NAD+ injection is a vital cofactor that plays a crucial role in numerous metabolic processes, particularly in energy production through mitochondrial function. By promoting healthy brain function and slowing cognitive decline, it helps boost energy levels, enhances metabolism, and regenerates cells. NAD+ is essential for DNA repair and regulating gene expression. It also supports neuroprotection by helping to repair damaged DNA in neurons and promoting neuroprotective factors, making it a potential treatment for neurodegenerative diseases. Additionally, NAD+ may slow aging by enhancing mitochondrial health and reducing inflammation.
