And to answer your question Amrit yes most autoimmune diseases are associated with low levels of Vitamin D and levels are even lower in witner when darkness rules and people spend most of their time indoors.
You still get small amounts of Vitamin D with food but not enough so that's why I decided to start a supplement.
Vitamin D can modulate your immune system and decrease disease severity.
It has anti-inflammatory effect by inhibiting pro-inflammatory T cells such as Th1 and Th17 cells and by causing apoptosis in B cells.
You need to take a supplement on a regular basis for months to see benefit.
