Elevated glutathione levels may reflect an accumulation resulting from impaired recycling, often due to deficiencies in NADPH, selenium, or riboflavin (vitamin B2). This indicates a disruption in the redox balance rather than Riboflavin for women's health and emerging microbiome strategies npj Biofilms and Microbiomes Vitamin B2 A dual emissive silver riboflavin complex and nitrogen doped carbon dot nanoprobe for ratiometric detection of glutathione ScienceDirect Elemental Selenium and Vitamin B2 (riboflavin) are essential for glutathione use and recycling. Selenium is really low in Australian soils, and people are commonly deficient. Signs of low B2 are blood
