Sunshine just isn’t Enough

Posted on August 2, 2010 by


There is much in the news about nutrition and what we are missing. Of course, everyone knows about Omega fatty acids, antioxidants, Vitamin C and the Bs … but many don’t realize that they may be lacking in one of the most important nutrients essential to good health.

Are you getting enough?

In a recent release by Osteoporosis Canada, adults younger than 50 should be taking up to 1,000 IU of Vitamin D. Those 50+ should be taking supplements of up to 2,000 IU. Older RDA amounts such as 600IU to 800IU are outdated and not based on properly conducted studies, says the Canadian Medical Association Journal. Interestingly, a European study found that doses of 2000 to 3000 IU could reduce annual health care costs significantly. In Canada, however, the guidelines remain that 2000IU is the safe upper intake level; higher doses require medical supervision.

Our bodies do manufacture Vitamin D3 upon exposure to sunshine but the levels of UVB radiation in many Northern countries is so weak during the summer, the body makes no Vitamin D3 at all. Populations spent much of their time indoors – year round – in homes, offices, and cars. Even at the height of summer, people are not getting enough valuable sunshine DAILY to manufacture adequate Vitamin D levels. Supplements and fortified foods are the best way to boost intake.

Vitamin D is critical to good health. Deficiency is reported to exacerbate (and perhaps even precipitate) muscle weakness, fractures, osteoporosis, autoimmune disease, cardiovascular disease and more. Some evidence has been found that Vitamin D may reduce the incidence of some cancers and Type-1 Diabetes. Reasons enough to get your D3 today and take it every day!
