I get Kal brand stevia, it has one ingredient, Stevia Extract. It also has no funny aftertaste that some other brands have. My local grocery story doesn't carry it so I have to get it online.

I get it here:

There are over 1800 scoops per container, so it isn't as expensive as it seems. I find I use 3 scoops in a cup of coffee where before Low Carb I used to use 2 rounded spoons of sugar.

Moderators, if this is against policy, let me know and I'll not post a link anymore. BTW, I have no affiliation with that company other than being a customer.
