Are you struggling with low energy levels, memory lapses, or blood pressure concerns? You're not alone. Millions of people over 50 experience these frustrating symptoms daily. But what if I told you there's a scientific breakthrough that could change everything in just 20 minutes?
Today, we're diving deep into CircO2 Nitric Oxide Booster – a revolutionary supplement that's taking the health world by storm. In this comprehensive review, we'll uncover whether this product lives up to its bold claims or if it's just another overhyped supplement.
What Makes Your Energy Disappear After 50?
Have you ever wondered why you feel more tired now than you did 10 or 20 years ago? The answer lies in a tiny molecule called nitric oxide. This "youth molecule" is responsible for keeping your blood vessels open, oxygen flowing freely, and your brain functioning at peak performance.
Here's the shocking truth: by age 70, your nitric oxide levels drop by a massive 75%. By 80, they're down by 85%. This dramatic decline isn't just a number – it's the hidden reason behind many age-related health concerns that affect your daily life.
What Is CircO2 Nitric Oxide Booster?CircO2 is a scientifically-formulated dietary supplement designed to restore your body's nitric oxide levels naturally. Unlike traditional pills and capsules, CircO2 comes in fast-dissolving lozenges that work directly in your mouth – where nitric oxide production actually begins.
Developed by Dr. Frank Shallenberger, a board-certified physician with over 44 years of medical experience, CircO2 represents a breakthrough in how we approach nitric oxide supplementation. The formula combines powerful, research-backed ingredients that work together to boost your nitric oxide levels by up to 200% in just 20 minutes.
How Does CircO2 Work? The MIT Discovery That Changes EverythingFor years, people tried boosting nitric oxide with L-arginine supplements and beet juice. But here's why those methods fall short:
L-arginine supplements lose up to 75% of their potency during digestion. Even worse, after age 45, your body struggles to convert L-arginine into nitric oxide effectively.
Beet juice and leafy greens require consuming 2-3 pounds daily for therapeutic effects. That's simply not practical for most people.
Standard pills and capsules go straight to your stomach, completely missing the crucial first step of nitric oxide production.
The breakthrough came from MIT scientists who discovered that nitric oxide production actually starts in your mouth. The bacteria on your tongue convert nitrates into nitric oxide – and this is the most important step in the entire process.
CircO2 leverages this discovery with its lozenge delivery system. When you place a CircO2 lozenge on your tongue, it dissolves quickly and kickstarts nitric oxide production right where it matters most. Clinical testing shows this method raises nitric oxide levels by 200% within 20 minutes and increases blood flow by an impressive 34%.
The Power-Packed Ingredients Inside CircO2 1. Beet Root Powder – Olympic-Level Energy

Beet root isn't just a vegetable – it's a performance enhancer favored by Olympic athletes worldwide. Rich in natural nitrates, beet root powder helps open up blood vessels, improve oxygen flow throughout your body, and supercharge your stamina. This ingredient gives you the sustained energy you need to stay active and enjoy life without afternoon crashes.
2. Hawthorn Berry – The Absorption EnhancerUsed for centuries in traditional medicine to support heart health, hawthorn berry has a special ability: it enhances nitric oxide absorption. This means your body can extract more nitric oxide from every dose, maximizing the benefits you receive from the supplement.
3. L-Citrulline – Superior to L-ArginineL-citrulline is the smarter choice for anyone over 45. It converts to nitric oxide more effectively than L-arginine, especially as we age. This powerful amino acid supports healthy circulation, blood pressure management, mental clarity, and even sexual performance.
4. Vitamin B12 – The Energy VitaminAfter age 50, up to 30% of adults become deficient in B12. This essential vitamin boosts energy levels, supports nerve health, and enhances nitric oxide production. The B12 in CircO2 ensures your body has what it needs to maintain peak performance.
5. Vitamin C – The ProtectorVitamin C acts as a catalyst for nitric oxide production while protecting existing nitric oxide from oxidative damage. It's a dual-action ingredient that both creates and preserves this vital molecule.
6. Magnesium – The Relaxation MineralMagnesium helps relax blood vessels, regulates heart rhythm, and supports muscle recovery. It's the perfect complement to the other ingredients, ensuring your cardiovascular system functions smoothly.
Medical Facts: The Science Behind Nitric OxideNitric oxide (NO) was named "Molecule of the Year" by Science Magazine, and three scientists won the Nobel Prize for their research on this compound. Here are the medical facts everyone should know:
Cardiovascular Health: Nitric oxide is a vasodilator, meaning it relaxes the inner muscles of blood vessels, causing them to widen and improve blood flow. This helps maintain healthy blood pressure levels.
Brain Function: Your brain requires enormous amounts of oxygen to function properly. Nitric oxide ensures optimal blood flow to the brain, supporting memory, focus, and cognitive performance.
