Reviews For CircO2^® Nitric Oxide

I have been on this for about 3 weeks. I have seen no change in my life.

I took this supplement for over a month, and I saw no difference.

I was unable to feel any improvement or difference with the use of this formulation.

I was hoping for increased energy and less fatigue and there was no change.

In the first week my tongue blew up like a balloon .I could not eat anything. I wasn't sure initially if it was the culprit as I take a large amount of supplements. As soon as I stopped my tongue settled down and I continued to not taking Circ02 for a week. Then I gave it another try and immediately my tongue started to react - badly so I spit it out. I was so sad as oxygen is what I require as I am in my 80's. I threw it all out never thinking my oldest daughter had just started using it and was fine. I have never had a bad reaction to anything in my whole life. I looked carefully at the ingredients and nothing there seemed wrong but something was wrong for me

I couldn’t feel any difference so I returned the unused portion and got a refund.

Took the supplement to see improved O2 level. Am tested monthly when visiting oncologist in Flagstaff. When on Circ02 my level actually went down not up. Disappointed with results.

I was excited and looking forward to trying this supplement after reading about the benefits I could get from it. I tried it two times and the effect on my tongue and throat was painful.

Package suggests taking product 1-2 times daily. I have been taking once a day for 3 weeks & have seen no results. I started taking it twice daily for only a few days & need time to see if it benefits me.

Well I have followed the instructions and nothing has changed at all !! Very unhappy customer !
