Ultraviolet Blood Irradiation (UVBI) – Supporting Immunity and Cellular Health
Ultraviolet Blood Irradiation (UVBI) – Supporting Immunity and Cellular Health

Ultraviolet Blood Irradiation (UVBI) is a therapeutic procedure that uses ultraviolet light to stimulate the body’s immune system, support cellular health, and enhance detoxification. Developed in the 1920s and used successfully through the mid-20th century to treat infectious diseases, UVBI is gaining renewed interest in the field of integrative and functional medicine. With its unique ability to modulate immune responses without pharmaceuticals, UVBI presents a valuable option for patients dealing with chronic illness, inflammation, or immune dysfunction.
This minimally invasive technique involves drawing a small volume of blood, exposing it to specific wavelengths of ultraviolet light, and then re-infusing it into the body. The goal is to energize immune cells, neutralize pathogens, and promote systemic healing.
How Ultraviolet Blood Irradiation (UVBI) Works
During a typical UVBI session, about 60–250 mL of a patient’s blood is withdrawn through an IV and circulated through a UV light device. This machine uses a sterile quartz cuvette that allows ultraviolet light—primarily UV-C, with some UV-A and UV-B—to penetrate the blood. The exposure damages the DNA of viruses, bacteria, and fungi, rendering them inactive while also stimulating white blood cells and increasing the production of signaling molecules like cytokines.
Once treated, the blood is returned to the body in a closed-loop system. This process activates immune modulation, boosts oxygen delivery to tissues, enhances detox pathways, and encourages cellular repair.
Unlike conventional therapies that suppress symptoms, UVBI works by supporting the body’s own defense systems—making it a powerful adjunct to a broader health strategy.
Clinical Benefits of Ultraviolet Blood Irradiation
Ultraviolet Blood Irradiation is used in functional medicine for its wide range of systemic benefits. While it is not a stand-alone cure, many patients undergoing UVBI as part of a broader treatment plan report noticeable improvements in symptoms and overall wellbeing. Benefits may include:
- Improved Immune Function: UVBI can enhance immune surveillance and regulation, helping the body mount more appropriate responses to infections and inflammation.
- Reduction in Inflammatory Markers: Clinical observations suggest that UVBI can help reduce chronic inflammation, which plays a role in many degenerative diseases.
- Increased Oxygenation and Circulation: UV light exposure may improve red blood cell flexibility and oxygen-carrying capacity, supporting tissue health.
- Detoxification Support: By reducing the load of pathogens and supporting lymphatic function, UVBI may ease the burden on detoxification organs such as the liver and kidneys.
- Microbial Clearance: UVBI is especially useful in managing chronic or treatment-resistant infections, including Lyme disease, Epstein-Barr virus (EBV), and mold-related illness.
For patients with conditions like chronic fatigue syndrome, fibromyalgia, long-haul viral symptoms, or autoimmune disorders, UVBI may provide symptom relief and improve quality of life when used alongside other therapies.
UVBI vs. Ozone Therapy: What’s the Difference?
Ultraviolet Blood Irradiation and ozone therapy are often paired in clinical settings, but they operate through different biological mechanisms. Ozone therapy introduces ozone (O₃) into the blood to create a controlled oxidative response that can stimulate mitochondria and enhance cellular metabolism.
UVBI, on the other hand, uses light energy to stimulate immune and circulatory effects without introducing any chemical agents. It works more subtly, targeting cellular communication and immune signaling.
Some clinics combine UVBI and ozone therapy for synergistic effects, especially when treating infections or complex immune disorders. However, UVBI can also be used as a stand-alone option, particularly for individuals sensitive to ozone or those seeking a non-chemical intervention.
What to Expect During a UVBI Session
A UVBI treatment is typically conducted in a clinic equipped with sterile, medical-grade devices. Sessions usually last between 45 and 60 minutes and involve minimal discomfort. The process includes:
- Initial IV Placement: A vein is accessed, and blood is drawn into a sterile tube or bag.
- Irradiation Phase: The blood passes through a UV chamber where it is exposed to the appropriate light wavelength.
- Reinfusion: The treated blood is returned to the body through the same IV line.
Most patients report little to no side effects, aside from the standard brief pinch of the needle. Some may feel energized, more alert, or experience a sense of relaxation following the session. Depending on the condition being addressed, a treatment plan may consist of several sessions over weeks or months.
Who May Benefit From Ultraviolet Blood Irradiation?
UVBI is not targeted toward a specific disease—it supports the body systemically. This makes it especially attractive for individuals with complex or difficult-to-treat conditions. Potential candidates include those dealing with:
- Persistent bacterial or viral infections (e.g., Lyme disease, EBV, long COVID)
- Immune dysregulation or autoimmune diseases (e.g., lupus, rheumatoid arthritis)
- Chronic fatigue or fibromyalgia
- Detoxification challenges due to mold, environmental toxins, or heavy metals
- Post-surgical recovery or general wellness support
Because UVBI has a low incidence of side effects, it is often used as a complementary approach within personalized health plans.
Is UVBI Safe and Legal?
While UVBI is not FDA-approved for specific diseases, it is legally offered in many integrative and functional medicine clinics across the United States under physician supervision. The equipment used is medical-grade, and procedures are performed with sterile technique.
Before initiating treatment, providers typically conduct a full health evaluation, including medical history, lab testing, and a review of contraindications. UVBI is generally considered safe, though caution is advised for individuals with:
- Photosensitivity disorders (e.g., lupus or porphyria)
- Bleeding disorders or low platelet count
- Uncontrolled cardiovascular conditions
As with any medical treatment, UVBI should be administered by licensed professionals trained in its proper use and safety protocols.
Ultraviolet Blood Irradiation offers a powerful, drug-free approach to immune and cellular support. As more patients seek holistic solutions to chronic health issues, UVBI stands out as a promising therapy for those ready to explore integrative paths to healing.
