Can you have too much stevia?

We like our tea on the sweet side here, and drink it all day in the cold weather. I get Trader Joe's 100% organic stevia extract and have 2 of those tiny little scoops in each cup of tea...and probably 5-6 cups of tea a day. Any reason to lighten up?

Also, what is an inexpensive source for stevia?

Do I reduce the bitter effect of my jiaogulan tea by putting stevia in it?

Thank you. Tweet
