Vitamin D May Not Offer Protection Against Neurological Diseases? (NHS Choices / Nutritional Neuroscience / BJPsych Open)


A recent systematic review of studies into the role of Vitamin D exposure levels / deficiency or supplementation in four neurodegenerative diseases (Alzheimer’s Disease, Motor Neurone Disease, Multiple Sclerosis (MS) and Parkinson’s Disease) found little conclusive evidence for any supposed neuroprotective benefits from Vitamin D.

Oddly, sunlight / ultra-violet (UV) exposure, independent of Vitamin D production, may be protective against multiple sclerosis. Vitamin D supplementation appears not to be an effective substitute for UV exposure in providing any protection against neurodegenerative diseases.

More research is required.
