The Importance of Vitamin D in Winter

What is Vitamin D?

Vitamin D is a fat-soluble vitamin that is imperative in the health of our bones, teeth, immune system and mood regulation.

Where do we get Vitamin D?

The active form of Vitamin D is known as cholecalciferol (D3) and is produced by the body when sunlight is absorbed through the skin. For this reason, in Canada people are often found to be deficient in vitamin D. A typical year in Canada only has one season that provides enough sunlight and heat to ensure adequate amounts of skin exposure to the sun. The rest of the year is mainly spent indoors or in long sleeves, pants, jackets with only the face and hands in direct sunlight.

As mentioned above, there are important uses of vitamin D as it pertains to our health. If we aren’t getting adequate vitamin D absorbed through the skin for 50-75% of the year, then the supplementation of active vitamin D3 can be a beneficial option to maintaining optimal health.

Food Sources

Very little vitamin D is obtained from food though small amounts can be found in the following foods: Salmon, sardines, egg yolk, shrimp, and some fortified foods such as milk, yogurt and orange juice.
