What Is Monk Fruit Sweetener?

Monk fruit sweetener is made from monk fruit (luo han guo), a small melon-like fruit native to southern China. The sweetness doesn't come from sugar at all — it comes from compounds called mogrosides, extracted from the fruit's pulp and concentrated into what's sold as monk fruit extract. Mogrosides are roughly 100–250 times sweeter than table sugar by weight, which is why finished products use so little of the actual extract, often bulked out with another ingredient to make it measurable and scoopable.

That last detail is the one most buying guides skip, and it's the reason two "monk fruit sweetener" bags on the same shelf can behave completely differently in your coffee or your cookie dough.

Luo Han Guo Monk Fruit: The Traditional Name

You'll see the fruit itself listed as lo han monk fruit or luo han guo, especially on ingredient panels and in traditional Chinese medicine contexts, where it's been used for centuries as a soothing ingredient in teas. Same fruit, same mogrosides — "monk fruit" is simply the Western marketing name that stuck.
