Vitamin D is Not Really a Vitamin

Let’s review some data on Vitamin D. Vitamin D is not really a vitamin but acts more like a hormone. There are vitamin D receptors in bone, intestines, the brain, breast tissue, prostate and white blood cells. Vitamin D is formed in the skin from exposure to sunlight but these days with judicious use of sunscreen and weather changes, this method is inefficient and supplementation is often needed. The active form of D increases calcium and phosphorous absorption in the intestines, increases calcium deposition in bone, has anti inflammatory effects and has neurotransmitter functions.

Therapeutic effects of Vitamin D are seen in cardiovascular disease, hypertension, diabetes, osteoarthritis, multiple sclerosis, depression, epilepsy, migraine and cancer prevention and treatment. For instance, death from heart disease is more common in the winter and in northern latitudes and the risk is twice as high if vitamin D levels are low.
Vitamin D deficiency has been found to be a cause of heart failure. Blood pressure is also higher in the winter, in northern latitudes and with increased skin pigmentation. Patients treated with UV light 3X weekly for six weeks had their blood pressure fall significantly as their D levels increased by 162%!

Low D is also associated with insulin resistance. The diabetes drug Metformin improves insulin sensitivity by 13%. Higher vitamin D status in this study correlated with a 60% improvement in insulin sensitivity. In a study of SAD or seasonal affective disorder, supplementation with Vitamin D had significant improvement of mood. Inadequate exposure to sunlight is associated with many cancers including breast, colon, ovary, prostate, uterus and Non-Hodgkin Lymphoma. 23,000 American lives per year could be saved from a reduction in cancer mortality by supplementing with Vitamin D!

If everyone had a vitamin D level of greater than or equal to 55ng/ml, approximately 250,000 cases of colorectal cancer and 300,000 cases of breast cancer could be prevented annually. This is simple math with a simple solution.

Get your D levels up to par with sunlight, foods and or supplementation. And be a positive happy statistic!
