Monk fruit, also known as lo han guo, is a small round fruit grown in Southeast Asia. It has been safely used for centuries in Eastern medicine as a cold and digestive aid, and now it is also being used to sweeten foods and beverages. Monk fruit sweetener is created by removing the seeds and skin of the fruit, crushing the fruit, and collecting the juice. The fruit extract, or juice, is around 150-200 times sweeter than sugar and contains zero calories per serving – meaning a very small amount provides a lot of sweetness.
