NutraMedix Stevia is an extract from the leaves of Stevia rebaudiana which has around 300 times the sweetness of sugar. NutraMedix stevia does not leave the bitter after taste that many other forms have. Stevia does not cause the release of insulin and so can be used by diabetics or people wanted to lose weight, or just reduce their sugar intake. It may be used in tea, coffee and recipes in place of sugar. Four drops of Stevia is equivalent to one teaspoon of sugar.
