Reviews For CircO2^® Nitric Oxide

I bought it about a month ago and went in for my check up. The Dr. said that I now have something showing up that may be a renal problem. She told me to stop taking it. I go back in a week for another check to see if anything is different. Will update after.

"Trying to return bottles/jars!! Need address for returned to you. TKS MARINAN BREWER"

I have one more tablet left too take in the second container the test strips says optimal IÆm having urinating problem which IÆm taking medication for which is not working to good urgents problem. So I donÆt know how I should feel taking this medication IÆm 89 years old if that gives you clue

I bought the product about 6 weeks ago and not sure about its affect.. I have been using the 'test' strips and they don't show any difference from when I started which was between the depleted and low stage. I was hoping to see an improvement, but not yet. I have one more box and will test again when I get to that.

I returned because I didn't notice any difference. Also, thought it was overpriced. Am waiting for my credit to my credit card.

I've been taking it for a bit over a month. I think is still early to notice a big difference

"I bought 3 boxes, to give this a try but noticed that my tongue was getting sore, so I stopped after consuming one box. I measured my NO level about one week after taking the last tablet and it was very good. Maybe I should have tested it before I took the tablets as well. My tongue is back to normal and I donÆt think I will take anymore tablets..."

I bought this a month ago. Took it every morning before eating. Still had a low level on the last before taking it. I would not buy it again.

I do not feel any different since I started the Product. My Nitric level increased slightly when using the test strips.

I experienced some positive effects from this product after taking two boxes with a lengthy interval in between. The expense of continuing the dosage non-stop was prohibitive. For both boxes the effects of energy and blood flow were felt with the first few doses, but not the later doses. That made me wonder if the natural hormonal regulation of the NO cycle kicks in eventually to partly negate the effect of the supplement so as to maintain homeostasis. If so, maybe a layoff between boxes is advisable. That is the case for a number of herbal supplements.. Maybe worth a study?
