When glutathione is depleted - as seen in autoimmune thyroid disease - HO accumulates, causing oxidative damage to thyroid follicular cells
Most of the studies done so far have been in rodents -- results that don't always hold up when larger studies are done in people
This can result from chronic oxidative stress, heavy metal toxicity (especially iron overload), persistent infections, nutrient insufficiencies (sulfur amino acids, glycine, glutamate, selenium, B-vitamins), liver dysfunction, metabolic stress, and genetic polymorphisms in key enzymes like glutamate-cysteine ligase (GCL) or glutathione S-transferases (GSTs)
Red Flags Requiring Immediate Attention Severe allergic reactions are extremely rare but possible
