@drhalland: "Many people believe they can’t eat as much as they used to because their metabolism slows down—a common part of aging. The real reason? Declining NAD levels. NAD is a key molecule that fuels your metabolism, and as its levels drop with age, so does your body’s ability to efficiently burn calories. But here’s the good news: by supplementing with NAD, you can boost your cellular function and metabolism, giving your body the support it needs to maintain a healthy weight and energy levels. It’s not just about aging gracefully—it’s about optimizing your body from the inside out."
