Reviews For CircO2^® Nitric Oxide

you stopped the 'test strips, I stop your product ! Simple enough !

I don't know and I don't think so because the test strip is always very light pink.

I have been taking cir02 for several months, but have not observed any benefit. I tested my saliva with their strip before taking this supplement and I was depleted. After one month of diligently taking the product on daily basis, I still tested depleted. And I am still depleted after several months. I have written Advanced Bionutritionals several times to inquire why this product is not working for me, but no response from them, instead they keep emailing me adverts of the benefits of this product. I wish they can respond to my questions, and would love to speak with them over the phone, I tried calling but can't reach them. I bought a lot of this product and still taking them on daily. I have never missed a day since I started. I am only taking them with hope it might work for me some day as I know the benefits of Nitric Oxide. I still have 5 boxes left as I ordered a lot from them after listening to their presentation. I will continue taking them but will not order more. The excitement made me to buy a lot at one time, but unfortunately this product has not worked for me,

I have been taking full dose (2daily) for four months. When I use test strip I am still showing as depleted level.

I’m still waiting for some result only been taking it for a month, so hope I see some results on the second month.

After taking this stuff I noticed NO DIFFERENCE so why bother with taking CircO2!!

I am a medical professional and have tired to measure the effects of Circ02. When I ordered this product they said they were going to send some litmus strips to check the efficacy. Those did not come in the order. I have a pulse ox machine and I took a baseline reading multiple times a day and then at the same times with CircO2. There has been no difference. Also, I don't feel any different or any improvements. I'd like to see some solid studies on this product where there is no conflict of interest. Maybe that way I could get a better idea of how to measure the effects.

We have been taking CIRO2 for about 3 weeks and neither of us have seen any improvement in the bedroom or blood pressure. We are in our 70s so this may be the problem, but we are still hopeful. Cannot recommend it at this time, but hope to in the future.

I really haven’t felt a difference. My bp hasn’t dropped & I haven’t felt any increase in energy. I have an O2 tester & there’s no change.

I have not felt any change since taking this product mainly got it to improve blood pressure but if anything it has gone up not happy yet
