Everyone with an active lifestyle has experienced the benefit of improved blood circulation, and Circularity has developed a one-of-a-kind,  industry-leading,  advanced metabolic weight loss, athletic performance and injury recovery solution to magnify those benefits with outsized results.


Are you taking needle shots, medications and supplements to help lose weight and improve your performance (e.g., Nitric Oxide)?

Then you will love the ultra-purified medical CO2 delivered by the latest non-irritating, non-toxic, and fully non-invasive transdermal infusion technology called D’OXYVA®  (deoxyhemoglobin vasodilator). 


Nitric Oxide (NO) is marketed all over for its benefits, yet CO2 does far more for the body and until recently has been ignored. It wasn’t until Circularity Healthcare found a gentle, fast and effective way to deliver CO2 over the skin and over the counter that the real benefits could be discovered.


D’OXYVA is not considered doping according to the United States Anti-Doping Agency (USADA).



“I am seeing an increase in muscle mass due to the D’OXYVA. I feel great. Thanks, Dr. Jim” – Dr. Jim Bledsoe from Pensacola, FL United States


“I have found that after only two weeks of using the D’OXYVA system daily that my metabolism has increased and is helping me to lose weight. My sex drive has increased and I am sleeping better throughout the night.” –Judy Trocha from Pollock Pines, CA United States

Taking D’OXYVA daily promotes benefits related to significantly improved blood circulation, including significantly increased cardiac activity, physical fitness, metabolism, endurance, energy balance and a healthy weight.


If you depend on exercise to bolster your circulation and metabolism in order to lose weight, then supplement your efforts with D’OXYVA’s microcirculatory blood flow solution.



Subjects who used D’OXYVA’s athletic injury recovery solution regularly also reported significant muscle pain relief and much stronger vitals during physician checkups than with any other modality they have already tried. 

D’OXYVA significantly improves oxygenated blood flow, skin perfusion, parasympathetic nerve activity and strengthen microcirculation for hours at a time, based on various published and unpublished clinical evidence. These significant physiological enhancements all lead to outsized performance and clinical outcomes.


After a 5-minute administration, users in various clinical trials recorded dramatic improvements of often two or three times from baseline in macro-, and microcirculatory blood flow for often well over 4 hours afterward.


Pro athletes and casual sport enthusiasts reported significant improvements in body weight, stamina, energy, and recovery in 2 to 4 weeks with a single 5-minute delivery daily.


In controlled human clinical trials, D’OXYVA’s microcirculatory solution has demonstrated remarkable improvements in heart rate, skin receptor signaling, the autonomic nervous system, full body skeletal tissue perfusion, and other vital physiological functions that lead to higher metabolic activity.

Take two 16g cartridges each day, in the morning and at night for the first month. Measure your results of blood flow and performance then adjust dosing accordingly to one per day in the second month.

For maintenance, take two or three 16g cartridges each week for as long as you can. Continue engaging with your physical activities to improve results.

Additional benefits when taking D’OXYVA daily may include, but are not limited to:

Increase and improved muscle size and body tone, enhanced cardiac function


Significant, fast physical performance increase and pain relief


Significantly improved mental acuity; concentration, problem solving, eye-hand coordination


Promoting relaxation and managing stress


Metabolic weight loss as a result of improved circulation and metabolism


Enhanced absorption of skin & body enhancing products through the increase of blood circulation in the skin tissues
