I want to know whether the Stevia is good to use?
The new sweeteners on the market that contain stevia actually contain what is called stevia extract. This is not the same as the stevia that one can purchase in a health food store. Nonetheless, the new stevia-based sweeteners, which currently include Truvia, PureVia and Stevia in the Raw, are all non-nutritive sweeteners. This means that they don’t contain calories or carbohydrate, so you can use them in your eating plan, just as you would use aspartame, saccharin or sucralose. These sweeteners, by themselves, do not impact blood glucose levels. You can bake with some of them, too, but check the package or the product’s website for instructions. There’s no real benefit to using a stevia-based sweetener over other types of non-nutritive sweeteners. The decision is usually based on individual preference, as one may taste different to you than another.