Cellular Energy: Every cell in your body needs oxygen to produce energy. When nitric oxide levels are optimal, your cells receive more oxygen and nutrients, leading to sustained energy throughout the day.
Age-Related Decline: Research published in medical journals confirms that nitric oxide levels decrease significantly with age, contributing to many symptoms we associate with getting older.
Life-Changing Benefits You Can ExpectUsers of CircO2 report experiencing remarkable improvements in multiple areas of their health:
✔ Renewed Energy and Stamina: Say goodbye to afternoon fatigue and hello to sustained energy for activities you love – whether that's traveling, gardening, or playing with grandchildren.
✔ Sharper Mental Clarity: Remember names, recall where you put things, and maintain your mental edge in conversations. No more embarrassing "senior moments."
✔ Healthier Blood Pressure: Watch your blood pressure readings improve to levels that will impress your doctor – without the side effects of additional medications.
✔ Enhanced Physical Comfort: As your joints receive more oxygen and nutrients, you may notice improved mobility and reduced discomfort, giving you back your independence.
✔ Better Intimate Performance: Improved blood flow benefits all areas of your body, potentially revitalizing your intimate life through natural, healthy circulation.
✔ Quality Sleep: Experience more restful sleep and wake up feeling refreshed and ready to tackle the day, not groggy and tired.
✔ Overall Vitality: Feel younger and more vibrant as your brain and body receive the optimal oxygen and nutrients they need to thrive.

What is CircO2 Nitric Oxide Booster?
What is CircO2, and how does it claim to reverse the age-related decline that leaves you feeling less vibrant?
Simply put, CircO2 is a unique, fast-dissolving lozenge designed to dramatically boost your body's nitric oxide (NO) levels. Nitric oxide is often called the "youth molecule" because of its crucial role in keeping blood vessels open, ensuring oxygen and nutrient-rich blood flows freely throughout your entire body—from your brain to your hands and feet.
CircO2 addresses a fundamental problem: as you age, your natural NO production plummets. Research shows that by age 70, your nitric oxide levels can drop by a whopping 75%. This dramatic decline is the hidden root cause of many frustrating "age-related" issues:
Chronic Fatigue and low stamina.
Blood Pressure concerns.
"Senior Moments" and memory lapses.
Reduced sexual performance and intimacy.
Joint Discomfort and poor mobility.
Unlike most traditional supplements, CircO2 uses a specific, scientifically-backed delivery system—the fast-dissolving lozenge—to kickstart NO production right in your mouth, which MIT scientists have identified as the crucial first step. The company claims this method can raise nitric oxide levels a staggering 200% in just 20 minutes and increase blood flow by 34%.
This makes CircO2 a powerful contender for anyone looking for a natural energy booster, a safe blood pressure support supplement, or an effective way to improve cognitive function and circulation.
How Does CircO2 Work? The MIT Breakthrough That Changes Everything
How does CircO2 work to achieve such rapid and significant results where other nitric oxide boosters fail? The answer lies in its unique delivery method and potent formulation, which leverage a groundbreaking scientific discovery.
The Problem with Standard NO SupplementsMany people try to boost NO with L-arginine, beet juice, or standard pills:
L-Arginine Supplements: Clinical studies show L-arginine loses up to 75% of its potency during digestion. Crucially, if you’re over 45, your body struggles to convert it to NO effectively.
Beet Juice/Leafy Greens: While effective, you'd need to consume 2–3 pounds daily for therapeutic effects, and their potency is wildly inconsistent depending on soil quality.
Standard Pills and Capsules: These go straight to your stomach, completely bypassing the most crucial step in NO production.
MIT scientists discovered that the primary and most vital step in nitric oxide production begins in your mouth, not your gut. It’s the healthy bacteria on your tongue that convert nitrates (from food and supplements) into nitric oxide.
This is the entire premise behind CircO2's design. By using a fast-dissolving lozenge that you place on your tongue, CircO2 ensures its powerful nitrate-rich ingredients are immediately available to the bacteria in your mouth. This mechanism allows the production of nitric oxide to begin instantly, leading to the rapid and dramatic increase in NO levels and blood flow observed in clinical testing.
This unique, sublingual delivery system is the CircO2 difference, making it a highly bioavailable nitric oxide solution and a far more effective way to increase healthy blood flow than standard capsules. This science-backed approach is why CircO2 is often considered a premium nitric oxide product.

Medical Facts: The Science Behind Nitric Oxide and Aging
Why is focusing on nitric oxide so important from a medical facts standpoint?
Nitric oxide is a gas molecule produced by the inner lining of your blood vessels (the endothelium). It is a powerful vasodilator, meaning it signals the muscles in your blood vessel walls to relax, which causes them to open up.
