Vitamin D

Vitamin D is a fat-soluble vitamin that is found naturally in some foods, and can also be made in the body after exposure to ultraviolet (UV) rays from the sun.

Autoimmune diseases like MS and type 1 diabetes are diseases in which the immune system mistakenly attacks the body’s own tissues, or harmless substances that enter the body. Vitamin D controls calcium levels in the blood; important for strong bones, muscles and overall health. 

Some studies have suggested a link between Vitamin D deficiency and autoimmune diseases such as MS. This possible link might also explain the increasing prevalence of autoimmune disease among those living far from the equator, where there are lower levels of winter sun.

There is ongoing research internationally evaluating the link between low Vitamin D levels both being a risk factor for developing MS and also as a potential treatment to prevent people who have had a single attack converting to MS.

Most people diagnosed with MS will have their Vitamin D level checked by their neurologist and be recommended supplements. We recommend you discuss this with your neurologist and/or speak with one of our MS nurses on 9365 4888 or by sending an email.
