Selenium is present in the structure of enzymes such as deiodinases, glutathione peroxidase, thioredoxin reductase, and thyroperoxidase. This element plays a role in cell defense against oxidative stress and regulating thyroid hormone function.

What are the symptoms of selenium deficiency?
Selenium deficiency can cause endemic cardiomyopathy, neuromuscular disorders, and increased serum creatinine levels in children, which is known as Keshan disease. Selenium deficiency can weaken the immune system by reducing the production of selenoproteins. In cases of selenium toxicity, symptoms may include hair and nail loss, garlic breath, irritability, and mild nerve damage. Selenium levels in the blood can be measured using CFAAS.
