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.

When I was nine years old, a teacher pointed to me in front of my class and called me “the boy with the broken brain.”

For years, I believed that label. Learning felt difficult, reading was exhausting, and remembering information seemed almost impossible. But that struggle eventually led me on a 30-year journey to understand how the brain learns, adapts, remembers, and performs at its best.

In this episode of the Kwik Brain podcast, I’m sharing some of the most important lessons I’ve learned along the way, so you don’t have to spend decades figuring them out for yourself.

We’ll explore why mindset shapes your ability to learn, how metacognition can help you understand your own thinking, and practical tools like memory palaces, spaced repetition, speed reading, and active recall. I’ll also show you why movement, nutrition, hydration, and sleep are essential parts of learning and cognitive performance.

In this episode, you will learn:

✅ Why your beliefs about your brain can influence how you perform

✅ How to shift from a fixed mindset to a growth mindset

✅ What metacognition is and why it matters for learning

✅ How to identify and replace limiting beliefs

✅ How to use a memory palace to remember important information

✅ Why spaced repetition strengthens long-term memory

✅ How speed reading can help you process information more efficiently

✅ Why active recall is more powerful than passive rereading

✅ How movement supports learning, memory, and creativity

✅ Why nutrition and hydration matter for cognitive performance

✅ How sleep helps consolidate memories and support brain health

✅ How small changes can compound into greater mental performance over time

After this episode, you’ll have a clearer understanding of how to train your brain, improve the way you learn, and build daily habits that support better memory, focus, and mental performance.
