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.
