Why do pregnant women need folate?

Pregnant women require an increased amount of folate for proper foetal development as folate is necessary for healthy cell division. Low folate levels may lead to neural tube defects in the developing foetus.

Are folate and folic acid the same thing?

Vitamin B9, folic acid, and folate are often used interchangeably. While folate and folic acid are similar, there are differences. Folate is a water-soluble B vitamin, so the body can't store it, and we need to ingest it through the foods we eat. Most people should be able to get the amount they need by eating a varied and balanced diet. Folic acid is a synthesised version of folate produced in a laboratory and found in supplements and fortified foods such as cereals.
