Vitamin D Deficiency May Predispose Individuals To Parkinson's Disease

July 21, 2010 by  

Vitamin D Deficiency May Predispose Individuals To Parkinson's DiseaseOn the heels of several studies linking vitamin D deficiencies to general cognitive disorders, new research has found that low serum levels of the nutrient may also be partially responsible for the development of Parkinson’s disease.

For the study, Paul Knekt and his colleagues from the National Institute for Health and Welfare in Helsinki, Finland, recruited nearly 3,200 healthy men and women between the ages of 50 and 79, and took blood samples to assess their vitamin D levels.

Over the next three decades, a total of 50 respondents developed Parkinson’s disease.

After adjusting for potential risk factors, the research team found that participants who had the highest baseline vitamin D levels were 67 percent less likely to be diagnosed with Parkinson’s than those with the lowest levels.

The "study provides the first promising human data to suggest that inadequate vitamin D status is associated with the risk of developing Parkinson’s disease, but further work is needed in both basic and clinical arenas to elucidate the exact role, mechanisms and optimum concentration of vitamin D in Parkinson’s disease," wrote Marian Leslie, of Emory University, in an accompanying editorial.

While the researchers have yet to define the mechanism responsible for the apparent protective benefit of vitamin D concerning Parkinson’s disease, they suggest that the nutrient improves brain function through antioxidant activities, regulation of calcium levels and detoxification.

    It would be interesting to know how many of this group had exposure to sunlight versus vitamin D. I would suggest that vitamin D is no substitute for ole Sol.

      Hi James,
      As a nurse, we have found that the general population does not get enough Vitamin D from the sun. Especially as we age, our bodies don’t convert the rays into Vit D as was once thought. Next time you visit your Doc, have him check your Vit D level….I was shocked when I found out mine was only “7″ and it should be 40 or above.

      Hope this helps :)

        Understanding Vitamin D CholecalciferolNew manuscript published by Dr. Cannell: On the Aetiology of Autism The high rate of natural production of vitamin D3 cholecalciferol (pronounced koh·luh·kal·sif·uh·rawl) in the skin is the single most important fact every person should know about vitamin D—a fact that has profound implications for the natural human condition.
        Want to know your vitamin D level? Participate in our Quest / LabCorp Vitamin D Testing Project! Technically not a “vitamin,” vitamin D is in a class by itself. Its metabolic product, calcitriol, is actually a secosteroid hormone that targets over 2000 genes (about 10% of the human genome) in the human body. Current research has implicated vitamin D deficiency as a major factor in the pathology of at least 17 varieties of cancer as well as heart disease, stroke, hypertension, autoimmune diseases, diabetes, depression, chronic pain, osteoarthritis, osteoporosis, muscle weakness, muscle wasting, birth defects, periodontal disease, and more.
        Vitamin D’s influence on key biological functions vital to one’s health and well-being mandates that vitamin D no longer be ignored by the health care industry nor by individuals striving to achieve and maintain a greater state of health.
        Sunshine and Your HealthIf well adults and adolescents regularly avoid sunlight exposure, research indicates a necessity to supplement with at least 5,000 units (IU) of vitamin D daily. To obtain this amount from milk one would need to consume 50 glasses. With a multivitamin more than 10 tablets would be necessary. Neither is advisable.
        The skin produces approximately 10,000 IU vitamin D in response 20–30 minutes summer sun exposure—50 times more than the US government’s recommendation of 200 IU per day!
        Vitamin D’s Co-factorsVitamin D has co-factors that the body needs in order to utilize vitamin D properly. They are:
        vitamin K2
        a tiny amount of vitamin A
        Magnesium is the most important of these co-factors. In fact, it is common for rising vitamin D levels to exacerbate an underlying magnesium deficiency. If one is having problems supplementing with vitamin D, a magnesium deficiency could be the reason why.
        Read more about vitamin D’s co-factors.
        How To Get Enough Vitamin DThere are 3 ways for adults to ensure adequate levels of vitamin D:
        regularly receive midday sun exposure in the late spring, summer, and early fall, exposing as much of the skin as possible (being careful to never burn).
        regularly use a sun bed (avoiding sunburn) during the colder months.
        take 5,000 IU per day for 2–3 months, then obtain a 25-hydroxyvitamin D test. Adjust your dosage so that blood levels are between 50–80 ng/mL (or 125–200 nM/L) year-round.
        Attention Patients and Health Care ProfessionalsThe Vitamin D Council would like to help patients who are seeking out doctors to work with them as they strive to attain a better state of health through the use of Vitamin D.
        To help these patients, we have put together a Vitamin D Healthcare Professionals database.

        It’s nice to hear from a healthcare professional who isn’t afraid to talk about the benefits of vitamin supplements (quality, that is – not the cheap stuff). I’d be curious to know if you were around MDs who are taught to poo-poo the idea of taking supplements.
        The last time I heard about the current state of medical school(s), American MDs are still being taught to ignore vitamins and anything that ‘interferes’ with the taking of prescription drugs.
        Here’s to your good health, Patty. Up with good health, and DOWN with Obummerno-care.

    We need to send a mega-dose to Washington. They’re screwed up in the head…

  • Gail Blair

    Keep in mind liquid D3 is best!! You only absorb 33% in pill form

    While it’s right to be concerned with Parkinson’s, we must also be on guard to take sufficient doses of Vitamin D to decrease our chances of being diagnosed with cancer.

    • http://?? Joe H.

      that was always a concern of mine. Cancer rates have been on the rise ever since the advent of bleaching flower from grains. When you bleach the flour, you remove the D from them. then you use sun block religeously and you get no benefit from exposure to the sun. Now, I believe we areraising a generation that may be genetically on the low end of normal to begin with. therefore when you remove one more factor from their life it causes them to go way low!! I could be wrong as I am not a geneticist, but I still wonder! It’s kinda like my gout, I get on the high end of normal on my uric acid level and I get severe pain. It happens every time I get up slightly!
