Nutritional gains? If your nose is perma-snotty or you’re trying to conceive, pay attention. Selenium boosts immune system function and is a key player in egg formation and fertilisation. But 47% of women have intakes below the LRNI, according to the NDNS 2018. Poor show.
Where’s it at? Brazil nuts and eggs.
Dose? Women should aim for 0.06mg a day (0.075mg if you’re breastfeeding), which you’ll get by eating three Brazil nuts a week (not per day, as many think), or in a daily multimineral. But beware: too much can lead to selenium poisoning, symptoms of which include hair loss and skin and nail discoloration. No thanks.
