NAD+ And Parkinson's Disease

Energy Production: NAD+ is a key player in the mitochondria, the energy-producing powerhouses of cells. Mitochondrial dysfunction is a known feature of Parkinson’s disease, and enhancing mitochondrial function through NAD+ supplementation may help improve energy production and overall cellular health in affected neurons. 

Neuroprotection: NAD+ has shown potential neuroprotective effects in preclinical studies. It may help protect dopaminergic neurons (the cells primarily affected in PD) from oxidative stress, inflammation, and other factors that contribute to their degeneration. This protection could slow down the progression of PD. 

DNA Repair: DNA damage is thought to be involved in the development of Parkinson’s disease. NAD+ is essential for DNA repair enzymes known as PARPs (poly ADP-ribose polymerases). By supporting DNA repair mechanisms, NAD+ may help maintain the integrity of neurons and reduce the accumulation of DNA damage. 

Sirtuin Activation: NAD+ is a coenzyme for sirtuins, a family of proteins involved in regulating various cellular processes, including inflammation and oxidative stress. Sirtuins are involved in maintaining the health of genetic material. Activating sirtuins through NAD+ may have anti-inflammatory and antioxidative effects, which could benefit individuals with PD. 

Enhanced Autophagy: Autophagy is a cellular process that helps remove damaged or dysfunctional components, including misfolded proteins like alpha-synuclein (associated with PD). NAD+ may support autophagy, which could aid in the clearance of toxic protein aggregates seen in PD. 

Improved Mitophagy: Mitophagy is a specific form of autophagy responsible for eliminating damaged mitochondria. Dysfunctional mitochondria are implicated in PD. NAD+ may help enhance mitophagy, leading to the removal of damaged mitochondria and the promotion of healthy ones. 

Neurotransmitter Regulation: NAD+ is involved in the regulation of neurotransmitters, including dopamine, which is depleted in PD. Maintaining balanced neurotransmitter levels may help alleviate some motor and non-motor symptoms of the disease. 

Anti-Inflammatory Effects: Chronic inflammation is associated with neurodegenerative conditions like Parkinson’s disease. NAD+ may have anti-inflammatory properties that can help reduce inflammation in the brain, potentially slowing disease progression. 

NAD+ therapy and its use in Parkinson’s disease were areas of active research but not yet widely adopted in clinical practice. Therefore, it’s crucial for individuals with PD to consult with their healthcare providers to explore appropriate treatment options and potential integrative approaches based on the latest medical advancements and research findings.
