Grass-fed beef liver
The densest dietary source of B12, retinol, copper, and heme iron on earth.
The methylation, energy, and iron foundation.*It's not aging. It's the food your body's been quietly running without. Four grass-fed beef organs, freeze-dried into two capsules a day. Real food. Real nutrition.
Freeze-dried liver, heart, kidney, marrow. NZ grass-fed. No prep.
Two capsules with breakfast. That's the protocol. Most people feel the shift in 2-4 weeks.*
It wasn't supposed to feel like this in your 30s. Or 40s. Or whenever it started.
The morning starts foggy. The first coffee is medicinal. By 11am you're functional, by 2pm you're hunting for sugar, and by 8pm you're done. You used to have a second wind. Now you barely have a first one.
Everyone tells you it's aging. It's not aging. It's that the modern food supply doesn't carry the nutrients your great-grandparents lived on — and your body has been quietly running on fumes for years.
It wasn't aging. It was the food.
The energy you remember — waking up rested, focused all afternoon, present in the evening — that wasn't a function of being young. It was a function of being well-fed by real food. Liver. Heart. Kidney. Marrow. The dense parts of the animal that every traditional culture ate first.
Modern grocery stores don't stock them. Modern multivitamins try to fake them with synthetic isolates your body recognizes maybe 30% of. The result: a generation of tired, foggy, coffee-dependent adults convinced this is just what their 30s and 40s feel like.
It's not. And the fix is older than the problem.
No more 3pm crash. Steady energy through the afternoon — without another cup of coffee.*
Most multis use ferrous sulfate — non-heme iron with absorption rates as low as 2-10%. Your body was built for heme iron from real food. Real heme iron absorbs at 15-35%. That's not a small difference; that's where afternoon energy comes from.
The cheap synthetic B12 form your liver has to convert before it can use it. About 40% of adults have a genetic variant that makes them bad converters. They're "taking B12" and still deficient. Real food B12 from beef organs is already in the active form.
The mitochondrial energy molecule. Your cellular battery. Production declines steadily after age 30 and most multis don't include it at all. Beef heart is the densest dietary source on the planet.
The cheap form that mostly passes through you. Real magnesium glycinate (the form we use) is the difference between sleeping deeply and "almost" sleeping. Most multis save 10 cents and skip the form that actually works.
None of this is a controversial take. Any functional medicine practitioner will tell you the same thing. The supplement industry uses cheaper forms because they're cheaper to manufacture — not because they work. Your energy is paying the difference.
100% grass-fed, finished on grass. No hormones. No grain. Freeze-dried within hours of harvest to preserve every cofactor — the way nature packaged them.
Pennsylvania Farm Show · c. 2003
I grew up showing cattle in 4H in Pennsylvania. I knew where my food came from.
Then college, the standard American diet, and years of being a flatter, foggier version of myself — assuming that was just adulthood. It wasn't. It was the food.
Well-raised beef is the most nutrient-dense food on earth. The densest part — the part every traditional culture ate first — is the organs. Liver. Heart. Kidney. Bone marrow. Modern science calls them superfoods. My grandparents called them dinner.
NutraVantix is me putting them back. Four organs, freeze-dried into two capsules. 100% grass-fed New Zealand pasture. No fillers. No synthetics.

Four organs. Three minerals modern adults are usually low on. One absorption enhancer. Nothing else.
The densest dietary source of B12, retinol, copper, and heme iron on earth.
The methylation, energy, and iron foundation.*Richest natural source of CoQ10 — the cellular energy molecule your mitochondria run on.
Where afternoon energy actually comes from.*Loaded with selenium, B6, and DAO enzymes that support detox pathways.
Selenium drives thyroid. Thyroid drives metabolism.*The fats and cholesterol-adjacent lipids your hormones are literally synthesized from.
The raw material for testosterone, estrogen, cortisol.*The premium form. Calms the nervous system, deepens sleep, supports stress recovery.
The most underdosed mineral in modern adults.*The most bioavailable form. Required cofactor for immune output and hormone production.
Modern intake almost always lags requirement.*Clinically-studied piperine extract — multiplies absorption of fat-soluble nutrients.
Small input, real difference in uptake.*Individual results. Testimonials reflect individual experiences and may not reflect the typical purchaser's experience. Results vary.

"Took a daily multi for fifteen years and never felt anything. Two weeks on this and the afternoon fog lifted. The multi was placebo. This is the real thing."*

"Used to need three cups to function. Three weeks in I noticed I only made one in the morning and forgot the afternoon one. My husband noticed before I did — said I seemed less tired."*

"45, eating clean, lifting four times a week. Still flat. Still foggy until coffee. Three weeks on these and I wake up actually awake. That alone is worth the bottle."*
