Epidemiological studies have shown that relatively high doses of omega-3 fatty acids that are found in oily fish and fish oil supplements have a positive effect on neurodegenerative diseases such as sclerosis, but the underlying mechanisms are not known. A mouse study reveals that one particular omega-3 fatty acid is able to control the immune defense and regulate the inflammatory processes in the central nervous system.

It is common knowledge that too much sun exposure can cause skin cancer. On the other hand, lack of sunlight is also a problem. If you expose yourself to plenty of sunlight during your childhood years it lowers your risk of developing multiple sclerosis later in life, according to a study from University of California and Australian National University. The reason why sunlight protects against multiple sclerosis and a number of other illnesses is that the sun is our most important source of vitamin D a nutrient with multiple functions in the body. Therefore, it is essential to get plenty of sun as long as you avoid getting a sunburn. For people living at northern latitudes, it’s important to follow the official guidelines for vitamin D supplementation to make sure that we have enough vitamin D in our body at all times.

Vitamin B12 is important for the development and function of our central nervous system. In the past decades, science has also found similarities between sclerosis and the neurological symptoms that occur in people who lack vitamin B12. In a new study that is published in Cell Reports, scientists have found the molecular relation between vitamin B12 and the function of supportive brain cells.

There is a link between vitamin D deficiency and sclerosis. However, only few studies show whether vitamin D supplements can stop further progression of the disease. A new placebo-controlled study of rats with advanced sclerosis has looked closer at the connection. The study, which is published in Nutrients, shows that vitamin D supplementation counteracts oxidative stress, chronic inflammation, and other processes that are involved in the neurological damage seen with this disease. It is important that vitamin D supplementation aims at optimizing blood levels of the nutrient, which requires higher doses than officially recommended. It also requires enough magnesium to help activate vitamin D and support the nervous system.
