AMS-2434

Parkinson's disease is a neuromuscular disease that is relatively common in elderly that has many potentials symptoms, including a variety of physical features that together reduce quality of life. The Study Team have developed a nutritional supplement (AMS2434) based on essential amino acids that targets improving muscle health and brain neurotransmitter balance. This protocol will determine in individuals with PD the effect of AMS2434 on muscle protein synthesis, neurotransmitter production, and mood and cognition.
