Immune System Support

Selenium is crucial for the proper function of white blood cells and T-cell activation, enhancing immune response against infections. Research suggests that selenium deficiency is linked to impaired immune function and increased susceptibility to illness.
https://pmc.ncbi.nlm.nih.gov/articles/PMC3277928/

Selenium plays a crucial role in modulating both innate and adaptive immune responses. It influences the proliferation and activation of immune cells, including natural killer cells and T lymphocytes. Studies have shown that selenium deficiency can impair immune function, leading to increased susceptibility to infections, while adequate selenium intake supports robust immune defense.

PMhttps://pmc.ncbi.nlm.nih.gov/articles/PMC3277928

Essential for Thyroid Health

The thyroid contains more selenium per gram than any other organ in the body. This trace mineral is necessary for the production of thyroid hormones (T3 & T4) and helps prevent iodine deficiency-related thyroid disorders.
https://pmc.ncbi.nlm.nih.gov/articles/PMC5307254/

Selenium is vital for the synthesis and metabolism of thyroid hormones, as it forms part of the enzymes that convert thyroxine (T4) into the active triiodothyronine (T3). Adequate selenium levels help maintain optimal thyroid function and protect the gland from oxidative damage.
https://pmc.ncbi.nlm.nih.gov/articles/PMC10080082

Supports Healthy Hair, Skin & Nails

Selenium is involved in keratin production, helping to maintain strong nails, vibrant skin, and healthy hair growth. It also aids in reducing inflammation and preventing premature aging caused by oxidative stress.
https://pmc.ncbi.nlm.nih.gov/articles/PMC9570904/
https://pmc.ncbi.nlm.nih.gov/articles/PMC9570904/
Selenium contributes to the maintenance of healthy hair and nails by supporting the synthesis of selenoproteins involved in cellular protection and function. Its antioxidant properties help combat oxidative stress, which can affect skin health and accelerate aging. Ensuring sufficient selenium intake may promote strong hair and nails and support overall skin vitality
