Top Vitamins To Take Whilst Pregnant?

Pregnancy is a critical time for both mother and the baby and following a healthy diet reflects on the health and development of the child. During pregnancy, women require more nutrients, vitamins and minerals (1). In fact, in the second and third trimester of pregnancy, the body requires up to five hundred more calories during the day (2). Poor eating habits and excessive weight gain can increase the mother’s risk of developing gestational diabetes and complications of pregnancy and birth (3).

The ideal diet for an expectant mother should be providing her with ample amounts of protein, carbohydrates, healthy fats, minerals and vitamins.


Vitamin B9 (folate)


This vitamin plays an important role in the synthesis of DNA, the production of red blood cell and the growth and development of the foetus (4). Folic acid is a synthetic form of folate which is often seen in supplements, once consumed the body converts it into the active form of folate, L-methylfolate. Experts recommend that pregnant women should be consuming roughly 600ug of folate or folic acid on a daily basis to reduce any risks of neural tube defects and congenital abnormalities including cleft palate and heart defects (5). A review of five studies which had over six thousand pregnant participants, found that daily supplementing with folic acid was associated with a reduced risk of neural tube defects and no negative side effects occurred (6).

Although it is possible to consume enough folate through diet alone, many women still are not eating enough folate-rich foods which makes supplementation a necessity (7).

Foods with a good source of Vitamin B9: Asparagus,Leafy Greens, Broccoli and Brussels Sprouts


Vitamin D


This vitamin is fat soluble and is understood to be important in immune function, bone health and in cell division. Studies have found that deficiencies in vitamin D are linked with an increased risk of emergency caesarean sections, preeclampsia, premature births and the development of gestational diabetes (8). Currently, it is recommended that pregnant women consume 600 iu of vitamin D daily, however this is disputed by other experts who suggest that vitamin D intake should be higher (9).


Foods with a good source of Vitamin D: Vitamin D can occur naturally from sunlight exposure, but you can also get Vitamin D from fortified foods including yoghurts, milk and certain cheeses.



Vitamin C


A recent review carried out in 2015 found that routine supplementation of vitamin C during pregnancy was associated with a thirty-six percent reduction in cases of placental abruption in along with a significant reduction in cases of pre-labour rupture of membranes (PROM) (10).




Foods with a good source of Vitamin C: Red, Peppers, Oranges, Kiwi and Acerola Cherries.



Vitamin B6 (Pyridoxine)


Vitamin B6 is known to be important for several metabolic processes within the body, which include the development and functioning of the nervous system. It was previously suggested that consuming vitamin B6 on a regular basis played a role in the prevention of pre-eclampsia and even preterm birth, however, more recent reviews on the has found that there is insufficient evidence to claim any benefits or harm. Instead, routine vitamin B6 supplementation has been shown to provide relief from pregnancy-related symptoms of morning sickness (13).


Foods with a good source of Vitamin B6: Avocado, spinach and a medium russet baked potato.
