Why Is Vitamin D Important?

Our bodies naturally produces Vitamin D when sunlight is absorbed by our skin. In Canada, much of the northern hemisphere there is no natural light source available for much of the year. SISU developed Vitamin D to help prevent Vitamin D deficiencies and health problems associated with low levels of Vitamin D. Health professionals in Canada believe more Vitamin D in the blood of Canadians will reduce a number of conditions including cancer, osteoporosis, multiple sclerosis, cardiovascular disease, and pneumonia.
