Nitric Oxide production decreases with age and is rapidly decreased after age 40. N1O1 Nitric Oxide Lozenges are designed to work with your body and help support nitric oxide production.

Developed by Dr. Nathan Bryan, the world’s leading expert on Nitric Oxide, this nitric oxide-generating supplement is specially formulated to rapidly help boost the body’s natural Nitric Oxide production.

This innovative formula uses an advanced delivery system that provides an exogenous source of Nitric Oxide that supports the following:

  • Improve Nitric Oxide production
  • Enhance oxygen and nutrient delivery to cells
  • Support cardiovascular health
  • Aid normal heart function
  • Support healthy blood circulation and blood pressure
  • Create healthy blood flow to the brain and other organs
  • Deliver antioxidant support
  • Support cognitive function and memory

N1O1 Nitric Oxide Lozenges are backed by 20+ years of research and technology from an internationally recognized biochemist and physiologist, Dr. Bryan, who was the first to discover natural product chemistry for the production of nitric oxide. The result of his research is the most powerful Nitric Oxide enhancer on the market!

Why does the lozenge need to dissolve?

N1O1 is an orally disintegrating lozenge. It’s designed to release Nitric Oxide as it dissolves in the mouth.

Should I take this if I'm pregnant or nursing? What if I have other medications or medical issues? 

Consult with your doctor before use if you are:

  • Pregnant
  • Nursing
  • Taking medication
  • Taking organic nitrates
  • Taking phosphodiesterase inhibitors
  • Having difficulty swallowing
  • Diagnosed with a medical condition

What if I become dizzy or faint?

Discontinue use if you experience dizziness or fainting, which could be the result of low blood pressure.

Do I need to refrigerate or store in a special way?

N1O1 should be stored in a dry place that’s kept at room temperature. Keep the container tightly closed at all times and never use if the clear seal is broken or missing prior to purchase. N1O1 is for adult use only. Always store in a place that is out of the reach of children. 

What if the tablet color changes?

The supplements may change color over time naturally, but this in no way alters the effectiveness of the product.

Less convenient, but tastes better

This nitric oxide solution isn't as convenient as the old product and its packaging--the individual 'packets' were great for traveling. But this new nitric oxide product tastes better and definitely has the same impact on my circulation. I just put a few tablets in a small ziplock to travel with. I'm starting to see nitric oxide mentioned more and more and I love that Dr. Tennant has had it for years.

Love how it's 20 bucks cheaper

Thanks to Dr T for offering a great NO solution; I take it every day for better circulation. And I love how it's $20 cheaper than Neo40 Professional!
