The Role of Supplements in Longevity and Healthy Aging
Longevity science is no longer about just living longer; it is about "health-span"—the number of years a person remains active and free of disease. Supplements in 2026 are a major part of this strategy, focusing on the health of individual cells.
A key player in this field is a molecule called NAD+. As people age, their natural levels of this molecule drop, which leads to lower energy and slower repair of DNA. Supplements known as "precursors" help the body rebuild its supply of NAD+. Other popular longevity supplements include Omega-3 fatty acids for heart and brain health, and collagen for maintaining the strength of skin, joints, and bones. The goal of these products is to provide the body with the "building blocks" it needs to repair itself, potentially slowing down the physical signs of aging from the inside out.
