Hi there - agave is second to stevia in terms of glycemic impact (second lowest) has a honey like texture and similar taste. There is a glycemic index list available that tells you in order which is the best and worst. I have yet to find a complete list or carbohydrate values for them though,,, I'll post if I do. Not everyone likes stevia it's an acquired taste but mixed into a fruit smoothie its not that bad. It can be very sweet so only small amounts are needed.
