Nitric Oxide for Healthy Immune Function

Nitric Oxide for Healthy Immune Function
October 3, 2025Blog

October marks the beginning of Fall. The weather turns cooler, the days get shorter, the leaves turn color, begin to fall and it also marks the beginning of seasonal viral infections.

As the weather turns cooler and less sunlight each day, more people are spending more time indoors in close quarters. The perfect recipe for transmission of respiratory viruses. As long as there has been life on Earth, we humans have been exposed to viruses. Healthy people typically are resistant to viral infections. On the contrary, the unhealthy, feeble and particularly the elderly are more susceptible to viral infections and illness from the infection.

The past 100 years has witnessed a scientific wave of new understandings of our immune system and how our body is designed to deal with chronic pathogens, including viruses and bacteria. Each year for the past 100 years there are an estimated 12,000-52,000 deaths in the U.S. alone. During the 1918 -1919 Great Influenza pandemic, there were more than 675,000 deaths in the U.S.

The introductions of the seasonal flu vaccines have really had minimal effects on reducing the number of deaths from flu each year. Therefore, I thought it would be timely to explain how adequate and sufficient nitric oxide production can protect you from the seasonal flu and all other infections, including bacterial to keep you healthy during this time of year and throughout the year.

 

The Link Between Circulation and Immunity

I remember taking a Pathology course years ago and there was an important concept that was presented. This concept is presented on page 58 of Robbins Pathology: “Well vascularized tissues are more resistant to infections and capable of localizing/containing offending agents. By contrast, poorly vascularized tissues are relatively inefficient in responding to inflammatory stimuli.” This essentially means that if you have good circulation and healthy, clean blood vessels, your body can effectively fight and kill any infections before they have a chance to make you sick.

Well, we know that nitric oxide is the key to good circulation and keeps our blood vessels clean, healthy and functional. Furthermore, we know that it is the loss of nitric oxide production that leads to poorly vascularized tissues and increased risk of infections. Let’s explore the scientific explanation of why and how this happens.

If we have poor circulation that means we have a weakened immune response. Our white blood cells (neutrophils and macrophages) along with antibodies, which are the body’s primary defense against pathogens, are dependent upon our cardiovascular system to be delivered to the sites of infection. With poor circulation, these infection-fighting cells cannot reach the primary site of infection, allowing bacteria and viruses to multiply with little opposition.

 

Why Oxygen and Nitric Oxide Work Hand in Hand

Poor circulation leads to reduced oxygen delivery and supply (hypoxia). Oxygen is critical for the proper function of our immune cells to produce oxygen radicals to kill bacteria and viruses. A lack of oxygen also inhibits our cell’s ability to produce nitric oxide. Nitric oxide is known to prevent virus replication, and nitric oxide shuts down bacterial respiration. We need oxygen to make nitric oxide and we need nitric oxide to deliver oxygen. Houston, we have a problem.

Inadequate circulation leads to an accumulation of waste products. The circulatory system transports oxygen and nutrients but also is responsible for removing cellular debris, toxins, and other waste from a wound or site of infection. When circulation is poor, these waste products up, creating a toxic acidic environment that further impedes healing and promotes infection.

Without good circulation we cannot deliver antibiotics or other medicines to the site of infection. For an established infection, antibiotics delivered via the bloodstream cannot reach the affected tissue in high enough concentrations to be effective. This can render antibiotic treatments useless and allow the infection to worsen. Think about your Amazon order but the delivery truck getting stuck in traffic and unable to deliver the goods. This is what happens to our immune system without adequate nitric oxide.

 

Daily Habits to Boost Nitric Oxide and Immunity

We have a very clear understanding of what makes certain people susceptible to infections and a very clear understanding of what makes some people resistant to infections. I am one of those apparently resistant to infections. I have not had the flu in over 25 years. I never contracted COVID and rarely do I get sick. Most importantly, I do not take any shots or vaccines.

However, I do focus every day on optimizing my nitric oxide production, maintaining good circulation and tissue oxygenation. This is something anyone and everyone can and should do, especially this time of year, and especially if you are elderly and not in good health. Below are my daily habits. I strongly encourage anyone reading this to incorporate and avoid getting sick this fall and winter.

  1. Take a daily nitric oxide supplement that produces nitric oxide gas. If your body has lost the ability to produce nitric oxide naturally, my nitric oxide releasing lozenges provide it for you. Beets are not nitric oxide, unless they are my fermented beets.
  2. Workout every day. I start my day with a 10-15-minute workout with stretching. I do 100 squats, 100 push ups and 7-8 minutes of movement and stretching. This will increase your heart rate, breath rate and get your blood flow going.
  3. Try to get at least 30 minutes of direct sunlight every day. I try to catch the first sunlight of the day. Sunlight is the best disinfectant.
  4. Use an infrared sauna. I use my sauna every day but especially if I feel my body is getting weak and feel illness coming on. Our body naturally produces a fever when we get an infection. That increased heat helps our body kill off infections. I use an infrared sauna at 170 degrees Fahrenheit for 30 minutes with an ozone generator inside the sauna. This heat and ozone combined creates an environment where viruses and bacteria cannot survive. If you start to feel like you are getting sick, go find a sauna and most importantly do not take any medication to suppress the fever.
  5. Practice deep breathing through the nose. Respiratory viruses enter through our sinuses and can penetrate our lungs. Part of our body’s natural defense is the production of nitric oxide through our epithelial cells in our sinuses. If we incorporate at least 3-5 minutes of deep nasal breathing exercises each day, we activate nitric oxide production and help kills off any viruses or bacteria that may have entered our pulmonary system.
  6. Practice gratitude and give thanks to God. Each day we live is a gift and we should be grateful for this gift. If we live each day with a servant’s heart and positive attitude, we have better health.

Nitric oxide is a foundational molecule for optimal health and disease prevention. Science is clear. Those who are deficient in nitric oxide or compromised in their ability to naturally produce it are more prone and susceptible to illness. It is not just infectious disease but cardiovascular disease, which remains the number one killer of men and women worldwide.

I have spent the past 25 years discovering ways to improve our nitric oxide production leading to a longer healthier life free of disease. Our product portfolio is safe, effective and affordable for anyone looking to improve their health. The combination of our nitric oxide releasing lozenges, fermented beet powder and our latest Cardiosmile toothpaste should be a daily practice for everyone in the world who wants to live a better and healthier life. Give us a try and let us help you.

Most if not all chronic diseases, including cardiovascular disease (the number one killer of men and women worldwide) are characterized and associated with loss of nitric oxide production.
