Additive 3.0 was the name given to the Leviathan's newest food additive.
It was placed in dairy creamers, and was designed to kill off humans with undesirable traits - such as low body mass and hemophilia.
Dick Roman gave a demonstration of the additive in front of all the other high ranking Leviathan at a conference. He injected a human girl Polly with a concentrated dosage of the Additive. Polly convulsed and died within a matter of seconds. Dick intended to ship the Additive to Los Angeles, but his plans were foiled when the Winchesters attacked SucroCorp.
