ChromaDex Shares Findings from First-Ever Peer-Reviewed Published Clinical Study Analyzing the Promising Effect of Nicotinamide Riboside (NR) Supplementation in Patients with Parkinson’s Disease (PD)
New Phase I research showcases NR supplementation significantly increased cerebral NAD levels, and decreased levels of inflammatory cytokines in Parkinson’s disease (PD) patients
Parkinson’s disease is a common neurodegenerative disorder, affecting more than 10 million people worldwide. It is largely characterized by progressive impairments in motor function, including tremor, stiffness, slow movement, and poor balance, as well as in non-motor functions, such as abnormal sleep patterns, gastrointestinal dysfunction, and cognitive impairment, or dementia. Abnormal energy metabolism due to dysfunction in the mitochondria, the powerhouses of the cell, has been linked to PD and is believed to play a role in the initiation and progression of the disease. As such, this study assessed NR as a potential therapeutic strategy targeting mitochondrial function and energy metabolism in PD patients.
“The results of this phase I study in humans are an encouraging step forward for Parkinson’s research and a potentially promising alternative for PD therapy,” said Dr.
“We are very excited about these results,” said Prof. Charalampos Tzoulis, Professor of Neurology and Neurogenetics, Director of the K.G Jebsen Center for
This randomized, double-blinded, placebo-controlled human phase I clinical study featured 30 newly diagnosed patients with PD who never received dopamine therapy (a standard treatment used to treat motor symptoms in PD patients). The patients were randomized into two groups - one group was provided 1000mg/day of NR and the other a placebo. Clinical, neuroimaging and molecular measures were used to assess all patients at baseline and after 30 days of exposure.
The results of the study demonstrated that NR-recipient patients showed significantly increased brain NAD levels, an altered brain metabolic pattern, and decreased levels of inflammatory cytokines in the cerebrospinal fluid. Moreover, patients experienced a mild but significant clinical improvement, and this correlated with the change in the brain’s metabolic pattern.
“These findings, particularly the effects on pro-inflammatory cytokines and clinical symptoms, are clearly supportive of carrying out larger trials in Parkinson disease patients," said Dr.
These promising results suggest that NR supplementation may have neuroprotective potential by targeting various processes implicated in the development of PD, however further research needs to be conducted on its use as a potential therapeutic strategy.
