Vitamin D3 during pregnancy

Vitamin D3 – what role does it play in the body?

Vitamin D, like vitamins A, E and K, is a fat-soluble vitamin. This means that their absorption depends on the diet one eats. The presence of fats in daily meals is necessary for proper absorption. The main role of vitamin D3 in the body is to regulate calcium and phosphate metabolism and maintain adequate bone mineral density. It enables the normal development of the foetal skeletal system. It also influences the immune system. During pregnancy, vitamin D is thought to play a role in the occurrence of recurrent miscarriages or is a protective factor in pre-eclampsia.

Vitamin D3 doses during pregnancy

Vitamin D3 is synthesised in the human skin when it is exposed to UV radiation. In our latitudes, this is possible between May and September if you expose yourself to the sun for at least half an hour without using filters. However, it is well known that UV filters are indispensable, especially for pregnant women, as they prevent sunburn or discolouration. Excessive sun exposure can promote the development of squamous cell carcinoma. For this reason, supplementation with vitamin D3 in a dose of 1500-2000 IU is recommended for all pregnant women. In overweight women, this dose can be increased to 4000 IU. However, taking higher amounts is not recommended due to side effects.

Vitamin D products

Besides sun exposure and taking vitamin D in tablet form, you can turn to foods that contain this vitamin naturally during pregnancy. Among other things, it is found in fatty fish such as herring, mackerel and salmon, as well as in egg yolks. Vitamin D is also found in milk and fatty cheese.
