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:

Increase nitric oxide levels by 24%
Improve circulation by 50%
Reduce inflammation by 50%
Neutralize harmful free radicals

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.

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

OxyBoost helps your body produce more nitric oxide, a critical molecule that relaxes and widens blood vessels. Better circulation means better performance, endurance, and cardiovascular support.
Promotes vascular flexibility for easier blood flow and less resistance.

Supports endothelial function, the inner lining of blood vessels that regulates pressure.

Aids nutrient delivery to vital organs like your brain, heart, and muscles.

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:

  • In a controlled laboratory study, they compared ViNitrox to leucocyanidol - a synthetic chemical specifically designed by pharmaceutical companies to dilate blood vessels. 1

  • ViNitrox performed almost as well as the lab-made drug.

  • The blood vessels dilated by an incredible 50%. 1

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:


  • 9.7% boost in endurance 2

  • 12.8% better effort tolerance 2

  • 16.2% improved recovery 2


These gains were from just one dose—imagine daily use!

My results from using Oxyboost

I'm a born skeptic! So I don't trust ads that I find on the internet, but the Oxyboost ad that talked about "cold hands and feet" caught my attention. That has been a "problem" of mine for quite some time. I have used gloves and socks to try to get them warm, but it always seem to be coming from "inside" my body.
I figured that it was then poor circulation that was a causing my problem.
I started reading about this product, and the testimonials from users, and that was what convinced me to try your product.
I have been taking them for 2 weeks now, and I am convinced that the pills are doing what you have advertised them to do. I have more energy and warmer hands. Some skeptics might think this to be a "placebo" effect, but I don't think that is the case with Oxyboost! I am pleasantly surprised by the effects I am getting from Oxyboost and will be buying more when my supplies run low.

I’ve been an OxyBoost customer for many years and I’m totally satisfied with the product OxyNaturals gives me. I like to stay in shape with exercise and eating right. In today’s world much of our food is filled with pesticide's and I try to counter much of it with eating right and taking vitamins. OxyBoost is all natural and that appeals to me. I give it a big thumbs up!
