Measurable Results, Built Around You

Live Better.
Longer.

Your data-guided solutions for Chronic Fatigue

We’re living longer, but not always healthier. Jinfiniti helps you change that with three steps we call TAO: Test what’s going on in your cells, Act on what you find, and Optimize by testing again.

The TAO of Precision Longevity

Longevity isn’t one test or one bottle. It’s a loop: test, act, optimize.

Test. Know where you stand.Her first test was 18 µM. The goal is 40 to 100.

Act. Do what works for you.Other NAD+ products only got her to 21. Vitality↑ took her to 145, which was too high.

Optimize. Keep getting better.Retesting showed her dose could come down. Her last two tests were 55 and 68, right in the goal range.

Not every product works. If you don’t test, you don’t know.

Others sell tests. Others sell supplements. Jinfiniti closes the loop.

The TAO of Dr. Jin-Xiong She

  1. Early years · Rural China

    From Personal Loss to a Lifelong Mission

    Growing up where medical care was scarce, he lost his young sister to a preventable illness and saw serious illness strike his family. He vowed to master human biology so others wouldn’t face that same loss.

  2. 40 years · United States

    A Career at the Frontiers of Genomic Medicine

    He earned his PhD in Molecular Genetics and spent four decades in academia, becoming a global authority in personalized medicine.

  3. Today · Jinfiniti

    From Treating Disease to Preserving Vitality

    Modern medicine is excellent at treating disease. He saw a chance to find biological decline earlier, act with precision and measure what works. That idea became Jinfiniti.

The longevity problem

We’re Living Longer.
But Not Staying Healthy Longer.

Average lifespan is about 80, yet energy, focus and strength often start fading around 50. That leaves roughly 30 years lived below your best. This is the healthspan gap, and it’s the real longevity problem.

Illustrative; individual outcomes vary.

It isn’t fixed. By measuring what’s happening in your cells and acting early, you can extend your healthspan and live more of your years with energy, function and resilience.

How we close the gap: the 3 P’s
  • Proactive. Act early, while change is easiest
  • Personalized. Address the drivers of your health challenges, guided by your own data
  • Persistent. Preserve energy, function & resilience, year after year

Questions? We’ve Got Answers.

Where should I start?

Most people start with NAD+ Optimization® Essentials: test your NAD+, take Vitality↑, then retest. For the full picture of how you’re aging, choose the AgingSOS® Longevity Panel.

How much NAD+ should I take?

It depends on your starting level, which varies from person to person. That’s why we recommend testing first, then retesting to find what works for you.

What does the AgingSOS® panel measure?

Advanced longevity biomarkers that routine bloodwork usually misses, including intracellular NAD+, Klotho, cellular senescence, inflammation and oxidative stress.

Do I need to test before buying supplements?

No. Testing helps you personalize, but every supplement can be ordered on its own.

*In a Jinfiniti study of 26 adults aged 35 to 65 who took 2,000 mg of Vitality↑ daily, average intracellular NAD+ levels doubled after 4 weeks, measured with the Jinfiniti Intracellular NAD+ Test.
