Discover the surprising link between cold extremities, rising blood pressure, and sluggish circulation — and how a new breakthrough can help.
By Keith Harrison, Anti-Aging Expert - January 30th, 2025
You pile on extra socks. You crank up the thermostat. Yet your fingers and toes still feel like ice.
If that sounds familiar, it might be time to listen to what your body is really trying to tell you: cold hands and feet can be an early red flag for sluggish circulation—a hidden imbalance that can sap your energy, contribute to rising blood pressure, and leave you feeling worn down before the day even starts.
Low Energy & Brain Fog – Oxygen-starved cells can’t deliver the vitality you need to stay alert and active.
Uncomfortable Blood Pressure – Narrow, stiff arteries often force your heart to work harder to pump blood.
Chilly Extremities – If warm blood can’t reach your hands and feet, you’re left shivering—even when everyone else is toasty.
Doctors often shrug it off as “just getting older.”
But millions of adults over 50 are discovering a natural way to tackle the root cause of compromised blood flow—thanks to groundbreaking research on apple and grape skin stem cells.
It starts with a question: Why do some people maintain warm extremities and steady blood pressure as they age, while others feel perpetually chilled and run-down?
Researchers found a key piece of the puzzle in the polyphenols naturally locked inside certain apple and grape skin stem cells—not your typical store-bought grapes or apples, but specialized extracts clinically studied for their effect on nitric oxide (NO).
Why nitric oxide? Because NO is like your body’s “master switch” for relaxed, open blood vessels.
When it’s plentiful, blood flows more freely, carrying oxygen and nutrients to every cell.
But many older adults produce less nitric oxide, or break it down too quickly, leading to cold hands and feet, fatigue, and creeping blood pressure numbers.
Ever wonder why your hands and feet only started turning frigid in recent years?
Part of the reason is that by the time you’re 50, you’ve lost up to 60% of your body’s ability to produce nitric oxide (NO)—the molecule your vessels rely on for healthy, relaxed blood flow.
When NO output plummets, those vessels can constrict, slowing circulation and leaving fingers and toes frosty.
Now, researchers have identified a breakthrough to tackle this head-on: apple and grape “fruit stem cells,” clinically standardized for the potent polyphenols they contain.
These unique extracts—known as ViNitrox®—can help reignite nitric oxide production. In other words, they deliver a powerful push to help restore what age has taken away, supporting vessels in opening up and allowing nourishing blood to flow to your extremities.
Polyphenols Trigger NO Production – Think of them as messengers, telling your body, “It’s time to make nitric oxide!”
They Protect NO from Rapid Breakdown – Because stress and oxidative damage can degrade NO quickly, these fruit-derived antioxidants help preserve it for longer, so you can feel the difference in warmth and energy.
They’re Clinically Studied – Unlike run-of-the-mill extracts, the fruit stem cell polyphenols in ViNitrox® have been rigorously tested in the lab and humans for their effects on circulation and blood pressure—making them a true game-changer for anyone 50+ who’s noticed that “cold hand, cold feet” syndrome starting to creep in.
Imagine picking grapes and apples at the peak of their potency—then capturing the most powerful compounds locked inside their stem cells.
That’s precisely what happens with ViNitrox®, a specialized extract derived from apple and grape fruit stem cells. These stem cells are meticulously standardized for polyphenols, the key nutrients that help spark and sustain nitric oxide.
Here’s why that matters for you:
Unleashes Your Natural Warmth
Polyphenols in these stem cells don’t just increase your body’s nitric oxide; they also help defend it against the daily wear and tear that breaks NO down. The result? Steadier blood flow and a real chance to say goodbye to those frigid fingers and toes.
Targets the Real Bottleneck
Many circulation boosters ignore one crucial fact: If nitric oxide isn’t protected, it quickly vanishes. By harnessing these fruit stem cells, ViNitrox® tackles the entire chain—creating NO and then shielding it so it can work longer and harder for you.
Clinically Proven Ingredients
Far from a fleeting health fad, these carefully sourced stem cells are backed by rigorous human studies, showing measurable improvements in circulation, stamina, and comfort. It’s a level of scientific pedigree that run-of-the-mill fruit extracts simply can’t match.
With the highly potent polyphenols you get from the apple and grape skin stem cells, you’re not getting a random “miracle” ingredient—you’re getting a precision-engineered synergy designed to help your body do what it does best: circulate warm, nourishing blood from head to toe.
Let’s be clear: OxyBoost isn’t about waving around one “magic bullet” nutrient.
Instead, it brings together fruit stem cells (ViNitrox®) and beet root powder to address every stage of healthy circulation:
Kick-Start Nitric Oxide Production – The polyphenols in apple and grape stem cells encourage your body to generate more NO, helping blood vessels relax so warm, oxygen-rich blood can flow freely.
Maintain & Protect NO – Beet root is renowned for providing nitrates, which your body converts into additional nitric oxide. These two powerhouses combine to amplify and preserve NO levels longer than a single nutrient alone ever could.
Boost Total Circulatory Health – When your blood vessels stay flexible and open, you get not only warmer hands and feet, but also a potential lift in energy and more comfortable blood pressure—all day long.
