  • This is looks like a fairly labor-intensive search. Could you help us by narrowing it down to particular amino acids or vitamins, at least for a starting point?

The patent you're referring to might have been anticipated by https://www.google.com/patents/EP1877094A1 "Edible film for transmucosal delivery of nutritional supplements" :

"ABSTRACT In one embodiment of the present invention a composition is provided comprising a film layer wherein the film layer rapidly dissolves in an oral cavity and a coating comprising a powder matrix, wherein the coating is applied to at least one side of the film layer and wherein the powder matrix comprises a nutritional supplement, an adhesive, a bulking agent, a flow agent, and a sweetener."
