The Day I Made Longevity Personal

How a personal loss turned a world-class scientist into a relentless champion for your healthspan

By Dr. Jin-Xiong She

When I began my career, I believed the answers to life’s most important questions would be found in a lab. I spent decades immersed in genetic research, focused on decoding the complexities of human disease. 

My work was meticulous, clinical, and data-rich. Understanding disease at the molecular level would enable me to help millions live longer, healthier lives.

But science alone doesn’t make health personal. Loss does.

Years ago, someone close to me—someone I loved—began to decline. It wasn’t dramatic at first. Just minor signs: fatigue, forgetfulness, pain that didn’t go away. Like most people, they chalked it up to “getting older.” 

But I knew better. By the time we had answers, it was too late.

I had access to the world’s best labs. But we didn’t test early. We didn’t know what was silently shifting beneath the surface. That loss broke me open in a way no research study ever could.

It also changed the direction of my life.

Longevity Is Not About Adding Years to Life—It’s About Adding Life to Years

When I founded Jinfiniti, it wasn’t just another supplement company. It was a mission.

I wanted to empower people, especially those over 40, with what the health industry often overlooks: real, measurable insights into their biology. Your energy levels, aging rate, and cognitive decline start with what’s happening inside your cells. And we can measure it.

I wanted to make science useful in everyday life, for everyone. We started with NAD+. It’s the molecule that powers every cell in your body, and it declines with age. Without enough NAD+, your mitochondria falter, your DNA repair slows, and aging accelerates. 

By testing NAD+ levels and restoring them through evidence-based supplements, we observed dramatic improvements—more energy, better focus, and enhanced skin and sleep.

But it was just the beginning.

We Are Not Guessing—We Are Measuring

Today, we offer the most advanced biomarker testing, including Klotho, the “anti-aging protein,” and other markers of inflammation, stress, metabolic health, and immune function.

No two people age the same way. A 55-year-old may exhibit biomarkers associated with a 40-year-old or a 70-year-old. Age depends on lifestyle, genetics, and invisible stressors that build up over time. If we can measure it, we can manage it. And if we can manage it, we can reverse or slow it.

I’ve seen people regain energy they thought was gone forever, parents become more active with their children, and older adults reclaim independence, confidence, and vitality—not because they hoped a supplement would help, but because we had the data to guide them.

The Tao of Longevity

I was born in China and raised in the traditions of Taoist philosophy. Tao teaches us that nature is always in balance and continually adapts. Longevity is not about fighting nature. It’s about working in harmony with it.

That’s what Jinfiniti stands for. Harmony between science and spirit. Between biology and lifestyle. Between prevention and personal responsibility.

I still spend time in labs and publish papers. However, I now see myself more as a guide.

I’m here to help people navigate the confusing world of health advice, supplements, and aging. I want to make it simple: Test, Act, Optimize.

When you know your biomarkers, you stop guessing. You start living.

My Invitation to You

You don’t have to wait until something breaks to start paying attention.

You don’t have to fear aging.

You just need the correct data and the right plan. At Jinfiniti, we’re not promising immortality. We’re offering clarity. Precision. And hope backed by science.

If you’re ready to understand your body in a way you never have, we’re here to help.

Because longevity isn’t a destination, it’s a choice you can start making today.
