Are YOU struggling to conceive? Vitamin D supplements can REDUCE fertility – Express.co.uk
Dr Rasmussen said: “Fertile women are often found to have low vitamin D levels, which are associated with low birth weight, reduced fertility and adverse pregnancy outcomes.
“Our aim was to look at the effects of vitamin D supplements on these areas in women with low levels of vitamin D.”
The 193 women were aged between 20 and 40, were planning pregnancy and had levels of 25-hydroxyvitamin D – known as 25OHD – below 50 nmol/L, which is bordering on insufficient levels of vitamin D.
“Before conceiving, they were allocated to groups, one being given a 70mcg daily supplement of vitamin D3 and one a 35mcg daily dose, with matching groups given placebos,” said Dr Rasmussen.
