Think vitamin D is only for bones? THINK again.
This is Sandra Tsing Loh with the Loh Down on Science.
Could low vitamin D levels in older adults be an early predictor for dementia, later in life?
Enter Martin Mulligan and team from the University of Galway. They measured vitamin D levels in over four hundred dementia-free participants around age forty. Roughly sixteen years later, they took brain scans to look for early signs of dementia.
Results? Higher vitamin D levels were linked to fewer early signs associated with dementia risk. Taking vitamin D early on may protect the brain from the onset of dementia later in life.
So, take Vitamin D – For your bones…AND your brain! (… AND YOUR BONES)
