The Zetpil Melatonin Plus suppository as developed after pharmacological research offered clear evidence that melatonin is best absorbed via the rectum. Accordingly, the scientist and development team at Zetpil have developed a formulation that combines melatonin, the precursors for reduced glutathione formation, key antioxidants in a proprietary base that was specially developed to further enhance absorption of all the bioactive ingredients. Note melatonin has been shown in repeated studies not only to maintain the levels of the cellular antioxidant glutathione but to actually increase glutathione levels. This is especially important since individuals using classical antioxidants such as Vitamin C, Vitamin E actually deplete the cellular antioxidant rGSH. Below is the MelatoninPlus Suppository list of ingredients.

Each MelatoninPlus suppository contains the following: Melatonin 80mg; A Proprietary Blend contains a therapeutic dosage of N-Acetyl-Cysteine, L-Glutamine, Acety=L Glutamine, L Gluamine, L-Alanyl-l-Glutamine, N-Acetyl-Carnitine, L-Taurine; Calcium 180mg; Vitamin C 50mg and Selenomethionine 40mg.
