Complete & Advanced Pet & Farm Animal Health Solution

D’OXYVA® (deoxyhemoglobin vasodilator) offers the latest technology for complete health, and greatly improves the performance of pets such as dogs, and farm animals such as horses. The fully mechanical, noninvasive, and painless applicator is fast and easy to administer and clinically validated to significantly improve a range of physiological functions. It achieves exceptional outcomes by significantly improving blood circulation and certain nerve functions such as the rest and digest (parasympathetic), and thereby treating and preventing serious medical conditions. It is also highly beneficial for oral, fur, muscle, bone, and heart health for young and old animals alike.
D’OXYVA’s handheld, non-electrical applicator gently delivers its proprietary supersaturated vapor solution on the surface of the skin in a few minutes to provide long lasting major benefits. Each single 5-minute application on a thumb or near an affected body part provides over 4 hours of circulatory, neurological and other benefits for speeding up chronic pain relief, healing of diabetic foot wounds, spider and varicose veins besides other major outcomes to an average of 4-8 weeks, according to several high quality human studies*.

D'OXYVA® is a safe and amazing health solution for pets and farm animals

D’OXYVA  is the answer to all your dog’s health requirements, from a healthy coat to healthy cardiovascular system, mental functions, and dental hygiene. Based on the latest scientific evidence, D’OXYVA was developed to transform animal health markets around the world and the method in which pets like dogs and farm animals like horses are treated as we presently know it.

For instance, as a species, dogs have strong physiological and genetic resemblances to humans, sharing more than 80 percent genetic similarity with humans, against only 67 percent for mice. The rate of cancer diagnosed in dogs is on the rise, as is cancer diagnoses in humans. In fact, canine cancer has become the leading cause of death in dogs over the past years, and the disease responds the same way to treatments.

Applying D’OXYVA daily provides for a complete health solution for pets and farm animals because it beneficially affects the ANS (autonomic nervous system) which governs all internal organ functions outside of conscious control. The ANS has two main fractions in the brain with two, unlike functions. One is the parasympathetic nervous system, involved in the “rest and digest” functions. This reduces heart rate, calms the animal, and promotes cardiovascular health.

The importance of medical gas (e.g., CO2, Nobel-winner O2, Nobel-winner NO) in health solutions for farm animals and pets is quite similar to its role in human health. In a controlled study, D’OXYVA has recorded outsized, sustained, and reproducible results in race horses; 100-300% improvement from absolute baseline lasting over 90 minutes in micro-vascular skin perfusion pressure as measured by Moor Instruments FDA-cleared continuous blood flow monitor. In another case study, D’OXYVA healed laminitis for a multi-million-dollar race horse in a few weeks.

Why Use D'OXYVA?

D’OXYVA® (deoxyhemoglobin vasodilator)  is a handheld applicator, which is the first biotech solution of its kind backed by widely-established groundbreaking Nobel Prize-winning science.  It is validated to significantly improve macro- and micro-circulation of blood flow and certain nerve activities in the body, which together are widely reported to form an effective non-invasive, pain-free solution option for many conditions.

For example, D’OXYVA® naturally delivers remarkable and fast pain management results without the use of opioids. In high quality studies, it has been demonstrating noticeable efficacy in the reduction and elimination of chronic pain — achieving over 90%* elimination of all varieties of chronic pain in nearly all enrolled subjects either the same day or in a few days.


D’OXYVA is the only fully noninvasive, completely painless transdermal (over-the-skin) microcirculatory solution that has been studied in high quality pivotal human trials to significantly improve microcirculation.

D’OXYVA’s significant improvement of microcirculation, i.e., blood flow to the smallest blood vessels, benefits one’s health, immune system and overall sense of well-being in a variety of ways.

most frequent questions and answers


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).

Search the terms we use on this site on the internet to learn more and measure your own results at home or with your doctor with a pulse oximeter for one example. Then watch your blood oxygen (SpO2) and perfusion index (peripheral blood flow) rise quickly in just a half an hour and hour that stays elevated for several hours after a single 5-minute D’OXYVA (single 16g cartridge)! Measure results with your blood pressure and blood glucose meter. For example, take it before your workout to boost energy and after for rapid recovery. Take it to restore healthy blood flow for your foot wounds or back pain or headaches. Reduce the risks of major infections, chronic illnesses and skin damage.

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.
