New meta-analysis: vitamin D levels low in people with Alzheimer’s and Parkinson’s

Posted on: April 21, 2013   by  Brant Cebulla


A new meta-analysis published in the journal Nutrition confirms that people with  Alzheimer’s and Parkinson’s have lower vitamin D levels than healthy controls.

Both Alzheimer’s and Parkinson’s have become of greater interest in public health in recent years, due to increasing life expectancy, an overall larger elder population and subsequent increase in incidence of both diseases. Vitamin D has been proposed to play a role in both. Many studies have looked at the vitamin D levels of people with these diseases and compared them to healthy controls and have found low levels. Furthermore in a recent high quality study, a randomized controlled trial showed that vitamin D may be of some help in Parkinson’s. Similar studies are underway for Alzheimer’s.

    Thank you, Brant, for the excellent article. It gives me hope.

    My beloved father died 16 years ago–a victim of Lewy Body disease at age 80. My mom and I watched his body and mind disintegrate over the course of five years. It was horrible. And, I worry daily that this too will be my fate.

    I’ve attached a wonder article by Maria Shriver on the subject of Alzheimer’s disease.

    As quoted from her article:

    “What can we do to prevent Alzheimer’s? Do lifestyle changes really help? Should we all be hitting the treadmill, drinking tea, doing crossword puzzles, taking Omega-3 and Vitamin D?”

    Well, I for one will be taking my Vitamin D3 (as well as sunning appropriately).


    Be well!

    Clearly people diagnosed with Alzheimers are likely by reason of their circumstances, to be deprived of sun and suffer an insufficient diet. I don’t think anything can be drawn from their low Vit D levels.
    It looks as if we need studies linking low vit D levels with subsequent development of ASD and Parkinsons.
    I shall of course continue to take my winter D.
