Nitric Oxide Levels Jump 200% Higher In Just 20 Minutes

See Website

Boosts your energy, sharpens memory, increases stamina, enhances sexual performance, and helps lower blood pressure.

Nitric oxide is the “youth molecule” your body uses to keep your blood vessels open, oxygen flowing, and brain firing.

But research shows that by age 70 your nitric oxide levels drop by a whopping 75%. By 80, nitric oxide levels are down by 85%.

This dramatic decline is the hidden cause behind:

Fatigue that keeps you from activities you love
Blood pressure concerns your doctor keeps monitoring
"Senior moments" and frustrating memory lapses
Reduced intimacy and performance in the bedroom
Joint discomfort that limits your independence
Cold hands and feet from poor circulation

When nitric oxide plummets, you don't just feel older – your body literally starves for oxygen and nutrients.

The good news? CircO2 fixes your nitric oxide problems in 20 minutes. So you can reverse your symptoms fast.

Why Most “Nitric Oxide” Supplements Fail

The most common ways people try to boost their nitric oxide levels don’t work. Here’s why:

L-arginine supplements

Clinical studies show L-arginine loses up to 75% of its potency during digestion. What’s more, after age 45, your body struggles to convert L-arginine to nitric oxide at all.

Beet juice and leafy greens

While effective, you'd need 2-3 pounds of these foods daily for therapeutic effects. Plus, their nitric oxide-boosting power varies, depending on the soil these plants grew.

Standard pills and capsules

These go straight to your stomach. But MIT scientists found that the first and most crucial step in nitric oxide production does NOT happen in your gut.

The MIT Breakthrough. That Changes Everything

MIT scientists discovered that nitric oxide production starts in your mouth. It’s the bacteria on your tongue that convert nitrates into nitric oxide. That’s the first and most important step.

That’s why CircO2 comes in fast-dissolving lozenges. You place one on your tongue, and within minutes it kickstarts nitric oxide production.

In clinical testing, this method raised nitric oxide levels 200% within 20 minutes. And it increased blood flow by a staggering 34%.

No pill or capsule can achieve these results.

More Nutrients That Multiply the Benefits

CircO2 also includes more ingredients that enhance nitric oxide production:

Vitamin B12

After 50, up to 30% of adults become B12 deficient. The B12 in CircO2 boosts energy, nerve health, and nitric oxide production.

Vitamin C

Acts as a catalyst for nitric oxide production and protects existing nitric oxide from oxidative damage.

Magnesium

Relaxes blood vessels, regulates heart rhythm, and supports recovery.

Together, these ingredients create the most complete, scientifically-advanced nitric oxide restoration system available.