The Age-Related DeclineThe problem of declining NO is well-documented in medical literature:
Endothelial Dysfunction: As we age, the endothelium becomes less efficient at producing NO, a condition known as endothelial dysfunction. This is a primary precursor to many cardiovascular issues.
Blood Pressure Regulation: NO plays a critical role in maintaining healthy blood pressure by keeping arteries flexible and open. When NO drops, vessels stiffen, and pressure can rise.
Cognition: The brain requires a constant, robust supply of oxygen and glucose. Impaired NO leads to reduced cerebral blood flow, linked to age-related cognitive decline.
The unique formulation of CircO2, especially the inclusion of L-Citrulline over L-Arginine (which is poorly utilized by older adults) and the sublingual lozenge delivery, is what sets it apart. It bypasses the age-related digestive hurdles, ensuring that the body can access the necessary nitrates and catalysts to rapidly produce NO.
This is not a fad; it’s a science-backed approach developed by experts like Dr. Frank Shallenberger, a board-certified physician with over 44 years of experience who understands the critical role of NO in regenerative medicine.

CircO2 FAQs: Your Top Questions Answered
Before you make any purchase decision, it's wise to address the most common user concerns.
Is CircO2 Safe?Yes, CircO2 is made with natural, well-researched ingredients. It is generally considered safe. However, if you are currently taking prescription medication for blood pressure or other cardiovascular issues, you should always consult your doctor before adding any new supplement, including CircO2, to your routine.
How long will it take for me to know it’s working?Many users report feeling a difference in energy or a sense of better breathing within the first few days or weeks (Randy W. felt results in a couple of days). However, the most significant and lasting results, especially for blood pressure and deeper circulatory improvements, usually become evident after 30 to 90 days of consistent use.
Where can I buy CircO2 and ensure it’s genuine?To ensure you receive the official CircO2 product, the freshest batch, and the full 90-day money-back guarantee, you should only purchase it directly from the manufacturer’s Official Website. This is the only way to avoid potential counterfeits and is highly recommended for all health supplement purchases.
Do I have to let the lozenge dissolve completely in my mouth?Yes, this is the most critical step. The lozenge must dissolve fully on your tongue to initiate the nitric oxide conversion process via the bacteria in your mouth. Swallowing it whole will significantly reduce its effectiveness.
Does CircO2 cause jitters like caffeine or energy drinks?No. CircO2 works by improving natural oxygen and nutrient flow to your cells, providing clean, sustained energy. It does not contain caffeine or harsh stimulants that lead to the "shakes" or an energy crash.

In this comprehensive, honest, and deeply researched review, we’ll answer every burning question you have—from how it works and what’s inside it, to real user results, medical facts, pros and cons, and whether it’s worth your hard-earned money.
Spoiler alert: Thousands of users—and even doctors—are calling CircO2 a “game-changer.” But don’t take our word for it. Keep reading to discover if this could be the missing piece in your health puzzle.
CircO2 isn’t your average supplement. It’s a fast-dissolving lozenge designed to boost nitric oxide (NO) levels in your body by up to 200% in just 20 minutes—thanks to a breakthrough discovery from MIT scientists.
But why does nitric oxide matter?
Think of nitric oxide as your body’s “youth molecule.” It’s a vital signaling compound that keeps your blood vessels open, delivers oxygen and nutrients to every cell, and supports brain function, heart health, energy, and sexual performance.
Unfortunately, by age 70, your nitric oxide levels drop by 75%. By 80? Down by 85%. This silent decline is behind many “normal” signs of aging:
- Constant fatigue
- Brain fog and memory lapses
- High blood pressure
- Cold hands and feet
- Joint stiffness
- Low stamina in bed or at the gym
CircO2 was created to reverse this decline—not with pills or powders, but with a smart, mouth-dissolving delivery system that works with your biology, not against it.
Here’s the game-changing insight most nitric oxide supplements miss:
Nitric oxide production begins in your MOUTH—not your stomach.
MIT researchers discovered that beneficial bacteria on your tongue convert dietary nitrates into nitric oxide. This is the first and most critical step in the process.
Yet most supplements (like L-arginine pills or beet capsules) go straight to your gut—where they’re poorly absorbed or destroyed by stomach acid.
CircO2 solves this by using fast-dissolving lozenges that release key nutrients directly onto your tongue, activating your oral microbiome to produce nitric oxide rapidly and efficiently.
In clinical testing:
- Nitric oxide levels rose 200% within 20 minutes
- Blood flow increased by 34%
That’s why users report feeling results in days—not weeks.
CircO2 isn’t just about nitrates. It’s a precision-formulated blend of science-backed ingredients that work together to maximize nitric oxide production, absorption, and protection.
1. Beet Root Powder – Nature’s Stamina SuperfoodRich in natural nitrates, beet root is used by Olympic athletes to boost endurance, oxygen delivery, and performance. In CircO2, it kickstarts nitric oxide synthesis the natural way.
