Each capsule provides 200 mcg of selenium, delivering 364% of the Nutrient Reference Value (NRV), making it suitable for long-term daily use when taken within recommended guidelines.
Why Selenium Is Important
Selenium contributes to:
-
Normal thyroid function
-
Normal function of the immune system
-
Protection of cells from oxidative stress
-
Maintenance of normal hair
-
Maintenance of normal nails
-
Normal spermatogenesis
Because selenium intake depends heavily on soil quality and diet, supplementation is often considered in individuals with limited dietary sources.
Thyroid Support
Selenium plays a key role in the metabolism of thyroid hormones. It contributes to the normal conversion of thyroxine (T4) into the active hormone triiodothyronine (T3), which is essential for regulating metabolism and energy balance.
Adequate selenium intake supports the normal functioning of the thyroid gland, which influences energy levels, metabolic rate and overall hormonal balance.
Antioxidant Protection
Selenium is a component of important antioxidant enzymes such as glutathione peroxidase. These enzymes help protect cells from oxidative stress caused by free radicals.
Oxidative stress can increase during:
-
Periods of physical stress
-
Environmental pollution exposure
-
Smoking
-
Intense physical activity
Supporting antioxidant defence is essential for long-term cellular health.
Immune System Function
Selenium contributes to the normal functioning of the immune system. It supports immune cell activity and plays a role in maintaining the body’s natural defence mechanisms.
Adequate intake is especially relevant during seasonal changes or periods of increased physical demand.
Highly Bioavailable Form – L-Selenomethionine
L-selenometionine is an organic form of selenium bound to the amino acid methionine. This form is efficiently absorbed and incorporated into body proteins, supporting optimal selenium status.
Compared to some inorganic forms, L-selenometionine is generally considered superior for bioavailability.
Who Is It Suitable For?
Selenium 200 mcg is suitable for:
-
Adults seeking thyroid support
-
Individuals interested in antioxidant protection
-
Men seeking reproductive health support
-
