Stevia Leaf Powder

Introduction

Stevia Leaf Powder is made by carefully cleaning, drying, and finely grinding the leaves of the Stevia rebaudiana plant. This plant is native to the regions of Paraguay and Brazil in South America, where it has been used for centuries as a natural source of sweetness.

The leaves contain naturally occurring compounds known as Steviol Glycosides, which are responsible for their intense sweetness. Stevia is approximately 200–300 times sweeter than regular sugar (sucrose) while providing little to no calories. Because of this unique property, it has become one of the most popular natural zero-calorie sweeteners worldwide.

Stevia is widely preferred by people managing diabetes, controlling their weight, or seeking healthier alternatives to refined sugar.
