Vitamin D is actually not a true vitamin, but a precursor to steroid hormones. It plays a vital role in calcium regulation, immune modulation and inflammation in the body. Vitamin D deficiency is common in the winter months from October to March, particularly in Canada where we are far from the equator. Deficiency occurs because Vitamin D is synthesized by the skin from exposure to ultraviolet light from the sun. The most active and well utilized form of Vitamin D is D3 or Cholecalciferol. Most supplements are now found in the form of Vitamin D3 and are sourced from either fish oil or the oil from sheep wool that is collected in the shearing process. Make sure you check your supplement to be sure that you are getting the Vitamin D3 form.

 Vitamin D is has several important roles in the body including the following:

- Immune system modulators
- Increased white blood cell activity and stimulation
- Decreased inflammation 

These actions make Vitamin D 3 supplementation very important in the prevention and treatment of influenza and colds this season. You can get your Vitamin D levels tested through your Naturopathic or Medical Doctors. The best test is 25-hydroxy-Vitamin D and involves having a blood draw to obtain a sample.

Dr Watkins can assess and recommend your individual Vitamin D3 needs based the results on your blood testing and medical history including immune function, autoimmune conditions and metabolic disorders including diabetes, osteoporosis or osteopenia, seasonal affective disorder, menopause onset and hormone balance. High levels of calcium supplementation may need to be monitored and adjusted when used in conjunction with high dose, long-term Vitamin D3 therapy to prevent excessive calcium deposition in the body. Furthermore, digestive concerns where the emulsification and breakdown of fats is inhibited need to be considered for optimal Vitamin D3 absorption in the small intestine.

Children can also benefit from Vitamin D3 supplementation, particularly in the winter months. They require different dosing than adults and this should be done with the consultation of a qualified health care practitioner.
