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.
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.


We're so confident CircO2 will transform how you feel, we offer a "Down to the Last Lozenge" guarantee.
