The fine print of a commercial talking about the Edward macronutrient
The Edward macronutrient was a type of macronutrient that allegedly contained the DNA of Edward Larkin.
According to a commercial, Tribbles cereal contained the Edward macronutrient, although at the time it had not yet been approved by the Federation Food and Drug Administration. (ST: "The Trouble with Edward")
This cereal commercial was presented in a post-credit scene of the aforementioned Star Trek: Short Treks episode. The context of the commercial from the in-universe perspective is impossible to determine, and may not have been meant to be taken literally.
