Stevia is a naturally sweet plant that has almost no impact on blood sugar. It is usually commercialized as stevia EXTRACT - either as a white powder or liquid drops or in combination with erythritol. Those products are highly processed and not natural. This Aurospirul stevia is a green powder made from the REAL & WHOLE organic stevia plant. You only need a tiny bit to sweeten your drinks or foods. Taste-wise it comes with the typical stevia bitterness that some people love and some people hate.
