Dreamfields sent my BG high hours later & it wasn't inulin that was responsible for the rise, but the wheat. Fiber in Dreamfields simply slowed down the effect. Personally, I think Dreamfields is a scam.
The amount of inulin in stevia must be quite a small amount.
Hard to say if it was the inulin that caused a 10 pt. increase because there are innumerable factors at play.
