Why is vitamin D important?

The majority of the vitamin D we need is synthesized when the sunlight triggers a reaction in your skin. This time of year most people are covered up to keep warm in the cold weather. In addition, in many states the sun is at an angle in which vitamin D may not be sufficiently synthesized. Many Americans are deficient in this vital vitamin and it is important to check with your doctor if you feel you may be deficient.

The major function of vitamin D is to promote calcium absorption in the gut and maintains adequate serum calcium and phosphate concentrations. There are studies that suggest that some athletes are not getting enough vitamin D. Vitamin D is in dietary sources such as fish, eggs, and fortified milk. The sun also contributes significantly to the production of vitamin D.

Here are a list of the health benefits of vitamin D:

1) Bones: Together with calcium, vitamin D is essential for bone growth and bone remodeling.

2) Heart Disease: Low levels of vitamin D could indicate an increased risk for heart disease. In addition, vitamin D may provide protection from hypertension in patients with low vitamin D levels.

3) Cancer: Having adequate levels of vitamin D could lower the risk of developing cancer. There is evidence indicating that vitamin D may have a protective effect against some cancer such as colon cancer.

4) Neuromuscular and immune function: vitamin D is an important immune system regulator. Adequate vitamin D is necessary to decrease the susceptibility to infectious disease such as the cold and flu.
