Selenium and Heart Health

Adequate selenium intake can support cardiovascular health, as this essential trace mineral plays a role in reducing inflammation and oxidative stress. Selenium contributes to the maintenance of healthy blood vessels and supports normal circulation. Its antioxidant function helps protect cardiac tissue from damage caused by free radicals, which may in turn help reduce the risk of heart disease.¹ ²

What is the Difference Between Selenium and L-Selenomethionine?

Selenium can be found in various forms, with L-selenomethionine being one of the more bioavailable options. This compound consists of selenium bound to the amino acid methionine, which allows for more efficient absorption and utilisation by the body. Although all forms contribute to selenium intake, L-selenomethionine is often preferred for its ability to support optimal selenium status more effectively.³ ⁴

Can Selenium Support Thyroid Health?

Thyroid health relies on adequate selenium levels, as this mineral is essential for the conversion of thyroxine (T4) into its active form, triiodothyronine (T3). Selenium also contributes antioxidant protection to the thyroid gland, helping to minimise oxidative stress. By supporting both hormone conversion and cellular defence, selenium plays a critical role in maintaining optimal thyroid function and metabolic regulation.⁵ ⁶

Selenium for Hair, Skin, and Nails

As an essential antioxidant mineral, selenium plays a key role in maintaining healthy hair, skin, and nails. It combats damaging free radicals to help prevent premature skin ageing and supports nail strength by helping to minimise brittleness and breakage.⁷ ⁸

Antioxidant Properties of Selenium

As a potent antioxidant, selenium functions as a critical cofactor for enzymes such as glutathione peroxidase. These enzymes neutralise free radicals in the body, protecting cells from oxidative damage that can lead to ageing, inflammation, and various chronic conditions.⁹
