I know about Vit D and B bits. But, does anyone know about Vit C and PD?

Based on the available research, the focus has primarily been on vitamin D and B12 deficiencies in relation to Parkinson's disease. Vitamin D deficiency in particular has been linked to both motor and non-motor symptoms of Parkinson's disease, including verbal fluency, memory, mood, and smell impairment.

Before starting any vitamin supplementation, it's important to consult with your healthcare provider who can properly assess your levels through blood testing and recommend appropriate dosages. This is crucial because excessive supplementation can lead to adverse effects. For vitamin D specifically, research shows that people with Parkinson's may have lower levels due to reduced outdoor activities and sun exposure. The connection between vitamin D and Parkinson's is particularly interesting because the area of the brain rich in dopamine-producing neurons (the substantia nigra) contains many vitamin D receptors.
