Chem-Defense is a nutrient blend formulated for persons with chemical sensitivities. Recent scientific research indicates that molybdenum, a trace mineral that activates the enzymes aldehyde oxidase and sulfite oxidase, may provide necessary nutritional support for chemically sensitive individuals. Glutathione (GSH) is a key element of the liver's detoxifying process, and is also the precursor for glutathione peroxidase, a major free radical-scavenging enzyme. Ribolflavin is the precursor for FAD, a coenzyme which recycles used GSH. The benefit of the sublingual form is that it is absorbed directly into the bloodstream, via the blood vessels under the tongue and in the cheeks, allowing for quick entry into the system.
