A 602 mg botanical and amino-acid blend of five researched compounds built to support the body's own cellular renewal, glutathione production, and long-term immune resilience.

What's inside
Indian Kino Tree Extract (Pterocarpus marsupium) is a traditional Ayurvedic botanical with a long history of use in rasayana, the Ayurvedic category for rejuvenation.*
Pine Bark Extract delivers a proanthocyanidin antioxidant complex studied for vascular structure and function, healthy circulation, cardiovascular health, and free radical protection. It bolsters the body's antioxidant defenses against oxidative stress affecting cells, tissue, and DNA, and the same compound is studied for healthy eyes, skin, and joints.*
Astragalus Root Extract is an adaptogenic botanical with a long tradition in Chinese herbal practice as an energizing Qi tonic for energy and vitality. It is researched for immune modulation and healthy white blood cell production and activity, for healthy liver and cardiovascular function, and for cellular longevity.*
L-Theanine is an amino acid found in green tea that promotes relaxation while maintaining alertness, without drowsiness. It supports calm mental focus, healthy cognitive function, healthy mood, stress adaptation, sleep quality, and neuroprotection, and moderates the effect of caffeine on the central nervous system.*
N-Acetyl Cysteine (NAC) is a direct precursor to glutathione, the body's master antioxidant, and supplemental NAC raises tissue glutathione levels. It supports liver, kidney, and immune health, aids the clearance of heavy metals such as mercury and cadmium, and supports healthy respiratory function through its antioxidant action.*

How to use
Take one to two capsules twice daily, with or without food. Dr. Martin's recommendation is to take it consistently for 60 to 90 days before evaluating results. This is a formula built for the long game, not the quick pulse.*
Why we made it this way
The core insight behind the original 2011 formula was simple: aging is a cellular event before it is anything else. Glutathione production drops. Oxidative damage accumulates. Cellular repair and renewal slow down. StemCell-MX supports all three with a stack that has been tuned and re-tuned for fifteen years and still outsells anything else in the line. The name points to that renewal work. The formula itself is botanical and amino acid, and contains no stem cells. It is the formula Dr. Martin takes every day and the one he built his reputation on.*
Supports a balanced inflammatory response. The NAC and polyphenol core work together to support the body's normal inflammatory balance and protect cells from free radical damage.*
Made to be taken every day. Formulated for consistent long-term use, the way the reorder base has always taken it.*
Fifteen years of continuous use. Originally released July 2011. Number-one selling product in Dr. Martin's former line for over a decade.
Refined, not replaced. Current formula upgraded with the latest research on all five core ingredients.
Made in the USA. Manufactured in a GMP-certified facility with third-party ingredient testing.
Who reaches for it
People building a long-game daily protocol. Adults 40 and up who would rather support the whole system than chase one thing at a time. Long-time StemCell-MX users on their second, fifth, or fifteenth year of daily use. Anyone who wants the flagship of Dr. Martin's more-than-four-decades of formulation work.
Stack it with Circulate-MX for cardiovascular circulation support alongside StemCell-MX's cellular antioxidant work. The cellular and the circulatory, addressed together.*
Stack it with Comfort Maxum for proteolytic enzyme support for joint, sinus, and inflammatory comfort. The LF longevity triad.*
The story behind the formula, from Dr. Martin
"In July 2011, when I was still the owner of my former company, an amazing formulation was released to the public. It was the result of a collaboration between me and a very talented, now-deceased employee named Larry."
Larry was an on-again, off-again alcoholic. When he was on the wagon, his ability to scour the research to figure out which ingredients would produce a formula that worked was extraordinary. When he fell off the wagon, he would disappear for a week at a time. It was brutal to watch.
To help him stay on the wagon, I set up a commission agreement that would compensate him for his research based on the quantity of product sold, but only if he was employed and present full-time. Sadly, it did not work. Larry was eventually found dead in his apartment when we sent someone to check on him after he was MIA from work for a week.
Larry was involved in much of our new product development. His research into essential oils is behind the development of our NuCell GH3-Rejuv Crème. He is sorely missed. His talent for innately understanding how to formulate products that work is irreplaceable.
In July 2011, Larry and I released the original formula. That is fifteen years ago. When I sold my former company in 2019, the formula was still the number-one selling product. It has helped tens of thousands of people live better, and I am grateful every day that Larry's parting gift to this planet is still doing its work.
For a product to remain the number-one seller after more than a decade is rare in this industry. The only reason it happens is that the reorders match the new orders, and the only reason for that is that the product produces real, felt results and people don't want to be without it. Fifteen years in, I still take it daily.
StemCell-MX is the upgraded version of that original formula. A lot of research has come out since 2011, and you deserve a formula that reflects the latest of what we know about each of its five core ingredients. This upgraded product is only available from Longevity Formulas.
In honor of Larry.
The formula that started fifteen years ago, current with what we know today, made to take every morning.
