- Multiple Sclerosis
- Rheumatoid Arthritis
The Sunlight, Nutrition And Health Research Center reports that the prevalence of diabetes, multiple sclerosis, and rheumatoid arthritis increases as latitude increases. This suggests that lower exposure to sun light and associated decreases in vitamin D synthesis may be involved in the development of these diseases.
Vitamin D and High Blood Pressure (Hypertension)
There is some evidence that decreased vitamin D levels are associated with higher blood pressure.
In one study, supplementing with both calcium and vitamin D was associated with a modest decrease in blood pressure compared to calcium alone.
