Will, Will, Will
Any sweetener, natural or not, that comes in a powdered form has dextrose or maltodextrin to bulk it up and even though a packet says "less than 1 gr carb", it will still affect your blood sugar if you're using more than one packet. I have tried the powdered forms of stevia, saccharine, sucralose, aspartame, stevia with erythritol, etc. and they all affect my blood sugar because I'd use about
four packets in my mug of morning coffee. And, yes, it is a large mug.
Now, there are little bottles of liquid stevia, monk fruit, agave and sucralose available which should have less impact on blood sugar because there is no dextrose in them.
The bottom line is: test, test, test. Test before you eat or drink anything with those sweeteners and test an hour and about
two hours afterward to see what the impact is on you.
Calories are not the same as carbohydrates. None of these sweeteners have calories but when you're affected by carbs, you do need to be careful with the powdered sweeteners.
Also, many of the vitamins available today are in the form of chewable 'gummies' or tablets and these will also raise your blood sugar if you're taking a bunch of different ones because in order for them to be palatable, they have artificial sweeteners. A word to the wise.
