Vitamin D is produced naturally when our skin is exposed to strong sunlight. However, in the northern hemisphere this type of natural light is not available during much of the year, therefore Canadians are at a greater risk of deficiency. Other at-risk groups include seniors, people with darker skin, vegans and those on a low protein diet. Health professionals in Canada estimate that increased vitamin D blood levels would reduce incidence of a variety of conditions, including osteoporosis, cardiovascular diseases, multiple sclerosis, pneumonia. Adequate levels vitamin D are important for the prevention of many chronic health conditions.

Vitamin D plays an integral role in bone health, promoting our absorption of both calcium and phosphorus. For this reason, it is commonly used in the prevention and treatment of osteoporosis.
We are understanding more and more the importance that vitamin D is playing in supporting immune function. Vitamin D has the ability to modulate the immune response, rather than simply strengthen it. In cases of immune dysregulation (autoimmune disorders, psoriasis) it serves to balance the response, therefore decreasing the dangerous over-reaction to our own cells and tissues that is seen in many of these conditions. Research studying the use of vitamin D in influenza and various respiratory tract infections, has also showed some promising results. It is now considered one of the top supplements to use during cold and flu season to ward off the offending viruses and bacterium. Vitamin D deficiencies have been associated with an increased risk of influenza, as well as the common cold. The fat soluble vitamin has been shown to dramatically stimulate the expression of potent anti-microbial peptides, which exist in neutrophils, monocytes, natural killer cells, and in epithelial cells lining the respiratory tract. These cells play a major role in protecting the lung from infection.