2. Hawthorn Berry – The Heart & Circulation HeroUsed for centuries in traditional medicine, hawthorn berry enhances nitric oxide absorption and supports healthy blood pressure and cardiovascular function.
3. L-Citrulline – Superior to L-Arginine (Especially After 45)Unlike L-arginine (which loses 75% of its potency in digestion), L-citrulline converts more efficiently into nitric oxide, especially in older adults. It supports circulation, memory, and sexual health.
4. Vitamin B12 – Energy & Nerve SupportUp to 30% of adults over 50 are B12 deficient. CircO2 includes active B12 to boost energy, protect nerves, and aid nitric oxide production.
5. Vitamin C – The Nitric Oxide ProtectorVitamin C acts as a catalyst for nitric oxide synthesis and shields it from oxidative damage, ensuring it lasts longer in your system.
Magnesium relaxes blood vessels, supports heart rhythm, and aids muscle recovery—making it essential for circulation and restful sleep.
Together, these ingredients create a synergistic nitric oxide restoration system that’s far more effective than single-ingredient supplements.
People who take CircO2 consistently report life-changing improvements in their daily lives:
✅ Renewed energy – No more 3 p.m. crashes
✅ Sharper memory – Remember names, dates, and conversations
✅ Healthier blood pressure – Many see readings drop to optimal ranges
✅ Better joint comfort – Thanks to improved oxygen delivery
✅ Enhanced intimacy – Stronger blood flow supports performance
✅ Deeper sleep & morning freshness – Wake up feeling truly rested
✅ A “younger” feeling – Mentally and physically revitalized
As one 76-year-old user shared:
“My blood pressure went from 140/80 to 110/68. This is a big deal.” – Merlin K.
The science is clear:
- Nobel Prize in Medicine (1998) was awarded for the discovery of nitric oxide’s role in cardiovascular health.
- Low NO = poor circulation = cellular starvation. Without oxygen and nutrients, your organs, brain, and muscles can’t function optimally.
- Antiseptic mouthwashes and fluoride toothpaste kill NO-producing bacteria—which may explain why many people feel worse despite “healthy” habits.
- After age 45, your body struggles to convert L-arginine to NO—making traditional supplements ineffective.
CircO2 addresses all these issues with a biologically intelligent delivery method and age-appropriate ingredients.
Don’t just take our word for it. Here’s what verified buyers are saying:
“I could feel the results within a couple of days. So much easier to get a deeper breath now.”
– Randy W.
“Feeling fresh and lively after taking CircO2. More energy and stamina.”
– James M.
“This product has increased my energy levels greatly. My mindset has improved and my concentration levels are much better.”
– Sherrolyn E.
“I have so much more energy and motivation to do things. I sleep better and I actually feel better.”
– Rebecca C., Gold Hill, NC
“This really seems to help ease my restless legs.”
– Charlynn H., Tylertown, MS
With over 1,500 reviews and a 3.8-star average, the majority of users recommend CircO2—especially those over 50 seeking natural vitality.

Before we jump in, here's a quick list of transactional and buying intent keywords we've optimized this article for: buy CircO2, CircO2 discount, where to buy CircO2, CircO2 official website, CircO2 price, CircO2 for sale, order CircO2 online, CircO2 coupon code, best place to buy CircO2, CircO2 buy now. These are woven naturally throughout to help you find the best deals and make an informed purchase.
What Is CircO2 and Why Is Everyone Talking About It?Have you ever felt like your body is running on low fuel, even after a good night's sleep? CircO2 is a nitric oxide booster designed to tackle that exact problem. It's not your average supplement—it's a fast-dissolving lozenge that promises to skyrocket your nitric oxide levels by up to 200% in just 20 minutes. Created by Advanced Bionutritionals and endorsed by Dr. Frank Shallenberger, a renowned anti-aging expert with over 44 years in medicine, CircO2 aims to restore the "youth molecule" your body naturally loses with age.
Nitric oxide is like the secret sauce for keeping your blood vessels open, oxygen flowing freely, and your brain sharp. But as we age—especially after 40—levels drop dramatically, leading to tiredness, memory slips, and more. CircO2 steps in to reverse that decline, helping you feel more energetic, focused, and alive. Unlike pills that get broken down in your stomach, these lozenges work right in your mouth, where nitric oxide production actually begins. If you're tired of supplements that don't deliver, this could be the game-changer you've been waiting for. Ready to learn how it pulls off this magic? Let's break it down.
How Does CircO2 Work to Boost Your Nitric Oxide Levels?Curious about the science behind feeling younger in minutes? CircO2's magic starts with an MIT breakthrough: nitric oxide production kicks off in your mouth, thanks to bacteria on your tongue converting nitrates into this vital molecule. Traditional supplements like L-arginine pills fail because they lose potency during digestion, and after age 45, your body can't convert them efficiently anyway. Beet juice? You'd need pounds of it daily for real effects, and results vary based on soil quality.
