The NADPARK Study: A Randomized Phase I Trial of Nicotinamide Riboside Supplementation in Parkinson’s Disease
Objective
To assess the safety, tolerability, and cerebral penetration of NR therapy in Parkinson’s disease (PD) patients, as well as determine if NR has an impact on their neurometabolic profile and motor symptoms.
Study Design
Randomized, double-blind, placebo-controlled, phase I study in 30 PD patients
Dose
1000 mg
Duration
30 days
Key Outcomes
NR supplementation significantly increased cerebral NAD+ levels, altered brain metabolic pattern, and decreased levels of inflammatory cytokines in the cerebrospinal fluid of PD patients.
Moreover, patients experienced a mild but significant clinical improvement, and this correlated with the change in the brain’s metabolic pattern.
