Discover the Science Behind D'OXYVA
D’OXYVA® (deoxyhemoglobin vasodilator) is the only fully non-invasive, non-irritating, non-opioid, and completely painless, skin delivery (over-the-skin) nerve stimulant and microcirculatory solution.
With over seven years of industry-leading research results, D’OXYVA® demonstrated that it does not break the skin’s barrier while it provides outsized quality of life and outcomes quickly and affordably.
In short, based on current leading neurology, immunology, microvascular, and cellular oxygenation science, D’OXYVA® is leading the field by:
- Significantly lowering the risk of diabetes and cardiovascular complications.
- Providing complete significant improvement of difficult wounds together with major pain relief and improved quality of life.
D’OXYVA®‘s gentle vapor solution with purified CO2 readily dissolves in a molecular form in the skin, acting as a catalyst to improve skin perfusion pressure and optimize nerve functions and microcirculation.
D’OXYVA® delivers fast solution to the areas you need it most. It’s also easy-to-use virtually anywhere — even from the comfort and privacy of your own home.
Significant results in 4-8 weeks*
D'OXYVA Once a day, 5 Days/Week

Over two dozen studies demonstrated sterling results at clinics and at home with zero adverse events.
D’OXYVA® (deoxyhemoglobin vasodilator) has recorded significant results, delivering major outcomes for well over 90% of users.
Average results rounded for display, based on number of enrolled subjects in each study with D’OXYVA® and user feedback.
Ask your doctor before taking D’OXYVA®.
We will refund your entire D’OXYVA® purchase price if you do not achieve any improvements (proof of purchase required, improvements of blood flow (perfusion index) measured from absolute baseline without taking D’OXYVA®).

Correct. That’s why D’OXYVA’s gentle process demonstrated that it does NOT significantly increase the CO2 content in the blood or tissue and instead reduces the CO2 content per partial pressure of oxygen (O2). This just means D’OXYVA oxygenates the blood and tissue due to inducing the beneficial Bohr effect. In addition, CO2 is a so-called gasotransmitter that signals the autonomic nervous system in the brain to launch protective mechanisms that tend to move a host of critical functions into balance (homeostasis).
Simply by reducing the need to spend on expensive modalities that just don’t work at the underlying problem, they only act as an expensive bandaid. However, with the help of D’OXYVA your body gets to the bottom of the problem and starts regulating critical functions to restore order and even generate new and highly beneficial resources such as vessel structure growth, tissue repair, cell production and other hormonal and neural functions. Take D’OXYVA together with your beloved supplements, vitamins and even necessary medications and treatments to boost their efficacy and likely reduce any negative effects you may be experiencing from some of them.