In other words, OxyBoost doesn’t rely on one flashy ingredient. It’s a carefully designed synergy—uniting potent fruit stem cells with beet root to help you recapture the warmth, energy, and vitality you deserve.
OxyBoost does more than just drop a single nutrient into your system. It brings fruit stem cell polyphenols (ViNitrox®) and beet root powder together in a dynamic one-two punch for healthier circulation:
Jump-Start Nitric Oxide
Apple and grape stem cells supercharge your body’s NO production, helping arteries relax so life-giving blood can move into your fingers, toes, and everywhere in between.
Keep NO Working Longer
Beet root powder adds natural nitrates that bolster and extend nitric oxide’s lifespan. Instead of vanishing quickly, NO stays active, supporting a comfortable blood pressure and delivering a pleasant warmth throughout your body.
Deliver Whole-Body Benefits
Better blood flow means cells get more oxygen. For you, that can mean sharper energy, warmer extremities, and a sense of freedom from the constant worry about circulation.
By uniting these potent ingredients, OxyBoost ensures you get the full advantage of fruit stem cells—and keeps the nitric oxide engine firing—so you can rediscover the warmth and vitality that make life more enjoyable.
You shouldn’t have to rely on guesswork or hype when it comes to your circulation. That’s why the fruit stem cells (ViNitrox®) in OxyBoost have been put to the test—under real clinical conditions:
ViNitrox™ dilated blood vessels by 50% - nearly matching the power of laboratory chemicals specifically designed for circulation1,2
A 28-day study with 34 participants showed a dramatic 50% reduction in inflammation
The blood flow improvements were 10 times greater than those seen with traditional L-arginine supplements
The effects were achieved with a specific 500mg dose - the exact amount needed for optimal results
These weren't just laboratory results. Real people in the studies reported experiencing:
Significant increases in energy
Better exercise performance
Improved overall wellbeing
The scientific community took notice. While traditional supplements were struggling to achieve even a 5% improvement in blood flow, ViNitrox™ was showing consistent 50% improvements in clinical settings.
Here's what makes ViNitrox revolutionary:

For years, the “nitric oxide story” revolved around L-arginine. How many times have you been told, “Take arginine; it’s all you need!”? Guess what? You’ve been misled.
Laughably Small Impact
In scientific studies, L-arginine alone might boost blood flow by a pathetic 1.8%–5%—barely enough to warm a baby’s fingertips, let alone rescue your ice-cold hands or help maintain healthy blood pressure.
Potentially Worse Than Nothing
Excess arginine can mutate into toxic byproducts that attack your endothelial cells—the delicate “key masters” of nitric oxide. Instead of supporting your arteries, you could be pummeling them!
No Game Plan for NO Breakdown
Even if arginine squeaks out a little nitric oxide, it offers zero protection against the oxidative stress that destroys NO in minutes. That means the fleeting improvement can vanish long before you ever feel it.
Are you beginning to see how L-arginine “alone” might be a huge waste of your hard-earned cash—and possibly your precious health?
You’ve felt the letdown before—some supplement or diet plan that promised the moon, only to leave you with still-frigid feet and a wallet full of disappointment. It’s no wonder folks are suspicious.
But OxyBoost was created for people exactly like you, who are sick and tired of solutions that don’t deliver.
That’s why we combined the jaw-dropping science of fruit stem cells—those polyphenol-rich extracts proven to ignite and safeguard nitric oxide—with the natural nitrates in beet root to bring you a synergy that single-ingredient formulas simply can’t match.
The results have been nothing short of remarkable for thousands of customers.
Neil, age 62, was skeptical at first. As a dedicated gym-goer, he'd tried everything to maintain his energy levels.
"I've been taking this for a couple of weeks," he reports, "and the difference is remarkable. I used to struggle to finish my workouts. Now, not only do I feel good at the end, but I could go another 4-5 minutes. It's like I've gotten 15 years of my life back."
Shannon Davis, a medical researcher, decided to put OxyBoost to the scientific test:
"I used Nitric Oxide Indicator Strips to measure my nitric oxide levels before and after. Within two days, I went from the 'Low' range to the 'Optimal' range. As a researcher, I was amazed. The science actually works."
“I’ve Tried Arginine in other Circulation Boosters Before—Didn’t Help!”
Exactly. That’s because arginine alone is rarely enough because it boosts blood flow by just 1.8% on average. The synergy in OxyBoost—fruit skin stem cells + beet nitrates—boosts blood flow by 50%, addressing the root problem (generating and protecting nitric oxide) so your body actually feels the difference.
“Is It Okay to Take if I’m Over 60?”
We specifically designed OxyBoost for adults who’ve seen their nitric oxide levels nosedive over the decades. Clinical trials show the fruit stem cell polyphenols in OxyBoost™ can be safe and effective, but always check with your doc if you have specific health concerns.
“Supplements Are So Hit-and-Miss—I Don’t Want More Junk.”
We refuse to peddle “hype.” Either OxyBoost truly warms your fingers and toes and helps keep your BP comfortable—or you get every penny back. Simple.
Every day that passes, your body's ability to produce nitric oxide continues to decline. The cells responsible for producing this vital molecule become more damaged, making it harder to restore them to optimal function.
