The Longevity Letter
Longevity & Precision Health
Hi {{ subscriber.first_name | strip | default: "there" }},
It's still me, Dr. Hillary Lin, of Elevate X! The company is going through a rebrand/rename that is hopefully more effective than HBO Max formerly Max.
So for now (and perhaps going forth), this newsletter will stand alone as The Longevity Letter, which is nice mainly because it alliterates.
Small piece of news: We quietly announced our early access partnerships—quiet not just because we're going to change our name soon but also because we've had overwhelming demand and want to make sure we can launch successfully in the Fall with our earliest partners.
That being said, please still reach out at hello@elevatexhealth.com if you're interested in adding to your brand a virtual longevity clinic with plug-and-play lab testing, personalized plans, prescriptions, and licensed clinicians under your label, with no extra headcount or compliance hassle.
Now let's dive into recent movements in the space.
This $5 vitamin just outperformed most anti-aging startups
The VITAL trial just dropped some compelling evidence that daily vitamin D3 supplementation significantly slows telomere shortening in older adults. While we've known vitamin D is important for bone health, this study suggests it's literally helping protect the protective caps on our chromosomes that shrink as we age. It's like giving your cells tiny umbrellas against the aging storm.
Before you rush to megadose, remember that vitamin D is fat-soluble and can build up to toxic levels. (I had a patient in the cardiac ICU once who OD'd on vitamin D and calcium leading to heart block!) Test your current levels and, if they're < 30-50 ng/mL (the range depicting the lower bound of optimal), then start at a low dose like 1000-2000 IU daily, and go slowly upwards.
Interestingly, the same study showed no beneficial effect on telomeres with marine omega-3 fatty acids, a longevity supplement darling. That being said, it's still one of my personal favorites for all its other health benefits!
Can we clean aging out of our "dirty" blood?
Therapeutic plasma exchange (TPE) sounds like something from a sci-fi movie, but researchers actually did it to 42 people with an average age of 65. They essentially filtered out the "old stuff" from participants' blood plasma and found measurable improvements in biological age markers—2.6 years younger on average. The study showed reduced DNA damage, better immune balance, and even decreased Alzheimer's-related proteins.
The catch? TPE carries real risks and serious costs ($10,000 per session—and you'd need to keep doing it biweekly per this study's protocol) – this isn't exactly something you'll be doing at your local wellness center anytime soon. Still, it's a fascinating proof of concept that aging might be more reversible than we thought.
Longevity influencer Bryan Johnson is wealthy enough to experiment frequently with TPE and related therapies.
Stanford longevity expert's secret weapon against aging: touching grass (literally)
Dr. David Furman was 39 chronologically but testing at an inflammatory age of 42, dealing with chronic migraines and urban stress. His solution? Pack up the family, move to a forest cabin, eat organic food, use candlelight in the evenings, and do a digital detox. Three years later, his inflammatory age dropped to 32. Sometimes the most cutting-edge longevity intervention is just... living like our great-grandparents.
Plot twist: you don't need expensive biohacking gadgets to move the needle on biological age. Sometimes the biggest breakthrough is removing yourself from chronic stressors – even if it means trading your startup hustle for actual trees.

How to make millions: have "longevity" in your company name and put cancer tests in grocery stores
Longevity Health Holdings, a public company, just announced a merger with 20/20 BioLabs, completed a reverse stock split, and is launching multi-cancer tests in Giant Food stores. With Q1 sales showing solid growth and new product launches planned, the longevity sector is moving from experimental to commercial reality.
We're witnessing the longevity industry mature in real time – moving from theoretical research to actual products you can buy at your local grocery store. When cancer screening tests are available next to the bananas, you might wonder if *you* are going bananas.

Breaking: beauty industry discovers aging is bad for skin, pivots accordingly
Vantage Specialty Chemicals launched four new "longevity-focused" personal care ingredients, complete with 12 formulations that emphasize wellness through nutrition, movement, and purpose. Because apparently even your skincare routine needs to be optimized for lifespan now.
What's fascinating here isn't the products themselves, but what it signals: the line between cosmetics and longevity is completely blurring. When beauty companies start talking about mitochondrial health, you know longevity thinking has officially gone mainstream.
