New research from South Australian scientists has shown that vitamin D (also commonly known as the sunshine vitamin) is unlikely to protect individuals from multiple sclerosis, Parkinson’s disease, Alzheimer’s disease or other brain-related disorders.
The findings, released today in the science journal ‘Nutritional Neuroscience’ reported that researchers had failed to find solid clinical evidence for vitamin D as a protective neurological agent.
“Our work counters an emerging belief held in some quarters suggesting that higher levels of vitamin D can impact positively on brain health,” says lead author Krystal Iacopetta, PhD candidate at the University of Adelaide.
Based on a systematic review of over 70 pre-clinical and clinical studies, Ms Iacopetta investigated the role of vitamin D across a wide range of neurodegenerative diseases.
“Past studies had found that patients with a neurodegenerative disease tended to have lower levels of vitamin D compared to healthy members of the population,” she says.
“This led to the hypothesis that increasing vitamin D levels, either through more UV and sun exposure or by taking vitamin D supplements, could potentially have a positive impact. A widely held community belief is that these supplements could reduce the risk of developing brain-related disorders or limit their progression.”
“The results of our in-depth review and an analysis of all the scientific literature however, indicates that this is not the case and that there is no convincing evidence supporting vitamin D as a protective agent for the brain,” she says.
