I don't know. It is a simple sugar and I think the dosage without infection is half a teaspoon a day and 1 teaspoon a day if there is infection. There is a question section for the product on Amazon where you can ask. I found the reviews very helpful on how to use, too. Even though I don't get infections anymore, I take 1 teaspoon daily in 4 oz water at noon just to be on the safe side. I use the product that comes in a white bag with orange person on it. It was life changing for me.
