LongevityWay Weekly
Hey Longevity freaks. Quick, evidence-first hits — minus the hype.
Today’s lead: the 100+ club leaves a fingerprint in blood proteins — and it’s not “one magic molecule,” it’s a pattern.

🧬 Swiss Centenarians Have “Youthful” Blood Protein Profiles
The Summary
A new Aging Cell paper from the SWISS100 project profiled blood proteins in centenarians and found a subset of 37 proteins where centenarians looked more like the 30–60 group than the 80–90 group.
Key Details
Groups compared: centenarians (100–105) vs 80–90 vs 30–60.
The study found 583 differentially expressed proteins across groups, and highlighted 37 “youth-signature” proteins.
Those 37 map to big buckets that matter for aging biology: metabolism, immune/inflammation balance, extracellular matrix (your “body cement”), programmed cell death, and neurotrophic signaling.
A press summary also flags signals linked to lower oxidative stress, ECM regulation, metabolism, and even pathways touching DPP-4 / GLP-1 biology (interesting given this week’s GLP-1 trial news below).
Big caveat
This is association, not proof of causation. Also, the 80–90 group were hospitalized geriatric patients in the analysis, which can exaggerate “difference vs centenarians” if illness burden is higher.
Practical takeaway
Don’t chase one protein. The real takeaway is that exceptional longevity looks like many systems staying calm and coordinated: metabolism steady, inflammation controlled, tissues maintained.
Why It Matters
This is exactly the kind of “map” that can point to future drug targets — not by guessing, but by seeing what biology looks like in humans who actually make it to 100+ in decent shape.
LATEST NEWS
💉 UTMB Launches “Moody Longevity Trial” Tirzepatide (Zepbound) vs Biological Aging
The Summary
UTMB just launched a recruiting study asking a spicy, mainstream question: can tirzepatide (Zepbound) shift biological aging measures — not just body weight?
Key Details
Who: adults 55–70, BMI criteria listed, and specific exclusions (e.g., insulin use).
Timeline: 24 weeks on tirzepatide + 12 weeks follow-up.
What they measure: DNA methylation clocks (biological age) plus physical function/activity, inflammatory + brain markers, and quality of life/mood.
Big caveat
Even if clocks improve, that doesn’t automatically mean “slower aging forever.” It means: a measurable shift happened — and then we ask if it maps to real-world outcomes.
Practical takeaway
If you’re GLP-1 curious: this is the kind of study you want to see — prospective, structured, measuring more than vibes. If you’re not in the US trial area, still worth watching because it will shape the next wave of “GLP-1 for longevity” claims.
Why It Matters
GLP-1 class drugs are already mainstream. This trial is basically the bridge from “weight loss meds” → “geroscience hypothesis test.”

💊 NOVOS Core Reports Vascular Benefits in a Human Placebo-Controlled Trial
The Summary
NOVOS says its multi-ingredient formula improved endothelial function (FMD), arterial stiffness (PWV), and systolic blood pressure vs placebo in adults 40+ over ~6 months — which is rare to see claimed for a commercial longevity supplement.
Key Details
Study type described as randomized, double-blind, placebo-controlled.
Reported effect sizes include ~+2.9 percentage points FMD, ~1.18 m/s PWV, and ~6.1 mmHg systolic BP difference vs placebo.
Trial is registered as NCT06145087.
Big caveat (the important one)
Right now, most detail is coming through company comms / PR and a company write-up. They state it’s entering peer review, but independent readers should treat this as promising + not fully adjudicated until the full manuscript is easy to scrutinize. Also: multi-ingredient blends make it hard to know what did what.
Practical takeaway
File this under: “watchlist”. If the final paper holds up, it’s a meaningful upgrade for the supplement space. If it doesn’t, it’s still a good example of the standard we should demand: placebo-controlled, real functional endpoints.
Why It Matters
Longevity supplements usually move proxy biomarkers (or nothing). Vascular function endpoints are harder to budge — which is why this is getting attention.
BIOHACKER GADGET COMPARISON
🩺 Home Blood Pressure Tracking (Boring… and insanely high ROI)
The Summary
If you only track one “adult health” metric at home, make it blood pressure. Not because it’s sexy — because it’s a quiet long-term damage signal when it drifts up.
Run it like a mini-study (7 days)
Measure morning + evening, seated, same arm.
Ignore day 1 nerves.
Average the rest → that’s your baseline.
Re-check monthly, or during big lifestyle changes.
Simple gadget comparison
Option | Best for | Notes |
|---|---|---|
Withings BPM Connect (cuff) | Easiest “set & forget” routine | Claims up to 6 months battery; auto-sync style experience. |
Somron Evolv (cuff, portable) | Travel + minimal setup | “All-in-one” cuff unit; many orgs recommend validated cuffs over estimates. |
Aktiia (cuffless wearable) | People who hate cuffs | Needs calibration and it’s not the same as a classic cuff; convenience trade-off. |
Samsung Galaxy Watch BP feature | “Nice-to-have” trend tracking | Requires calibration; availability varies by region/regulatory status. |
SUPPLEMENT OF THE WEEK
🍫 Cocoa Flavanols (Endothelial function’s “food-grade” helper)
The summary
Cocoa flavanols (not “chocolate candy”) have consistent evidence for small improvements in blood vessel function and modest blood-pressure effects in controlled trials and reviews.
Benefits:
Vascular function: measurable bumps in endothelial function (FMD) in meta-analyses.
Blood pressure: tends to be a small average reduction, bigger if baseline is higher.
Pick this:
✅ High-flavanol cocoa (unsweetened cocoa powder) or a standardized cocoa-flavanol extract
❌ Avoid “chocolate” that’s mostly sugar + fat (that’s dessert, not a supplement)
How to use (practical)
Think daily, boring, consistent for 4–8 weeks, then reassess BP / how you feel.
If you’re doing the BP baseline above, this fits perfectly: add cocoa → watch the averages.
Safety (when to avoid / be careful)
Watch caffeine sensitivity (some cocoa has it).
If you have complex medical issues or meds, treat supplements as “real inputs” and check with a clinician.
PERSON TO FOLLOW
👤 Prof. Steve Horvath — the epigenetic clock guy
If you want one person who can keep you sane while everyone starts selling “biological age” screenshots, Horvath is a strong follow. He’s deeply involved in the clock science and regularly comments on what clocks can — and can’t — tell you.
