This sweetner is safe for diabetics... See the Mayo Clinic's article on this one..

shortened summary for common drinks:

C2 --- 12 apspartame, 12 ace-k, 2 sucralose
Coke Zero 58 asp, 31 ace-k
Diet Coke 125 asp
Diet Cherry 50 asp, 34 ace-k
Sprite Zero 50 asp, 34 ace-k
Diet Mello Yello 38 asp, 86 ace-k

So assuming equal toxicity among sweeteners C2 is healthier than the others as the total dosages are lower.

I thought Ace-K was just a modifier, not a sweetener...?
