melon whose extract is 150–200 times sweeter than sugar. The sweetness comes from mogrosides — antioxidant compounds the body doesn't metabolize, so monk fruit delivers sweetness with zero calories and zero glycemic impact. The FDA classifies monk fruit extract as GRAS (Generally Recognized As Safe). It's been used in Chinese traditional medicine for ~800 years.
For kids, the AAP 2019 policy statement groups monk fruit with stevia as a non-nutritive sweetener with a "longer history of safe traditional use" than synthetic sweeteners. There's no separately published Acceptable Daily Intake from the FDA — the GRAS classification means the agency has no specific upper limit, which is rare for sweeteners. The European Food Safety Authority has not issued a formal monk fruit ruling but the ingredient is permitted in EU food products.
In our catalog, monk fruit appears in most low-sugar kid cereals (often blended with stevia), sugar-free baking mixes, and a handful of beverage SKUs. Lakanto is the largest US monk fruit brand; their kid-targeted granola is one of the few standalone monk-fruit-sweetened bars on shelf. The blend approach is common because monk fruit has a slight melon aftertaste; pairing with stevia or allulose neutralizes it.
How to spot it on a label: "Monk fruit," "Monk fruit extract," "Luo han guo," "Mogrosides," or branded "Lakanto." Sometimes blended with erythritol or allulose as a 1:1 sugar substitute — those products carry an "erythritol" or "allulose" line you should also notice (separate ingredient pages cover both).
