You cannot assume anything from this study when the Sweet Leaf brand was used at here are the ingredients...inulin, stevia leaf extract and silica.

My wife gets a brand that is JUST Stevia, Stevia Select.

Unfortunately, it does come from Red China, as does almost all U.S. Stevia. I have been told that the Japanese buy up the entire Paraguay crop at top dollar.
