Dr. Jin-Xiong: Founder of Jinfiniti

Episode 88: NAD, Longevity Biomarkers, and the Future of Personalized Health (Part 2)




🎧 Episode Overview


In this episode of the BiohackerBlondie Podcast, Jenny Jones welcomes back Prof. Jin She, PhD, founder of Jinfiniti and a global leader in NAD research, longevity biomarkers, and precision health testing.


This is Part 2 of their conversation, where they move beyond the basics of NAD and dive deeper into what truly drives long-term health: personalized testing, actionable biomarkers, and proactive optimization.


Prof. Jin She shares how his background in molecular genetics, population genetics, and data science has shaped his mission to make longevity measurable, accessible, and precise. Together, Jenny and Prof. Jin She explore why guessing your health strategy is no longer enough—and how targeted testing can dramatically improve outcomes, reduce unnecessary supplementation, and prevent long-term disease.


They also discuss Jinfiniti’s expansive 47-biomarker longevity panel, how global population data reveals important health patterns, the real dangers of supplement overload, and why oxidative stress is far more widespread than most people realize.

If you want to understand what your body actually needs—rather than relying on trends—this episode is essential listening.


👨‍🔬 About Prof. Jin She, PhD


Prof. Jin She is a molecular and population geneticist, former medical school professor, and the founder of Jinfiniti. His work bridges biology, artificial intelligence, and data science to create advanced biomarker testing tools that help people understand and optimize their health with precision.


With decades of academic experience and global population-level health data, Prof. Jin She has built some of the most comprehensive longevity testing panels available today—including the only widely available NAD testing platform. His mission is simple: help people live longer, healthier lives through measurable, personalized health insights.


🧠 What You’ll Learn in This Episode


• Why personalized biomarker testing is the foundation of longevity• How NAD impacts aging, energy, DNA repair, and cellular health•


What makes Jinfiniti’s 47-biomarker longevity panel so unique• The “T.A.O.” framework: Test, Act, Optimize• Why most people are taking supplements blindly—and why that’s dangerous• How supplement overload can damage kidney and liver function• Why oxidative stress is extremely high in modern populations• How toxins, heavy metals, and microplastics impact aging• The hidden risks of nutrient deficiencies—even in “healthy” diets• Why proactive testing is more powerful than reactive medicine• How population-level data reveals major health trends• The connection between physical health and mental well-being


🔍 Why Testing Comes Before Supplements


One of the most important themes of this episode is that testing must come before intervention.


Many people take dozens—sometimes hundreds—of supplements without knowing:

• What they actually need

• What is working

• What may be harming them


Prof. Jin She explains that without testing, most people are essentially guessing. This can lead to nutrient imbalances, metabolic strain, and even organ dysfunction over time.

Jenny emphasizes that testing is one of the most powerful investments you can make in your health—not a luxury. Knowing your NAD levels, inflammatory markers, hormone balance, oxidative stress, and micronutrient status allows you to personalize your health strategy instead of copying someone else’s routine.


🔁 The T.A.O. Framework: Test, Act, Optimize


Prof. Jin She introduces a powerful longevity framework inspired by Taoist philosophy:

T – Test:You must measure what is happening in your body before taking action.

A – Act:Once you know your data, you implement targeted interventions—diet, supplements, lifestyle, and therapies.

O – Optimize:You retest and refine. Longevity is not a one-time fix—it’s an ongoing process.

This cycle allows people to avoid guesswork and continuously improve their health with real data.


⚡ NAD: The Master Molecule of Longevity


NAD (nicotinamide adenine dinucleotide) plays a central role in:

• Cellular energy production

• DNA repair• Mitochondrial health

• Inflammation regulation

• Neuroprotection


As we age, NAD levels decline, which accelerates aging and disease risk.

What makes Prof. Jin She’s work unique is that he doesn’t just offer NAD supplementation—he provides actual NAD testing, allowing people to:

• See their baseline levels

• Track progress

• Personalize dosing

• Avoid unnecessary supplementation


This is a major leap forward in precision longevity.


🧬 Inside the 47-Biomarker Longevity Panel


Jinfiniti’s longevity panel includes 47 core biomarkers—and continues expanding. These include markers related to:

• Cellular aging

• Inflammation

• Immune function

• Metabolic health

•Hormones

• Growth factors

• Mitochondrial function

• Cognitive decline risk

• Oxidative stress

• Nutrient deficiencies


Prof. Jin She explains that no single marker tells the full story—longevity is a systems-based equation. The power is in seeing how all systems interact.


⚠️ The Hidden Danger of Supplement Overload


A major insight from this episode is how common supplement-related damage has become.

Many biohackers unintentionally overload:

• Kidneys• Liver• Detox pathways

This can lead to long-term damage, fatigue, inflammation, and even increased disease risk.

Jenny and Prof. Jin She both emphasize that supplements are tools—not solutions. Without lifestyle changes, proper nutrition, sleep, and stress management, supplements alone cannot fix underlying dysfunction.


🔥 Oxidative Stress: The Silent Driver of Aging


Oxidative stress is one of the most powerful accelerators of aging and disease.

Prof. Jin She explains that:

• A large percentage of Americans have extremely high oxidative stress

• Environmental toxins, heavy metals, and microplastics are major contributors

• Even “healthy” diets can still result in deficiencies and oxidative burden


This is why individualized testing is so critical—two people can eat similar diets but have drastically different biological responses.


🌍 Why Global Data Matters


One of Prof. Jin She’s unique strengths is his access to global population-level data.

By analyzing patterns across countries, cultures, and diets, he can identify:

• Nutrient deficiency trends• Metabolic vulnerabilities• Disease predispositions• Environmental impacts

This allows for smarter testing panels and more accurate predictions about long-term health outcomes.


💛 Longevity Is About Feeling Good—Not Just Living Longer


Jenny shares a powerful reminder: longevity isn’t just about lifespan—it’s about healthspan.

When your physical health improves, your mental health often follows. Energy increases. Pain decreases. Mood improves. Focus returns.

Longevity isn’t about living longer in a fragile body—it’s about thriving.

✨ Final Thoughts


This episode makes one thing clear: longevity is no longer guesswork.

With the right data, the right biomarkers, and the right strategy, you can take control of your health before disease ever shows up. NAD, oxidative stress, hormones, inflammation, and nutrient status are not abstract concepts—they are measurable, actionable, and modifiable.

If you want to feel better, think clearer, age slower, and live longer, testing is the first step.Episode Overview
