Input (English): I am so happy I discovered this product. I had tried several other brands in extract and powder form and NuNaturals is by far the best. Virtually NO aftertaste, quick dissolving and convenient. It is also very economical at 1.5 cents a serving. I use a 1/4 teaspoon measuring spoon and it sweetens my coffee or tea perfectly. Do yourself a flavor and get this stevia powder - you'll be happy you did!