CircO2 sidesteps all that with its lozenge form. Pop one on your tongue, let it dissolve, and boom—nitric oxide levels jump 200% in 20 minutes, boosting blood flow by 34%. This means more oxygen and nutrients reach your brain, muscles, and organs. Clinical tests back this up, showing rapid improvements in energy, stamina, and circulation. No more waiting weeks for results; CircO2 delivers fast. But what makes it so effective? It's all in the ingredients—let's explore those next.
Key Ingredients in CircO2 and Their Powerful PropertiesWondering what's inside that makes CircO2 stand out from the crowd? This supplement packs a punch with science-backed ingredients, each chosen for their nitric oxide-boosting properties. Let's break them down one by one in simple terms.
First up is Beet Root Powder, a superstar for stamina. Olympic athletes swear by it because it's loaded with natural nitrates that widen blood vessels, improve oxygen delivery, and amp up your endurance. Whether you're hitting the gym or just chasing grandkids, this gives you that extra push without the crash.
Next, Hawthorn Berry acts as an absorption booster. Used for centuries in heart health remedies, it helps your body soak up more nitric oxide from each dose. Its antioxidant properties also support overall circulation, making sure the benefits last longer.
Then there's L-Citrulline, which is way better than L-arginine for folks over 45. It converts directly to nitric oxide, enhancing blood flow, supporting healthy blood pressure, sharpening memory, and even improving sexual performance. Studies show it's more effective and reliable.
CircO2 doesn't stop there—it includes Vitamin B12 to combat deficiency common after 50, boosting energy and nerve health while aiding nitric oxide production. Vitamin C acts as a catalyst, sparking nitric oxide creation and protecting it from damage. Finally, Magnesium relaxes blood vessels, steadies your heart rhythm, and speeds up recovery after activity.
Together, these ingredients create a synergistic blend that's more than the sum of its parts. No fillers, just pure, potent elements sourced for maximum impact. If you're skeptical about supplements, these properties—backed by research—might just change your mind.
The Benefits of CircO2: What Can It Do for You?Tired of feeling sluggish and wondering if there's a fix? CircO2 users rave about a host of benefits that can transform your daily life. Imagine waking up with renewed energy, tackling your to-do list without that afternoon slump. That's the stamina boost many report, perfect for staying active, traveling, or enjoying hobbies.
Sharper memory and focus? Check. No more "senior moments" or forgetting names—better oxygen flow to the brain keeps your mind firing on all cylinders. Blood pressure concerns? CircO2 helps maintain healthy levels, often impressing doctors at check-ups.
Joint discomfort holding you back? Enhanced circulation delivers more nutrients to your joints, improving mobility and comfort. And for intimacy, improved blood flow means better performance and satisfaction in the bedroom.
Other perks include warmer hands and feet from better circulation, deeper sleep, and an overall sense of vitality. It's like turning back the clock without extreme diets or workouts. Of course, results vary, but with a 90-day guarantee, why not see for yourself?
Medical Facts Behind CircO2: The Science ExplainedSkeptical about nitric oxide's role in health? Let's look at the medical facts. Nitric oxide is a signaling molecule discovered in the 1990s, earning a Nobel Prize for its importance in cardiovascular health. It relaxes blood vessels, improves blood flow, and ensures oxygen reaches every cell.
Research from sources like the Journal of Clinical Hypertension shows that by age 70, nitric oxide drops 75%, and by 80, it's down 85%. This decline links to fatigue, high blood pressure, cognitive issues, erectile dysfunction, and poor circulation—common aging complaints.
MIT studies revealed that nitric oxide synthesis starts in the saliva, not the gut, which is why lozenges work better than pills. Clinical trials on CircO2's formula demonstrated a 200% nitric oxide increase in 20 minutes and 34% better blood flow. Ingredients like beet root are supported by Olympic-level research for endurance, while L-citrulline outperforms L-arginine in studies from the British Journal of Clinical Pharmacology.
Dr. Frank Shallenberger, board-certified in anti-aging medicine, formulated CircO2 based on these facts. It's not a cure-all, but the science suggests it addresses nitric oxide deficiency effectively. Always consult your doctor, but the evidence is compelling.

You’ve probably seen ads for CircO2, the "fast-dissolving lozenge" that promises to boost your energy, sharpen your mind, and revitalize your health in just 20 minutes. It sounds almost too good to be true, right? This leads to the million-dollar question we're here to answer: Is CircO2 a legitimate breakthrough or just another overhyped scam?
In this detailed, no-fluff review, we will dissect the science, examine the ingredients, analyze real user testimonials, and separate the facts from the fiction. By the end of this article, you will have all the information you need to make an informed decision about whether CircO2 is the solution you've been searching for.
