Nicotinamide Riboside Supplementation Does Not Disrupt Methylation, Including in Individuals with MTHFR Mutations: Clinical Findings
Objectives
To investigate the impact of NR supplementation on DNA methylation patterns in the blood cells and muscle tissues of newly diagnosed, dopaminergic treatment-naïve Parkinson's disease (PD) patients.
Journal
iScience
Key Outcomes
- NR supplementation had no impact on DNA methylation in PD patients, including in those with common mutations in the MTHFR gene.
- NR also resulted in minor changes in the activity of metabolic pathways and patterns of DNA methylation. However, these changes were not harmful and did not disrupt normal DNA methylation.
