Pregnant women are being advised to take Vitamin B3 to help prevent miscarriages and birth defects.
Australian research on mice has found miscarriages are sometimes caused by gene mutations in a molecule called NAD and the way to fixing them, is by increasing levels of Vitamin B3.
Professor at the Victor Chang Cardiac Research Institute Sally Dunwoodie told Mike Hosking more research needs to be done to determine just how much B3 is needed.
"What we would recommend is that pregnant women, in the end stage of pregnancy take a pregnancy multivitamin and that's has a standard amount of vitamin B3 and that's the best advice we can give at the moment."
Dunwoodie said they still have some way to go to figure out just how much Vitamin B3 someone needs to take.
"It depends how deficient you are in NAD and therefore how much B3 you need to raise those levels of NAD again."
