Millions of adults over 50 are quietly losing the “youth molecule” that keeps blood vessels open, oxygen flowing and the brain firing…
Nitric oxide is the signal your body uses to deliver oxygen and nutrients to every cell.
And research shows its levels fall dramatically with age — about 75% by age 70 and 85% by age 80.
Why You Need Nitric Oxide
Low energy that keeps you from the activities you love, and afternoons that feel heavier than they should.
Numbers your doctor keeps monitoring as circulation changes with age.
Frustrating memory lapses and a mental edge that is harder to hold onto.
Less performance and confidence in the bedroom as blood flow declines.
Stiffness and discomfort that limit your independence.
A classic sign of poor circulation reaching your extremities.
The MIT Breakthrough
Starts in Your Mouth
MIT scientists found that nitric oxide production begins with the bacteria on your tongue. That’s why CircO2 is a fast-dissolving lozenge: place one on your tongue and the process kicks off within minutes. In clinical testing, this method raised nitric oxide levels 200% in 20 minutes and increased blood flow by 34%.*

Why Most Nitric Oxide Supplements Fail
Studies show L-arginine can lose up to 75% of its potency during digestion, and after 45 the body struggles to convert it to nitric oxide.
Effective, but you would need 2–3 pounds daily for therapeutic effects, and potency varies with the soil they grew in.
They go straight to the stomach, yet the first and most crucial step of nitric oxide production does not happen in your gut.
The CircO2 Formula
6 Nutrients, One Lozenge
A favorite of Olympic athletes, rich in natural nitrates that help open blood vessels, improve oxygen flow and support stamina.
Used for centuries to support the heart, and now known to enhance nitric oxide absorption so you get more out of every dose.
Converts to nitric oxide more effectively than L-arginine, especially after 45. Supports circulation, memory and performance.
After 50, up to 30% of adults become B12 deficient. B12 supports energy, nerve health and nitric oxide production.
Acts as a catalyst for nitric oxide production and helps protect existing nitric oxide from oxidative damage.
Helps relax blood vessels, supports a regular heart rhythm and aids recovery.

Still Undecided? Top Questions Answered
The ingredients have a long history of safety, and we have never received reports of serious side effects. Because the formula relaxes blood vessels and improves blood flow, people with low blood pressure should consult their physician before taking CircO2.
Some people feel an effect in minutes; others notice changes in the first days and more after a week or two. Each person responds differently. If you don’t notice a difference, keep taking it until the box is finished, backed by the 90-day guarantee.
Keep doing what you’re doing! Even with healthy habits, endothelial function declines with age. CircO2 helps support the endothelium, so you can keep your circulation healthy as you get older.
Good oral hygiene matters. You can switch to natural, fluoride-free products, but you don’t need to: the lozenge dissolves in your mouth, giving it time to mix with the special bacteria and start making nitric oxide.
Many people do well with one lozenge in the morning. We suggest twice a day for the first week or two, then trying once in the morning to see how you feel. It’s best to let it dissolve completely, but you may chew the rest after it has dissolved a bit.
No. CircO2 contains no caffeine or artificial stimulants. It supports blood flow, so what you feel is natural energy.
