High levels of vitamin D could lower the risk of Parkinson’s disease. Low sunlight leads to a chronic lack of the nutrient. In Finland, first hypothesized that Parkinson’s may be caused by a continuously inadequate vitamin D status leading to a chronic loss of dopaminergic neurons in the brain.

According to the researchers, Vitamin D is supplied chiefly by the sun’s ultraviolet rays and a small range of foods play a role in bone health and may also be linked to cancer, heart disease and type 2 diabetes.

The role of vitamin D to Parkinson’s risk is still unexplained but said the nutrients has been shown to exert a protective effect on the brain through antioxidants activities, regulation of calcium levels, detoxification, modulation of the immune system and enhanced conduction of electricity through neurons.