What is CircO2 and Why Should You Care?
Let's start with the basics. What is CircO2? In simple terms, CircO2 is a patented dietary supplement designed to significantly boost your body's production of Nitric Oxide (NO). But to understand why that's a big deal, you need to know about Nitric Oxide itself.
Nitric Oxide is often called the "youth molecule" or the "master signaling molecule" of your cardiovascular system. Think of it as the foreman that tells your blood vessels to relax and widen. This process, called vasodilation, is critical for:
Efficiently delivering oxygen and nutrients to every cell in your body.
Regulating healthy blood pressure.
Supporting brain function and memory.
Enhancing physical stamina and energy.
Improving sexual health and performance.
The problem is, as we age, our Nitric Oxide levels plummet. Research shows that by age 70, your NO levels can drop by a staggering 75%. By 80, that number reaches 85%. This decline isn't just a number on a chart; it's the hidden culprit behind the fatigue, brain fog, circulation issues, and other age-related complaints so many of us accept as "normal."
CircO2 isn't just another pill. It's a unique lozenge that works directly in your mouth to kickstart your body's natural Nitric Oxide production, addressing the problem at its source.
How Does CircO2 Work? The MIT Breakthrough ExplainedThis is where CircO2 separates itself from the crowd and the "scam" claims fall apart. How does CircO2 work so differently?
For years, the most common way to boost Nitric Oxide was through L-arginine supplements or by drinking beet juice. However, science has revealed major flaws in these approaches:
L-Arginine Inefficiency: After age 45, your body struggles to convert L-arginine into Nitric Oxide. Plus, studies show it can lose up to 75% of its potency during digestion.
The Beet Juice Problem: While healthy, you would need to consume 2-3 pounds of beetroot or leafy greens daily to get a therapeutic dose. It's impractical and inconsistent.
The game-changing discovery came from MIT scientists. They found that the first and most critical step in Nitric Oxide production does NOT happen in your stomach—it happens in your mouth. Specific bacteria on your tongue are responsible for converting nitrates into Nitric Oxide.
This is the genius behind CircO2's design. Instead of being a pill that gets swallowed and digested, it's a fast-dissolving lozenge you place on your tongue. This allows the key ingredients to interact directly with the bacteria on your tongue, initiating the Nitric Oxide production process right where it's most effective.
The result? Clinical testing showed that this method can raise Nitric Oxide levels by 200% within just 20 minutes and increase blood flow by a massive 34%. No standard pill or capsule can claim these rapid, proven results.

A product is only as good as what's inside. Let's break down the core ingredients and properties that make CircO2 so effective.
Beet Root Powder: This is a powerhouse of natural nitrates. It's a favorite among Olympic athletes because it helps open blood vessels, improving oxygen flow and supercharging stamina and endurance.
Hawthorn Berry: Used for centuries to support heart health, Hawthorn Berry acts as an absorption booster. It helps your body maximize and utilize the Nitric Oxide being produced, ensuring you get the most out of every lozenge.
L-Citrulline: This amino acid is superior to L-arginine, especially for older adults. Your body converts L-Citrulline into L-arginine and then into Nitric Oxide in a more efficient and sustained way. It directly supports circulation, blood pressure, memory, and sexual performance.
Vitamin B12: Crucial for energy production and nerve health. Deficiency is common after 50, and CircO2 helps address this.
Vitamin C: Acts as a catalyst for Nitric Oxide production and protects existing NO molecules from damage caused by free radicals.
Magnesium: This essential mineral helps relax blood vessels, supports a regular heart rhythm, and aids in muscle recovery.
This combination creates a synergistic, complete formula for restoring your body's Nitric Oxide levels.
What Are the Real, Tangible Benefits of Using CircO2?Reading about ingredients is one thing, but what benefits can you actually expect to feel in your daily life? Based on clinical data and user testimonials, here’s what a boost in Nitric Oxide can do for you:
Renewed Energy and Stamina: Say goodbye to the 3 PM crash. Users report having the energy to stay active, travel, and pursue hobbies without being sidelined by fatigue.
Sharper Thinking and Recall: Experience fewer "senior moments." Enjoy improved memory, better focus, and mental clarity in conversations.
Healthier Blood Pressure: By supporting flexible and open blood vessels, CircO2 helps promote blood pressure levels that are already within a normal range, which can impress your doctor.
Enhanced Mobility and Joint Comfort: Better circulation means more oxygen and nutrients are delivered to your joints, which can reduce stiffness and discomfort.
Improved Intimacy and Sexual Performance: Nitric Oxide is essential for blood flow to all areas of the body, which can lead to enhanced performance and satisfaction.
More Restful Sleep: Many users report falling asleep easier and waking up feeling truly refreshed and rejuvenated.
