Selenium is an essential trace mineral important for various bodily functions such as detoxification, immune response, inflammation control, and thyroid hormone metabolism. Insufficient selenium levels are linked to several health issues including cardiomyopathy, thyroid disorders, and increased risk of some cancers and cardiovascular diseases.
Selenium also plays a critical role in converting the thyroid hormone T4 into its more active form, T3, and supports antioxidant activity in the body.
Conversely, excessive selenium intake can lead to toxicity, which can contribute to diabetes, hypertension, and dermatological issues like alopecia and dermatitis. Monitoring selenium levels is important, especially in the context of diseases or conditions such as inflammation, chronic illnesses, and aging.
Red blood cell selenium measurement may offer a more accurate reflection of long-term selenium status compared to serum levels, which fluctuate with current intake.
