Nicotinamide is a key component of increasing cell survival and longevity, and plays a critical role in microglial function. It has been shown to prevent apoptosis in neuronal cells and is also a PARP-1 inhibitor, which has been shown to improve cognitive function in Alzheimer's disease patients (2).
