CircO2 OXYGEN BOOSTER *
By Janet D. (SUNLAND, CA) - 10/6/2016
I love this product! I now work three jobs, do yoga, martial arts, and I'm 62 years old. I have researched many supplements, and keep on top of my eating habits to help me to keep up my stamina and my immune system functioning well. I did notice a slight shortness of breath when I would walk uphill, so I decided to try your product, which boosts oxygen and circulation. I feel much better and do not get tired easily , my body feels stronger now than when I was in my forties. I love the test strips that come with the product that tests your levels of oxygen in your body[ mine tested very low before taking the product, and now I'm good.} I will definitely be reordering soon, as delivering oxygen to the cells is vital in the healing process of the body and brain.

By Diane G. (Canada ) - 9/30/2016
I noticed within days that my circulation improved and I was much more alert. The test strips are very helpful too. I was at a nearly depleted level. I'm on the rise - thank you. I will be reordering this supplement.

I recommend CircO2 by Advanced Bionutritionals *
By Evelia M. (Beavercreek, OH) - 9/29/2016
I've been taking CircO2 for some time now, and while the test strip only shows "low", it's better than "depleted". At 83 I find it hard to remember to take a second one in the middle of the afternoon, so I guess I'll have to be satisfied with that.

I normally get a spark of life down there *
By Bruce W. (Taylorville, IL) - 1/19/2026
When I first started taking these tablets a few years ago I was taking it every day and I had an adverse reaction in my eye site that caused blurriness and a ruptured ruptured capillary. I was getting too much blood in the eyes. I dialed it back to 5 days a week and after about 2½ years I have had no more eye issues and it helps with my male issues.
