What is vitamin D?

Vitamin D refers to a group of fat-soluble vitamins (vitamins that are absorbed along with dietary fat and can be stored in the body’s fatty tissue). Vitamin D is naturally found in some animal products, such as the flesh of fatty fish. Small amounts can also be found in beef, liver, cheese, and egg yolks. However, the amount of vitamin D found in these foods is dependent on the animal’s diet. This form of vitamin D is referred to as vitamin D3.

Vitamin D can also be found in mushrooms. However, the form of vitamin D found in mushrooms is referred to as vitamin D2. Research distinguished that vitamin D2 and vitamin D3 have equal health benefits in the recommended dosages, however their actions may vary slightly at high doses – when the impact of vitamin D2 is less potent. Moreover, vitamin D3 tends to be the form in which many individuals are deficient in.

Why is vitamin D important in pregnancy?

Since vitamin D helps regulate the amount of calcium and phosphate found in the body, is helps regulate the amount in our baby’s body too. Calcium is needed to help strengthen the baby’s rapidly developing bones and teeth, as well as boost muscle, heart, and nerve development. Like calcium, phosphate also helps strengthen the baby’s bones. It is also incredibly important for many bodily functions such as clotting, kidney function, tissue and cell repair, muscle concentrations and a normal heart rhythm.
