The People Behind the Formula
Dr. Robert Heller has practiced internal medicine for more than six decades. Over the course of his career, he managed fifty clinical trials, helped develop the Coronary Calcium Scan, and previously served as an Assistant Clinical Professor of Medicine at UCLA. He has seen thousands of patients navigate the experience of aging.
And he noticed a pattern he couldn't ignore. Two patients, same age, same general health profile. One was thriving: sharp, energetic, engaged. The other was struggling with fatigue, brain fog, and a body that didn't bounce back the way it used to. The difference wasn't willpower or attitude. Something deeper was at work.
He couldn't find a supplement that reflected this science: the right ingredients, in effective forms, at real doses. It didn't exist. Most products were marketing exercises. The few with promising ingredients buried them in hundred-compound formulas where effective doses were impossible to verify.
So he partnered with Dimitri Villard, MS, a Harvard-educated biotech entrepreneur who had co-founded research programs at the USC Keck School of Medicine, and together they built the formula Dr. Heller had been looking for his entire career.
“This is the formula I spent my career wishing existed. I take it myself, every day. Not because I have to. Because the research supports it.”

Precision Over Volume. Science Over Spectacle.
Thoughtfully Formulated
Juvelixir is made with carefully selected ingredients and a thoughtful approach to formulation.
We consider the available scientific literature, ingredient quality, and overall formula design as part of our development process, with a focus on creating products for everyday wellness.
Branded, Clinically Studied Forms Where It Matters Most
For several of our key ingredients, we chose branded forms from specialty suppliers who conduct their own published human clinical research on their specific compounds. This means you're getting the studied form that was tested, not a generic equivalent that may behave differently in the body.
For ingredients where branded forms don't materially affect bioavailability or efficacy, we source from vetted, quality-controlled suppliers and verify every batch through independent testing.
Total Transparency
Every batch of Juvelixir is independently tested to verify that every ingredient listed on the label is actually in the bottle, in the exact amounts shown.
No proprietary blends. No hidden formulas.
“We're not trying to be the supplement with the longest ingredient list. We're focused on rigorous formulation and quality you can trust.”
