A few months ago, I told you about two new studies linking Parkinson's disease with a common vitamin deficiency. In both studies, men and women with low levels of B6 in their blood turned out to be about 50 percent more likely to develop Parkinson's disease.

Well, this month, scientists from Finland found another missing piece to the puzzle. Turns out that vitamin D also plays a huge role in whether or not you develop Parkinson's disease.

In this major study that spanned 30 years, scientists followed 3,173 Finnish men and women. During that time, 50 patients developed Parkinson's. And lack of vitamin D stood out as a major factor. In fact, men and women with the lowest levels were three times more likely to get sick compared to the group with the highest levels of vitamin D.

Put another way, men and women who got with plenty of the "sunshine vitamin" over the 30-year-period reduced their risk of developing Parkinson's by an impressive 67 percent.

Scientists believe that vitamin D is particularly important to the substantia nigra, an area of the brain most affected by Parkinson's disease. This area also contains a high concentration of vitamin D receptors.

So while there's still no cure for Parkinson's disease, we've now got three major studies showing the important role nutrition plays. The bottom line? Make sure to take a B-complex and D3 supplement every day! Not only will you chop away at your Parkinson's risk, you'll also boost your overall health!
