Why Thousands of People Are Switching To OxySpark
If you struggle with fatigue, brain fog, cold hands and feet, or high blood pressure…OxySpark could be exactly what your body’s been missing.
Most circulation and nitric oxide supplements rely on L-Arginine, a synthetic amino acid that only boosts blood flow for a few hours, but it can cause dangerous side effects, including heart issues and digestive problems.
That’s why more and more people over 50 — along with athletes and health-conscious adults — are ditching arginine-based supplements and turning to OxySpark instead.
Backed by Nobel Prize-winning research, OxySpark uses ViNitrox™️, a natural blend of apple and grape polyphenols that are clinically proven to:
Boost circulation 50%
Safely increase nitric oxide production by 24%
Increase energy levels to combat fatigue
Enhance exercise performance and recovery
Reduce inflammation by 50%
It's time to stop filling your body with harmful supplements that contain L-Arginine.
OxySpark delivers 10x the effectiveness of typical arginine supplements with 100% natural, science-backed ingredients.

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.7
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.17
OxySpark works without L-Arginine. It contains clinically studied, natural ingredients that are proven to boost nitric oxide by 24%, improve heart health, and increase circulation by 50%.
It’s a smarter, plant-based formula thousands of people your age are already using to improve energy, heart, and brain health.
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, OxySpark uses a clinically studied, low-dose ViNitrox™ formula that works better and faster, naturally.
Boosts Circulation & Heart Health
OxySpark 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, OxySpark 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
OxySpark 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.

OxySpark's Proprietary All-Natural Ingredients In A Great-Tasting Grape Flavor
OxySpark combines a proprietary blend of natural, non-GMO, gluten-free ingredients with ViNitrox™, a clinically studied compound proven to enhance nitric oxide production and vasodilation more effectively than typical arginine-based supplements.
While most nitric oxide boosters taste bitter or synthetic, OxySpark delivers a naturally sweet grape flavor you’ll actually enjoy, no choking it down, no aftertaste.
Just mix one scoop with 8 oz. of water or milk, and you’ll soon start feeling the refreshing, energizing, and circulation-boosting effects of a nitric oxide formula that’s as clean as it is effective.
Rated 4.8/5 by over 29,000+ Satisfied Customers
Clinical Studies Validate The Power Of OxySpark
OxySpark is supported by both clinical research and the real-world success stories of thousands of users.
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 that is in OxySpark and 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 other blood flow 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!

What People Are Saying About OxySpark…
Customer Reviews
I thought it might be valuable to future prospective customers to know what I think about your tremendous products. I am a retired 80-year-old Doctor of Science (D.Sc.) biochemist and former national trainer for years for other nutrition products firms since the 1970's when I also was the youngest scientist speaker for the National Health Federation conventions and other organizations, and a university administrator. I am a consumer of only the finest nutritional products.
As soon as I evaluated your OxySpark formula I ordered a case of it the next day and recommend it to all my clients. No other formula in this industry has such a comprehensive formula that is remarkably effective for the generation of whole-body sustained energy generation at cellular level for increased stamina and endurance with no negative side effects or without the typical crash found in other supplements. It provides an extra energy spark to my life that is soft and smooth without being hyper.
Personally, for me I outwork and exercise people 1/3 my age every day and I also speed walk 7 miles 5 days a week. This firm's total product line is so remarkable and well researched that I would recommend them to anyone else just as I do to my own high-performance clients. Everyone comments on my brilliant memory and high energy performance as I still work full time for the joy of helping others in their senior years and being a mentor to young people as well. My own physician says I have the best chance of all their patients over the years to live to age 100 and that I didn't need to see them for any health issue.
I now prescribe OxySpark to my patients because it worked wonders for me. Thave a long standing history of heart disease in my family (my father died of heart attack at 58 yrs). When I turned 58, my blood pressure was through the roof (180/110). With OxySpark my blood pressure has normalized and | have lower cholesterol/triglyceride levels. Plus, OxySpark gives me tons more energy. OxySpark will change your life as it has mine - and you feel it happening.
I am 88 years old and take no meds just good healthy Oxy Spark, Oxy Boast and Mem Niva and I feel great and my memory good, Thank you.
C Elaine Sharp
Have only used one jar, delicious taste, easy to prepare
There I was doing so good for a 76 year old on my energy levels. So I more or less dropped OxySpark. It didn't take it for awhile. It wan't very long before my energy levels dropped. I Came to the conclusion (duh) I need OxySpark every day twice. Makes me happy to have energy to make it through the day.
