Its not all in your head: Vitamin D, the mind body connection


Our growing awareness of the mind-body connection continually points to the importance of nutrition not just for physical health, but also for mental and emotional wellbeing. Vitamin D is one such nutrient which serves an essential role in the body including supporting the immune system, bone development, and mental health.

Monitoring vitamin D levels during pregnancy is a helpful screening tool, especially since recent data suggest that doses of 4000IU in the second and third trimester may minimize complications such as gestational diabetes and preeclampsia.(1) Another study found that deficiency/insufficiency of vitamin D levels at 13 weeks gestation were associated with depressive symptoms at 16 weeks postpartum. (2)  vitamin D has also been found to reduce inflammation. In particular one study found that women supplemented with vitamin D (400IU/day) showed lower levels of inflammatory markers when compared to the placebo group. (3)

In addition to supporting your emotional wellbeing, vitamin D plays an important role in the development of your baby’s bone and hormonal health. People who are prone to vitamin D deficiency include those living in northern climates, people with darker skin pigmentation, those who consume a low fat diet or are taking steroids.

While small amounts of vitamin D can be obtained through fish, eggs and cod liver oil, sunlight remains the primary source of this essential nutrient.We first encourage increasing dietary sources of foods rich in vitamin D:

  1. Sunlight
  2. Cod liver oil
  3. Sardines
  4. Salmon
  5. Grass fed (full fat) dairy
  6. Eggs
  7. Mushrooms like Shiitake

When supplementing, it is important to periodically have your levels tested to make sure they are within a normal range. Combining Vitamin D with Vitamin K2 may provide even better protection of important systems in the body. We like this formula for that reason. Talk with you midwives if you are interested in having your vitamin D levels tested.
