CircO2 *
I was amazed at how quickly and wonderfully my BP became normal after taking CircO2 tabs that dissolve quickly on my tongue. Nitric oxide is an important natural agent in our bodies that helps to maintain normal dilation of our blood vessels which promotes normal blood flow and oxygen delivery throughout our bodies. I also think that circO2 is a much more effective form of nitric oxide than having to swallow a capsule or pill.
