Can you take xenical and glutathione at the same time?

Yes: Yes, xenical is really just a "fat binder." it binds cholesterol and triglyceride in the gut and blocks absorption of these molecules. Glutathione is an amino-acid that acts as an anti-oxidant in the body. There is a possibility that the xenical may decrease the absorption of the glutathione if they are taken together (ingestion within two hours of each other).

Drug Interaction: According to epocrates, a medical application, there is no interaction between glutathione and xenical.
