Thyroid hormones increase ROS release in the mitochondrial respiratory chain ( Figure 1 ) ( 5.1 Thyroid dysfunctions and OxS 5.1.1 Hypothyroidism Even in its subclinical form, hypothyroidism reduces antioxidant system activity, which promotes OxS, causing oxidative damage and altered lipid metabolism in thyroid cells ( 5.1.2 Hyperthyroidism ROS generation is increased by hyperthyroidism ( 5.2 Thyroid disorders and OxS 5.2.1 Nodular goitre OxS promotes thyroid cell proliferation ( Additionally, rare loss-of-function germline mutations of Kelch-like ECH-associated protein 1 (KEAP1) could be detected in nodular goitre leading to Nrf2 pathway activation that favours transcription of cytoprotective and antioxidant enzymes ( 5.2.2 Autoimmune thyroid diseases 5.2.2.1 Hashimoto thyroiditis By interacting with TPO and thyroglobulin (TG) and promoting immunogenicity by altering their morphology and function, NADPH-oxidases (NOXs) involvement in the production of hydrogen peroxide (H 2 O 2 ) regarding thyroid hormone synthesis may be related to the pathophysiology of AITD ( Because it increases ROS production and lowers antioxidant levels, excessive iodine consumption is considered an additional risk factor for developing AITD

Protecting Cells from Damage Glutathione helps shield cells from oxidative damage by neutralizing free radicals and supporting cellular repair, particularly in organs like the liver
These features highlight their potential as carefully selected live biotherapeutics, rather than just randomly chosen fermenters
