The Skinny Confidential Him & Her Show: "The Future of Health: Why Proactive Care Starts With Your Data"

Featuring Nate Graville (Founder of Jeviti)
Date: December 19, 2025

Episode Overview

In this episode, Lauryn and Michael Bosstick sit down with Nate Graville, founder of Jeviti, a cutting-edge health technology company focused on personalized blood work and proactive longevity care. The trio discusses why individualized health starts with your data, how new technology can turn blood panels into actionable life-enhancing advice, and why a proactive (rather than reactive) approach to health is overdue. Nate shares his personal story that motivated Jeviti’s founding, debates popular health trends, and demystifies what people can expect from modern health testing platforms.

Key Discussion Points & Insights

1. The Emotional Case For Proactive Health

• Nate’s Motivation: Nate shares he was driven to create Jeviti after his father's unexpected death from undiagnosed cancer. His father, like many, avoided blood draws due to needle phobia—highlighting how reactive medicine too often comes too late.
  • “It's a misconception that us feeling fine means that we are fine.” — Nate (03:43)
• Importance of Blood Work: Blood work is described as the health “blueprint” — a tool to detect potential issues before symptoms manifest, helping identify risks of chronic disease or deficiencies early on.
  • “There’s just no way to actually know what's happening underneath the hood unless you get your blood drawn.” — Nate (03:06)

2. Overcoming Fear & Misconceptions

• Lauryn candidly expresses her anxiety around blood and needles, paralleling a common obstacle: fear. Nate encourages twice-yearly draws being sufficient if comprehensive panels are run, with modern labs reducing both frequency and blood volume required.
  • “I would rather give birth 20 times than get my blood taken.” — Lauryn (01:42)
• Needle phobia is validated as real and widespread, but outweighed by the benefits of uncovering hidden health issues early.

3. Personalization Beats Guesswork

• Most people supplement based on trends—not individual needs. Blood work tailors supplementation, lifestyle, and nutrition to the actual deficiencies, reducing unnecessary (sometimes harmful) over-supplementation.
  • “You can't fly blind with supplementation...We find a lot of people come to us and...they don't need any of this.” — Nate (09:07)
  • Example: Overusing vitamin D can be toxic if unneeded.

4. Limitations of Current Healthcare & The Need for a Paradigm Shift

• The hosts and Nate critique the US’s reactive “sick care” system, with enormous GDP investment producing declining public health.
  • “In 1970, 7% of our GDP was spent on healthcare...today it's 20%...the more we spend, the more unhealthy people actually get. That is nonsense.” — Nate (20:36)
• They agree that system incentives and accessibility (food deserts, cost of healthy food vs. junk food, SNAP restrictions) stack the deck against average people wanting to be healthy.

5. Hot Takes & Debunked Narratives

• The Medical Medium’s Viral Claim: The suggestion that frequent hospital blood draws strip patients’ immune systems is dismissed as baseless, with Nate emphasizing blood and gut serve different functions.
  • “To say your immune system lives in your blood is interesting. I'd argue your immune system lives in your gut, not in your blood...it's nonsensical.” — Nate (14:29)
• Fertility and Modern Lifestyles: Declining fertility rates are explored, with Nate highlighting hormone imbalances in both men and women and suggesting lifestyle and over-prescribed birth control are partly to blame.
  • “Fertility is a big issue. We're seeing men with incredibly low testosterone...for women, it probably has a lot to do with birth control and just how over prescribed birth control is.” — Nate (17:25)

6. Brian Johnson, Biohacking, and The Limits of Longevity

• The group debates the purpose and philosophy of biohacking. While respect is shown to data-driven approaches, Nate calls chasing immortality a vain pursuit, sharing his Christian perspective on life’s purpose.
  • “Trying to achieve physical perfection is like a vain pursuit...Let's maximize our years so I can watch my children grow…and be around for generations—not just to maximize our years.” — Nate (26:02)
  • “If you're going to biohack your way through life, I would hope you’re biohacking with a destination, with a goal in mind. Not just ‘let’s live forever.’” — Nate (29:56)

7. Modern Wellness, Social Trends & Young Men

• The hosts and Nate discuss Gen Z’s declining alcohol consumption, its impact on socialization, dating, and fertility—contrasted with negatives like increased screen time and easy access to pornography.
  • “Who needs intimacy with a real human when I can watch porn? That's the problem that young people are having.” — Nate (35:43)
  • The effects of frequent porn use on hormone levels, ambition, and societal health are also discussed frankly.

8. Jeviti’s Approach & Practical Questions

• How It Works: Jeviti brings health panels to your door, offering comprehensive biomarker testing—roughly eight vials per session, with improvements in process compared to legacy labs.
  • “It’s one poke. After the poke is done, the vials of blood don’t matter...compared to giving blood, donating blood…we’re talking a tenth of that.” — Nate (11:03)
• Personalized Supplement Packs: Instead of self-managing multiple bottles, Jeviti packages tailored AM/PM packs using pharmaceutical-grade supplements, adjusting contents as new data comes in.
  • “My pack is not going to look anything like Eli's pack out there because our blood work looks different.” — Nate (42:05)
• Beyond Blood Work: Additional offerings include GI maps (stool sampling for gut analysis), toxicity panels, heavy metal and mold exposure testing, and methylation assessments for drug sensitivity and psychiatric side effects.

9. Data Privacy in the Age of Health AI

• The hosts raise concerns about health data privacy and potential misuse. Nate acknowledges both the necessity and public anxiety, asserting Jeviti’s policy that users own their data (not to be sold) and transparency is key.
  • “You own your data. It's not ours. We promise to never sell it...If you ask us to delete it…we're going to wipe it from the system.” — Nate (48:03)
• Future plans include open source verification so users can confirm data deletion and privacy policies themselves.

10. The Promise of AI in Personalized Medicine

• With individualized blood and lifestyle data, Jeviti aims to use artificial intelligence to create highly accurate, dynamic risk profiles for each customer—enabling continuous, preventive care.
  • “We think that we will have the most predictive mortality calculators in the world with 95 to 98% certainty...five, ten years out.” — Nate (54:33)
  • The goal is reducing risk through ongoing, meaningful lifestyle adjustments, not overwhelming overhauls.

Notable Quotes & Memorable Moments

• On Ignorance vs. Proactivity:
  “In some instances, I would argue ignorance is bliss. This is not one of them.” — Nate (06:15)

• On Supplement Trends:
  “What we do specifically is based on having some accurate information...It’s a good idea to know what you need, what you don’t need.” — Michael (08:43)

• On Nutrition Inequality:
  “People are met with a decision: do I feed my family of five with ultra processed foods…or feed half with whole foods?...That’s a terrible position.” — Nate (23:56)

• On the Futility of Chasing Immortality:
  “To live forever in this world, to me, seems like we’re trying to basically achieve eternity in hell in a sense.” — Nate (26:02)

• On Blood Draws for the Needle-Phobic:
  “If they can get elderly people or children in one single poke…there will be no issues. You won’t even feel it.” — Nate (59:19)

• On Data and Trust:
  “It’d be a little ignorant to think that...they don’t already have the data, right?” — Nate (47:31)

• On Jumpstarting Longevity:
  “You need a catalyst. And we don’t think that catalyst is a drug. We think that begins with a paradigm shift: preventative before reactive, proactive before reactive, paired with artificial intelligence.” — Nate (52:38)
