Improve Your Circulation & Energy With A Natural, Clinically Proven Nitric Oxide Booster
OxyBoost's fruit stem cell extract formula is proven to increase your circulation, reduce inflammation, and boost nitric oxide naturally without L-Arginine or synthetic stimulants.
Increases your energy naturally without stimulants.
Improves blood flow for better cardiovascular health.
Sharpens focus and memory without putting stress on your system.
Why Thousands of People Are Switching To OxyBoost
If you’re dealing with constant fatigue, brain fog, cold hands and feet, or high blood pressure, OxyBoost may be the perfect choice for you.
Here’s why thousands of people over 50 and athletes are switching to OxyBoost:
Most circulation and nitric oxide supplements rely on L-Arginine, a synthetic amino acid that only boosts blood flow for a few hours but comes with dangerous side effects, including increased risk of heart issues and gastrointestinal distress.
OxyBoost skips L-Arginine completely.
Instead, it uses ViNitrox™, a natural, clinically studied blend of apple and grape skin stem cell polyphenols that’s shown to:
It’s all backed by the Nobel Prize-winning research on nitric oxide from Dr. Louis J. Ignarro, PhD—one of the leading scientists in cardiovascular health.

Exactly What OxyBoost Gives You
Backed by Nobel Prize science, proven by real people.
Support Better Circulation
If you’re in your 50s, your circulation is only 35% compared to when you were younger. OxyBoost is proven to increase your circulation by 50%, helping improve blood flow to your hands, feet, and heart so you feel warmer, lighter, and more mobile without any side effects.
Increase Your Energy Naturally
Are you constantly feeling fatigued? OxyBoost fuels your cells with more oxygen and nutrients so you increase your energy without caffeine or energy crashes.
Reignite Intimacy With Your Partner
Research shows that improved nitric oxide levels support healthy libido and performance, helping you feel confident and connected again, naturally and safely.

WARNING: If Your Blood Flow Supplement Contains L-Arginine, You MUST Stop Taking It Now!
Most blood flow supplements rely on high doses of L-Arginine. Studies show L-Arginine only improves blood flow by an average of 1.8% to 10% and the effect fades within hours.
L-Arginine is an amino acid often used in generic nitric oxide supplements to temporarily dilate blood vessels. But the results are usually short-lived and often come with huge side effects, especially in older adults. Some negative side effects of l-arginine:
Can cause bloating, diarrhea, and stomach cramps
Linked to reactivation of viruses like herpes in sensitive users
Often requires high doses (7,000mg+) for minimal effect
May stress the kidneys and liver with long-term use
Not well tolerated in people over 40 due to declining enzyme activity
Worse, recent studies show L-Arginine’s effectiveness plummets as you age, making it a risky and unreliable long-term solution.
OxyBoost works without L-Arginine. It contains clinically studied, natural ingredients that are proven to boost nitric oxide by 24%, improve circulation by 50%, and reduce inflammation without side effects. It’s a smarter, plant-based formula that supports energy, heart, and brain health as you age.
Natural Way To Improve Your Focus, Increase Energy & Support Heart Health Without L-Arginine
Unlike most nitric oxide boosters that rely on high doses of L-Arginine, OxyBoost uses a clinically studied, low-dose ViNitrox™ formula that works better and faster—naturally.
Boosts Circulation & Heart Health
Supports endothelial function, the inner lining of blood vessels that regulates pressure.
Energizes Without Stimulants
Unlike caffeine-based energy products that spike and crash, OxyBoost provides clean, sustained energy. By naturally improving circulation and oxygenation, your body feels more alert, vital, and energized all day long without the jitters or crashes.
Increases cellular oxygen uptake for better endurance at the source.
Recharges mitochondrial efficiency, your body’s natural energy factories.
Reduces oxidative stress, which can drain your energy quickly.
Supports Mental Clarity & Focus
OxyBoost sharpens mental performance by improving cerebral circulation, allowing you to think clearly, stay focused, and maintain mental stamina, even on demanding days.
Supports neurotransmitter function, helping messages travel faster in your brain.
Combats brain fog and mental fatigue linked to poor blood flow.
Improves blood flow to the brain, enhancing mental clarity and reducing brain fog naturally.

Clinical Studies Validate the Power of OxyBoost™
Backed by science and users alike
Cell Revitalization Breakthrough
When the Bio Seare team first tested their ViNitrox formula, they were amazed by the results, needing three tests to confirm their findings. ViNitrox transforms your body into a nitric oxide-producing powerhouse by activating eNOS (endothelial nitric oxide synthase), your body's nitric oxide factory. 1
In a lab study, ViNitrox boosted eNOS activation by 43% and increased nitric oxide production by 24%, helping cells function like they did years ago. 1 This means ViNitrox not only enhances circulation but also restores your body's natural nitric oxide production.
Blood Flow Restoration
The researchers also discovered something even more important:
Here's the amazing part: ViNitrox works naturally without the side effects of pharmaceuticals. In comparison, L-arginine only dilates blood vessels by 1.8% to 10%, even at high doses of 7,000mg. 2 This makes ViNitrox 5 to 25 times more effective than L-arginine.
Age-Fighting Inflammation Reduction
Here's where it gets interesting. Researchers aimed to understand why ViNitrox outperformed other supplements. They conducted a clinical trial with 34 individuals suffering from metabolic syndrome, each taking 500mg of ViNitrox daily for 28 days, the same amount in OxyBoost.
They found that ViNitrox reduced harmful inflammation by 50%, 3 which is crucial because high inflammation damages the cells that produce nitric oxide. Unlike L-arginine supplements that can worsen inflammation, ViNitrox protects endothelial cells and keeps nitric oxide production steady, making it more effective over time.
Human Performance Enhancement
Dr. Louis Ignarro, Nobel Prize winner, says:
"I am convinced that nitric oxide can age-proof your cardiovascular system, keeping it much fitter than your chronological age would indicate."
ViNitrox enhances your body's nitric oxide production safely. In trials, users experienced:
These gains were from just one dose—imagine daily use!
