It’s thought that a lack of the vitamin can lead to the development of serious birth defects in foetuses.
Many countries have now added it to flour products to ensure pregnant women get as much as they need.
But the Swedish Food Agency has decided against this, saying there are also studies that suggest folic acid can stimulate tumors. Instead they say that all women between the ages of 15 and 45 will now be able to get tablets containing the vitamin free of charge.
Critics aren’t impressed though, pointing out that folic acid is needed very early in pregnancies, that not all pregnancies are planned, and by the time a woman realises she is pregnant it could be too late.
