A Note From Our Founder
Why I Stopped Recommending Supplements and Started Formulating My Own
For a decade I wrote the same complex recommendations for tired patients, piecing together supplements from a dozen different brands. Here is why I finally decided to build the formulas myself.

A Decade of Writing the Same Prescription
As a functional medicine practitioner, I spend the majority of my days looking at comprehensive lab work. Over the past decade, I have consulted with thousands of patients from all over the world. They arrive tired, frustrated, and overwhelmed.
For years, my job involved writing down the same complex recommendations over and over. I would tell someone to buy a specific fermented B vitamin from one brand, a highly bioavailable magnesium from another, and a specific antioxidant blend from a third company. I had to do this because no single brand met my standards.
The Problem Became Impossible to Ignore
The problem became obvious quickly. My patients were spending hundreds of dollars every month. They were taking twenty different capsules a day just to hit their baseline nutritional needs. And many of the products on the market were built around cheap binders, synthetic ingredients, or forms of vitamins the body struggles to absorb.
I was trying to build a modern approach to cellular health using outdated tools.
“That is the moment I stopped recommending a patchwork of different brands and decided to build LongevityRx.”
So I Built the Formulas Myself
I wanted to create the exact formulas I was trying to piece together. I refused to compromise on ingredient quality. I refused to use standard, ineffective dosages just because they were cheaper to manufacture. Every product in the LongevityRx line was built from a place of real need.
Let me walk you through each product and tell you why it exists.
Liv120: The Full Color Spectrum, In One Scoop
Here is something most people never hear: the color of a plant is information. Each pigment family, the reds, the purples, the blues, the greens, carries a different set of phytonutrients that supports a different part of how your cells make and use energy. Most people eat two or three colors on a good week. Almost nobody eats all of them.
That is the gap I built Liv120 to close.
Our team searched the globe to build what I believe is the first cellular superfood carrying the full spectrum of health-promoting colors: red ginseng, black currant, purple acai, blue turmeric, green matcha, orange reishi, yellow astragalus, and white soursop. Thirty longevity superfoods in total, formulated to support your body’s longevity pathways and mitochondrial function.
The fermentation is not a marketing detail. It is the reason the formula works the way it does. Fermenting the inputs, the blue turmeric, the red mulberry, makes the nutrients more bioavailable. Your body does not have to work as hard to break them down or convert them into a usable state. They go to work at the cellular level.
I built the base around organic pomegranate, which supports healthy circulation and vitality. Then soursop and noni, both of which support immune function and healthy energy levels. Then the rest of the spectrum on top.
Liv120 is where I tell people to start. Not because it does everything, but because energy at the cellular level is what everything else is built on top of.

Mag18: Peptide-Powered Minerals
Magnesium is involved in hundreds of enzymatic processes. It supports your nervous system, your bone health, your metabolic function, and restful sleep. It is also one of the most common shortfalls I see, and not because people are not supplementing it. It is because most magnesium does not absorb well.
Magnesium oxide, the form used in most products on the shelf, has a poor absorption rate. Most of it passes through without ever reaching the tissues that need it.
When I formulated Mag18, delivery was the whole problem to solve. We built it on whole food magnesium chelate and paired it with 18 amino acid peptides from hydrolyzed spirulina, what we call Peptide-Powered Minerals™. That peptide pairing is the difference. It is what supports the magnesium actually being absorbed and used, rather than passing through.
Then we added vitamins D3 and K2, because magnesium does not work alone. D3 supports calcium absorption. K2 helps direct that calcium toward your bones. Magnesium supports the bone structure itself. Together they support strong bones and healthy cardiovascular function in a way none of the three does on its own. Organic spirulina and beet root round out the formula.
When your cells have what they need, your nervous system can settle. Sleep gets deeper. Muscle tension eases. That is the version of magnesium I always wanted to hand my patients.

Probiotic Trillion: One Trillion, Four Ways
The gut communicates with nearly every system in your body. It talks to your brain through the vagus nerve. It supports your immune response and your hormonal balance. When the gut is out of balance, you feel it everywhere else.
I was tired of recommending probiotics that did not survive the trip. Many fragile strains struggle in the acidic environment of the stomach. You are paying for bacteria that may not arrive.
Probiotic Trillion is a trillion CFU, four-in-one formula: probiotics, prebiotics, parabiotics, and postbiotics. It is built on Bacillus subtilis AB22, a spore-forming strain selected specifically because it survives the journey, paired with humic soil extract. The prebiotics feed the beneficial bacteria once they arrive. The parabiotics and postbiotics support the gut lining and a balanced immune response. Advanced detoxification support is built in.
In Gut Feelings I wrote about shameflammation, the way unresolved stress patterns keep the nervous system in a state that the gut ends up carrying. Supporting the gut physically, with strains that arrive and nutrients that feed them, is one of the most useful places to start. Probiotic Trillion is the tool I reach for.

StemCell Protein: More Than Amino Acids
Collagen earned its popularity. There is real science behind its role in skin, joints, and bone. But standard collagen gives your body an amino acid profile and not much else.
StemCell Protein goes further. We formulated it with grass-fed beef protein, chicken bone broth, bone marrow, including bio-identical lipids, and organ peptides from heart, liver, and kidney, delivering naturally occurring peptides and nucleic acids. This combination mirrors the nutrient profile humans ate for most of our history, nose to tail.
We also included Bacillus subtilis AB22, a probiotic strain chosen specifically to support protein and fat digestion, because a protein you cannot absorb is not doing anything for you.
For anyone over 45 noticing joint discomfort and changes in skin and bone, StemCell Protein supports the structural side of healthy aging in a way standard collagen does not.

Two More Formulas Worth Knowing
Each of these deserves its own article. MitoMultiply uses methylated, active forms of B vitamins, B6, folate, and B12, so your body does not have to do the conversion work. Cellular Hydration pairs electrolytes from Celtic Sea Salt, organic watermelon, and coconut water with a balanced potassium-to-sodium ratio. I take it every morning, before food, before coffee.
MitoMultiply
A methylated multivitamin with B6, Folate, and B12 for energy production, metabolic function, and mental clarity.
Cellular Hydration
Wild berry electrolyte stick packs with premium ingredients for deep cellular hydration and balance.
The Bigger Picture
When you take a LongevityRx product, you are not taking another supplement off the shelf. You are taking a formula refined over a decade of patient care. Every product in this line exists because I saw the same gap show up again and again in what my patients were using, and I decided to build something better.
If you want to understand the science behind any of these formulas, the research is transparent and available. I built this line to be something I could stand behind completely, and I do.
