The Epidemic of Vitamin D Deficiency? Seattle Naturopath Dr. Diane Lee

Friday, June 25, 2010

People are very confused about vitamin D, with good reason! For years it was thought of to be a very toxic vitamin that you shouldn’t to too much of. The recommended daily allowance was set at 400IU per day which was the amount necessary to prevent rickets (a brittle bone disease). Research is now showing that supplementation should be somewhere between 2000-4000IU/day depending on the health conditions and current vitamin D status.


It is my recommendation that everyone get their vitamin D levels checked. While the test is not cheap, it will provide invaluable information to preventing multiple chronic diseases including:


·      Osteoporosis

·      Cancer

o   77% risk reduction of ALL cancer risk in postmenopausal woman that were supplemented with calcium and vitamin D (Am J Clin Nut)

o   50% of colon cancer could be prevented by maintaining vitamin D blood levels of >34ng/ml (Nutrition Review, 2007)

o   Reduction by up to 50% of breast cancer risk for people who maintain a vitamin D level of >52ng/ml (Nutrition Reviews, 2007)

o   Reduction by up to 50% of type 1 diabetes in people who maintain a vitamin D level of >34ng/ml (Nutrition Reviews, 2007)

o   Reduction of 20% of ovarian cancer of people that maintain a vitamin D level of >40ng/ml (Nutrition Reviews, 2007)


·      Heart disease

·      Inflammation

·      Immune System


We all know that we require the sunlight to produce vitamin D in the body, and that while food supplies minute amounts of vitamin D it is really the sun that we need to reach optimal vitamin D levels.  So here is the dilemma, we know that sun exposure can increase our risk factor for skin cancer so we avoid the sun but we also know that low vitamin D levels will contribute to chronic disease. In fact, research has shown that people with skin cancer have the lowest rate of all other types of cancers. So what are we saying, you should get skin cancer…NO! We are saying that you need optimal levels of vitamin D!!
