Palmitoylethanolamide (or shorter PEA) is body own endocannabinoid, that can also be found in plant, nuts, rice and many more. It is a molecule synthesised by the human body. In body high concentrations of PEA is found especially in areas where pain caused by inflammation is present. PEA is poorly water soluble, which indicates an absorption by micellar passive diffusion in the intestine. This effect is strongly increase by liposomal encapsulation of the substance.
