I went to replace a supply of Stevia this morning and read most of the boxes before purchasing. Some call themselves a “stevia blend” some just say stevia. Most had erythritol as a second ingredient. I didn’t see any that were pure stevia. I ended up selecting one with dextrose as the second ingredient, mostly because I remembered this thread and didn’t want to be running to the bathroom 45 minutes after finishing my iced coffee. Isn’t dextrose sugar? How do they stay at 0 calories per serving? Why can’t I find a box of pure stevia?
