General Information

Vitamin D is crucial to the building and maintenance of healthy bones and teeth. The recommended form of vitamin D is vitamin D3, known also as cholecalciferol. Calcium, the primary component of bone, is only properly absorbed by your body when vitamin D is present. Vitamin D is created within the body when direct sunlight converts a chemical in your skin into an active form of the vitamin. There are not many foods that contain vitamin D, but you can find it in fortified milk, fortified cereals, and fatty fish, like salmon, mackerel, and sardines. Unfortunately, most people do not get the necessary amount of vitamin D. Therefore, supplementation is needed. Vitamin D3 is the perfect supplement as it is the natural form of vitamin D that your body makes from sunlight.

Roles of vitamin D within the body, as stated by Medical News Today, include:

  • – Support of the immune system, brain, and nervous system
  • – Regulation of insulin levels, aiding in diabetes management
  • – Support of lung function and cardiovascular health
  • – Influence the expression of genes involved in cancer development

As previously stated, most people do not get the proper amount of vitamin D. There are many different factors that affect the amount of vitamin D that your skin produces. These factors include the time of day, season, latitude, skin pigmentation, location, and lifestyle. Someone living in a state, such as Florida, would produce more vitamin D compared to someone living in a state with less sunshine. It is said that sunscreen, while important, can decrease vitamin D production because it blocks the UVB rays needed.
