Nicotinamide Insights

Nampt plays a crucial role in regulating health by recycling nicotinamide to NAD+, which is essential for sirtuin activity. A surprising finding reveals that nicotinamide may inhibit sirtuins, acting as a feedback regulator that could hinder their function. This discovery emerged from early experiments demonstrating that high levels of nicotinamide resulted in inactive sirtuins, reshaping our understanding of its impact on cellular processes.
