Selenium is an essential trace mineral popularly termed the "miracle mineral" - and with good reason - for it boasts many health protection benefits. Selenium is believed to offer powerful antioxidant properties that can form a protective shield around the body's cells from the stress caused by those nasties known as free radicals. Each of our high-strength Selenium tablets helps with the absorption of iodine - something that is vital for a hale and hearty thyroid gland. It makes sense therefore to take the two together (look for Kelp in our shop). The thyroid gland is responsible for releasing into the body hormones that influence its metabolic rate and mineral levels.
