If you have low levels of vitamin D, or indeed a vitamin D deficiency, a loss of bone density may occur that could further lead to fractures or rickets; a rare disease in children that softens their bones and makes them bend.

While studies are inconclusive at this present time, there is more and more research being carried out that suggests vitamin D insufficiency may relate to higher levels of Anxiety in some individuals.
