The TAO of NAD: Why Your Cells Are the Secret to Longevity

By Dr. Jin-Xiong She

The journey seems impossible when I look back on my life, from a poor boy in rural China to a molecular biologist in the U.S.. And yet, here we are—talking about how to live longer, healthier, more vibrant lives.

If there’s one thing I’ve learned over four decades of research, it’s this: health starts at the cellular level.

You might think of your body like a well-built house. Your organs are the rooms. Your circulatory, immune, and digestive systems are the plumbing and wiring. But the real foundation? That’s your cells. And what fuels your cells, what keeps them clean, efficient, and full of life, is called NAD.

Maybe you’ve heard of NAD. Or perhaps it sounds like another buzzword. But this molecule, present in every cell of your body, is anything but trendy. It’s essential. Without it, your cells can’t produce energy, repair damage, or communicate properly. Without it, you age faster, often without realizing it.

So why haven’t most people heard about NAD until recently?

That’s a good question. The science has been around for over a century, but the tools to measure and optimize NAD have only recently caught up. We’re beginning a significant shift, where personalized health, data-driven insights, and smarter supplementation will dramatically improve how we age.

That’s why I founded Jinfiniti.

After years spent in labs researching genetics, diabetes, and organ transplant matching, I started to ask a bigger question: What if we stopped waiting for disease and instead focused on preventing it? What if we could optimize health before symptoms ever appear?

That question led me deeper into cellular health—and ultimately to NAD.

I want to be clear: NAD is not a magic pill. It’s a molecule your body naturally produces. But as we age, NAD levels decline, sometimes by more than 50% by our 50s or 60s. When that happens, our cells become less efficient. That leads to inflammation, fatigue, poor sleep, aches and pains, cognitive decline, and the diseases we associate with aging.

We’ve discovered at Jinfiniti that when people restore their NAD to youthful levels, the results can be profound.

I’ve experienced it personally. After decades of long work hours and chronic stress, my body began to feel older than my age. Joint pain, stiffness, fatigue—it all caught up to me. Tennis, my favorite form of exercise, became painful. Even sleep became less restful.

After just three months of optimizing my NAD, everything changed.

No more pain. No more stiffness. No more Tylenol before tennis. My sleep improved. My allergies vanished. And most surprising of all, even my mental clarity and mood lifted. I felt like myself again—actually, better than myself. I felt like the man I used to be.

But don’t just take my word for it.

We now offer the world’s first intracellular NAD test, developed by our team, including my brilliant wife, a PhD scientist who shares my passion for longevity. This test shows you how much NAD is actually inside your cells, where it matters most. From there, we help you build a customized plan to optimize your levels through supplements, lifestyle adjustments, and retesting.

That’s what we call precision health. It’s not about chasing symptoms. It’s about listening to what your cells are telling you—and taking action before problems arise.

We are building a bridge between ancient wisdom and modern science.

In Taoist philosophy, there is a saying: “That which is at peace is easily maintained.” That’s the essence of prevention. We want to catch the imbalance early, restore harmony, and let the body heal, renew, and thrive.

I’ve spent my life asking difficult questions, studying complex data, and developing new tools to understand human biology. But the lesson I’ve come away with is simple: when your cells are healthy, you are healthy. And when they are not, no surface-level treatments will bring you lasting vitality.

That’s why NAD is so powerful. It’s not about treating disease. It’s about optimizing life.

I invite you to learn more, test your NAD, and experience what’s possible when you nourish your body at the cellular level. I believe we all deserve to age with strength, clarity, and grace—not just to live long but to live well.

Let’s begin the journey together. After all, the Tao of NAD is not a quick fix. It’s a way of life.
