Rooted in Research.
Designed for the Long Haul.
Your cells know how to renew themselves—they just need the right support. Our researchers discovered exactly what slows this natural process as you age. After years of testing, we created a formula that reactivates your body's own renewal system, helping your cells work like they did when you were younger.
We found validation where it matters most—at the cellular level
Our clinical trial showed measurable improvements in cellular health markers and real benefits for participants. We tested our formula in randomized, double-blinded placebo-controlled clinical trial because we care about creating products that actually work. These numbers represent real people experiencing real results from our formula.

32%
Our clinical trial demonstrated a significant 32% increase in key cellular renewal biomarkers (Beclin-1) over 6 months.

75%
75% of the treatment group reported positive effects, with those having more impaired cell health showing the greatest improvements.

16%
Participants experienced a 16% reduction in a CRP, a key inflammation biomarker

0%
Our formula produced no adverse side effects in extensive clinical testing.

Most supplements miss what your cells actually need as you age
Cellitas combines spermidine with spermine, two essential polyamines that work together in your body's natural cellular renewal system.
As you age, your body loses its ability to absorb these compounds from food. By including both spermine and spermidine, plus arginine (an amino acid that supports your body's polyamine pathway), we mirror how these compounds naturally work together in your body. This approach allows your cells to maximize the benefits of spermidine, the key driver of cellular cleanup.

The delivery system matters as much as the ingredients
What separates Cellitas from most supplements is our exclusive BB-12™ probiotic, backed by over 200 published studies. The BB-12™ probiotic has proven its health beneficial effect in numerous clinical studies focused on immune function and gastrointestinal health.
BB-12™ is a special probiotic that combined with arginine helps your microbiome produce additional spermidine ready to be absorbed in the gut and delivered to the cells of all your organs and tissues.

Your cells already know what they need. We help them get it.
Cellitas delivers full 8mg of spermidine, which has proven effective in our clinical study. Not all supplements provide this effective dose; doses below 4mg/day have not delivered any tangible health benefits. We combine it with spermine, arginine, the BB-12™ probiotic and MCT powder. Together, these ingredients activate your body's natural renewal process.

"Genetics only account for 30% of lifespan and disease avoidance. Our passions—nutrition, exercise, sunlight—play far greater roles."

What exactly is in Cellitas and how does each component work?
● Spermidine (8mg): The primary autophagy trigger
● Spermine: Can be turned into spermidine if cells require it (via the polyamine pathway).
● Arginine: Precursor of putrescine that can be turned into spermidine or spermine if cells require it. Works synergistically with spermidine.
● BB-12™ Probiotic: Enhances the synthesis and absorption of spermidine and provides immune benefits
● MCT Powder: Provides a short term energy boost and protects the other compounds from stomach acid that could degrade or reduce their effectiveness
This formulation mirrors how your body naturally processes polyamines from food, making it more effective than single-ingredient approaches.
