Published studies reveal that popular L-arginine-based blood flow boosters only increase circulation by 1.8-10%, far less than what some companies claim. Worse yet, these boosters could be damaging the very cells that produce nitric oxide (see how below).
OxyBoost™ contains proprietary polyphenols extracted from fruit stem cells that are clinically proven to be 10X more effective than the competition in improving blood flow... Helping people to feel YEARS younger!

As Seen In
Nitric oxide is a molecule that opens your arteries and stimulates oxygen and nutrient-rich blood flow to your body's organs & cells.
As we age, we lose 85% of our body's ability to produce nitric oxide.
This loss of nitric oxide results in the aging process and chronic diseases and maladies associated with aging.
Nitric oxide production can be stimulated with certain foods, exercise and the supplementation of certain nutrients
Large doses (7,000mg) of L-arginine, an amino acid supplement, can dilate the cardiovascular system on average 1.8% for a few hours. Large doses of arginine have negative side effects. The most popular nitric oxide boosters are primarily L-arginine-based.7
Watch the short video above to hear Dr. Louis J. Ignarro, PhD
(one of the three Nobel prize winning scientists) explain what a lack of nitric oxide does to the body.
"I am convinced that nitric oxide can age proof your cardiovascular system, keeping it much fitter than your chronological age would indicate. Now we know we can help the cardiovascular system naturally — with the body’s internally manufactured “wonder drug”, nitric oxide (N.O.)."
"As we age, our nitric oxide (N.O.) levels steadily decline. Along with the aging process and declining N.O. levels comes increased risk for many disorders and diseases, including hypertension, heart attack, stroke, dementia, and erectile dysfunction."

French scientists from the highly regarded Bio Seare Laboratoires understood that certain chemicals (polyphenols) in the stem cells of apples and grape skins called “gallolated catechins” possessed powerful antioxidant, antibacterial, anti-inflammatory and vasodilating properties.
But there was a problem.
These remarkable compounds - special polyphenols that could fight inflammation, boost circulation, and help protect against common health problems associated with aging - were locked away inside microscopic fruit stem cells, impossible to reach with conventional methods.
For years, the elite research team at Bio Seare Laboratoires worked tirelessly to crack this biological vault. They knew that if they could successfully extract these compounds, they would have something revolutionary on their hands.
Then came the breakthrough. Using pioneering extraction technology, they finally discovered how to isolate and concentrate these powerful molecules in their purest form.
They called their discovery ViNitrox™. And it would change everything we thought we knew about natural circulatory health.
An animal clinical study compared the dilating effects of OxyBoosts active ingredient ViNitrox™ at a 500mg dose against a laboratory artificial chemical called Leucocyanidol, which is specifically designed to dilate blood vessels1,2.
The results showed ViNitrox™ dilated blood vessels by 50%, almost as much as the lab chemical, which makes it the most powerful NATURAL nitric oxide booster on the market.
The most common nitric booster on the market is L-arginine, which boosts circulation between 1.8% to 5%. This makes the blood flow effects of OxyBoost more than 10x greater than the leading competitor.
Bottom Line:
OxyBoosts key ingredient ViNitrox boost circulation by 50%
Most nitric oxide boosters on the market boost circulation by 1.8% to 5% 7
A monocentric, double blind against placebo, randomized, clinical study was conducted to see the anti-inflammatory effects of ViNitrox.
34 persons with metabolic syndrome were used in this study. A dosage of 500mg was given (the same amount found in OxyBoost and OxySpark) over 28 days.
The study showed a significant reduction in inflammation by 50%.
This is also important as it shows the apple and grape skin stem cells protect against free radicals, which are created when nitric oxide is produced.
Bottom Line:
OxyBoost's key ingredient, ViNitrox™ reduces inflammation by up to 50%
OxyBoost contains powerful antioxidants that also boost the immune system
Most nitric oxide "boosters" today use L-arginine as the main part of their formula.
Clinical studies show a therapeutic 7,000mg (7g) dose of L-arginine only increases circulation by an average 1.8% - 5% within a few hours7.
To make matters worse, continual use of arginine eventually requires more and more arginine to maintain the average 1.8% vasodilation level.
After months of continuous use, L-arginine begins to damage the cells that produce nitric oxide.
This damage leads to the premature death of those cells, called "cell senescence."
As those cells die at an accelerated rate, the need for nitric oxide increases.
Bottom line: Don't use L-arginine nitric oxide boosters.

Important: Why We Recommend At Least 3 Bottles To Start
As you age, your circulatory system's endothelial cells, where Nitric Oxide is produced, become damaged and lose 85% of their ability to generate Nitric Oxide. It takes 30 days for OxyBoost, at four capsules per day (two-30 serving bottles), to help repair the endothelial cells (Repair Phase) so they can consistently produce Nitric Oxide at near youthful levels.
Thereafter, only one dose of OxyBoost per day (one bottle per month) is required to maintain (Maintenance Phase) those new, higher Nitric Oxide levels. So, depending on where you are in your Nitric Oxide restoration quest, you have three purchasing options from which to choose. Remember our 90-Day, "Empty Bottle" No-Risk Money-Back GUARANTEE.
Once you place your order, you'll receive your OxyBoost within 2-5 business days if you live in the United Sates. Free USPS Ground Advantage Shipping only available in the U.S.
Note: OxyBoost's Active Ingredients, ViNitrox & Beet Root Extract, are also contained in our powdered drink product OxySpark. In addition, OxySpark contains nutrients such as: L-Citrulline; Beet Root Extract; Ubiquinol C0Q10; AstraGin; Enzogenol; Vitamins C, D3, E, K2 B6, B12; Niacin; Biotin; Magnesium; Zinc; Selinium and Trace Minerals.
Many of our customers use both OxySpark (morning drink) and OxyBoost capsules in the afternoon for increased energy.

I had heard about nitric oxide benefits and was taping my mouth shut at night, so the body, it is said, would make more of the nitric oxide by nose breathing! It was an ok experience.
Seeing the oxyspark ad intrigued me. I purchased the product and began using it! I am 72 year old women, and I immediately felt the energy increase, and I can’t do without this amazing product!! Love love love it!!! Thankyou!!
