Summary
A growing concern among many individuals is not just a lack of time but a significant deficit in energy, which affects their ability to engage in daily activities. Jim Quick, a brain coach, emphasizes that energy is crucial for motivation and productivity, highlighting that an exhausted mind struggles to perform tasks effectively. He introduces Dr. Andrew Xiao, an expert in nutritional supplements, to discuss the science behind energy production and the common misconceptions surrounding it.
Dr. Xiao addresses prevalent myths, such as the belief that caffeine provides a long-term energy solution. He explains that while caffeine can offer a temporary boost, it is not sustainable. Instead, he advocates for physical activity and proper nutrition as essential components for maintaining energy levels. A key focus of their discussion is on NAD+, a critical molecule that plays a vital role in converting food into energy. Dr. Xiao clarifies that NAD+ cannot be directly ingested as a supplement; rather, the body requires specific precursors, such as nicotinamide riboside, to produce it effectively.
As people age, NAD+ levels naturally decline, which can lead to decreased energy and overall function. Dr. Xiao suggests that maintaining NAD+ levels through lifestyle choices, including exercise and a balanced diet, as well as supplementation with NAD+ precursors, can help mitigate these effects. He emphasizes the importance of choosing high-quality supplements backed by clinical research and third-party certifications to ensure safety and efficacy. The conversation concludes with a call to action for listeners to prioritize their energy management, reinforcing that small, consistent changes can lead to significant improvements in overall vitality and well-being.

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 Bioscience, 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.