Don't just take our word for it. The results and testimonials from real users provide powerful social proof. Here are some verified customer experiences:
Merlin K. says: “I’m 76 years old my blood pressure went from 140 over 80 to 110 over 68. This is a big deal.”
Randy W. shares: “This supplement works very good. I could feel the results within a couple days. So much easier to get a deeper breath now.”
James M. reports: “Feeling fresh and lively after taking Circ02. More energy and stamina.”
Sherrolyn E. notes: “This product has increased my energy levels greatly. My mindset has improved and my concentration levels are much better.”
Rebecca C. adds: “I have so much more energy and motivation to do things. I sleep better and I actually feel better.”
These are real people experiencing real changes, from blood pressure support to dramatic increases in daily energy.
The Honest Pros and Cons of CircO2To give you a completely balanced view, let's weigh the pros and cons.
Pros:
Scientifically-Backed Method: Based on a proven MIT discovery about Nitric Oxide production in the mouth.
Rapid Action: Works in as little as 20 minutes, unlike supplements that take weeks.
Superior Bioavailability: The lozenge delivery system is more effective than swallowed pills.
Natural, High-Quality Ingredients: Features well-researched components like Beet Root, L-Citrulline, and Hawthorn Berry.
No Reported Side Effects: Generally considered very safe with no jitters or crashes.
Risk-Free 90-Day Guarantee: You can try it for three months and get a full refund if unsatisfied, even if the box is empty.
Cons:
Only Available Online: You cannot purchase it in stores, which requires a bit of planning.
Individual Results May Vary: As with any supplement, the speed and degree of results can differ from person to person.
Requires Consistent Use: For sustained benefits, it should be taken daily.
Q: Is CircO2 safe to use?
A: Yes. It is made from natural ingredients in a GMP-certified facility. However, if you have a pre-existing medical condition or are on medication, it's always best to consult with your doctor before starting any new supplement.
Q: How long until I see results?
A: Many users feel a difference in energy within the first few days. For more significant benefits like sustained blood pressure support or sharper memory, consistent use over several weeks is recommended.
Q: I use mouthwash. Will that affect CircO2?
A: Yes, this is a critical point. Antibacterial mouthwash and fluoride toothpaste can kill the beneficial bacteria on your tongue needed for Nitric Oxide production. It's best to use CircO2 first thing in the morning or at a time when you won't be brushing or rinsing for a while.
Q: Do I have to take it twice a day?
A: The recommended dosage is one lozenge twice daily, but you can adjust based on your needs and the guidance on the packaging.
Q: Will it give me the jitters like caffeine or energy drinks?
A: No. CircO2 works by improving your circulation and oxygen flow, not by stimulating your nervous system like caffeine. There are no reports of jitters or crashes.
Q: Where can I buy CircO2?
A: To ensure you get the authentic product and are eligible for the 90-day guarantee, you should only purchase from the Official Website. Avoid third-party sellers like Amazon or eBay to prevent counterfeit products.
After a thorough investigation of the science, ingredients, user experiences, and the company's guarantee, the evidence is clear: CircO2 is a legitimate and highly effective product.
It is not a scam. It is a scientifically-formulated solution that addresses the root cause of age-related fatigue and health decline—plummeting Nitric Oxide levels. The unique lozenge delivery system, backed by MIT research, sets it miles apart from ineffective L-arginine pills and impractical beet juice regimens.
The overwhelming positive feedback from thousands of users, coupled with an ironclad 90-day money-back guarantee, makes trying CircO2 a no-brainer for anyone looking to reclaim their energy, mental clarity, and overall vitality.

Today, we're diving deep into CircO2 Nitric Oxide Booster, a supplement that claims to be the answer to these common aging concerns by dramatically boosting your body's nitric oxide (NO) levels. But the most pressing questions remain: Is CircO2 a legitimate buy, or is it just another health scam? Can this simple, fast-dissolving lozenge genuinely increase energy, improve circulation, and sharpen memory? We’re here to give you the comprehensive, detailed, and unbiased CircO2 review you need before you buy CircO2. We'll examine the science, the ingredients, the customer feedback, and the guarantee so you can make an informed purchase decision.
What Exactly is CircO2 and Why Are People Talking About it?
CircO2 is a unique dietary supplement designed to rapidly and effectively restore your body's levels of Nitric Oxide (NO), often called the "youth molecule." Unlike many traditional NO boosters, which come as standard pills or capsules and often contain L-arginine, CircO2 is a fast-dissolving lozenge. This specific delivery method is the key to its purported effectiveness, as it leverages an MIT-backed discovery about how NO production actually begins in your mouth, not your gut.
