Health studies about vitamin D and autoimmune disease by category:

Month of Birth, Vitamin D and Risk of Immune-Mediated Disease: A Case Control Study (2012)

Conclusion: This UK study found that those with autoimmune diseases are disproportionately born more in April (when population vitamin D levels are typically lowest) and less in October (after summer when people’s vitamin D levels are highest).

 

Does Vitamin D Affect Risk of Developing Autoimmune Disease?: A Systematic Review (2012)

Conclusion: This study looked into 76 other studies investigating the association between vitamin D and a variety of autoimmune diseases. This particular investigation of the 76 studies led the researchers to conclude that: “cross-sectional data point to a potential role of vitamin D in autoimmune disease prevention.” Another finding is that autoimmune diagnoses are on the rise in the America, which correlates with the recorded declining vitamin D levels of the American population, and the rise and persistence of the anti-sun and skin cancer scare propaganda of the cosmeceutical-dermatology-industrial-complex.

 

Vitamin D Supplementation and Regulatory T Cells in Apparently Healthy Subjects: Vitamin D Treatment for Autoimmune Diseases? (2010)

Conclusion: 46 healthy men and women were given 140,000 IU of vitamin D once a month for two months. Besides the average vitamin D level increasing from 24 ng/ml to an optimal 58 ng/ml at the end of the trial, the participants also experience a significant increase in their immune system’s regulatory T cells, demonstrating that vitamin D plays a critical role in proper functioning of the human immune system and helps protect against autoimmune disorders.

 

Ultraviolet Radiation and Autoimmune Disease: Insights from Epidemiological Research (2002)

Note: Short, but dense, overview of epidemiological research investigating the associations of vitamin D ultraviolet light with multiple sclerosis, type 1 diabetes, and arthritis. Basically, people who live farther away from the equator have a higher risk for developing these autoimmune disorders.

Inflammatory Bowel Disease

Multiple Sclerosis
