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