Glutathione has been noted to be the most important antioxidant produced in the human body and is present in every cell of the body. With a myriad of functions, it may act to help protect cells from toxic exposures such as pesticides, fungicides and toxins in the air we breathe. It also supports the chelation of heavy metals which acts as a protectant against metals such as lead, arsenic, cadmium and mercury. Additionally, VARS Liposomal Glutathione Spray from Setria® contains reduced Glutathione which is the most bio-available form of Glutathione. It is a tripeptide consisting of three amino acids: Glutamate, Cysteine, and Glycine. Glutathione may help fight free radicals, and supports healthy liver function, nervous system and immune system.
