A lot of research has been published recently on the importance of vitamin D.
The research reviewed here investigated vitamin D levels and its association to Parkinson disease (Knekt P, et al. 2010).
The follow-up period was 29 years and serum 25-hydroxyvitamin D level (the most common way of testing vitamin D) was determined from frozen samples stored at baseline.
The results showed that individuals with higher serum vitamin D concentration had a reduced risk of Parkinson disease.
This is one more reason to be sure you get enough vitamin D.
It is very common to have low levels of vitamin D because of inadequate sun exposure or regular use of sunscreen.
Taking between 1000 IU to 2000 IU of vitamin D3 daily will help. It is not recommended to take huge amounts of vitamin D, since vitamin D is not only a vitamin but also a hormone the body regulates. More is not always better.
You can safely take 1000 IU-2000 IU daily of vitamin D, but it is recommended to have a vitamin D test before taking higher amounts.
