The strong evidence to support the importance of Vitamin D and its benefits for our health continues to gather momentum – and now another recent study claims that a lack of Vitamin D may be a direct cause of multiple sclerosis (MS).

Previous studies have suggested an association between lower Vitamin D levels and a higher risk of MS. But now scientists have demonstrated a genetic correlation that points strongly to a causal link.

The findings may help explain why rates of MS, a potentially disabling auto-immune disease that damages nerve fibres, are higher in Northern Europe, which have fewer sunny days, especially in the winter months. The primary source of Vitamin D is via exposure to sunshine.

The discovery may have important public health implications since so many people have insufficient levels of the essential vitamin, researchers say.

Nutrition and Vitamin D

Food sources of Vitamin D include oily fish (such as salmon, sardines and mackerel), butter and eggs, although studies show that to ensure we’re receiving optimum levels, a Vitamin D supplement is vital, especially in the coming winter months. You should always seek professional advice before taking any supplements.
