PneumoVen provides a superior combination of natural vegetarian enzymes (such as bromelain, derived from the pineapple plant), NAC (n-acetyl-l-cysteine), and a broad spectrum of select botanical support agents for effective lung support. Bromelain offers proteolytic enzymes that promote the breakdown of proteins. NAC (N-acetyl-L cysteine) is a source of the essential amino acid, L-cysteine, and is a precursor to the important antioxidant, glutathione. NAC supports detoxification in the liver. Additional biocompatible botanical agents are included for optimal nutritional support.
