Selenium and the Immune System

Everyone needs minerals and they are needed in varying amounts depending on the mineral. This is because each mineral has a different set of functions in the body. Mineral requirements also vary according to age, gender and physiological state, such as menopause. Although a varied and balanced diet should provide us with the minerals we need, some individuals may need the additional help of supplementation.Today’s focus is on selenium, a trace mineral. The dietary need of trace minerals is less than 100 milligrams per day – hence the adjective. Selenium can be found in a variety of foods including Brazil nuts, whole grains, fish, meat and eggs. Despite this, in the UK and Europe selenium, intake is suboptimal mostly due to inadequate selenium levels in soil.  The UK reference nutrient intake (RNI) for selenium is 60 ug for adult women and 75 ug for adult men. In addition, EFSA notes the tolerable upper intake limit (UL) for selenium is 300 ug per day.Selenium has a variety of functions within the body including protecting body cells against oxidative stress (it is an important component of antioxidant enzymes).  It also supports normal thyroid function. And … just like other trace minerals, it plays an important role in supporting the cells and tissue of the immune system.

Research suggests that maintaining an optimal selenium status helps support adaptive immunity. Optimal selenium intake contributes to T cell proliferation, NK cell activity, and innate immune cell functions. In elderly individuals, the dietary intake of selenium-rich foods or supplementation may help with supporting immune defences.

Although selenium cannot prevent ill health, dietary selenium intake and selenium status is an integral part of supporting immune system function.

Food supplements should not be used instead of a varied balanced diet and a healthy lifestyle. If you are pregnant, nursing, taking any medications or have any medical condition, please consult your healthcare practitioner before taking any food supplement.
