A system and method for production of fatty acid ethanolamides (FAEs) are provided. The system and method for production of fatty acid ethanolamides includes microbes engineered to express the necessary enzymes to complete a FAE biosynthetic pathway, resulting in the conversion of glucose to one or more desired FAEs. The microbes may be engineered to express at least two of thioesterase, fatty acyl CoA synthase, NAPE-synthase, and NAPE phospholipase-D. The FAE-producing microbes can be administered to a subject in need thereof as part of a probiotic regimen.
