Role of Vitamin D
Vitamin D is obtained by the body through food and skin synthesis under the influence of sunlight. This vitamin helps in the healthy developing of the skeleton. For these reasons, during the winter season, when the solar radiation is smaller in intensity, it`s recommended to supplement vitamin D intake, including by the expecting mothers without health issues. Even in larger amounts than the normal dose, it were found that there are no side effects on the pregnant woman or the fetus. A recent study performed at the Medical University of South Carolina showed exactly the opposite. Experts claim that a daily dose of 200 units of vitamin D can only have beneficial effects on the mother and baby. Researchers have monitored 350 women found in the weeks 12 to 16 of pregnancy, whom they divided into 3 groups. One of the groups has received 400 units of vitamin D each day, while the second group has received 2.000 units of vitamin D every day and the third group received 4.000 units every day. At the end of the study, no side effects were seen in any of the 3 groups.
Daily Recommended Dose of Vitamin D during Pregnancy
Generally speaking, this dose is established together with the doctor that monitors your pregnancy, but it`s thought that 5 mcg per day is enough for expecting mothers.
Still, this may differ from one pregnant woman to another depending on:
- Skin color.
- Sun exposure.
Which is the optimal dose of vitamin D? The daily recommended dose is of 5 – 10 mcg (more at those over 50 years old). Mainly, experts recommend to adults with ages between 19 – 50 years around 5 mcg per day. This recommendation is available for pregnant women or breastfeeding women as well. Adults over 50 years need 10 mcg per day. Parents are advised to give to children 2 cups of milk per day (a cup of milk is equal with 2.5 mcg of vitamin D).
Where Do We Get Vitamin D?
Your body produces enough vitamin D most of the times by sun exposure in the periods of April to October, between 11.00 and 15.00, depending on where you live. The further away you live in the north, the less time the sun stays in the right angle to allow the body to produce vitamin D.
Try to expose at least your face and forearms to the sunlight for at least 20 minutes per day, without blocking the sun during summer. This will build enough amount of vitamin D for the long months of winter. In any case, make sure you protect your skin with sunscreen and cover it before it gets red or burn.
The best sources of vitamin D are fatty fish, such as: salmon, mackerel and sardines. You should consume at least 2 portions of fish per week, among which one of them should be fatty fish. Red meat, beef liver, soybeans, egg yolks, mushrooms, orange juice, Swiss cheese or milk also contain our vitamin.
Certain types of margarine (which actually aren`t recommended) and breakfast cereals are enriched with vitamin D, so check the nutritional information on the package.
During winter, the sun isn`t at the right angle to produce rays that can stimulate the vitamin D production for our skin. So, we need to get this vitamin from the food we consume to supplement the reserves of our body.

Although most women had a low level of vitamin D, the ones who suffered of preeclampsia had a much lower level of this vitamin than the other women.
