GLUTATHIONE

With 18 known gene hits, glutathione is known as "the mother" of all antioxidants and is key to immune system function. Higher glutathione levels are associated with enhanced physical health, fewer illnesses, and improved quality of life. 

Glutathione is produced in the liver and synthesized from cysteine, glutamic acid, and glycine. Levels of glutathione can be measured in urine by determining your 8-oHdG biomarker. 

You can also order DNA tests to determine your genotype in the key genes that utilize glutathione as a nutrient cofactor.
