Around 1 in 7 couples in the UK may have difficulty conceiving; this equates to around 3.5 million people. There are many possible causes and risk factors of infertility such, as age, but lifestyle can play a role and certain nutrients that may be deficient in the diet are necessary for supporting fertility including zinc and selenium. When pregnant, your body requires extra nutritional support for your growing baby and for you. It is important to have good levels of a variety of nutrients, in particular Vitamin D3, iron and folic acid. The NHS recommends both 400μg folic acid and a Vitamin D supplement when planning and during pregnancy.
