A recent study suggests that high levels of urate in the blood stream can slow the progression of Parkinson's Disease. Urate is a salt derived from uric acid, a natural substance in the body. High levels of urate or uric acid can lead to other conditions, such as gout.

Previous research noted that people with a higher natural level of urate had a reduced risk of developing Parkinson's. For this study, researchers followed 800 people with mild Parkinson's symptoms. Those who had higher levels of urate were about half the risk of their symptoms worsening. At the end of the study, none of the patients with naturally high urate levels required other medications to control the Parkinson's yet.

A nutritional supplement called inosine converts to urate once it's ingested, but further study is necessary to determine whether the supplement could be helpful for Parkinson's patients.
