Reviews For CircO2^® Nitric Oxide

I am a physical educator ,62 years old and owner of a health club in Canada. I have been using CIRCO2 for quite two months and i can feel a great improvement in my energy , my blood pressure and a general well-being. I feel younger and have more stamina to teach my spinning classes ! I recommend strongly!

Wow, using this product has changed my Life. I feel years younger....Great Product.

I've been taking this product for 2 weeks and I definitely feel it working . I have more energy ,sleep better and can feel blood flow down to my feet . I recommend it

The first day I took this product I used the test strip and my nitric oxide was low. I took the product as directed and took my blood pressure later in the day. I was amazed. Lower than it has been in years.Love this product

I’m a 49 year old female runner. I purchased my CircO2 because I am currently training for several Marathons and have been injured and unable to train properly. I started taking my CircO2 several several days before my run. I was expecting a result of around 6 hours to run 26.2 miles. I actually finished in 5 hours and 40 minutes, AND my breathing, body and legs weren’t in their usual state of exhaustion and fatigue!! Looking back at my route I showed I had elevation gains of other 1,000 feet, my quads and calves should have be so tight and full of lactic acid, but they were not!!! ?????? My Garmin watch also tells me my VO2 results, and I raised my level to 37 during this time!! I have no other reasons for such an amazing run with these results and I can’t wait to see how my next two Half and Full Marathons go!!

I have been taking CircO2 for a couple of weeks and I feel I have alot more energy and see more clearly

I feel so much different now than I was before taking CIRC02. I have more energy and able to stay active longer period of time. My blood pressure is normal.

I have used it approximately 9 months. My last Doctor appointment my blood pressure was 121/78 the best it has been in 30 years.

As soon as I started taking CircO2 I felt a difference right away. My energy Level and stamina increased substantially. I really feel during this time of year that oxygenating my blood is even more critical. I am so glad that I discovered CircO2. Thank you!

This vitamin is good and digests good.I like the doseage and it is easy to swallow with water before and after the vitamin recommended or chew.
