Production of NAD+ declines sharply with age, leading to hidden cellular damage and visible symptoms like wrinkles, stubborn fat, cognitive fog, delayed recovery, and joint discomfort.[1][2][3] Emerging research suggests that this decline not only accelerates visible aging but also contributes to a cascade of metabolic and neurological issues, making NAD+ restoration a cornerstone of modern anti-aging protocols
