Most people think low energy means they need more caffeine, more sleep, or more motivation. But what if the real issue starts much deeper, at the cellular level? In this episode of the Kwik Brain podcast, I sit down with Dr. Andrew Shao, nutritional biochemist and Senior Vice President of Global Regulatory and Scientific Affairs at Niagen Biosicence @niagenbio to explore what actually creates energy inside your cells and why maintaining that system becomes increasingly important as you age. We break down NAD+, a molecule involved in cellular energy production and repair, why NAD levels may decline in metabolically active tissues as we get older, and how lifestyle factors like poor sleep, smoking, excess alcohol, pollution, and poor nutrition can place additional stress on that system. Dr. Shao also shares how to separate promising science from clever marketing, what to look for when evaluating supplements, and why clinical research, quality testing, and third-party certification matter. In this episode, you will learn: ✅ What NAD+ is and why your cells need it ✅ Why energy is something your body creates, not simply something you “have” ✅ How NAD+ supports cellular energy production and repair ✅ What may happen to NAD levels as you age ✅ Which lifestyle stressors can increase demand on your cellular energy systems ✅ Why movement can actually help you create more energy ✅ The difference between NAD+ and NAD+ precursors ✅ What Dr. Shao says consumers should know about NAD IVs and supplements ✅ How to evaluate supplement claims using human research and third-party testing ✅ Why sleep, nutrition, movement, and stress management remain foundational ✅ What researchers are studying next in NAD+ and healthy aging After this episode, you’ll stop thinking about energy as something you have to chase and start understanding the daily habits and cellular processes that help your body produce, protect, and restore it.
