Vitamin D Deficiency Increases Risk of Disease
Low levels of Vitamin D can lead to a variety of serious health problems.
1. Chronic diseases
- Heart disease
- Infectious diseases
- Type I diabetes
- Rheumatoid arthritis
- Crohn’s disease
- Multiple sclerosis
2. Increased risk of dying from certain cancers
Causes of Vitamin D Deficiency
- Kidney disease/failure – kidneys inability to convert Vitamin D into its active form.
- Digestive tract problems (Crohn’s disease, cystic fibrosis, celiac disease) – inability to absorb vitamin D.
- Diet low on vitamin D rich foods.
- No or very limited exposure to sunlight daily.
- Dark skin tone – dark skin requires longer exposure to sunlight to produce vitamin D. An African American person may need 6 to 10 fold more time in the sun as compared to a white person in order to produce the same amount of Vitamin D.
- Sun screens, pollution, shade– a sunscreen with a SPF of 8 or more reduces the ability of the skin to form vitamin D by more than 95%. Complete cloud cover, shade and pollution reduce solar UVB affect (energy) by 50%.
- Age – the skin of elderly people typically produces only about 25% of Vitamin D3 as compared to the skin of a young person.

How The Body Makes Vitamin D
Vitamin D is, in fact, a hormone. It is produced in the skin from pro-vitamin D3 which is derived from cholesterol. Cholesterol is a precursor for most hormones in your body.
Type B ultraviolet rays (UVB) from the sun act on pro-vitamin D3 and convert it into pre-vitamin D3, which is then converted into Vitamin D3. Vitamin D3 then leaves the skin and gets into your blood stream where it is carried on a special protein called a vitamin D-binding protein.
Through blood circulation, Vitamin D3 reaches various organs in your body. In the liver, Vitamin D3 undergoes a slight change in its chemical structure. Then it is carried through the blood stream to the kidneys where it goes through another change in its chemical structure – active form of Vitamin D. It gets in the blood stream and goes to various parts of the body and exerts its actions.
