What are Folic acid and folate?

“Folic acid” and “folate” are often used synonymously. However, they are very different.

Folate is the natural and pure form of Vitamin B9, found in abundance in green leafy vegetables.

 Folic acid, a synthetic form of Vitamin B9 is added to processed foods such as breakfast cereals and is created as health supplements.

Why do women need Folic acid? 

Before and during pregnancy

Before planning pregnancy, women need to maintain good health by following a healthy diet, regular exercise, etc. Hence, Folic acid is an important supplement that women need to consume before, during and after pregnancy. Folic acid helps in the constant reproduction of cells in our organs.  

Consumption of Folic acid before planning for pregnancy helps prevent congenital disabilities of the foetus and prevent miscarriages. It prevents the young child from developing serious and critical illnesses like neural tube defects such as spina bifida.

Pregnant women need to consume at least 600 mcg of Folic acid every day to ensure the baby’s proper growth and development.  

To keep the blood healthy – Promotes red blood cells formation and growth

Pregnant women are more prone to folate-deficiency Anemia. Therefore, to prevent such disorders, Folic acid intake is necessary.

Benefits of Folic acid

Healthy pregnancy

Folic acid aids tissue and cell growth in the foetus and protects the baby from congenital disorders and birth defects like neural tube defects and other deficiencies. It also safeguards the mother-to-be from pregnancy-related complications, such as miscarriages.
