Reviews For CircO2^® Nitric Oxide

I'm a 74 yr old cyclist. Over the past few years, I have been noticing a gradual decline in my ability to go longer distances at a reasonable pace. Of course, a certain amount of decline is 'expected' due to age. Then I tried CircO2, and began to notice a gradual improvement. Now my ability is once again more dependent on my training instead of my advancing age. At this age, I get a constant bombardment of products pitched; you would think that given enough money, I should be able to live forever in perfect health. It is just nice to find at least one product that seems to do what it says it will.

Circ02 seems to improve my nighttime breathing; it is easy to take, no detectable side effects.

CircO2 has made a Great difference, I'm not mentally or physically drifting off for a cat nap. Thank You Advanced.

All your products are great but this is my favorite. I always feel more alive and awake after taking it.

Had high blood pressure for several years. Started circo2 and within 5 days my blood pressure went from 160/ 85 to 110 /65. I would recommend circo2 to anyone with high blood pressure to try Circo2!

I’ve taken Circ02 for the past few years, and have noticed that my energy level has improved over that period of time. It’s my opinion that Circ02 is one of the most valuable supplements available.

I've been taking one lozenge each morning I do feel more energetic and I will I'm sure continue taking them. Thanks

My circulation in my hands and feet have improved since I've been on this.

I am very pleased with the continued results, as is my doctor. So easy to take. Chewable always a better option than capsule or tablet.

I'm 72 years old and I've been taking CircO2 for the past 5 weeks and notice better circulation in my hands and arms while sleeping at night.
