A 90-Year-Old Doctor Who Wanted
a Supplement He Could Believe In
Dr. Robert Heller spent more than 60 years practicing internal medicine. He watched the science of aging evolve from theory into something measurable — the 12 Hallmarks of Aging, a framework that tells us precisely what goes wrong in our cells as we get older.
But he noticed something troubling: almost none of the supplements available to his patients actually reflected that science. Most were marketing exercises. The few with real ingredients buried them in 100-compound formulas where effective doses were impossible to verify.
So at the age of 88, Dr. Heller co-founded Live Longer, Inc. with Dimitri Villard — a Harvard-educated biotech investor who had spent his career bridging research and real-world application. Together, they set out to build the formula Dr. Heller wanted to prescribe.
"Juvelixir is the formula I wanted to recommend to my own patients for years. At 90, I take it myself every single day."

4 Physicians

60+ Years
Trials basis
Human clinical
Quality verified
3rd-Party Tested
Precision Over Volume.
Science Over Spectacle.
Human Trials Only
Every ingredient in Juvelixir is backed by human clinical trials — not animal studies, not in-vitro experiments. If the research was not done in people, it did not make the formula.
Effective Doses, Always
We use the same doses that produced results in the clinical trials we cite. No "pixie-dusting" — the practice of listing an ingredient at 1% of its effective amount just to put it on the label.
Radical Transparency
Every batch is independently third-party tested. We publish exactly what is in each capsule, at what dose, and why. No proprietary blends, no hidden formulas, no guesswork.
Eight Ingredients.
All 12 Hallmarks Addressed.
The 12 Hallmarks of Aging are the cellular and molecular processes that scientists have identified as root causes of how we age. Juvelixir was built from the ground up to address every single one of them.
01
L-Ergothioneine
5 mg · twice daily
A rare amino acid found in mushrooms, now recognized as a longevity vitamin. Protects mitochondrial DNA and reduces chronic cellular inflammation.
02
Pterostilbene
25 mg · twice daily
A stilbenoid from blueberries and grapes with superior bioavailability over resveratrol. Activates SIRT1 and AMPK longevity pathways, supporting epigenetic health.
03
Hyaluronic Acid
60 mg · twice daily
The body's natural moisture matrix declines sharply after 40. Oral HA at clinical doses supports joint lubrication, skin hydration, and cellular communication.
04
Quercetin
125 mg · twice daily
One of the most studied senolytic compounds — it selectively clears aged, dysfunctional "zombie" cells that accumulate with age and drive inflammation throughout the body.
05
R-Lipoic Acid
150 mg · twice daily
The biologically active form of alpha-lipoic acid, acting as a universal antioxidant in both water and fat environments. Regenerates vitamins C and E, and supports mitochondrial energy production.
06
Rhodiola Rosea
200 mg · twice daily
An adaptogenic root from the Siberian highlands, studied for its ability to buffer the hormonal stress response — directly addressing how chronic stress accelerates biological aging.
07
Magnesium
150 mg · twice daily
Required by over 300 enzymatic reactions. Supports DNA repair, protein synthesis, sleep quality, and cardiovascular health — all processes that degrade with age.
08
Black Pepper Extract
2.5 mg · twice daily
BioPerine standardized piperine extract dramatically increases the absorption of the other seven compounds — ensuring what is on the label is actually what reaches your cells.
Why 8 is Enough
"We did not add an ingredient until we could name the hallmark it addresses."