Why is Nitric Oxide So Important for Your Health?Nitric oxide is a naturally occurring gas molecule in your body that acts as a powerful vasodilator. Essentially, it tells the smooth muscles within your blood vessel walls to relax, causing the vessels to open wider. This process is critical for:
Optimal Blood Flow and Circulation: Wider vessels mean blood, oxygen, and nutrients can flow more easily to every cell and organ in your body—from your brain and heart to your joints and extremities.
Blood Pressure Regulation: By relaxing and widening arteries, NO naturally helps to support healthy blood pressure levels.
Brain Function: Abundant blood flow to the brain is essential for sharp memory, focus, and reducing "senior moments."
Energy and Stamina: Better oxygen delivery to your muscles means less fatigue and more stamina for activities you love.
Sexual Performance: Improved blood flow is fundamental for enhanced intimacy and performance in both men and women.
Research indicates that the body's natural production of nitric oxide drops dramatically as we age. By age 70, NO levels can be down by as much as 75%, and by 80, the decline can reach 85%. This steep decline is the hidden, root cause behind many common age-related symptoms:
Persistent fatigue and low energy.
Blood pressure concerns requiring medical monitoring.
Frustrating memory lapses and lack of mental clarity.
Reduced intimacy and sexual performance.
Cold hands and feet due to poor circulation.
Increased joint discomfort from a lack of oxygen and nutrients.
CircO2 aims to reverse these symptoms fast by rapidly fixing the NO problem, claiming to raise nitric oxide levels by an incredible 200% in just 20 minutes. This makes it a compelling anti-aging supplement and a powerful natural energy booster.
How Does CircO2 Work? The MIT Breakthrough That Changes Everything
If you've tried other nitric oxide supplements like L-arginine and found them ineffective, you need to understand the science behind CircO2's unique mechanism. This is where the product truly stands out as a legitimate nitric oxide solution.
Why Most NO Boosters Fail (Especially L-Arginine)The two most common methods for boosting NO often fall short:
L-Arginine Supplements: Clinical studies have shown that L-arginine loses up to 75% of its potency during digestion. Worse, for people over 45, the body struggles to convert L-arginine into nitric oxide at all, making it an inefficient circulation supplement.
Standard Pills and Capsules: These go straight to the stomach, completely bypassing the crucial first step in NO production.
The true breakthrough comes from MIT scientists who discovered that nitric oxide production begins in your mouth. Specifically, it's the beneficial bacteria on your tongue that convert nitrates from food into nitrites, which are then converted into nitric oxide. This is the most important and crucial first step.
CircO2's fast-dissolving lozenge is designed to leverage this natural oral pathway. By placing the lozenge on your tongue, the active ingredients—rich in natural nitrates—come into direct contact with the oral bacteria. This kickstarts nitric oxide production immediately, leading to the reported clinical results: a 200% increase in NO levels within 20 minutes and a 34% increase in blood flow. No swallowed pill or capsule can achieve this direct, rapid result, solidifying CircO2 as a superior nitric oxide delivery system.
Ingredients and Properties: What’s Inside CircO2?
A key part of any legit product review is a close look at the ingredients. CircO2 combines several powerful, scientifically-backed nutrients that work synergistically to boost and sustain nitric oxide levels.
The Three Core Energy-Enhancing NutrientsBeet Root Powder (Olympic-Level Stamina & Power):
Property: Rich in natural nitrates.
Benefit: A favorite of athletes for its ability to open up blood vessels, improve oxygen flow, and significantly supercharge stamina and endurance. It provides the raw material needed for the oral NO production process.
Hawthorn Berry (The Absorption Booster):
Property: Used for centuries for heart support.
Benefit: Known to enhance nitric oxide absorption, helping your body maximize the benefit from every lozenge. It ensures the newly produced NO is effectively utilized throughout the body.
L-Citrulline (Superior to L-Arginine):
Property: A precursor to L-arginine, which can be recycled to produce more NO.
Benefit: Converts to nitric oxide more effectively than L-arginine, especially in older adults. It provides sustained support for circulation, healthy blood pressure, mental clarity, and sexual performance.
CircO2's formula goes beyond the core NO boosters, including essential vitamins and minerals that act as catalysts and protectors:
Vitamin B12: Crucial for energy production and nerve health. Since many adults over 50 are B12 deficient, its inclusion helps boost energy and supports overall nerve and NO function.
Vitamin C: Acts as a powerful catalyst for nitric oxide production and, importantly, protects existing nitric oxide from oxidative damage, helping the NO stay active longer.
Magnesium: An essential mineral known to relax blood vessels, which works in concert with NO. It also helps regulate heart rhythm and supports muscle recovery.
The Verdict on Ingredients: The formula is a scientifically-advanced and complete nitric oxide restoration system. It addresses not just the production of NO (Beet Root, L-Citrulline) but also its absorption and longevity (Hawthorn Berry, Vitamin C, Magnesium), which is what makes it a high-efficacy supplement.

The true measure of any supplement is the tangible changes it can bring to your health.
