Those products are designed to remove acid form the body and alkalize. The Stevia alkalizes. Greens, especially spirulina have natural sugars so it tastes a little sweet. I would use those products until they are gone before considering ordering anything else.
Sarcasm on. Last night I was on my alkalizing diet Cosco chocolate chips and pepperoni pizza. Sarcasm off. Because I was on 5 drops of Miracle-Mineral-Supplement with a teaspoon of green powder I was still very alkalized.
